Step-by-step explanation:
Okay I'm not sure but I found an article online that seemed explanatory so here ya go
Solution: We are given:
μ=3.1,σ=0.5,n=50
We have to find P(Mean <2.9)
We need to first find the z score
z= (xbar-μ)/(σ/sqrt(n))
=(2.9-3.1)/(0.5/sqrt(50))
=(-0.2)/0.0707
=-2.83
Now we have to find P(z<-2.83)
Using the standard normal table, we have:
P(z<-2.83)=0.0023
Therefore the probability of the sample mean being less the 2.9 inches is 0.0023
The Answer is 0.15, you count all the decimal points places and move that amount.

Step-by-step explanation:
if you divide an arc's degree measure by 360°
you find the fraction of the circle's circumference that the arc makes up Then if you multiply the length all the way
Answer:
You will have $20,495.30
Step-by-step explanation:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved.
