Answer:
a. We are 99% confident that the average age of all golfers that play on the golf course is greater than 21.29
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
99% confidence interval for the average age of golfers that play on the area is (35.683, 43.763), which means that we are 99% confident that the mean age of all golfers who play in the area is a value in this interval, and the best conclusion is given by option A, as the lower bound of the interval is greater than 21.

Step-by-step explanation:
Answer: 2.44 inches
Step-by-step explanation:
Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.
The number of inches that are between the two cities will be represented by x. Therefore,
1/x = 45/110
Cross multiply
45x = 110
x = 110/45
x = 2.44 inches
The Distance between the two cities on the map is 2.44 inches
The formula of a volume of pyramid:



substitute

Answer:
M = 
Step-by-step explanation:
Given
w = 1000M - 200 ( isolate 1000M by adding 200 to both sides )
w + 200 = 1000M ( divide both sides by 1000 )
= M
