Can anyone please help me with number 17?

sweet-ann [11.9K]

The answer is G. I know because, 1.75 * 3 (slices of pizza) = 5.25.

13.75 - 5.25 = 8.5

8.5 / 4 (hot dogs) = 2.1 (price per hot dog)

We can apply this to Sarah by saying

2 * 1.75 = 3.5

3 * 2.1 = 6.3

Added equals 9.8 or 9.75 (Sarah's total)

Correct me if I am wrong hope this helps:)

Solve the inequality:
6x > 300
÷6 ÷6
x > 50

Graph the inequality.
y = 6x

x is the number of pies sold; x at least 50 and gradually increases.

You previously found the mean of this data set. Use that in answering the question. 63, 89, 92, 73, 79, 72, 34, 36, 94, 21, 25,

Answer:

Sum of squares of differences = 11239.74

Step-by-step explanation:

We are given the following data set:

63, 89, 92, 73, 79, 72, 34, 36, 94, 21, 25, 93, 22, 90, 79

We have to calculate the sum of square of the data set.

Formula:

$\text{Sum of square of differences} = \sum (x_i -\bar{x})^2$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{962}{15} = 64.13$

Sum of squares of differences =

1.284444444 + 618.3511113 + 776.5511113 + 78.61777778 + 221.0177779 + 61.88444445 + 908.0177776 + 791.4844443 + 892.017778 + 1860.484444 + 1531.417778 + 833.2844446 + 1775.217777 + 669.0844446 + 221.0177779

= 11239.74
