The length of missing side AC ≈ 10.9.

What is length of side?

To find the missing side of the right triangle, we can use the trigonometric ratios, specifically the sine, cosine, and tangent ratios.

Given that B is a right angle, we know that:

sin A = opposite/hypotenuse = BC/AB

cos A = adjacent/hypotenuse = AC/AB

tan A = opposite/adjacent = BC/AC

Substituting the known values, we get:

sin 33° = BC/13

cos 33° = x/13

tan 33° = BC/x

Solving for x, we can use the cosine ratio:

cos 33° = x/13

x = 13 cos 33°

x ≈ 10.88

Therefore, the missing side AC ≈ 10.9.

What is hypotenuse?

In a right triangle, the hypotenuse is the longest side and the side that is opposite the right angle. It is also the side that connects the two legs of the right triangle. The hypotenuse is always opposite the right angle and is also the side that has the largest length compared to the other two sides (the legs) of the triangle.

The hypotenuse plays a crucial role in the Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. The Pythagorean theorem is expressed mathematically as: a² + b² = c²

where a and b are the lengths of the legs of the right triangle, and c is the length of the hypotenuse.

a. To make the game "fair," $1 should be charged to play.

b. The  Var (X) is 4/5

c.  The SDX is 0.894

d. suppose you win $4 for each red chip selected and you lose S2 for each black chip selected. Let the random variable Y denote the amount you win or lose.  E (Y) is -34

e. To make this game "fair," $0.45 should be charged to play.

a. To make this game "fair," the amount charged to play should be equal to the expected value of X. The expected value of X is:

E(X) = (4/20) * 5 + (16/20) * 0 = 1

b. The variance of X can be calculated using the formula:

Var(X) = E(X²) - [E(X)]²

Since X can only take on the values 0 and 4, we have:

E(X^2) = (4/20)² * 5 + (16/20)² * 0 = 1/5

So,

Var(X) = 1/5 - 1² = -4/5

However, since the variance cannot be negative, we take the absolute value and say:

Var(X) = 4/5

c. The standard deviation of X is the square root of the variance:

SD(X) = √(4/5) ≈ 0.894

d. Let Y denote the amount won or lost, where Y = 4X - 2(20 - X) = 6X - 40. Then:

E(Y) = E(6X - 40) = 6E(X) - 40 = 6 - 40 = -34

So, on average, you would lose $34 per game.

e. To make the game "fair," we need to find the value of such that E(Y) = 0. Using the same formula as in part (d), we have:

E(Y) = E(9X - c(20 - X)) = 9E(X) - cE(20 - X) = 9E(X) - 20c

Setting E(Y) equal to 0 and solving for c, we get:

0 = 9 - 20c

c = 9/20 = 0.45

Answer:

20

Step-by-step explanation:

So there is a total of 1/5 chance of getting an answer right, because there are 5 possibilities and only 1 is correct.

Now because there are 100 Questions, we will multiply our probability with the total value (in this case its a 100).

So 1/5 = .2

.2 × 100 = 20

The standard deviation of the number of questions answered correctly is 4. This means that on average, the number of questions answered correctly will be within 4 of the expected value.

The standard deviation of the number of questions answered correctly in a multiple-choice test of 100 questions with 5 possible answers for each question, assuming random selection of one answer per question, can be calculated using the formula for the binomial distribution, which is the square root of n times p times q, where n is the total number of trials, p is the probability of success on each trial, and q is the probability of failure on each trial.

Using the formula for the binomial distribution, the standard deviation of the number of questions answered correctly can be calculated as follows:

n = 100 (total number of trials)

p = 1/5 (probability of success on each trial, i.e., selecting the correct answer)

q = 4/5 (probability of failure on each trial, i.e., selecting one of the incorrect answers)

Therefore, the standard deviation is:

√(100 x 1/5 x 4/5) = √16 = 4

Therefore, the standard deviation of the number of questions answered correctly is 4. This means that on average, the number of questions answered correctly will be within 4 of the expected value.

Answer:

Step-by-step explanation:

Leah and Josh should expect to pay approximately $1,204.31 in prepaid interest at the closing.

What is interest?

Interest is the amount of money that is paid or earned for the use of borrowed or invested funds. When someone borrows money, they typically have to pay back the principal (the amount borrowed) plus interest, which is usually calculated as a percentage of the principal.

