Attached is a picture of my answer.
The correct is b.
This is because, confidence interval is given by:
Confidence interval = p +/- error
In this case,
p = 18%
error = 3%
Therefore;
Confidence interval = 18+/-3 = [(18-3),(18+3)] = [15,21].
Therefore it will be true to say that the percentage of those who jog is between 15% and 21%.
Answer:
80in²
Step-by-step explanation:
Hey There!
So the first step of this problem is to find the width of the scale drawing
To do so we need to find the scale factor
To find the scale factor we divide the length of the room by the length of the scale factor
32/8=4
so the scale factor is 4
now to find the width
40/4=10
so the width of the scale drawing is 10 in
now we can find the area given the length and the width
10x8=80in²
so we can conclude that the area of the scale drawing is 80in²
Answer:
c, d, a, b.
Step-by-step explanation:
I'm presuming that the original equation is .
First, isolate c. You can do this by subtracting from both sides:
Next, simplify to .
Then, divide both sides by 7:
Finally, simplify to .
