On June 1, Marika’s Cards and Gifts had 117 birthday cards on hand. Over the month, Marika’s sold 208 of this type of card and received two orders from the distributor, each for 144 cards. The cost of birthday cards to Marika’s is $0.56 each. What is the value of the inventory at the end of the month?

Answers

Answer 1

Since the cost of each card is $ [tex]0.56[/tex], you can now multiply the total number of cards by the cost per card. the value of the inventory at the end of the month is $ [tex]343.28[/tex].

What is the value of the inventory?

To find the value of the inventory at the end of the month, you need to start by calculating the total number of birthday cards that Marika's Cards and Gifts had at the end of the month.

First, you need to add the number of birthday cards that Marika's sold during the month (208) to the number of cards received from the distributor in two separate orders) [tex](144 \times 2) = 288[/tex]

[tex]117[/tex] (initial inventory) + [tex]208[/tex] (cards sold) +  [tex]288[/tex] (cards received from distributor) =  [tex]613[/tex] (total number of birthday cards at the end of the month)

Since the cost of each card is $0.56, you can now multiply the total number of cards by the cost per card to get the value of the inventory:

[tex]613 \times[/tex] $[tex]0.56 =[/tex] $[tex]343.28[/tex]

Therefore, the value of the inventory at the end of the month is $343.28.

Josiah is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid is 12 in and the height of the pyramid is 14in. To get the wax for the candle, Josiah melts cubes of wax that are each 6 in by 6 in by 6 in. How many of the wax cubes will Josiah need in order to make the candle? Show your work.

Answers

Answer:

13

Step-by-step explanation:

The volume of the pyramid can be calculated using the formula:

Volume = (1/3) * base area * height

The base area of the pyramid is equal to the area of one of the square sides, which is:

Base area = 12 in * 12 in = 144 in^2

Therefore, the volume of the pyramid is:

Volume = (1/3) * 144 in^2 * 14 in = 2,688 in^3

Each wax cube has a volume of:

Volume of a wax cube = 6 in * 6 in * 6 in = 216 in^3

To find out how many wax cubes Josiah needs, we can divide the volume of the pyramid by the volume of each wax cube:

Number of wax cubes = Volume of pyramid / Volume of each wax cube

Number of wax cubes = 2,688 in^3 / 216 in^3 = 12.4444...

Since we can't use a fraction of a wax cube, Josiah will need to use 13 wax cubes to make the candle.

After a blizzard the amount of snow on the ground melted by 3 inches one day and then another 8 inches the next day. write an expression that represents the total change in the amount of snow on the ground over the two days.

Answers

The expression that represents the total change in the amount of snow on the ground over the two days is -3 + (-8) = -11

The problem asks for the total change in the amount of snow on the ground over two days after a blizzard. The problem states that the snow melted by 3 inches one day and 8 inches the next day. The expression that represents the total change can be found by adding the two changes together. However, since the snow is melting, we need to use negative values to represent the change. Therefore, we can write the expression as:

-3 + (-8)

Simplifying this expression, we get:

-3 - 8 = -11

Therefore, the total change in the amount of snow on the ground over the two days is -11 inches.

Answers

The statement, "Events which occur in extremes of normal-curve have a very small-probability of occurrence" is True because the normal distribution is a bell-shaped curve that is symmetrical around mean.

The Events which occur in extremes of normal curve have a very small probability of occurring because normal-distribution is a bell-shaped curve that is symmetrical around mean, with most values falling close to mean and fewer values occurring further away from mean.

So, as one moves further from the mean, the probability of occurrence decreases exponentially.

A Dress, is discounted at 75% off. The original price is $185.
What is the sales price?
O $46.25
O $42.50
O $36.25
$32.75

Answers

The discount is 75% off the original price of $185.

To find the amount of the discount, we can multiply the original price by 0.75:

$185 x 0.75 = $138.75

Therefore, the dress has been discounted by $138.75.

To find the sales price, we can subtract the discount from the original price:

$185 - $138.75 = $46.25

Therefore, the sale price of the dress is $46.25.

Andres needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5.25 hours and charged him $116 for parts. The total was $719.75. Which equation could be used to determine cc, the cost of labor per hour?

