Answer: f(2) + f(5) is 4.
Step-by-step explanation:
First input the values for x and solve for f(x) and then add their results.
f(2) = 2(2) -5
f(2) = 4 - 5
f(2) = -1
f(5) = 2(5) - 5
f(5) = 10 -5
f(5) = 5
Now add the results which is -1 and 5
-1 + 5 = 4
Answer:
84%
Step-by-step explanation:
The mean has 50% below the mean and 50 % above the mean
The mean is 103.47
The standard deviation is 4.07
Add the mean and the standard deviation
103.47+4.07 = 107.54
We want to know how much data is below the mean plus one standard deviation
Within one standard deviation is 68% , but that is on both sides, we are only needed on the right side so we need 1/2 of the 68 = 34
50+34 = 84
Answer:
$137.45
Step-by-step explanation:
First, we need to find the area of the circular rug in square feet.
Then we will multiply that with 1.75 to get total cost.
First,
Area of Circle = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Where r is the radius (which is half of diameter)
Given, diameter = 10 feet
Radius = 10/2 = 5 feet
Now, the area (A) :
![A=\pi r ^2\\A = \pi (5)^2\\A = 25\pi\\A= 78.54](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%20%5E2%5C%5CA%20%3D%20%5Cpi%20%285%29%5E2%5C%5CA%20%3D%2025%5Cpi%5C%5CA%3D%2078.54)
So, total cost would be:
78.54 * 1.75/sq ft = $137.45
The result you get when you divide is 11 + 16/x + 1
