1) marbles altogether = 3+4=7
P(black) = 3/7
2) P(first black marble)= 3/7
second black marble - When you removed 1st one only 2 black marbles are left and altogether marbles that are left = 6
P(second black marble) = 2/6=1/3
P(2 black marbles without replacement) means black and black marbles without replacement.
P(2 black marbles without replacement) =3/7*1/3=1/7
3) P(first black marble)= 3/7
When you put that black marble back, you got again <span>3 black marbles and 4 red marbles in a bag. So,
</span> P(second black marble)= 3/7
P(2 black marbles with replacement)=3/7*3/7= 9/49<span>

The equation is 20(3) + 25(4) - 10 = $150, the 3 was given for lawns and the 4 was given for Gardens. Plug and Chug
It would moat likly be y=-2 due to it having to be perpendicular to the y axis and pass through the 5,-2 point
45/100 = 9/20
Work: divide by 5
Answer:
solve using long division.
75/4
what is the largest whole number smaller than 75 that 4 can go into?
72.
how many times can 4 go into 72?
18.
so then subtract 72 from 75 to get 3.
the new equation is
3/4
how many times can 3 go into 4?
0.75 times.
so add the 2 answers to get
18.75
4 can go into 75 18.75 times.