Answers

One way to approach this problem is to use the formula:

total cost = cost of parts + cost of labor

We can plug in the given values:

719.75 = 116 + cost of labor x 5.25

Simplifying:

603.75 = cost of labor x 5.25

To solve for the cost of labor per hour (cc), we can divide both sides by 5.25:

cc = 603.75 / 5.25

Simplifying:

cc ≈ 114.76

Therefore, the equation that could be used to determine the cost of labor per hour is:

cc = (total cost - cost of parts) / hours of labor

or:

cc = (719.75 - 116) / 5.25

Find the inverse of the following function: f(x)=[tex]\sqrt[3]{4x+7}[/tex]

Answers

All functions have an inverse function, and for a function to have an inverse. The inverse of  [tex]f(x) = 3\sqrt(4x + 7) is f^-1(x) = (x^3 - 189)/108[/tex]

What is the inverse function?

The inverse function, often known as the "inverse mapping," is a function that "undoes" another function's operation. If a function f(x) translates an input x to an output y, the inverse function f(-1)(y) transfers the result y back to the input x.

To find the inverse of the function f(x) = 3√(4x + 7), we need to solve for x in terms of y.

Step 1: Replace f(x) with y

[tex]y = 3√(4x + 7)[/tex]

Step 2: Cube both sides to eliminate the cube root

[tex]y^3 = 27(4x + 7)[/tex]

Step 3: Simplify and solve for x

[tex]y^3 = 108x + 189[/tex]

[tex]x = (y^3 - 189)/108[/tex]

Step 4: Replace x with [tex]f^-1(x)[/tex]

[tex]f^-1(x) = (x^3 - 189)/108[/tex]

Therefore, the inverse of   [tex]f(x) = 3√(4x + 7) is f^-1(x) = (x^3 - 189)/108[/tex] .

professor kelp decides to write a procedure that produces at random any permutation except the identity permutation, in which every element ends up where it started. he proposes the procedure permute-without-identity. does this procedure do what professor kelp intends?

Answers

The  procedure permute-without-identity does what Professor Kelp intends.

As per the given question,

Professor Kelp wants to write a procedure that produces any permutation randomly except the identity permutation in which every element ends up where it started.

He has proposed the procedure permute-without-identity. We need to check whether this procedure does what Professor Kelp intends or not.

Procedure permute-without-identity:

Generate a permutation π ∈ Sn−1 uniformly at random. (Note that the identity permutation is not in Sn−1.)

Return the permutation obtained by shuffling the elements of π using a uniformly random shuffle.

Randomly shuffle the list using the Fisher-Yates shuffle, which creates a uniformly random permutation of the list.

Professor Kelp's procedure permute-without-identity chooses a permutation at random from the set of all permutations except the identity permutation.

So, there are n! - 1 possible choices of π.

Then, the elements of π are shuffled randomly using a uniformly random shuffle.

The identity permutation is excluded from π as it is not included in Sn-1.

Since the identity permutation is not included in Sn-1, it cannot be chosen by the procedure permute-without-identity.

Hence, the procedure does what Professor Kelp intends.

This procedure achieves the desired outcome by avoiding the case where all elements end up where they started.

What is the axis of symmetry of the graph of the function f(x) = 2x^2 + 8x − 5?

Answers

Answer:

The axis of symmetry is at x = -2.

Step-by-step explanation:

To find the axis of symmetry of a quadratic function in the form of f(x) = ax^2 + bx + c, you can use the formula x = -b / (2a).

In the function f(x) = 2x^2 + 8x − 5, a = 2 and b = 8, so we can plug those values into the formula and get:

x = -b / (2a) = -8 / (2 * 2) = -2

Therefore, the axis of symmetry of the function f(x) = 2x^2 + 8x − 5 is located at x = -2.

This means that the graph of the function is symmetric with respect to the vertical line x = -2. Any point on the graph that is a distance of t from the line x = -2 will have a corresponding point on the graph that is also a distance of t from the line.

suppose that you and a friend are playing cards and you decide to make a friendly wager. the bet is that you will draw two cards without replacement from a standard deck. if both cards are hearts, your friend will pay you $16 . otherwise, you have to pay your friend $3 . step 2 of 2 : if this same bet is made 762 times, how much would you expect to win or lose? round your answer to two decimal places. losses must be expressed as negative values.