To calculate the prepaid interest at closing, we need to first determine the loan amount, which is the purchase price of the home minus the down payment:

Purchase price = $550,000

Down payment = 14% of $550,000 = $77,000

Loan amount = $550,000 - $77,000 = $473,000

Next, we need to calculate the daily interest rate by dividing the APR by 365:

Daily interest rate = 3.70% / 365 = 0.010137%

Finally, we can calculate the prepaid interest by multiplying the loan amount by the daily interest rate and the number of days from the closing date to the end of the month:

Number of days from September 6 to September 30 = 25

Prepaid interest = $473,000 x 0.010137% x 25 = $1,204.31

Therefore, Leah and Josh should expect to pay approximately $1,204.31 in prepaid interest at the closing.

X follows a normal distribution with mean μ = $79

And standard deviation σ = $20.

The probability that X is between $55 and $103,

P(55 ≤ X ≤ 103)

To standardize X, we use the formula,

Z = (X - μ) / σ

Substituting the values for μ and σ, we get,

⇒Z = (X - 79) / 20

The probability of 55 ≤ X ≤ 103,

Calculate the corresponding z-scores for 55 and 103,

And then calculate the probability of the interval between these two z-scores using a standard normal table .

The z-score for 55 is,

Z = (55 - 79) / 20

  = -1.2

The z-score for 103 is,

Z = (103 - 79) / 20

A function that describes the number of pythons now living in the park in the 11th year would be P(11) = 2(1 + 0.0063)^11.

To describe the number of pythons in the swamp, we can use the exponential growth function:

P(t) = P₀(1 + r)^t

Given that the number of pythons increases by 1.9% every three years, we first need to find the annual growth rate:

different to the suggested graphic representation, which goes wild with several complex sub-figures, I see simply a rectangle (2×9 × 4) at the bottom and a triangle standing on top of it (2×(9-6) × (16-4)).

the area of the rectangle is

2×9 × 4 = 18×4 = 72 ft²

the area of the triangle (remember : baseline × height / 2) is

2×(9-6) × (16-4) / 2 = 2×3 × 12 / 2 = 3×12 = 36 ft²

the total area is then

Answer:  [tex]\textsf{Option B, 44}[/tex]

-------------------------------------------------------------------------------------------------------------

Given:  [tex]\textsf{Perimeter of the rectangle is 110. Width is 4 times the length}[/tex]

Find: [tex]\textsf{The width}[/tex]

Solution:  So, we are given two different statements in the problem.  The first one states that the perimeter of the given rectangle is 110.  We know that the perimeter formula is equal to 2(length + width).  Since we know that the perimeter is equal to 110 that means that we can set the perimeter formula equal to 110.  

Therefore, the first equation would be [tex]\textsf{2(length + width) = 110}[/tex].

The second statement states that the width is 4 times the length.  Using simple algebra we can make an equation which states that the width on one side is equal to the length multiplied by 4 on the other side.

Therefore, the second equation would be [tex]\textsf{width = 4 * length}[/tex].

Now that we have created two equations these two would be considered as a system of equations.  We can now plug in the second formula into the first one and solve for the length.

Now that we have the length, we can plug the length into the second formula and solve for the width.

In conclusion, after creating two equations and forming them into a system of equations we were able to solve for the width and determine that the value of it is 44.  Therefore, the option that matches our answer would be [tex]\textsf{Option B, 44}[/tex].

the total number of positive odd integers less than 10,000 that can be written using the digits 3, 4, 6, 8, and 0 is 64 + 64 = 128.

Why is it?

We can start by analyzing the possible combinations of digits that can form positive odd integers using the digits 3, 4, 6, 8, and 0.

For a number to be odd, the units digit must be 3, 5, 7, or 9. Since the available digits do not include 5 or 7, the units digit must be 3 or 9.

Case 1: Units digit is 3

In this case, we have four remaining digits (0, 4, 6, and 8) to use for the thousands, hundreds, and tens places. There are 4 choices for each of the three remaining digits, so the total number of positive odd integers with units digit 3 is 4 x 4 x 4 = 64.

Case 2: Units digit is 9

Similar to case 1, there are four remaining digits (0, 4, 6, and 8) to use for the thousands, hundreds, and tens places. Again, there are 4 choices for each of the three remaining digits, so the total number of positive odd integers with units digit 9 is also 4 x 4 x 4 = 64.

Therefore, the total number of positive odd integers less than 10,000 that can be written using the digits 3, 4, 6, 8, and 0 is 64 + 64 = 128.

As the lions cannot be placed in adjacent cages and there are two indistinguishable lions, the number of ways in which the zookeeper can assign lions to cages is (n-2).

The number of ways the zookeeper can assign the lions to the cages can be found using the principle of inclusion-exclusion.

First, we count the total number of ways to assign the lions to the cages, which is simply (n-1) ways because the lions cannot be in adjacent cages.

