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

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

It’s pretty self explanatory

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.

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).

 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

28 out of 50 8th graders said they prefer snow to rain. 42 out of 58 10th graders said they prefer snow. did a larger percentage of 8th graders or 10th graders prefer snow?

explanation please

Answers

A larger percentage of 10th graders preferred snow.

Answer:

10th graders prefered snow then 8th graders did.

Step-by-step explanation:

Hey I hope I will be able to help!

To find out the percentage we need to divide the fractions-

28 divided by 50 = 0.56 and in percentage form its 56%

42 divided by 58 = approximately 0.72 which is 72%

56% < 72%

72% is obviously greater so 10th graders prefer snow more than 8th graders do.

I really need help finding the surface area

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.

First, subtract 10 from both sides.

x + 10 ≥ 6

A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?

Answers

Answer:

n=90

Step-by-step explanation:

As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one  

so volume = length * width * height

volume of larger prism

vp=45/4 ft^3 =11.25

volume of small cubes

vs=1/2*1/2*1/2

vs=0.125 ft^3

now numbers of cube that can fit

n=vp/vs

n= 11.25/.125

n=90

so 90 smaller cubes will completely fill in the prism

Answer:

11.25 [tex]ft^3[/tex]

Step-by-step explanation:

2.5 x 3 x 1.5 = 11.25 [tex]ft^3[/tex]
