Solve for r.
-13 = r/9 +8

r = - 189

first:

-13 -8 = -21

add the two negative number together and get -21

second:

r/9 >> 9 * -21

multiply 9 and -21 together and get -189

r = -189

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
