What is the estimated mean absolute deviation of the population? {76,67,80,83,79,76,76,82,82

The mean is 77.9 so subtract each number from the mean (if it’s negative just keep the number the same and change it to positive). Once you have subtracted the mean from all the numbers (or vise versa as long as it’s positive) add the differences together and find the mean of them. There’s your answer. ☺️

You can't really say the absolute deviation of the population to me but if you wanted to you could

The figure below is from a quilting pattern. The indicated angles are Supplementary. What is the news he or N and the two angles

VashaNatasha [74]

Answer:

The value of N is 8

The value of the angles is 48º

Explanation:

The two indicated angles are supplementary because they could be drawn as two interior angles on the same side of two parallel sides cut by a transversal.

Thus, those measure of those two angles add up 180º, which lets you to write an equation and solve for N:

8N - 16 = 6N

8N - 6N = 16

2N = 16

N = 16 / 2

N = 8

And the value of the angles is:

8N - 16 = 8(8) - 16 = 48, or

6N = 6(8) = 48

Do you know how to do this question

Sever21 [200]

Percentage of the area shaded = 55%

Solution:

Perimeter of the square = 40 cm

Each side of the square = $\frac{40}{4}$ = 10 cm

Area of the square = $\text{side}^2$

= 10²

= 100

Total area of the square = 100 cm²

The unshaded portion is two triangles.

Base of the smaller triangle = 10 cm – 7 cm = 3 cm

Height of the smaller triangle = 10 cm

Area of the smaller triangle = $\frac{1}{2}\times \text{base}\times \text{height}$

$$=\frac{1}{2}\times 3\times 10$

Area of the smaller triangle = 15 cm²

Base of the larger triangle = 10 cm – 4 cm = 6 cm

Height of the larger triangle = 10 cm

Area of the larger triangle = $\frac{1}{2}\times \text{base}\times \text{height}$

$$=\frac{1}{2}\times 6\times 10$

Area of the larger triangle = 30 cm²

Area of the shaded portion = Area of the square – Area of the smaller

triangle – Area of the larger triangle

= 100 cm² – 15 cm² – 30 cm²

Area of the shaded portion = 55 cm²

Percentage of the area shaded = $\frac{\text{Area of the shaded portion}}{\text{Total area of the square}}\times100\%$

$$=\frac{55}{100}\times100\%$

Percentage of the area shaded = 55%

ok KO of mass 550 gram has three ingredients flour sugar and raisins there is twice as much as flour sugar and one and a half ti

brilliants [131]

Answer:

2S = F

1.5R = S or R = S/1.5

So flour F and sugar S and raisins R

F + S + R = 550

2S + S + S/1.5. = 550

3S + 1.5S + S = 550*1.5

5.5 S = 550*1.5

S = 100*1.5

S = 150

R= 100

And so flour ie, F = 300

I NEED HELP BEFORE 10:00 A.M!

Answer:

A. = 20 in²

B. = 45 ft²

C. = 29.5 ft²

D. = 36 ft²

E. = 28 ft²

Step-by-step explanation:

A. Formula = A = (h_b b)/2 = base 10 ft height_b= 4ft = 20 ft²

B. We have a rectagnle and a triangle: Formula: A = lw

= A = 30 ft² and now the triangle with the same formula as above: A = 15 ft²

30 ft²+15 ft² = 45 ft²

C. we have 2 rectagnle and a triangle: First the small recangle: A= lw = A = 1ft x 2ft = 2ft²

Second rectangle: 5 ft x 4 ft = 20 ft²

Right angeled triangle Formula: (ab)/2 = 3 ft x 5 ft = 7.5 ft²

Add it all together: 2ft²+20ft²+7.5ft² = 29.5 ft²

D. is a rectangle and a triangle: 8 ft x 3 ft = 24ft²

the triangle 8 ft x 2ft = 12 ft²; add 24 ft²+12 ft² = 36ft²

E. is a right-angled triangle (see fromula above) = (14 ft x 4 ft)/2 = 28ft²
