How to solve I can’t do it

10.94

Step-by-step explanation:

The standard deviation is calculated by using the following formula:

This means that N is the total number of cases you want to take into account, times the sum of x at the ith position - x squared.

In other words, the standard deviation in your example implies the following:

26 is the first value, so i = 1, 34 is the second value, so i = 2, 18 where i = 3, and so on and so forth, until you reach the end, which is 6 (so the initial value is 1 and the last one is 6).

You're doing a sum over an iteration of all the numbers in your sample.

So applying the sum of all of the numbers, it gives us the following:

The sum of all of the numbers in your sample is equal to 119.6.

Substitute into the equation once again:

Where the square root of 119.6 is 10.93617...

Rounded to two decimal places: 10.94

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
