Part A: What is the mean of the data? Show your work.


Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work.

Answers

Answer:

Part A: 5  

Step-by-step explanation:

4+ 3+ 4+ 5+ 6+ 6+ 8+ 4= 40

so there is 8 numbers which means that we need to do 40 divided by 8=5

Part b: i dont know how to explain but the mad is  1.25.

The mean of given data is 5 and mean deviation is 1.25

What is mean deviation?

The mean deviation is defined as a statistical measure that is used to calculate the average deviation from the mean value of the given data set.

Mean = Sum of all observation/ Number of observation

         = 40 / 8

         = 5

                            = 1.25

Thus, The mean of given data is 5 and mean deviation is 1.25

Find the x-intercept of the function y=−0.2x+0.55

Answers

Answer:

2.75

Step-by-step explanation:

y=0

−0.2x+0.55=0

0.2x=0.55

x=2.75

Answer:

x=-2.75

Step-by-step explanation:

Plug y=0 into the equation and solve for x:

y=-0.2x+0.55

0=-0.2x+0.55

-0.55=0.2x

-2.75=x

Therefore, x=-2.75

what is the area of the triangle?

Answers

Answer:

S = S(ABCD) - S(BCE) - S(AED) = 7*6 - 2*6/2 - 5*6/2 = 42 - 6 - 15 = 21

Step-by-step explanation:

If we look at the picture, we can notice that the area we are interested in is S(ABCD) - S(BCE) - S(AED). Y-axis is parallel to AB line since the coordinates of the A and B points have the same X-axis value.

The following calculations happend for figuring out the width for each line:

AB = | -3 - 4 | = 7BC = | -4 - 2 | = 6CE = | 4 - 2 | = 2ED = | 2 - (-3) | = 5AD = | -4 - 2 | = 6

The formulas for each figure area:

S(ABCD) = AB * BCS(BCE) = BC * CE / 2S(AED) = ED * AD / 2
i agree that it is 21

Answer:

See work, below.

Step-by-step explanation:

The radius of this circle is 10 and so the diameter is 20.  The measure of the angle opposite side x is found as follows:

                      adj side

 cos theta = ------------------- = 18/20.  Find theta:

                      hypotenuse

theta = arccos 18/20 = 0.451 radian.

Now use the sine function to find x:

                                          x                       x

sin 0.451 radian      = ------------------- = ------------- = 0.651

                                    hypotenuse          20

which results in x = 20(0.651) = 13.02

x = 13.02 units

I should have used the Pythagorean Theorem up front.

18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

Answers

There are 4 triangles and the formula for the area of a triangle is 1/2BH so 11x10 is 110 and then take half of that and you’ll get 55. Since there are 4 triangles you need to then multiply that by 4 to get 220. And then you have to find the area of the square base which is 11x11 which will come out to 121. So you add the 220 and 121 to get 341.

180-170=10

theres 180 beacuse every straight line has the angle of 180

Answer:

x = 10

These 3 angles are supplementary so they all equal 180:

92 + x + 78 = 180

x + 170 = 180

Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?

Part A

Which equation represents the situation?
0.75s = 31.50
34(18s) = 31.50
0.75(s + 31.50) = 18
34(18 + s) = 31.50
Part B

Use the Distributive Property to solve the equation.
Enter your answer in the box.

Answers

Answer:

`Part A:

D. 3/4(18 + s) = 31.50

Part B:

$36

Step-by-step explanation:

I think 34 is 3/4, is that right?

here, s is the cost of the skirt

Part A: The answer would be:

3/4(18) + 3/4(s) = 31.5 =

3/4(18 + s) = 31.5

Part B: 3/4(18) + 3/4(s) = 31.5

4.5 + 3/4s = 31.5

Subtract 4.5 from both sides:

3/4s = 27, 27 is the cost of the skirt now, but we need the original price.

multiply both sides by 4/3:

s = 36

Answer:

A = 168 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 8 + 16 = 24 and h = 14 , then

A = [tex]\frac{1}{2}[/tex] × 24 × 14 = 12 × 14 = 168 m²

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55


Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

D. It shows the distance traveled, in miles, by the towboat after 5.25 hours.

I think the Answer is D
The answer is B because the hours would be the bottom intervals of 1 and the distance traveled (in miles) is the constant of 5.25. So, overall in one hour, you would’ve traveled 5.25 miles. (It’s like driving a car... you’d be going at a speed of 5.25 mph (which is kinda slow).
