Answer:
f(x) = 5x + 350
Step-by-step explanation:
Create 2 points using the information given, where x is the number of pounds of coffee and y is the cost.
The 2 points are (100, 850) and (500, 2850)
Then, use rise over run to find the slope:
(y2 - y1) / (x2 - x1)
(2850 - 850) / (500 - 100)
2000 / 400
= 5
Then, plug in the slope and a point into y = mx + b to find b:
y = mx + b
850 = 5(100) + b
850 = 500 + b
350 = b
Plug in the slope and y intercept into y = mx + b to get the equation:
y = 5x + 350
Put it into function form:
f(x) = 5x + 350 is the cost function
Answer:
Option D, 58% of US residents agree with the health care proposal
Step-by-step explanation:
<u>Step 1: Identify the correct answer</u>
A statistic is a percent or ratio of a specific crowd for a desired purpose. Therefore, out of these options the one that makes the most sense to be a statistic of a sample would be Option D.
Answer: Option D, 58% of US residents agree with the health care proposal
we know that
-------> by supplementary angles
Solve for k
Combine like terms in the left side
Substract both sides
Divide by both sides
therefore
<u>the answer is the option </u>
