Answer:
200,300,290,320,340
Step-by-step explanation:
If the mean of five numbers = 290
Then the total sum of the five numbers should be= 290*5
= 1450
an example of a set of five different numbers whose mean is 290
= 200,300,290,320,340
Summation of the above
=( 200+300+290+320+340)
= 1450
So the above set of numbers is a good example of a set of five different numbers whose mean is 290
Answer:
A
Step-by-step explanation:
-35 + 8 -27 (-27 is the depth
To simplify the ratio. You have to find both of these numbers Greatest common factor. Which happens to be 3 :P
So divide each number by 3
15 ÷ 3 = 5
---------------
3 ÷ 3 = 1
So this means our new simplified ratio is...
5 seconds to 1 minute.
Good Luck! :)
Answer:
-0.1 and 0.1
Step-by-step explanation:
A fourth root is a number which multiplied by itself 4 times gives 0.0001.
Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.
0.1*0.1*0.1*0.1 = 0.0001
So the real fourth roots are -0.1 and 0.1.
Answer:
volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
Step-by-step explanation:
The formula to find volume of sphere is:
Volume of sphere = 4/3 π r^3
if radius is divided by 2 i.e r/2
Volume of sphere if r/2 = 4/3 π (r/2)^3
= 4/3 π r^3/8
= (4/3 π r^3) / 8
= (Volume of sphere 1)/8
So, volume of sphere if radius is divided by 2 is 1/8 of volume of sphere with r radius.
