gayaneshka [121]

Answer:

Hello! answer: 5

Step-by-step explanation:

What you do to find the answer for these is do a^2+b^2=c^2 Basically meaning 4 × 4 + 3 × 3 will equal a number that you then find the suare root of square root just meaning a number multiplied by itself to equals that number so...

4 × 4 = 16

3 × 3 = 9

16 + 9 = 25

√25 = 5

5 × 5 = 25 therefore c = 5 hope that helps!

An automobile manufacturer claims that its car has a 35.935.9 miles/gallon (MPG) rating. An independent testing firm has been co
Serjik [45]
<h2>Answer with explanation:</h2>

Let \mu be the population mean.

For the given claim , we have

Null hypothesis : H_0: \mu=35.9

Alternative hypothesis :  H_a: \mu\neq35.9

Since alternative hypothesis is two-tailed , so the test is a two-tailed test.

Given : Sample size : n=220  ;

Sample mean: \overline{x}=35.6  ;

Standard deviation: s=2.2

Test statistic for population mean:

z=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

z=\dfrac{35.6-35.9}{\dfrac{2.2}{\sqrt{220}}}\approx-2.02

By using the standard normal distribution table of z , we have

P-value ( two tailed test ) : 2P(Z>|z|)=2(1-P(Z

=2(1-P(z

Since , the P-value is greater than the significance level of \alpha=0.02 , it means we do not have sufficient evidence to reject the null hypothesis.
