Answer:
M=92
Step-by-step explanation:
In order to get M by itself, you want to get rid of the -32. To counteract this negative, you do the inverse of subtraction which would be addition. When you add 32 to one side, you have to add 32 to the other side. Your set up would look something like this.
M=60+32
Add 60 and 32 together to get..
M=92

Step-by-step explanation:
Hello!
The population mean (μ) is a measure of central tendency, this means, it shows you the position of the distribution. Changing the value of the mean changes the position of the bell over the axis but there is no change in its shape. The three normal distribution have the same standard deviation (δ), so they will have the same shape and only their positions vary.

I hope it helps!
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
