Answer:
45.5
Step-by-step explanation:
To find the mean is to find the average number of the data set.
In order to do this you add up all of the numbers, then divide it by the value how many numbers are in the set.
40+58+37+23+66+42+35+37+51+42+56+37+61+52= 637/14=45.5
4,6 is what I think, see if you have a plain that has a90 deg around c.
Answer: Becky will have to spend £ 9.6 .
Step-by-step explanation:
The ratio of their ages will be:
Melissa : Becky : Daniel = 13 : 12 : 10
Total amount share = £42
Share of Becky = 
Hence, Becky's share = £14.4
Becky decided to save a third of her share.
Then, Amount she spend = 
hence, Becky will have to spend £ 9.6 .
The answer would be 150
To solve this do 50x30 and you would get 150
Answer:
x^2 + y^2 = 12
Step-by-step explanation:
For a circle with the center at the origin [(h,k) is (0,0)]
use the formula:
x^2 + y^2 = r^2
In this case r is 2sqroot3.
(2sqroot3)^2 is 12.
2•2•sqrt3•sqrt3
= 4•3
= 12
So we get,
x^2 + y^2 = 12
