17
Step-by-step explanation:
Variance=(standard deviation)^2
√289=standard deviation
Standard deviation=17
Answer:
(<u>fg)(x) = 12x³ + 12x²</u>
Step-by-step explanation:
Given f(x) = 3x + 6 and g(x) = 2x²
To find (fg)(x), we multiply g(x) with f(x)
(fg)(x)
(3x + 6) *( 2x²)
(3x) ( 2x²) + 6*2x²
6x³ + 12x²
hence (<u>fg)(x) = 6x³ + 12x²</u>
Answer:
Ratio of Boys : 28/53
Ratio of Girls : 25/53
Step-by-step explanation:
Girls : Boys
25 : 28
(Add them up) 25 + 28 = 53
53 = Total of both B & G
Hope this helps. :)
According to the question if we take one number as a M and 3 more than other represent m+3
so the equation will be : m+(m+3)=-13
2m+3=-13
2m=-16
m=-8(one number)
to get another number plug in -8 for m and that gives us -8+3=-5
prove if we pluged in all than we get the same result,-8-5=-13
that was the prove of that math hopefully you get it
ANSWER
Find out the how many cans does each one have.
To proof
As given
Amelia and Elliott are collecting empty soda cans for recycling
Amelia has 13 less than 5 times the cans that Elliott has.
let us assume that the Elliott has can be =x
Amelia can = 5x -13
Total can = 257 cans
than the equation becomes
x + 5x - 13 = 257
6x = 257 +13
6x = 270
x = 45
Elliott has can be = 45cans
Amelia can = 5 × 45 - 13
= 212cans
Hence proved
