Answer:

$c=17$ ft

Step-by-step explanation:

Base=b=8 ft

Hyp=c=?

Perp=a=15 ft

Applying Pythagoras theorem

$c=\sqrt{a^{2} + b^{2} }$

$c=\sqrt{15^{2} + 8^{2} }$

$c=\sqrt{289 }\\c=17$

For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two-tail

bagirrra123 [75]

Answer:

Option B:

$H_0: \mu = 22.1$

$H_a: \mu \neq 22.1$

Classification:

The hypothesis test is Two-tailed.

Step-by-step explanation:

The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.

This means that the null hypothesis is that the mean is of 22.1 months, that is:

$H_0: \mu = 22.1$

A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.

At the alternate hypothesis, we test if this mean is different of 22.1, that is:

$H_a: \mu \neq 22.1$

Which means that the answer is given by option b).

Which of the following is the correct classification of the hypothesis test?

We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.

2y+7 ÷ -4y - 10 Evaluate the expression below when y = -3

Nina [5.8K]

2y+7÷-4y-10
2(-3)+7÷-4(-3)-10
-6+7÷12-10
$\frac{7}{12}$ -6-10
$\frac{7}{12} -16
= \frac{7}{12} - \frac{192}{12} 
=- \frac{185}{12} 
=-15 \frac{5}{12}$
