A figure with two circular bases and one curved surface is called a cylinder
The standard deviation of the mileage for the sample of convertibles is 1.98977 miles.
<h3>What is standard deviation? </h3>
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.
<h3>What is the standard deviation of the mileage? </h3>
In order to determine the standard deviation, take the following steps:
- Determine the mean of the observation:
(25 + 25 + 24 + 21 + 21 + 21 + 20) / 7 =22.43
- Determine the difference between each value and the mean and then square the result:
(25 - 22.43)² = 6.6049
(25 - 22.43)² = 6.6049
(24 - 22.43)² = 2.4649
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(20 - 22.43)² = 5.9049
Sum of squared difference = 27.7143
- Determine the mean of the square differences and then find the square root of the mean:
√27.7143 / 7 = 1.98977

1 liter equals to 2.11338 pints
When converting 100 liters to pints you would do 100 * 2.11338, or move the decimal place two places to the right, so you have 211.338 pints.
Answer:
2(4a+b-2)
Step-by-step explanation:
All you need to do is factor out 2 from the expression. (sorry if this is wrong)
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one
m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one
