Answer:

x = 95°

y = 147°

z = 128°

Step-by-step explanation:

∡x is the sum of 50 and 45, deducted from 180

∡y = 95 + 52, deducted from 180

∡z = 180 - 52

Solve for x.
alexandr402 [8]

the answer would be x=1 because if u do the math u get 3/2 and that simplified is 1 so this how i got the answer not 100% sure though but thats what i got

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.

What is S7 for the arithmetic series: a1 = 26, d = 3, and a7 = 44
Vaselesa [24]

Answer:

The answer is 245

Step-by-step explanation:

For arithmetic series with n=7: S7=(a1+a7)*7/2

Thus, S7=(26+44)*7/2=245

The answer is 245
