D, because the Pythagorean theorem can only be used in the case of a right-angled triangle
Answer:
mean=28.8
median=31
Step-by-step explanation:
mean=sum of all values/number of all values
mean=40+45+7+21+31+40+45+7+21+31/10
=288/10
mean=28.8
Median
arrrange in order
7,7,21,21,31,31,40,40,45,45
in case of even ungrouped data median is the average of middle two values
= (31+31)/2
median =31
Answer:
around 1800 full rotations
Step-by-step explanation:
a circle is 360 degrees so if the bug was on it for 5 rotations then it would have traveled 360x5
30 x 30 = 900
This is the surface area of one side
900 x 6
Multiply by 6 to get the surface area of all 6 sides of the cube
900 x 6 = 5400
Answer:
It will take Kali 40 years to get his balance to $3,000.
Step-by-step explanation:
5% intrest of 1,000 is 50, that is the amount of money that he will get per year.
If you subtract 1,000 off of 3,000 it is 2,000, that is the money needed to get to 3,000 dollars on his bank account.
Kali gets $50 a year, and he needs $2,000 to get to $3,000.
If you divide 2,000 by 50, you will get 40. This is the amount of years needed to get his bank account up to $3,000 without further investments.
