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:
48
Step-by-step explanation:
((8+16)÷2)×4=48
so the area would be 48
Answer:
well there is no integer number so the answer could be 5.5
Answer: The fourth number line represents the solutions to –2|x| = –6
Step-by-step explanation:
Given equation: 
To solve the given equation, first divide -2 on both the sides, we get
Thus the absolute value of x=3
We know that the absolute value is the distance between a number and zero.
Therefore, the distance between x and zero is 3
Therefore, x=3 and -3
This solution is represented by the fourth number line .
Answer:
y=2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-5)/(6-4)
m=4/2
m=2
y-y1=m(x-x1)
y-5=2(x-4)
y=2x-8+5
y=2x-3
