The set given by the project grade is {1, 2, 3, 4, 5}. If the random variable, X, is the project grade, the mean of the probability distribution is determined by:
Sum = 1 + 2 + 3 + 4 +5
= 15
Mean of the probability distribution is 15/n, where n = 5
= 15/ 5
= 3
First, find the area of the whole square.
Area= Base times height= 48 times 96 = 4608
Next, find the area of ONE circle. The diameter is 12, so the radius would be 6
A=πr sqaured= 3.14 times 6 squared = 113.04
Next multiply by 3, since there are 3 circles.
113.04 times 3 =339.12
Subtract this value from the total area (4608)
4608-339.12=4268.88
ANSWER: 4268.88
Answer:
he makes 14 field goals and 7 extra point kicks
Step-by-step explanation:
- f=#of field goals
- e=extra kick points
- f+e=21
- 3f+1e=49
- subtract top from bottom
- 2f=28
- f=14
