Answer:
Based on what I see, it would be D.
Step-by-step explanation:
Because the x-side is +1 all the way down and the y-side is +5 for all.
So:
x-side (+1): 1+1 =2 / 2+1=3 / 3+1=4
y-side (+5): -5+5=0 / 0+5=5 / 5+5=10

Set up a proportion
1 lbs = 2 cups
x lbs = 1.5 cups
1/2 = x/1.5
1.5(1/2) = x
1.5/2 = x
.75 lbs = x
Out of 5 cards in the bag ...
-- There are 2 even numbers . . . 2 and 4 .
-- There are 3 odd numbers . . . 1, 3, and 5 .
So EITHER time, the probability of pulling an even number is 2/5 ,
and the probability of pulling an odd number is 3/5 .
The probability of pulling an even number the first time
AND an odd number the second time is
(2/5) x (3/5) = 6/25 = <em>24%</em> .
Hello :
2x²+16x-9 = 0
