The following data show the height, in inches, of 11 different plants in a garden: 9 4 10 9 5 2 22 10 3 3 5 After removing the outlier, what does the mean absolute deviation of this data set represent?

Answers

Answer 1

Answer: The outlier is the obviously different data among the whole group of data points. In this case, the outlier is 22. When you find the mean, you only use the data points without the outlier. Therefore,

Mean = (9+4+10+9+5+2+10+3+3+5)/10 = 6

Then, the mean absolute deviation is

∑(x-mean)^2/n, where x is every single data point and n is the number of data points which is equal to 10

|9-6|+|4-6|+|10-6|+|9-6|+|5-6|+|2-6|+|10-6|+|3-6|+|3-6|+|5-6| = 28

Then,

Mean Absolute Deviation (MAD) = 28/10 = 2.8

This is the average distance of the data from the mean.

Answers

Jim and Jo both ate 9 bananas and what I did is add 6+3 = 9. Now I am going to figure out how many Jack ate by adding 9 +5=14. So:

Jim ate 9 bananas
Jo ate 9 bananas
Jack ate 14 bananas

Find the perimeter of a rectangle whose length is 3 square root 5 and width is 2 square root 7

Answers

The rectangle has a length of 3√5 and a width of 2√7. The perimeter is calculated as 23.9 approximately.

Use the concept of a rectangle defined as:

Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.

Given that,

Length of the rectangle: 3√5

Width of the rectangle: 2√7

To find the perimeter of a rectangle,

Use the formula P = 2(length + width).

In this case,

The length is 3√5 and the width is 2√7.

Applying the formula, we get:

P = 2(3√5 + 2√7)

To simplify this expression, distribute the 2:

P = 6√5 + 4√7

p ≈ 23.9

Hence,

The perimeter of the rectangle is approximately 23.9.

The Patels took out a 15-year mortgage. How many monthly payments will they have to make on this mortgage? A. 360
B. 60
C. 180
D. 90

Answers

There are 12 months in a year, and 15 years to pay the mortgage.

Therefore you are simply doing 12 multiplied by 15.

12 × 15
= 180

So your answer is C. 180

Final answer:

To calculate the total number of mortgage payments over a period of 15 years, one should multiply the number of years by 12. Thus, a 15-year mortgage will have 180 payments in total.

Explanation:

The Patels took out a 15-year mortgage. A mortgage is usually paid on a monthly basis. Therefore, to calculate the total number of payments the Patels will make, multiply the number of years by 12 - the number of months in a year. So, 15 years * 12 months/year equals 180 payments. Therefore, the correct answer is C. 180.
