Answer:
Answer below
Step-by-step explanation:
3x+7 + 3x+6 + 3x = 3x + 3x +4x+2
x= 11
Since the scale is 1:83, the real airplane is 83 times longer than the model airplane.
real length = 10.5 in * 83 = 871.5 in
Now we convert 871.5 in into ft.
1 ft = 12 in, so 1 in = 1/12 ft
We divide the number of inches by 12 to find the number of feet.
871.5 in = 871.5/12 ft = 72.625 ft
Answer:
P = 66 ft
A = 216 sq ft
Step-by-step explanation:
Perimeter:
length + length + width + width
24 + 24 + 9 + 9 = 66
Area:
24 x 9 = 216
The probability that the next person will purchase exactly one costume is 67%.
<h3>How to calculate the probability?</h3>
Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.
53 visitors purchased no costume.
151 visitors purchased exactly one costume.
22 visitors purchased more than one costume.
Total visitor = 53 + 151 + 22
= 226
Probability that the next person will purchase exactly one costume will be:
= Those with one custome / Total visitors × 100
= 151 / 226 × 100
= 67%
The probability is 67%.
