Answer:
0.19
Step-by-step explanation:
μ = 160 and σ = 50. Find the z scores for 180 and 210.
z = (x - μ) / σ
z = (180 - 160) / 50 = 0.40
z = (210 - 160) / 50 = 1.00
So we want P(0.40<z<1.00). This can be found as:
P(0.40<z<1.00) = P(z<1.00) - P(z<0.40)
Now use a calculator or table to find each probability:
P(0.40<z<1.00) = 0.8413 - 0.6554
P(0.40<z<1.00) = 0.1859
Rounded to the nearest hundredth, P ≈ 0.19.

How to Multiply Fractions?
Here are the steps:-
<u />
- Turn any whole numbers into fractions (example:- 3 = 3/1)
- Multiply the numerator of the first fraction times the numerator of the 2nd fraction; same with the denominator.
So let's do it.
Step 1:-

Step 2:-


We can't simplify this fraction, but there's something else we can do:-
