Answer:
the mean is 12.6 and the median is 12
Step-by-step explanation:
to find the mean add all the values together and divide by the total amount of values, in this case is 9
to find the median, line up all numbers in order from smallest to largest, and the middle value is the median in this case is 12
Answer:
- 2 and 7
Step-by-step explanation:
A polynomial P(x) divided by (x + h) has remainder f(- h) ← remainder theorem
P(x) divided by (x + 5) has remainder P(- 5) = - 2 ( from result given )
P(x) divided by (x - 3) has remainder P(3) = 7 ( from result given )
F(x) = 2x - 10
let y = f(x)
y = 2x - 10 solving for x.
y + 10 = 2x
2x = y + 10
x = (y + 10)/2
Recall f(x) = y. Implies x = f⁻¹(y)
<span>x = (y + 10)/2
</span>
f⁻¹(y) <span>= (y + 10)/2
</span>
So as well:
f⁻¹(x) <span>= (x - 10)/2</span>
