True mean/population mean
Step-by-step explanation:

Answer:
7%
Step-by-step explanation:
Step one:
given data
The original cost of Sam’s investment is $10,000
Sam calculated his real return to be $10,700
Required:
the interest made from the investment is
10700-10000= $700
Step two:
The ROI is a percentage that tells us the interest made
interest/investment*100
=700/10000*100
=0.07*100
= 7%
The ROI is 7%
Answer:
x = 0, x = 1, x = - 3
Step-by-step explanation:
To find the zeros, let f(x) = 0 , that is
(x - 1)(x(x + 1) + 2x) = 0 ← distribute and simplify parenthesis
(x - 1)(x² + x + 2x) = 0
(x - 1)(x² + 3x) = 0 ← factor out x from the second parenthesis
x(x - 1)(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x - 1 = 0 ⇒ x = 1
x + 3 = 0 ⇒ x = - 3
