Answer:
By one week, Ander will have washed 105 bikes.
Step-by-step explanation:
First, you need to find the rate of how many bikes Ander can wash per day. You do this by dividing 75 and 5 which would result in 15. You need to know how much he washes per week so you multiply 15 x 7=105. Hope this helps. Please rank brainliest!
I think it is 0.5 per min
Answer:
B)Margin of error becomes smaller
Step-by-step explanation:
given that you are conducting a poll to determine the percentage of adults who gamble at least once a month.
when sample size increases we find that n increases.
Standard error = std deviation / square root of n
Since standard error is inversely proportional to square root of n, we find that as n increases standard error decreases.
This results in reduction of margin of error.
So margin of error becomes smaller whenever sample size becomes larger
As a result confidence interval will get narrower.
B)Margin of error becomes smaller
2) The reason that you would select the option that you did above is due to what is known as _____inverse relation between n and margin of error.
Answer: <u>The quotient of 4 / </u><u> The answer after we divide one number by another. dividend ÷ divisor = quotient. Example: in 12 ÷ 3 = 4, 4 is the quotient.</u>
Answer: <u>a number decreased by 8 / When you say a number decreased by eight, then it means that there are 2 defined numbers, and the difference between the 2 numbers is eight</u>
Answer:
Step-by-step explanation:
Given
--- base of the tank base
--- height of the tank base
--- height of the tank
Required:
Determine the volume of water needed for 6 inches below the top
First, calculate the area of the tank base.
If the tank is filled 6 inches below the top, this means that the height of the water is H - 6.
So, the volume is:
Substitute 240 for Area and 36 for H