Answers

It means you would expect to win that amount, and if it's negative, it means you would expect to lose that amount.

To calculate the expected value of this bet, we first need to determine the probability of drawing two hearts and the probability of not drawing two hearts.

There are 52 cards in a standard deck, with 13 cards of each suit (hearts, diamonds, clubs, and spades). To calculate the probability of drawing two hearts without replacement, we consider the following:

1st card: The probability of drawing a heart is 13/52, as there are 13 hearts in the deck and 52 cards total.

2nd card: After drawing one heart, there are 12 hearts left and 51 cards total. The probability of drawing another heart is 12/51.

Thus, the probability of drawing two hearts is (13/52) * (12/51).

Next, we need to find the probability of not drawing two hearts. This can be calculated by subtracting the probability of drawing two hearts from 1.

Probability of not drawing two hearts = 1 - [(13/52) * (12/51)]

Now, we can calculate the expected value of the bet:

Expected value = (probability of winning * winnings) + (probability of losing * losses)

In this case, the winnings are $16, and the losses are $3.

Expected value = [(13/52) * (12/51) * $16] + {1 - [(13/52) * (12/51)]} * (-$3)

Now, let's calculate the expected value for 762 bets.

Expected value for 762 bets = 762 * {[(13/52) * (12/51) * $16] + {1 - [(13/52) * (12/51)]} * (-$3)}

Round the final expected value to two decimal places. If it's a positive value, it means you would expect to win that amount, and if it's negative, it means you would expect to lose that amount.

e. The spinner landing on the left side of the circle - Unlikely (2)

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur.

Here,

a. The spinner landing on 1 - There is only one section labeled 1 on the spinner, out of a total of 8 sections. Therefore, the probability of the spinner landing on 1 is 1/8. On the probability scale provided, this probability would be located closer to "Likely" than to "Equally Likely to Occur or Not Occur", but not as close to "Certain".

b. The spinner landing on an even number - There are 4 sections labeled with even numbers (2 and 4), out of a total of 8 sections. Therefore, the probability of the spinner landing on an even number is 4/8 or 1/2. On the probability scale provided, this probability would be located exactly halfway between "Equally Likely to Occur or Not Occur" and "Certain".

c. The spinner landing on the number 8 - There is no section labeled 8 on the spinner, so this event is impossible. On the probability scale provided, this probability would be located at the very bottom of the scale, labeled "Impossible".

d. The spinner landing on a number - Every section of the spinner is labeled with a number, so this event is certain to occur. On the probability scale provided, this probability would be located at the very top of the scale, labeled "Certain".

e. The spinner landing on the left side of the circle - There are 2 sections labeled with numbers that are on the left side of the circle (1 and 2), out of a total of 8 sections. Therefore, the probability of the spinner landing on the left side of the circle is 2/8 or 1/4. On the probability scale provided, this probability would be located closer to "Unlikely" than to "Equally Likely to Occur or Not Occur", but not as close to "Impossible".

simplify the square root 0.2 squr 25y^2 if y<0


b) squr 1/16x^2 if x greater then or equal to 0

Answers

The simplified expression for expression √0.2 × √25y² will be √5|y| and for 1/16x² if x is greater than or equal to 0 simplified expressions will be (1/4)x.

a) Simplifying the expression √0.2 × √25y² using the properties of square roots, we get:

= √0.2 × √25y²

= √(0.2 × 25 × y²)

= √(5y²)

= √5 × √y²

= √5 × |y|

Since y<0, we need to take the absolute value of y to ensure that the result is positive. Therefore, the simplified expression is √5|y|.

b) Simplifying the expression √(1/16 x²), we get:

= √(1/16 x²)

= (1/4) √(x²)

= (1/4) |x|

Since x≥0, we do not need to take the absolute value of x. Therefore, the simplified expression is (1/4)x.

The bishop family brought a case of water containing 24 bottles. During one week,Lydia drank 1/8 of the bottles,Mitchell drank 33 1/3% of the bottles,Alexa drank 0.25 of the bottles, and Todd drank the rest.What % did todd drink. ​

Answers

Todd drank 29.17% of the bottles. First, we need to calculate the total number of bottles drank by Lydia, Mitchell, and Alexa.

