Answer:
The answer should be C. By combining like terms you can find the answer. 1.75a+2.75a = 4.5a
2.25b + 1.75b = 4b
2.25c + 1.25c = 3.5c

Answer:
The probability of getting someone in the 18-21 age bracket or someone who agreed to respond
Step-by-step explanation:
The counts are as follows
Age Group No of people contacted No of refusals Total
18-21 88 8 96
22-29 240 42 282
Total 328 50 378
The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is
Answer:
y = 2x - 1
Step-by-step explanation:
None of those would be correct, the line on the graph is y = 2x - 1 because the slope of the line is 2 and the y -intercept -1.
You can also check, we know that on the graph the coordinates where the dots are located are: (2,3),(3,5),(4,7) where the first number is x and second is y coordinate.
Check answer:
Let x=2 if this is correct y should be equal to 3 because of the first point (2,3).
y = 2(2)-1 = 4 - 1 = 3
check the other points if you want to confirm.
Y=-3/2x+4
The slope is -3/2, since Kerry traveled three feet and only went down 2.
The y intercept is 4, since she started four feet above the origin
