Answer:
13 by 20 inches
Step-by-step explanation:
Represent the quantities as follows:
P = 2W + 2L
L = W + 7
Then P = 2W + 2(W + 7), or P = 4W + 14
and this formula has the value 66 inches.
Thus, P = 66 inches = 4W + 14 inches, or
52 inches = 4W
Dividing both sides by 4, we get W = 13 inches.
The width is 13 inches and the length is (13 + 7) inches, or 20 inches.
I believe the correct answer would be 150 pages

Answer:
B. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand
Step-by-step explanation:
The type I error is rejection of true null hypothesis.
In the given scenario our hypothesis are
Null hypothesis: The proportion of Americans that have seen a UFO is equal to 2 in a thousand.
Alternative hypothesis: The proportion of Americans that have seen a UFO is less than 2 in a thousand.
Type I error is the rejection of true null hypothesis so, in this case type I error is rejection of claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
