Answer:
diameter = 24 yards
Step-by-step explanation:
C = π·d
75.36 = 3.14d
d = 75.36/3.14
d = 24
F(x) = 10 - 4x
You must know that f(x) is technically "y" (the right side of the ( not this place ,this place ) )
A) (2, -18)
f(x) = 10 - 4x
-18 = 10 - 4(2)
WRONG!!
B) (18, -2)
f(x) = 10 - 4x
-2 = 10 - 4(18)
WRONG!!
C) (-2, 18)
f(x) = 10 - 4x
18 = 10 - 4(-2)
18 = 10 + 8 (two negatives numbers multiplied together=positive number)
18 = 18
Correct!

Answer:
The median of the given data is 700.
Step-by-step explanation:
We are given the following data in the question:
400, 600, 800, 1000
Formula:
Median =
![\dfrac{2^{nd}+3^{rd}}{2} = \dfrac{600+800}{2} = 700](https://tex.z-dn.net/?f=%5Cdfrac%7B2%5E%7Bnd%7D%2B3%5E%7Brd%7D%7D%7B2%7D%20%3D%20%5Cdfrac%7B600%2B800%7D%7B2%7D%20%3D%20700)
Thus, the median of the given data is 700.

Let ŷ represent the profit (in thousands of dollars) for a certain company xx years after 1960. A statistician calculates a linear model
ŷ = -1.23 x + 16.07
Use the model to estimate the profit in 1965. Your answer should be in dollars, not thousands of dollars.
Answer:
![\=y =\$9.92](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%5C%249.92)
Step-by-step explanation:
From the question we are told that:
Number of years ![N=1960-1965=>5years](https://tex.z-dn.net/?f=N%3D1960-1965%3D%3E5years)
Linear model ![\=y = -1.23 x + 16.07](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%20-1.23%20x%20%2B%2016.07)
Therefore Inputting values into the model we have
![\=y = -1.23 (5) + 16.07](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%20-1.23%20%285%29%20%2B%2016.07)
![\=y = -6.15+ 16.07](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%20-6.15%2B%2016.07)
![\=y =\$9.92](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%5C%249.92)
