3x(1.05) = 3.15x
1.05x + 1.05x + 1.05x = 3.15x
Answer:
3rd option
Step-by-step explanation:
We first need to find the diameter of the circle.
We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.
The diagonal of a square is

where a is the side lengths of the square.
So this means the diagonal of the square is

The diagonal is also the diameter of the main circle. The formula for circumference is

where d is the diameter.
So the diameter is

or

The third option is correct
(2n + 5k)^2 = (2n + 5k)(2n + 5k)
Here we need to use FOIL
First - 2n * 2n = 4n^2
Outside - 2n * 5k = 10nk
Inside - 5k * 2n = 10nk
Last - 5k * 5k = 25k^2
That gives us 4n^2 + 10nk + 10nk + 25k^2, we can combine 10nk + 10nk to give 20nk, and a final equaion of 4n^2 + 20nk + 25k^2

Answer:
D.) If the mean typing speed of workers from the agency is 60 wpm, the probability of selecting a sample of 50 workers with mean 58.8 wpm or less is 0.267.
Step-by-step explanation:
In this case, the p value is what let's us determine the probability of getting the desired outcome. This would be 60 wpm.
If it is lower than the desired outcome, we know that this inference is not the <em>actual mean </em>of the data.
