First find the price per calendar.
37.50/15=$2.5 per calendar

2450/2.5=980 calendars
A scale factor of 1.25, also written as 1 1/4 should be used
Answer: A. The difference in the sample size of the two groups makes a conclusion impossible.
The statement in letter A is very true. It is impossible to come up with a credible conclusion knowing the fact that the sample size for the two groups is not the same. The sample size affects the rate of the mean systolic blood pressure on both groups.
3 1/3 Ib = 10/3 lb
<span>10 1/2 dollars = 21/2 dollars </span>
<span>A: Cost of one lb of turkey = (21/2) / (10/3) = 3.15 dollars </span>
<span>2 1/2 lb = 5/2 lb </span>
<span>6 1/4 dollars = 25/4 dollars </span>
<span>B: Cost of one lb of turkey = (25/4) / (5/2) = 2.5 dollars </span>
<span>Therefore choice B is cheaper</span>
Answer:
The line will change its slope by a factor of -2 (line will now "point down" with twice the original steepness)
Step-by-step explanation:

(-1/2)f(x) = x
f(x) = -2x
