Answer:
The standard deviation of the new data will be increased as compared to the previous standard deviation of the data.
Step-by-step explanation:
The prices are given to be : 59, 60, 65, 99, 175
Standard deviation = $49
Now, if we add or subtract any constant value to each of the terms then the standard deviation remains unchanged.
But, we add a new price in the given data that is $450

Hence, Standard deviation is calculated to be 139.5
Therefore, the standard deviation of the new data will be increased as compared to the previous standard deviation of the data.
Answer:
The rate of change for the given function is 6.
Step-by-step explanation:
Given function is:

The interval on which we have to find the rate of change is:
1≤x≤2
Here
a = 1
b = 2
We have to find the values of function on both points
Putting 1 in place of input (x)

Putting x = 2

The rate of change is calculated by using the following formula

Hence,
The rate of change for the given function is 6.

Answer:
18 ft
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
144 = 8w
Divide each side by 8
144/8 =w
18 =w
