If r = 9, b = 5, and g= −6, what does (r + b − g)(b + g) equal?

Answers

Answer 1
Answer:

Answer:

-20

Step-by-step explanation:

(r + b − g)(b + g)

we have fom statement:

r = 9    

b = 5

g= −6

so we have:

(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))

(r + b − g)(b + g)= (14+6)*(-1)

(r + b − g)(b + g)= -20

What is the median of this data? 48, 60, 22, 84, 36

Answers

He is wrong. You first need to put it in order before getting the middle. Like so:
22, 36, 48, 60, 84
Now cross out 22, then 84, and so on till you're left with one number (the middle number)

THE ANSWER IS 48
22 because the median is just the middle number of a set of data
