Answer:
Step-by-step explanation:
Volume of a pyramid = 
Area of the rectangular base = Length × Width
= 8 × 6
= 48 mm²
Volume of the pyramid = 192 mm³
192 = 
h = 
h = 12 mm
Therefore, all the pyramids having height less than 12 mm will be fitted inside the given pyramid.
Height of the box(mm) Yes/No
10 Yes
13 No
8 Yes
For every cubic yard, it equals to 27 cubic feet.
So, could have this fraction
And we want to convert 3 cubic yards into cubic feet.
We can express 3 cubic yards as
Now multiply the
fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.
So, 3 cubic yards to equal to 81 cubic feet.
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%.
