Answer:

6(m-2)

Step-by-step explanation:

Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-

Answer is: 6(m-2)

Answer:

6(m-2)

Step-by-step explanation:

it is 6(m-2) because you would do the whole length of m minus 2.

It is given that one number is 6 more than another. If three times the sum of the two numbers is equal to 22 more than the large

Irina-Kira [14]

Answer:

First number=22

Second number=28

Step-by-step explanation:

Since you don't know either of the numbers we can call the first number x. The second number is the first number plus 6 or x+6. The sum is 22 more than the larger number so x+6+22 or x+28. Using this we can create the equation x+x+6=x+28. In order to isolate x we would subract x from both sides ending up with x+6=28. Then subract 6 from both sides to get x=22. This means the first number equals 22. Then to solve for the second number you plug 22 in for x to get the equation 22+6= the second number, so the second number is equal to 28. Look below for just the equation.

x+x+6=x+6+22

2x+6=x+28

-x -x

x+6=28

-6. -6

x=22

22+6

=28

22+28= 28+22

Some values of a linear function are shown in this table:

viva [34]

9514 1404 393

Answer:

5.5

Step-by-step explanation:

The rate of change is given by the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (16.5 -11)/(3 -2) = 5.5/1

m = 5.5

The rate of change of this function is 5.5.

g The data below represent a random sample of 9 scores on a statistics quiz. (The maximum possible score on the quiz is 10.) Ass

FrozenT [24]

Answer:

95% Confidence interval: (5.5,8.5)

Step-by-step explanation:

We are given the following data in the question:

8,10,8,4,5,7,3,10,8

Sample size,n = 9

Population standard deviation = 2.3

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{63}{9} = 7$

Sample mean = 7

95% Confidence interval:

$\mu \pm z_{critical}\dfrac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$7 \pm 1.96(\dfrac{2.3}{\sqrt{9}} ) =7 \pm 1.5 = (5.5,8.5)$

is the required confidence interval for population mean.
