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

Step-by-step explanation:
when you look at the graph, you look for where the peaks are. if the peak is not centered, it is skewed. in this case, it leans towards the left. hope this helps :)
Answer:
1/2
Step-by-step explanation:
theoretical probability of a coin flip is always 50% heads, 50% tails
15 minutes is one quarter of an hour, so the number of people accommodated in an hour would be 4 x 55 = 220 people per hour
