Answer:

C. x - y = 0

Step-by-step explanation:

Step 1: find the slope (m) and y-intercept (b) of the graphed line.

Using the two points on the line (0, 0) and (2, 2),

Slope = [tex] \frac{rise}{run} = \frac{2 - 0}{2 - 0} = \frac{2}{2} = 1 [/tex]

The y-intercept (b) is the point at which the line intercepts the y-axis. Therefore, the y-intercept (b) = 0

Step 2: Generate an equation for the line in slope-intercept form using b = 0 and m = 1.

Substitute m = 1 and b = 0 into y = mx + b

y = 1(x) + 0

y = x

Step 3: rewrite the equation from slope-intercept form to standard form.

To express I'm standard form, take all terms with coefficient to the left, and leave the constant on the right side of the equation.

y = x

Subtract y from both sides

y - y = x - y

0 = x - y

x - y = 0

Answer:

8.5 minutes

Step-by-step explanation:

the bottle will have leaked half into the 2nd bottle, meaning the 2nd bottle has half too

It will take 17 minutes for the two bottles to have the same amount of water.

Something calculated for one is called unit rate.

Given that, A full 17 oz bottle of spring water is leaking half of an ounce a minute into an empty bottle.

To have same amount of water both the bottles will have 17/2 = 8.5 ounces of water in them,

Since, it takes a minute to leak or fill half of an ounce,

Therefore, one ounce will take 2 minutes.

Therefore, 8.5 ounces will take = 8.5×2 = 17

Hence, it will take 17 minutes for the two bottles to have the same amount of water.

Answer:

[tex]b=-3[/tex]

Step-by-step explanation:

We have:

[tex]25^b\cdot 125^{b+2}=125^b[/tex]

Notice that 125 is the same as 5³. So:

[tex]25^b\cdot ((5)^3)^{b+2}=((5)^3)^b[/tex]

Also, 25 is the same as 5². So:

[tex]((5)^2)^b\cdot ((5)^3)^{b+2}=((5)^3)^b[/tex]

Power of a power property:

[tex]5^{2b}\cdot 5^{3(b+2)}=5^{3b}[/tex]

Power of a product property:

[tex]5^{2b+3(b+2)}=5^{3b}[/tex]

Since they have the same base, the exponents are equal. So:

[tex]2b+3(b+2)=3b[/tex]

Solve for b. Distribute on the left:

[tex]2b+3b+6=3b[/tex]

Combine like terms on the left:

[tex]5b+6=3b[/tex]

Subtract 5b from both sides:

[tex]6=-2b[/tex]

Divide both sides by -2. So, the value of b is:

[tex]b=-3[/tex]

And we're done!

Answer:

Step-by-step explanation:

Pat believes that [tex]\sqrt{2}+\sqrt{8}=(2)(2)^{\frac{1}{2}}[/tex]

[tex]\sqrt{2}+\sqrt{8}=\sqrt{2}+\sqrt{4\times 2}[/tex]

             [tex]=\sqrt{2}+2\sqrt{2}[/tex]

             [tex]=3\sqrt{2}[/tex]

             [tex]=3(2)^{\frac{1}{2} }[/tex]

But [tex]2(2)^{\frac{1}{2}}\neq 3(2)^{\frac{1}{2}}[/tex]

Therefore, Pat's belief is not correct.

Camilla believes that [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex]

Which is correct as we have calculated above.

Therefore, [tex]\sqrt{2}+\sqrt{8}=3\sqrt{2}[/tex] will be the correct answer.

Answer:

1. 43, 45, and 47

2. 50, 52, and 54

3. 47 years old

4. 106 degrees

5. 66 degrees

Step-by-step explanation:

1. Let's assume that the first number in the three consecutive odd numbers is x.

We can write an equation to express this now. [tex]x + (x+2) = (x+4) + 41[/tex].

Combining like terms, we get [tex]2x+2 = x+45[/tex]. Subtracting by (x+2) on each side, we get [tex]x = 43[/tex]. Since the smallest number is 43, we can find the two larger numbers as well, since they are 2 more than one another. Therefore, the numbers are 43, 45, and 47.

2. Let's assume that the first number in the three consecutive even integers is x.

We can write an equation to express this now. [tex]x + (x+2) = (x+4)+48[/tex]

Combining like terms, we get [tex]2x+2 = x+52[/tex]. Subtracting by (x+2) on each side, we get [tex]x = 50[/tex]. Since the smallest number is 50, we can find the two larger numbers as well, since they are 2 more than one another. Therefore, the numbers are 50, 52, and 54

3. We can write his current age in years as x. Next year, his age will be x+1. We know that the sum of his current age and his age next year is 73, so we can write an equation to express this.