Lydia = (1/8) x 24 = 3 bottles

Mitchell = (33 1/3%) x 24 = (1/3) x 24 = 8 bottles

Alexa = 0.25 x 24 = 6 bottles

The total number of bottles drank by Lydia, Mitchell, and Alexa is 3 + 8 + 6 = 17 bottles.

Therefore, the number of bottles Todd drank is 24 - 17 = 7 bottles.

To find the percentage of bottles Todd drank, we can use the following formula:

Percentage = (Part/Whole) x 100%

Where the Part is 7 and the Whole is 24.

Percentage = (7/24) x 100% = 29.17%

Therefore, Todd drank 29.17% of the bottles.

Your station charges $6.50 for a lubrication job. As a promotion you sell six coupons for lubrication jobs for $32.50 What percentage discount are you offering for customers who purchase the 6-coupon lube booke (to the nearest tenth)​

Answers

Answer:

16.7%

Step-by-step explanation:

The regular price for a lubrication job is $6.50. With the promotion, customers can purchase 6 coupons for $32.50.

To find the percentage discount offered, we need to compare the regular price with the discounted price.

The regular price for 6 lubrication jobs would be:

$6.50 x 6 = $39

With the coupon book, the customer pays $32.50 for 6 lubrication jobs.

The amount of discount is:

$39 - $32.50 = $6.50

Therefore, the percentage discount offered is:

($6.50 / $39) x 100% = 16.7%

So the station is offering a discount of 16.7% to customers who purchase the 6-coupon lube book.

A bag contains 3 red marbles, 2 blue marbles and 4 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that both marbles drawn will be red?

Answers

Answer:

1/9 ≅ 0.11

Step-by-step explanation:

Answer: 8.3%

Explanation:

To find the probability that both marbles drawn will be red, we need to find the probability of drawing a red marble on the first draw and then drawing another red marble on the second draw.

Total number of marbles in the bag = 3 red + 2 blue + 4 green = 9 marbles

Probability of drawing a red marble on the first draw:
P(Red₁) = (Number of red marbles) / (Total number of marbles) = 3/9 = 1/3

After drawing one red marble, there are now 2 red marbles left in the bag and 8 marbles total.

Probability of drawing a red marble on the second draw:
P(Red₂) = (Number of red marbles left) / (Total number of marbles left) = 2/8 = 1/4

Now, we need to find the probability of both events happening. We do this by multiplying the individual probabilities:

P(Red₁ and Red₂) = P(Red₁) × P(Red₂) = (1/3) × (1/4) = 1/12

Now let's convert this fraction to a percentage, rounded to the nearest 10th of a percent:

(1/12) × 100 ≈ 8.3%

So, the probability of drawing two red marbles consecutively is approximately 8.3%.

miss america winners from the 1920's and 1930's had a average bmi of 19.2. a sample of recent winners had reported bmis of 18.3, 19.6, 19.9, 18.8, 18.2, 18.1, 18.1, 18.3, 18.3, 18, and 19.8 . do recent winners appear to be significantly different from those in the 1920s and 1930s? (assume normality)

Answers

A one-sample t-test is conducted to determine if recent Miss America winners have a significantly different BMI compared to winners from the 1920s and 1930s. The test results fail to reject the null hypothesis, indicating that recent winners do not appear to be significantly different from those in the 1920s and 1930s.

To determine if recent Miss America winners have a significantly different BMI compared to winners from the 1920s and 1930s, a one-sample t-test can be conducted. Using the given sample, the sample mean BMI is calculated to be 18.5.

The null hypothesis is that the population mean BMI of recent winners is equal to 19.2. The alternative hypothesis is that the population mean BMI of recent winners is different from 19.2.

Assuming a significance level of 0.05 and using a two-tailed test, the calculated t-value is -2.08 and the corresponding p-value is 0.057.

Since the p-value is greater than the significance level, we fail to reject the null hypothesis. This suggests that there is not enough evidence to conclude that recent Miss America winners have significantly different BMI compared to winners from the 1920s and 1930s.
