For the sake of simplicity
obama = 66 mil
romney = 61 mil
66+61 = 127mil total votes
there are 66mil chances to pick an obama vote from 127mil -- 66/127
there are 61mil chance to pick a romney vote from 127 mil -- 61/127
see where im going with this?
Answer:
{-1, 5} (two real solutions).
Step-by-step explanation:
On the left side we want x^2, not x?
We need to rewrite x? = 4x - 5 in standard form, that is, as a quadratic with x terms in decreasing powers of x:
x^2 - 4x + 5 = 0
This factors easily to (x - 5)(x + 1) = 0.
We let each factor equal zero (0) separately and solve for x:
{-1, 5} (two real solutions).
Answer:
Looks like it's 1.
Step-by-step explanation:
Since it is a positive slope and it goes up 1 unit, the slope is 1.
Answer:
Option A. 
Step-by-step explanation:
we know that
The lateral area of a cone is equal to

we have


substitute and solve for l (slant height)

simplify


To get from 40% to 100%, divide by 2 and multiply by 5.
I.e. 40/2 = 20
20 x 5 = 100%
Do the exact same for 102
102/2 = 51
51 x 5 = 255 students
