Step-by-step explanation:
We need to find the median of:-
73 75 87 65 69 62 81 64 68 101 74 71 89 87
First, we need to arrange the numbers in ascending order as below:-
62, 64, 65, 68, 69, 71, 73, 74, 75, 81, 87, 87, 89, 101
Since there are a total of 14 numbers, let's split it up into two halves (each of seven numbers)
62, 64, 65, 68, 69, 71, 73 ||| 74, 75, 81, 87, 87, 89, 101
The median would be the mean of the two middle numbers i.e. the mean of 73 and 74
Median =
=
= 73.5
So, about half of the students spent less than 73.5 minutes doing homework and about half spent more than 73.5 minutes on homework
Answer: 4410
Step-by-step explanation:
To find the area of a square or rectangle, all you need to do is multiply the length times the width:
L × W = A
The lengh is 100, and the width is 50
100 × 50 = 5000
However, in this problem, we also have other shapes in the rectangle. To find the area of JUST the green, we need to subtract the areas of the two circles and small blue rectangle.
First, let's get the two circles over with. To find the area of a circle, use this formula:
A = π r is the radius, which in this case, is 6
A = π
A = 113 This isn't the exact answer, the exact answer would be 113.0973...
Now let's multiply the area of one of those circles by 2, since we have 2 circles:
113 × 2 = 226
Finally, we have to find the area of the blue rectangle. This is simple, just use the formula from the very beginning:
26 × 14 = 364
The last thing to do is to subtract the areas of the two circles and blue rectangle from the area of the entire thing:
5000 - (226 + 364) = 4410
