A right triangle has a hypotenuse length of 12, and one side length of 9. find the missing side length. do the side lengths form
Rina8888 [55]

Use the Pythagorean theorem:

a^2+b^2=c^2

c - a hypotenuse

a, b - legs

We have: a = 9 and c = 12. Substitute:

9^2+b^2=12^2

81+b^2=144               <em>subtract 81 from both sides</em>

b^2=63\to b=\sqrt{63}\\\\b=\sqrt{9\cdot7}\\\\b=\sqrt9\cdot\sqrt7\\\\ \boxed{b=3\sqrt{7}}

A Pythagorean triple consists of three positive integers a, b and c, such that

a^2+b^2=c^2.

b=3\sqrt{7} is not positive integer.

<h3>The sides of the triangle do not form a pythagorean triple.</h3>

Administrators at a large public high school are interested in their students’ standardized test scores. Last year, the mean sco
ratelena [41]

Answer:

The appropriate hypotheses for performing a significance test is:

H_0: \mu = 51

H_1: \mu > 51

Step-by-step explanation:

Last year, the mean score on the state’s math test was 51. The administrators have trained the teachers in a new method of teaching math hoping to raise the scores on this standardized test this year.

At the null hypothesis, we test if the mean score this year is the same as last year, that is:

H_0: \mu = 51

At the alternate hypothesis, we test if the mean score improved this year from last, that is:

H_1: \mu > 51

The appropriate hypotheses for performing a significance test is:

H_0: \mu = 51

H_1: \mu > 51
