Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder
irakobra [83]

Answer:

Jude is not correct

Step-by-step explanation:

The volume of a square pyramid is given as:

V = a^2\frac{h}{3}

where a = base edge and h = height

Hence, the volume of the square pyramid with base edge of 7 in and height  of 7 in is:

V = 7^2*\frac{7}{3}

V = 114.3 in^3 ≅ 114 in^3

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius and h = height

Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

V = \pi *7^2*7

V = 1077.57 in^3 ≅ 1078 in^3

Since their volumes are not equal, Jude is not correct.

What is the standard deviation of the following test scores? Round your answer to the nearest hundredth. 82, 76, 93, 82, 73, 80
Juli2301 [7.4K]
First we find the mean (or the average)...
average : (82 + 76 + 93 + 82 + 73 + 80 / 6) = 486/6 = 81

now we subtract the average from every data point.....then square the result
82 - 81 = 1.......1^2 = 1
76 - 81 = -5....-5^2 = 25
93 - 81 = 12....12^2 = 144
82 - 81 = 1.......1^2 = 1
73 - 81 = -8.....-8^2 = 64
80 - 81 = -1.....-1^2 = 1

now we find the mean (or average) of those numbers
(1 + 25 + 144 + 1 + 64 + 1) / 6 = 236/6 = 39.33

that is ur variance....to find the standard deviation, take the square root of ur variance.....

square root 39.33 = 6.27 <==
