Find the mean absolute deviation for the set below:

62, 71, 83, 110, 501, 94, 227

Answers

Answer 1

Answer:

(MAD) mean absolute deviation: 114.2

Step-by-step explanation:

Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164

164 - 62 = 102

164 - 71 = 93

164 - 83 = 81

164 - 110 = 54

164 - 501 = 337

164 - 94 = 70

164 - 227 = 63

Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 =  114.2

Answer 2

Answer:

Step-by-step explanation:

First, add all the numbers and count the total amount of numbers.

Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.

Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)

Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.

Then, you have the M.A,D ( Mean Absolute Deviation )

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

216 miles :3

Step-by-step explanation: alright so  is it is 4.5 you just divide 1/4 by 4.5 (

18) 18 x 12 = 216 miles :3

Answer:

Step-by-step explanation:

1/4 inch=12 miles                               Harrisburg and Leighton= 4.5 inches

1) Set up a proportion: ¼ /12 miles = 4.5 inches/ x miles

(inches across from inches

miles across from miles )

2) Use cross-products to solve: ¼x= 12(4.5)

                           ¼x/¼ = 54/ ¼

                                       x=216miles

The distance between Harrisburg and Leighton is 216miles

Answer:

No, they are not in proportion

Step-by-step explanation:

As when we cross-multiply 2/3 and 7/10, we get 20 = 21

When we cross-multiply 1 and 3/5, we get 5 = 3

When we cross-multiply 4/3 and 1/2, we get 8 = 3

20=21 ≠ 5=3 ≠ 8=3

∴ Hence, they are not in proportion.

8th/9th-95 POINTS+BRAINLIEST!!!!!!!! How do you write a quadratic equation in vertex form? Please explain the steps in simple language and use y=x²+6x+16 as an example.

Answers

Answer:

In vertex form: y = 1(x - (-3))² + 7

Vertex: Minimum (-3, 7)

Explanation:

Vertex form: y = a(x - h)² + k

Completing square (rules) :

1st rule: (x + d)² = x² + 2dx + d²    and   (x - d)² = x² - 2dx + d²

2nd rule: x² + 2dx = (x + d)² - d²   and  x² - 2dx = (x - d)² - d²

Given equation:

y = x² + 6x + 16

y = x² + 2(3)x + 3² + 7

y = (x + 3)² + 7

Into vertex form:

y = 1(x - (-3))² + 7

From this identify:

a = 1, h = -3, k = 7

Solution, vertex of this equation: Minimum (-3, 7)

So you find the a and b in (x-a)^2+b. A is 3 and b is 7.

Answers

Answer:

The point closest to the number 40

Step-by-step explanation:

To find volume of cone:

\(V=\pi r^{2} \frac{h}{3}\)

(but in this case we will be substituting \(\pi\) for it approximation: 3.14)

So our new equation is \(V= 3.14r^{2} \frac{h}{3}\)

All right, let's get to work now.

Following the order of operations our first step would be: \(3^{2}\) or 3x3 wich is 9Next step would be 3.14x9, which is 28.26After that we would solve \(\frac{4}{3}\), which is 1.3 repeating but we can round to the nearest tenth and get 1.3Next we would multiply 28.26 by 1.3 which is 36.73800

Step-by-step explanation:

It's B.

Let's rewrite the expression like this :

and try given values for x :

if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrong

Use the equation below to find v, if u=17, a=4, and t=8. 4=u+at

Answers

Answer:

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Step-by-step explanation:

The given equation is:

4 = u + at

where u = 17, a = 4, and t = 8.

Substituting the given values, we get:

4 = 17 + 4(8)

Simplifying the right-hand side:

4 = 17 + 32

Combining like terms:

4 = 49

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

This question is not solvable. If the equation is 4=u+at, with u=17, a=4, and t=8, that would make the equation be 4=17+4*8. This ends up as 4=17+32, which is equal to 4=49, which is not true.
