Answer:
c. approximately 90.07%
Step-by-step explanation:
We need to calculate z-statistic of 30 inches of rain in the normal distribution with an average of 35.4 inches of rain each year, and a standard deviation of 4.2 inches.
z score can be calculated using the formula
z=
where
- M is the average rain in inches (35.4)
- s is the standard deviation (4.2)
using the numbers we get z=
≈ −1,286
Then percentage of years does Ithaca get more than 30 inches of rain is
P(z>-1.286) =1- P(z<-1.286)=1-0.0993 ≈0.9007 or 90.7%
4 (x-3)=3x-4
4x-12=3x-4
4x-12-3x=3x-4-3x
x-12=-4
x-12+12=-4+12
x=8
Answer:
9.1
Step-by-step explanation:
he needs one box
he needs 4 individuals 1.39×4=5.56
6 x.59=3.54
5.56+3.54=9.1
First we compute the distance between the center and the given point which is exactly the radius
r =

Now that we know the center and the radius, we can write the equation of a circle with given radius and center:

where (h,k) represent the coordinates of the center (3,7).
We substitute and obtain
