Answer:

D. 15

Step-by-step explanation:

Given the expression, 32 + 2n - 9, and a value of <em>n </em>= -4:

You can substitute the value of <em>n</em> into the given expression:

= 32 + 2n - 9

= 32 + 2(-4) - 9

= 32 - 8 - 9

= 15

Therefore, the correct answer is D. 15

This graph shows a portion of an odd function.
damaskus [11]

Answer:

f(x) =

-2

-1

-2

-3

On Edgenuity 2020

Step-by-step explanation:

Got it correct on Edgenuity :)

Or if you would like the longer explanation;

The graph given explained:

On a coordinate plane, a function has four connecting lines. The first line goes from (0, 0) to (2,2), the second line goes from (2, 2) to (3, 1), the third line goes from (3, 1) to (5, 3), and the fourth line is horizontal to the x-axis at 3.

After finding the matching points on the graph using the coordinates on the x axis (on the line), you should get 2, 1, 2, and 3. Then use the odd function which is

f(-x) = -f(x) and insert those numbers in -f(x)

which leads you to the answer above which is

f(x) =

-2

-1

-2

-3

Hopefully this helped !

Sorry I couldn't explain it any better but I did it in a way that I was able to understand how I got my answer ! :)

Create a data set of 15 numbers where the mean and median are both 59 and the standard deviation is between 10 and 11. Then, add
Ann [662]

What we should do is create a set of 15 data.

To comply with the mean and median 59, what we will do is make our center point 59, we will add 7 values ​​backwards and 7 values ​​forward, always the same value adding in the case forward or subtracting in the case of backwards the same number so that the mean is not affected

So:

We will add 2.5 in the same proportion, we start with the forward ones:

59 + 2.5 * 1 = 61.5

59 + 2.5 * 2 = 64

59 + 2.5 * 3 = 66.5

59 + 2.5 * 4 = 69

59 + 2.5 * 5 = 71.5

59 + 2.5 * 6 = 74

59 + 2.5 * 7 = 76.5

Backward:

59 - 2.5 * 7 = 41.5

59 - 2.5 * 6 = 44

59 - 2.5 * 5 = 46.5

59 - 2.5 * 4 = 49

59 - 2.5 * 3 = 51.5

59 - 2.5 * 2 = 254

59 - 2.5 * 1 = 56.5

Therefore, the entire data set would be:

41.5, 44, 46.5, 49, 51.5, 54, 56.5, 59, 61.5, 64, 66.5, 69, 71.5, 74, 76.5

We guarantee the mean and median 59.

The standard deviation is equal to 10.8

Now if we change the first value of 41.5 by 1000, we will see what happens:

New dataset:

1000, 44, 46.5, 49, 51.5, 54, 56.5, 59, 61.5, 64, 66.5, 69, 71.5, 74, 76.5

The mean changes to 122.9

And the standard deviation to 234.62

In other words, there is a significant increase in the mean, but in the standard deviation the growth is abysmal.

I attach an excel to check all this data.

Mr.Endo buys 13.6 gallons of gasoline. He pays $3.95 per gallon. How much does Mr.Endo spend on gasoline
makkiz [27]

Cost per gallon of gasoline = $3.95 per gallon.

Total number of gallons of gasoline Mr.Endo buys = 13.6 gallons.

We need to find the total cost of 13.6 gallons of gasoline.

<em>In order to find the total cost of 13.6 gallons of gasoline, we need to multiply it by cost of each gallon of gasoline.</em>

Therefore, cost of 13.6 gallons of gasoline = 13.6 × 3.95

On multiplying 13.6 by 3.95, we get 53.72.

<h3>Therefore, Mr.Endo spend a total $ 53.72 on gasoline.</h3>
