Step-by-step explanation:

m=(2-8)/(-5-5)=3/5

so y=(3/5)x+b.

substitute in (5,8),

8=(3/5)(5)+b

8=3+b

b=5

so y=(3/5)x+5.

There are 12 red marbles and 8 green marbles in a bag. What is the probability of selecting a red

madam [21]

Answer:

The probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag is 24/95

Step-by-step explanation:

Number of red marbles = 12

Number of green marbles = 8

Total number of marbles = 12+8 = 20

Probability of selecting red marble = $\frac{12}{20}$

Since it is the case of no replacement

Remaining marbles = 20-1 = 19

Number of red marbles = 12-1=11

Number of green marbles = 8

Probability of selecting green marble = $\frac{8}{19}$

So, the probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag = $\frac{12}{20} \times \frac{8}{19}=\frac{24}{95}$

Hence the probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag is 24/95

Ok so you know the first garden needs 1 and 2/5 bags of soil. Now first we need to find one fifth of that. So let's make this mied number into an improper fraction:

1 2/5 = 7/5

Ok now let's divide 7/5 by 5:

7/5 divided by 5/1 = 7/25

So Jared will need 7/25 bags of soil for his second garden, but we're STILL not done. now we have to add for the TOTAL.

1 2/5 + 7/25 > 7/5 + 7/25 > 7 x 5 = 35 > 35/25 + 7/25 = 42/25
_________
5x 5 = 25

Now let's simplify it to 1 and 17/25

Tom has a piece of rope that is 105 feet long. He wants to cut the rope into 5 equal pieces. How long will each piece be?

goblinko [34]

Hey there!

$\large\boxed{21 ft}$

If he is going to cut it into 5 equal pieces then we need to divide 105 by 5.

105 ÷ 5 = 21

So, each piece will be 21 feet long.

Hope this helps!
