Pls solve the following equation. 25 = 5x

a. Fill in the midpoint of each class in the column provided. b. Enter the midpoints in L1 and the frequencies in L2, and use 1-

Tresset [83]

Answer:

$\begin{array}{ccc}{Midpoint} & {Class} & {Frequency} & {64} & {63-65} & {1} & {67} & {66-68} & {11} & {70} & {69-71} & {8} &{73} & {72-74} & {7} & {76} & {75-77} & {3} & {79} & {78-80} & {1}\ \end{array}$

Using the frequency distribution, I found the mean height to be 70.2903 with a standard deviation of 3.5795

Step-by-step explanation:

Given

See attachment for class

Solving (a): Fill the midpoint of each class.

Midpoint (M) is calculated as:

$M = \frac{1}{2}(Lower + Upper)$

Where

$Lower \to$ Lower class interval

$Upper \to$ Upper class interval

So, we have:

Class 63-65:

$M = \frac{1}{2}(63 + 65) = 64$

Class 66 - 68:

$M = \frac{1}{2}(66 + 68) = 67$

When the computation is completed, the frequency distribution will be:

$\begin{array}{ccc}{Midpoint} & {Class} & {Frequency} & {64} & {63-65} & {1} & {67} & {66-68} & {11} & {70} & {69-71} & {8} &{73} & {72-74} & {7} & {76} & {75-77} & {3} & {79} & {78-80} & {1}\ \end{array}$

Solving (b): Mean and standard deviation using 1-VarStats

Using 1-VarStats, the solution is:

$\bar x = 70.2903$

$\sigma = 3.5795$

See attachment for result of 1-VarStats

Triangle RST is rotated 90° in a clockwise direction. What is the name of the image after the rotation?

Art [367]

When the triangle RST is rotated by 90° in a clockwise direction, the name of the image after the rotation would be SRT.

The reason you get a name like this is because you're not only rotating the triangle, you also rotating the letters along with the image.

Ella already knew 5 appetizer recipes before starting culinary school, and she will learn 2 new

Natalija [7]

A = 2w+5

example: on week three, she would have the recipes from the other weeks that you have to account for as well as the extra five

2(3)+5=11 so A would equal 11 by week three.

Use multiplication because it is essentially repeated addition.

2(from week 1) + 2(from week 2) + 2(from week 3) + 5(prior to school) =11

Value of x 9(2x-1)-9x - 18

bixtya [17]

Let's simplify step-by-step.9(2x−1)−9x−18

Distribute:=(9)(2x)+(9)(−1)+−9x+−18=18x+−9+−9x+−18

Combine Like Terms:=18x+−9+−9x+−18=(18x+−9x)+(−9+−18)=9x+−27

Answer:=9x−27
