most popular sizes. The most popular sizes are 6, 7, 8, 9, and 10. She also orders 3 pairs in size 5 and 3 pairs in size 11.
For every new style, how many pairs of shoes does she need to order in total?

She orders 5 pair in 5 different sizes:

5 x 5 = 25 pair

She orders 3 pair in 3 different sizes:

3 x 3 = 9 pair

Total pairs = 25 + 9 = 34 pair.

Complete the equation: x^2-14x + __ = (__)^2
slamgirl [31]

Answer:

C. 49, x-7

Step-by-step explanation:

(A+B)^2 = A^2 + 2AB + B^2

-14x = 2*A*B

where A=x

Therefore B=-7

and (x-7)^2=x^2-14x+49

Spaulding is the leading maker for basketballs in the US. Spaulding prides itself on the quality that its basketballs have the r
Vesna [10]

Answer:

0 < 0.05, which means that we reject the null hypothesis, meaning that the air pressure of the balls is different of the target value of 7.9.

Step-by-step explanation:

The air pressure of a particular ball has a target value of 7.9 PSI.

This means that the null hypothesis is:

H_{0}: \mu = 7.9

The alternate hypothesis is:

H_{a}: \mu \neq 7.9

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

The hypothesis tested means that \mu = 7.9

Suppose the basketballs have a normal distribution with a standard deviation of 0.20 PSI.

This means that \sigma = 0.2

When a shipment of basketballs arrive, the consumer takes a sample of 21 from the shipment and measures their PSI to see if it meets the target value, and finds the mean to be 7.3 PSI.

This means that X = 7.3, n = 21

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{7.3 - 7.9}{\frac{0.2}{\sqrt{21}}}

z = -13.74

pvalue:

We are testing that the mean pressure is different than the target value of 7.9, and since the test statistic is negative, the pvalue is 2 multiplied by the pvalue of z = -13.74, which we find looking at the z-table.

z = -13.74 has a pvalue of 0.

2*0 = 0

0 < 0.05, which means that we reject the null hypothesis, meaning that the air pressure of the balls is different of the target value of 7.9.
