Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is 
The proportion that choose to vaccinate the teen boys is 
considering the first statement
The 95% confidence interval is 12% ± the margin of error*standard deviation is false because
The 95% confidence interval is is %12 ± the margin of error
considering the second statement
The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem
np = 64 * 0.12 = 7.68
and this value is less than 10 hence the confidence interval should not be calculated
considering the third statement
A 99% confidence interval will be smaller than the 90% confidence interval is false
This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval
Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where 
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get 
and solve to get 576 inches or 576/12 = 48 feet
Answer: Line of Symmetry means that there should be a line that makes both halfs of the shape, identical.
Step-by-step explanation:
If you draw a line on the girst parallelogram, then you see that the left side does not mirror the right side, thus not being symmetrical. The second shape that looks like a pentagon would by symmetrical and you wold draw the line right down the middle because then the left side would mirror the right side.
The other shape that would work would be the bottom left shape because if you draw a line of symmetry right down the middle of that shape, you can see that both sides are symmetrical and that the left side would mirror the right side.
Answer:
Step-by-step explanation:
As there is no other info given .
So we can choose any two ordered pairs whose mid point will come out to be (4,-10)
So we can one subtract a number from either x or y , and correspondingly add the same number to same variable again.
for example
we can add 2 to x and subtract 2 from x
So we get two ordered pairs as
(4-2 , -10) , (4+2, -10)
So
(2,-10) and (6,-10)
