Find the sum. express your answer in the simplest form

-11p^2  -10

q+8  

Step-by-step explanation:

-7p^2 -7          -4p^2 -3

+  

q+8                       q+8

Since the denominators are the same, we can add like terms in the numerators

-7p^2  -4p^2  -7-3

q+8                  

-11p^2  -10

q+8      

the answer is 4 out of 10 or 4/10 = 0.4

Step-by-step explanation:

from the question which says that the  ages of five randomly chosen cars in a parking garage are determined to be 7, 9, 3, 4, and 6 years old. If one considers this sample of 5 in groups of 3

solution

the number of groups of 3 that are possible implies that

5 choose 3 = 10 possible groups of 3

also,

the number of these groups of 3 that have a true mean of more than 6years needs to be considered.

The following groups add up to 19 or more ; (9,7,6), (9,7,4), ( 9,7,3) , (9,7,4).

therefore the answer is 4 out of 10 or 4/10 = 0.4
