Answer:
On the average, estimates will be either be 0.2 meters too short or too long.
Step-by-step explanation:
Standard deviation is normally used to show how the actual value of a variable in a given sample deviates from the mean or average value of the sample. The deviation could be slightly more or less than the average value by the value of the standard deviation. Therefore, in this question, the standard deviation shows that the estimates could be 0.2 m short or more than the mean.
Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283

You can use sigma notation to represent an infinite series. For example, ∞∑n=110(12)n−1 is an infinite series. The infinity symbol that placed above the sigma notation indicates that the series is infinite. To find the sum of the above infinite geometric series, first check if the sum exists by using the value of r .
