Answer: Chi-square test
Step-by-step explanation:
A Chi-square test is a test used or applied to check or see if a relationship between two categorical variables. Example
The marketing firm trying to show their client that there is a linear relationship between sales and the amount of money the client has invested in radio advertisements uses chi-square method by comparing the two variables which are Sales made and Amount spent on advert or promotion on radio.
Here you are trying to find the hypotenuse. So you would take
5^2 (five squared) plus 12^2 (twelve squared) and add them using the equation a^2+b^2= c^2. Now you square 5 and 12 to get 25 and 144. You add them together and get 169. Take the square root of 169 and c. The square root on c will cancel out the squared (to the power of two) part leaving you with just c. And the square root of 169 is 13. So c (the missing length) is 13. C=13.
Answer:
13 inches
Step-by-step explanation:
legs are 5 inch and 12 inch
we have to find hypotenuse
use formula
a^2 + b^2 =c^2
here a and b are legs of a triangle and hypotenuse is c so,
5^2 + 12^2 =c^2
25 + 144 =c^2
169 =c^2
=c
13 =c
therefore hypotenuse is 13 inches.
