Use the graph to determine the solution of the inequality |x + 1| + 2 > 5.
Aleks [24]

Use the graph to determine the solution of the inequality |x + 1| + 2 > 5.

To graph this , first we make the absolute function alone

|x + 1| + 2 > 5

to make absolute function alone we subtract 2 from both sides

|x + 1|  > 3

x+1 inside the absolute function . so x=-1

From -1, move 3 units to the right and 3 units to the left.

For x>2 , shade the graph to the right

For x< -4, shade the graph to the left

The graph is attached below

The solution to the inequality is x<-4 and x>2

Hui recorded the temperature at the same time each day for one month. He found that the MAD for his data set was 4.3.
Solnce55 [7]

Answer:

A. The lowest temperature varied only 4.3 degrees from the mean.

C. No temperature varied more than 4.3 degrees from the mean.

E. Temperatures generally increased or decreased by about 4.3 degrees from the mean.

Step-by-step explanation:

The mean absolute deviation (MAD) is a measure of variation of the average distance between each data value and mean of a data set. It describes  the variability of values with respect to mean of a given data set.

MAD can be determined by first calculating the mean of the data, find the sum of absolute value of the difference between each datum and the mean. Then divide this sum by the number of datum of the given data.

With Hui;s record and MAD for his data set, he would be able to describe the varations between the mean and each datum.
