Answer:
85 percent
Step-by-step explanation:
68 out of 80 = 68/80
= 0.85, times 100
= 85 percent
First, find the probability of picking one 9. There are four nines in a deck of 52, so the probability is 4/52, which is 1/13.
The probability of picking a 9 the second time is 1/17, because if a 9 was picked the first time, then there are three 9s left and 51 cards left in total.
To find the probability of both events happening, multiply the individual probabilities together:
(1/13)(1/17)
The probability that both cards picked will be 9s is 1/221.
The coordinates of point r(-8,0).
<h3>What is midpoint formula in coordinate geometry?</h3>
The coordinates of the point r(x,y) which divides the line segment joining the points p(
,
) and q(
,
) internally in the ratio :
are
Given that,
Two end points on the line q(-14,0) and s(2,0). point r(x,y) is the partition of the line segment from q to s in a ratio 3:5
= 3 and = 5
By using the midpoint formula
Hence, The coordinates of point r(-8,0).

Answer:
(3x +2)(x +1)
Step-by-step explanation:
A number of different ways are suggested for doing this. One that seems straightforward is this.
For ax^2 +bx +c, look for factors of ac that total b. Here we have ...
ac = 3·2 = 6
b = 5
It is easy to see that the factors we just multiplied to get 6 are ones that total 5: 3+2 = 5.
Now, rewrite the "bx" term using this sum.
3x^2 +3x +2x +2
Factor each pair of terms.
3x(x +1) +2(x +1)
And factor out the common factor:
(3x +2)(x +1)
