Median =  middle number

Total ten numbers so 
median =   (17 + b)/2
given median = 18
so
(17 + b)/  2 = 18
17+b = 36
b = 36 - 17
b = 19

Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25

Mean =  (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24  +25)/ 10
Given mean = 17

so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24  +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9

answer
a = 9
b = 19

A store manager is accepting applications for part-time workers. he can hire no more than 14 people. so far,he has hired 9 peopl
Lorico [155]

The manager already hired 9 people. Let x be the number of people he still can hire. Since these people will add to the 9 he already hired, when the hiring campaign will be over he will have hired 9+x people. We know that he can't hire more than 14 people, so the number of people hired must be less than or equal to 14:

9+x \leq 14

If we subtract 9 from both sides, we have

x \leq 14-9=5

so, the manager can hire at most 5 other people

F(x) = -4x + 15 g(x) = 7x^3 Find (f-g)(2)
djyliett [7]

(f-g)(2)=f(2)-g(2)

Therefore, find f(2) and g(2) first before subtracting.

f(x)=-4x+15

Therefore,

f(2)=-4(2)+15\\f(2)=-8+15\\f(2)=7

Then find g(2)

g(x)=7x^3\\g(2)=7(2)^3\\g(2)=7(8)\\g(2)=56

Then put f(2) to subtract g(2)

f(2)-g(2)=7-56\\f(2)-g(2)=-49

Therefore, the answer is (f-g)(2) = -49.