[tex]x + (x+1) = 73[/tex]. Therefore, 2x + 1 = 73, or 2x = 72. This means that x = 36, or his current age is 36. In 11 years, his age will be 36 + 11 = 47 years old.

4. [tex](21x+1) + (14x+4) = 180[/tex]. Combining like terms, we get [tex]35x + 5 = 180[/tex] Subtracting by 5 on both sides, we get [tex]35x = 175[/tex] This means that [tex]x = 5[/tex]. Now, we can find the degree measures of both angles and find the larger one. The degree measure of the angle on the left is 21(5) + 1 = 106 degrees, and the degree measure of the angle on the right is 14(5) + 4 = 74 degrees. Therefore, the degree measure of the larger angle is 106 degrees.

5. We know that the sum of the angles in a triangle is 180 degrees. Therefore, we can sum the angles up and equate them to 180 degrees.

(x-24) + (2x-108) + (1/3x+12) = 10/3x - 120 = 180. Adding 120 to both sides, we get 10/3x = 300. Multiplying both sides by 3/10, we get x = 900/10 = 90. Therefore, plugging in x = 90, we get 66 degrees.

Answer:

a) Mean is 12.9

b) Standard Error

i) n = 16, Standard Error = 1

The shape of the sampling distribution means is not normal

ii) n = 49 , Standard Error = 0.5714285714

The shape of the sampling distribution means is normal

iii) n = 121, Standard Error = 0.3636363636

The shape of the sampling distribution means is normal

c)Describe the pattern as n increases

As the number of random samples(n) increases the value for the standard error decreases

Step-by-step explanation:

Central Limit Theorem states that

if the sample size is large (generally n ≥ 30), and the standard deviation of the population is finite, then the distribution of sample means will be approximately normal.

a) 16 residents

Mean = 12.9

Standard Error = Standard Deviation /√n

= 4/√16

= 4/4

= 1

n < 30, hence, The shape of the sampling distribution means is not normal

b) 49 residents

= Mean = 12.9

Standard Error = Standard Deviation /√n

= 4/√49

= 4/7

= 0.5714285714

n > 30, hence, The shape of the sampling distribution means is normal

c) 121 residents

Mean = 12.9

Standard Error = Standard Deviation /√n

= 4/√121

= 4/11

= 0.3636363636

n > 30, hence, The shape of the sampling distribution means is normal

Describe the pattern as n increases

As the number of random samples(n) increases the value for the standard error decreases

Answer:

it will be shrunk by a factor of 0.8

Step-by-step explanation:

i just got it right

The parent absolute value function will be contract by factor 0.8.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.

We have,

f(x) = 0.8 |x|

We know the 0.8 represent the scale factor which leads to dilation.

As, 0.8 < 1 then it means that the figure is going to be contract or smaller than original figure.

Thus, the Function will be contract by factor 0.8

The "ratio of shirts to skirts" means "the number of shirts divided by number of skirts."

10 shirts

15 skirts

shirts : skirts = 10/15 = 2/3

Answer: 2/3

(b)

In the simplified ratio, there are 2 shirts for every 3 skirts.

Add 2 + 3 = 5.

The ratio of skirts to total number of items of clothing is 3:5.

There are 3 skirts to each 5 items of clothing.

Set up a proportion.

Answer:

35 days

Step-by-step explanation:

Andrew brings juice for lunch every 5 days and Hannah brings juice every 7 days

Find the lowest common multiple of 5 and 7

Andrew (every 5 days) = 10, 15, 20, 25, 30, 35, 40, 45, 50

Hannah (every 7 days) = 14, 21, 28, 35, 42, 49, 56

The lowest common multiple of 5 and 7 is 35

Therefore, if Andrew and Hannah both brought juice today, it will take 35 days before they will both bring food again on the same day.

Answer:

Step-by-step explanation:

In 50 times Juan will jump 40 times.

Unitary method is first finding the value of a single unit and then deriving the required units from the given data.

For example - : A can eat 2 bananas in 2 seconds.So he can eat one banana in 1 second.From this we can calculate how many bananas he can eat in any given time.

According to the given question Juan jumped 24 times in 30 seconds.

∴ In 1 sec Juan will jump 24/30 times which is

= 4/5 times.

So, in 50 secs Juan will jump ( 4/5 × 50 ) = 40 times.
