B)y = 3x^2 - 3x-18

Step-by-step explanation:

y = (3x – 9)(x + 2)

y = 3x*x+3x*2-9*x-9*2

y = 3x^2 +6x-9x-18

y = 3x^2 - 3x-18

Price after clearance:

Pc = 120 - (120/100×20)

Pc = 120 - (1.2×20)

Pc = 120 - 24

Pc = 96

Price after sales tax:

P = Pc + (Pc/100×5)

P = 96 + (96/100×5)

P = 96 + (0.96×5)

P = 96 + 4.8

P = $100.80

How do I construct a sample data set for which n=7, x=9(x bar), and s=0?

JulijaS [17]

When the standard deviation = 0, there is no deviation at all. So the numbers are all the same. And there are seven of them. And the average is nine.
So the sample data set would just be seven 9s.
