Answer:
74
Step-by-step explanation:
You just have to substitute r with 5.
Now, the equation looks like this:
Next, solve first according to PEMDAS
And equals 75
Lastly, do which equals 74
Therefore, 74 is your answer.

Answer:
Step-by-step explanation:
The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).
How was this obtained. notice that if x = 0 then
f(0) = 2(3*0+4)(0^2 + 2)
f(0) = 2(4)(2)
f(0) = 16 just as the graph tells us.
Answer:
0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
Step-by-step explanation:
The following information is missing:
The standard deviation of population is 100.
We are given the following information in the question:
Population mean, μ = 502
Standard Deviation, σ = 100
Sample size, n = 90
Standard error =
Formula:
P(test score within 10 points)
0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
