Hello,
The inverse of the function is f^-1(X)=-3-x
How?
f (x)=-x-3
replace f(X) with y
y=-x-3
interchange the variables
x=-y-3
solve for y and replace f^-1 (X)
Hope this helps
Answer:
40
Step-by-step explanation:
Use the ratio 5:3 to answer the question.
5 = made free throws
3 = missed free throws
If she misses 24 free throws, compare the ratios 5:3 to x:24 (you are solving for x)
24 divided by 3 is 8, so multiply 5 by 8
You would get 40
Answer:
b
Step-by-step explanation:
given s(t) = t³ - 5t then
v(t) = s'(t) = 3t² - 5 and
v(3) = 3(3)² - 5 = 22 m / s, and
a(t) = v'(t) = 6t, then
a(3) = 6 × 3 = 18 m / s²
Answer:
Step-by-step explanation:
Given that in our industry on average a firm paid out record year end bonuses of $125,500 per employee for 2008. We would like to take a sample of employees at our firm to see whether the mean year end bonus is different from the reported mean of $125,500 for the population.
1. Sample Mean =
118000
2. Population Mean = 125500
3. Population Standard Deviation = 30000
4. Sample size = 40
5. Alpha Error = 5%
6. Confidence Coefficient = 95%
7. Calculate Test Statistic = Mean difference /s td error = -1.581
8. Rejection Region Critical Value = If Z statistic is below -1.96 or above 1.96
This is false. However all squares are parrallelograms.
