Answer:
c
Step-by-step explanation:
the reasoning for this is because it is technically 2 squared times 3 but 2x2x3 is the same thing
The probability that a randomly selected runner has a time less than or equal to 3 hours and 20 minutes is 0.16 or 16%.
<h3>What is normally distributed data?</h3>
Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data.
The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The times of the runners in a marathon are normally distributed, with
- Mean of 3 hours and 50 minutes
- Standard deviation of 30 minutes.
Refere the probabiliity table attached below. The probability of Z being inside the 1 Standard daviation of mean is 0.84.
The probability of runner selected with time less than or equal to 3 hours and 20 minutes,

Thus, the probability that a randomly selected runner has a time less than or equal to 3 hours and 20 minutes is 0.16 or 16%.

Step-by-step explanation:
A coefficient is a number that is before a variable and in this case it’s 9 and 4 that are before the variables x and y.
Answer:
D, 1250 square feet
Step-by-step explanation:
Area of a circle:

Diameter is twice the radius, so the radius is 20 ft.
Thus the area of grass is 400pi
