Hey there Hailey!

So, to start this all of, what formula are we even going to use.

The formula that we will be using in this question would be . . .

\left[\begin{array}{ccc}\boxed{V= \pi r^2 \frac{h}{2}} \end{array}\right]

So, now that we know what formula that we will use, we will now plug in those number's into the formula.

Justification:

We do, 9 = (height)*3=(radius) \ but \ using \ the \ formula \ also.


\left[\begin{array}{ccc}27*3.14= \boxed{84.78} \\ Your \ correct \ answer \ would \ be \ \boxed{\boxed{27}}\end{array}\right]

Hope this helps you!

What value is equivalent to:<br> (8*4*2/8*7)^2 x (8^0/7^-3)^3 x 7^-9???
ankoles [38]

(8*4*2/8*7)^2 x (8^0/7^-3)^3 x 7^-9

Simplify the equations:

(8*4*2/8*7)^2 = (64/56)^2 = (8/7)^2

(8^0/7^-3)^3 = (1/7^-3)^3 = 7^9

Now you have :

(8/7)^2 x 7^9 x 7^-9

Multiply 7^9 x 7^-9 by adding the exponents to get 7^0, which = 1

Now you have:

(8/7)^2 x 1

(8/7)^2 = (8x8) / (7x7) = 64/49

64/49 x 1 = 64/49

The scores on a statistics test had a mean of 81 and a standard deviation of 9. One student was absent on the test day, and his
Rama09 [41]

Using the definitions of the mean and of the standard deviation of a data-set, we have that:

  • The mean would increase.
  • The standard deviation would remain constant.

<h3>What are the mean and the standard deviation of a data-set?</h3>

  • The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
  • The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.

When the measure of 84 is added to the data-set, we have that:

  • A measure greater than the mean is added, hence the mean would increase.
  • The difference squared between 84 and the mean of 81 is of 9, which is the same as the standard deviation, which would remain constant.