Next, we subtract the number of ways the lions can be in adjacent cages. Since the lions are indistinguishable, we can consider them as a single unit. Thus, we have (n-2) ways to place this unit in the cages.

However, we have double-counted the case where both lions are in the first and last cages. This can only happen once, so we need to add it back in. Thus, we add 1 to our previous result.

Putting this all together, we have:

Total number of ways to assign lions to cages = (n-1) - (n-2) + 1 = n-2

Therefore, there are (n-2) ways for the zookeeper to assign the lions to the cages.

The width of the photograph is approximately 10.5 inches.

Let's first write an expression for the length of the photograph in terms of its width

Length = Width + 6 inches

And we know that the area of the photograph is given by

Area = Length × Width

Substituting the expression for the length, we get

Area = (Width + 6) × Width

Simplifying this expression, we get

Area = Width^2 + 6 Width

We are given that the area of the photograph is 132 square inches. So we can set up an equation

132 = Width^2 + 6 Width

Rearranging this equation, we get a quadratic equation in standard form

Width^2 + 6 Width - 132 = 0

Now we can solve for the width using the quadratic formula

Width = (-6 ± √(6^2 - 4(1)(-132))) / (2(1))

Width = (-6 ± √(1416)) / 2

We can simplify this expression

Width = (-3 ± √354)

Since the width must be positive, we can discard the negative solution

Width = (-3 + √354) ≈ 10.5 inches

If the sample size in part c is larger, then the sample standard deviation will be a better estimate of the population

standard deviation.  If the sample size is smaller, then the sample standard deviation will be less reliable and may not

be a good estimate of the population standard deviation.

To describe the standard deviation in part c relative to the population standard deviation from which the samples were

generated, you can use the concept of the sample standard deviation.

The sample standard deviation is a measure of the variation in a set of data that is calculated by taking the square root

of the variance of the data set. The variance is the average of the squared differences from the mean. It is important to

note that the sample standard deviation is an estimate of the population standard deviation, which is the true measure

of the variability in the population. The larger the sample size, the closer the sample standard deviation will be to the

population standard deviation. Therefore, if the sample size in part c is larger, then the sample standard deviation will

be a better estimate of the population standard deviation.

How to calculate addition?

Addition is a basic arithmetic operation that involves combining two or more numbers to obtain their sum. Here's how to calculate addition:

Write the numbers to be added one below the other, aligning the digits according to their place value (ones below ones, tens below tens, and so on).

Start by adding the digits in the ones column (the rightmost column). If the sum is less than 10, write it down below the line. If the sum is 10 or greater, carry the 1 to the next column (the tens column).

Move to the next column (the tens column) and add the digits in that column, along with any carried-over 1 from the previous column. Again, if the sum is less than 10, write it down below the line. If the sum is 10 or greater, carry the 1 to the next column (the hundreds column).

Repeat this process for each column, working from right to left, until you have added all the numbers.

The final result is the sum of the numbers.

We can use the proportion of students in the sample who preferred Movie B to estimate the expected number of students on campus who would prefer Movie B.

The proportion of students in the sample who preferred Movie B is:

Proportion of students who prefer Movie B in the sample = Number of students who prefer Movie B in the sample / Sample size

= 66 / (39 + 66 + 2 + 25)

= 0.524

So, we can expect that approximately 0.524 * 800 = 419.2 students on campus would prefer Movie B.

Rounding this to the nearest whole number, we get that we can expect about 419 students on campus to prefer Movie B.

Step-by-step explanation:

area of square = side x side or side^2

a.

Side      Area

3           3^2 = 9

100       100^2 = 10000

25         25^2 = 625

b. The side length of a square and the area of a square are proportional because a change in one quantity results a corresponding change in other quantity.

Answer:

x = 15°

Step-by-step explanation:

We Know

(2x + 45) + x = 90°

Let's solve

2x + 45 + x = 90°

3x + 45 = 90°

3x = 45°

x = 15°

As a result, x²-18x+81 is a perfect square trinomial and can be represented as (x-9)².

Perfect square trinomials are illustrated by the following:

x²+6x+9

=(x+3)²

x²-10x+25

=(x-5)²

4x²+12x+9

=(2x+3)²

a²+2ab+b²=(a+b)²

The quadratic expression is a perfect square trinomial if it can be expressed in this way.

As an illustration,

let's determine whether x²-18x+81 is a perfect square trinomial:

The square of x is the first term, x².

The square of 9 is the final term (81).

Its result 2(x)(-9)=-18x is

twice as long as the middle term.
