He did not walk 1/2 a mile. Because it's a round-trip, it's technically 2 miles long. so, in the end, he did not walk 1/4 of the trip. Hope this helps :)
Answer:
<em>The width of the lid is 15 cm</em>
Step-by-step explanation:
<u>The Perimeter of a Rectangle</u>
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm
Is the answer to this question 88?
It will be a reflex angle
A reflex angle is an angle that is more than 180° and less than 360°
Obtuse: More than 90° but Less than 180°
Acute: Less than 90°
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%.
