Answer: 11/20 = 55% and Grid A
Step-by-step explanation:
By doing 11/20 and making the denominator 20 into 100 by multiplying it by 5 we can get 55/100 which is 55%. And by simply counting the squares on the grid we can see 55 squares are shaded and the other 45 aren't showing its 55% shaded.
The y-intercept is the Y coordinate when X = 0
replace x with 0 and solve for Y:
y = 3/2(0)-5 = -5
The first point using the Y-intercept would be (0,-5)
Now to find another point replace X with another number other than 0 and solve for Y.
Lets use 2:
y = 3/2(2) - 5
y = 3-5 = -2
The second point would be (2,-2)
Now plot those two points and connect with a line.
See attached picture of how it should look:
There are 52 cards in a deck and half of them are black. Of the 26 black cards, half of them are spades while the other half are clubs.
So the probability is 13/26 or 50%
