First to find the median we need to put the numbers in order from least to greatest.
62, 64, 65, 66, 67, 69, 83
Now take a number from each side
64, 65, 66, 67, 69
Once again.
65, 66, 67
On last time
66
So the median is 66.
Now to find the mean we must add all the numbers up
64+67+83+65+66+62+69
which equals 476
Now divide 476 by the total number of heights which is 7
476/7=68
So the mean is 68
Answers: Mean; 68 Median; 66
Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
On the first day of school last year, Cody was 148.5 cm tall.
Answer:
12. if 3/5 of them like chocolate ice cream 2/5 don't and 2/5 of 20 is 8.
A=8
13. 296 divided by 8 is 37
A=37
14. 123 divided by 7 is 17.5714285714 so each child will get 17 sweets and there will be 4 left over.
A=17 remainder of 4
15. umm i don't know just multiple 4.50 by the amount of soccer balls
