Sample size, n = 1370
Proportion of adults who rated economy as good =
99% Confidence interval:
Putting the values, we get:
So since c= 30 u do 2 times 30 which is 60 then since d=8 u do 4 times 8 which equals 32 then add 60 and 32 which is 92 so the answer is
ANSWER: D.92
Answer:
440
Step-by-step explanation:
The pattern is add 3 each time.
To get to the 149th term from -4, you have to add 3, one hundred forty eight times.

-4+444=440
Rita's error is in the sign of 2.75 in her equation. If x is her selling price, Rita needs to find the value of x in
8(x -2.75) = 78
x = 2.75 +78/8 = 12.50
The answer is: {C]: "constant speed; 35 mi/h" .

Examine the graph provided; and examine the answer choices given.
When x = 1 ; (and the x-axis represent time in "h" (hours) ) ;
y = 35 (miles).
Even if you can't tell that it is EXACTLY 35 mi; it is closer to "35 mi" (after 1 hour); i.e "35 mi / h" than the other answer choices provided:
(i.e. "17.5 mi/ hr" ; and "70 mi./hr").
Furthermore, since the line is straight; we can determine that the speed is "constant" .
