Answer:

19.625cm squared because you have to divide the diameter by 2 to get the radius.

area of circle=pi times radius times radius

=3.14 times 2.5 times 2.5

=19.625cm squared

What is the slope, m, of the line through (-7, -2) and (-6, 7)?

Nataliya [291]

Answer:

Slope = 9

Step-by-step explanation:

(-7 , -2) ; x₁ = -7 and y₁ = -2

(-6 , 7) ; x₂ = -6 and y₂ = 7

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9$

The manager of a warehouse would like to know how many errors are made when a product's serial number is read by

Inessa05 [86]

Answer:

14.625

Step-by-step explanation:

As per the situation the solution of mean and standard deviation change, based on all 12 samples is represented below:-

Mean of all 12 samples is shown below:-

$= \dfrac{Sum \ of \ all \ the \ observations}{Total \ number \ of \ observation}$

$= \dfrac{36+14+21+39+11+2+33+45+34+17+1+29}{12}$

So, the Mean = 23.5

and now,

The Standard deviation of all 12 samples is shown below:-

$= \sqrt{\frac{1}{12}} (36-23.5)^2+(14-23.5)^2+(21-23.5)^2+(39-23.5)^2+(11-23.5)^2+(2-23.5)^2+(33-23.5)^2+(45-23.5)^2+(34-23.5)^2+(17-23.5)^2+(1-23.5)^2+(29-23.5)^2}]$

$\sigma$ = 14.625

Therefore, we used the above equation to reach the answer.
