Answer:
The amount of tax is $14.37 and the tax rate percentage is 12.18%
Step-by-step explanation:
Find the amount of tax by finding the difference between the cost and selling price:
132.37 - 118
= 14.37
Find the tax rate percentage by dividing the tax by the original cost, and multiplying it by 100:
(14.37/118) x 100
= 12.18
The amount of tax is $14.37 and the tax rate percentage is 12.18%

You are given the results of measurement of resistors. We are testing the
measurement tool. It will pass the technical control if the mean value will be
in the range [198-202] with standard deviation less than 3 Ohms. Will the tool
pass the technical control?
Answer:
As both the standard deviation and the mean have the desired values, the tool passes the technical control.
Step-by-step explanation:
Mean:
The mean is the sum of all values divided by the number of values.
[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]
The mean is in the desired range.
Standard deviation:
The standard deviation is the square root of the sum of the difference squared between each value and the mean, divided by the number of values.
[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]
As both the standard deviation and the mean have the desired values, the tool passes the technical control.

A) Find the average value of the function over the given interval. (Round your answer to four decimal places.)
f(x) = 16 - x^2 , [-4, 4]
Answer: ???
B) Find all values of x in the interval for which the function equals its average value. (Enter your answers as a comma-separated list. Round your answers to four decimal places.)
Answer: x = ???
Answer:
(a) The average rate of change is 0
(b) The values of x are: [tex]x =4\ or\ x = -4[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 16 - x^2; [-4,4][/tex]
Solving (a): The average rate of change (m)
This is calculated using:
[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]
Where
[tex][a,b] = [-4,4][/tex]
So:
[tex]m = \frac{f(4) - f(-4)}{4 - -4}[/tex]
[tex]m = \frac{f(4) - f(-4)}{8}[/tex]
Solve f(4) and f(-4)
[tex]f(4) = 16 - (4^2) = 16 - 16 = 0[/tex]
[tex]f(-4) = 16 - (-4^2) = 16 - 16 = 0[/tex]
So:
[tex]m = \frac{f(4) - f(-4)}{8}[/tex]
[tex]m = \frac{0 - 0}{8}[/tex]
[tex]m = \frac{0}{8}[/tex]
[tex]m = 0[/tex]
Solving (b): All values of x where [tex]f(x) = m[/tex]
In (a), we have:
[tex]m = 0[/tex]
So:
[tex]f(x) = 0[/tex]
So, we have:
[tex]f(x) = 16 - x^2[/tex]
[tex]16 - x^2=0[/tex]
Express 16 as [tex]4^2[/tex]
[tex]4^2 - x^2=0[/tex]
Apply difference of two squares
[tex](4 - x)(4 + x) = 0[/tex]
Split
[tex]4 - x =0; 4 + x = 0[/tex]
Solve for x
[tex]x =4\ or\ x = -4[/tex]
We will find that the average of the function over the given interval is 0, and the two values of x such that the function is equal to the average are x = -4 and x = 4.
How to find the average of a function over an interval?
To find the average of a function f(x) over an interval [a, b] we need to compute:
[tex]\frac{f(b) - f(a)}{b -a}[/tex]
In this case we have:
f(x) = 16 - x^2
And the interval is:
[-4, 4]
We will get:
[tex]\frac{(16 - (4)^2) - (16 - (-4))^2}{4 - (-4)} = \frac{0}{8} = 0[/tex]
So the function has an average of 0 over that interval.
B) Here we just need to solve:
f(x) = 16 - x^2 = 0
We will get:
16 - x^2 = 0
16 = x^2
±√16 = x
±4 = x
So the solutions are x = 4 and x = -4.
