Answer:
9000
Step-by-step explanation:
200x45=9000
Surface area of a sphere = 4πr^2
4πr^2=100π
Divide both sides by 4π
r^2=100
r=10
The radius is 10 cm.

Answer:
B. 97%
Step-by-step explanation:
20 students is -2 standard deviations away from the mean
35 is +3 standard deviations away from the mean
100 - 2.4 = 97.6
(2.4 is amount of data we are not using)
please refer to the standard deviation graph attached :)
Step-by-step explanation:
-1 is already a decimal.
For any fraction you can use: 2/3=x/100
After that, you get x=approx 0.66...
