Answer:
P(X
74) = 0.3707
Step-by-step explanation:
We are given that the score of golfers for a particular course follows a normal distribution that has a mean of 73 and a standard deviation of 3.
Let X = Score of golfers
So, X ~ N(
)
The z score probability distribution is given by;
Z =
~ N(0,1)
where,
= population mean = 73
= standard deviation = 3
So, the probability that the score of golfer is at least 74 is given by = P(X
74)
P(X
74) = P(
) = P(Z
0.33) = 1 - P(Z < 0.33)
= 1 - 0.62930 = 0.3707
Therefore, the probability that the score of golfer is at least 74 is 0.3707 .
Answer:1296
Step-by-step explanation:1200*.04=96
1200+96=1296
Answer:
Therefore,

Step-by-step explanation:
Let Assume Some Diameter of a Circle, to Solve it
Diameter = d = 14 inch ( say )
C =Circumference
Pi =constant = 3.14
To Find:
C = ?
Solution:
Formula for Circumference of a Circle is given as

Where,
C = Circumference
d = Diameter
Now Substitute d = 14 inches we get

This way we can find the circumference for any 'd' i.e Diameter
Therefore,
