Mean= is the summation of the maximum temperatures ÷ the numbers of times the temperatures where recorded

standard deviation= is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.

A low standard deviation means that most of the numbers are very close to the average.

A high standard deviation means that the numbers are spread out.

Variance= is a way to measure how far a set of numbers is spread out.

A variance of zero indicates that all of the data values are identical. All non-zero variances are positive.

A small variance indicates that the data points tend to be very close to the mean, and to each other.

A high variance indicates that the data points are very spread out from the mean, and from one another.

if the lesser of two consecutive even integers is seven more than half the greater, what are the two integers?
beks73 [17]

Answer: 16 and 18

Step-by-step explanation:

Let the lesser of two consecutive even integers is x.

Hence, the bigger of two consecutive even integers is (x+2).

\displaystyle\\x-\frac{x+2}{2}=7 \\

Multiply both parts of the equation by 2:

x(2)-(x+2)=7(2)\\2x-x-2=14\\x-2=14\\x-2+2=14+2\\x=16\\x+2=16+2\\x+2=18

HELP MEEEE PLZ. <br> i need to Find the surface area and volume
lisabon 2012 [21]

Answer:

A ≈ 494.80 mm^{2}

V = 827.02 mm^{3}

Step-by-step explanation:

height ( <em>h </em>) = 13 mm

radius ( <em>r </em>)  = \frac{9mm}{2} = 4.5 mm

Surface area  = 2\pi rh + 2\pi r

                      = 2π(4.5)(13) + 2π(4.5)

                      ≈ 494.80 mm^{2}

Volume = \pi r^{2} h

<em>              </em>= \pi (4.5)^{2} (13)

             = 827.02 mm^{3}
