Answer:
length = 7 units
width = 13 units
area = 91 square units
perimeter = 40 units
Step-by-step explanation:
What is the area of a rectangle?
❖ The area of a rectangle can be found by multiplying the length and
width of the rectangle.
What is the perimeter of a rectangle?
❖ The perimeter of a rectangle is the sum of all sides- length and
width. In this case, we're given the perimeter as 40 units and the
length as 7 units, but the width is unknown. Formula to find
perimeter of rectangle is 2(l + w) = P.

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 .
