Answer:

159.75 m

Step-by-step explanation:

Formula for the area of a triangle:

A= \frac{(base)(height)}{2}

base = 15

height = 21.3

(15)(21.3) = 319.5

319.5 divided by 2 = 159.75 m

A​ state's recidivism rate is 17​%. This means about 17​% of released prisoners end up back in prison​ (within three​ years). Su
Bezzdna [24]

Answer:

a) 2.9%

b) Option B is correct.

The prisoners must be independent with regard to recidivism.

Step-by-step explanation:

Probability that one prisoner goes back to prison = 17% = 0.17

a) The probability that two prisoners released both go back to prison = 0.17 × 0.17 = 0.0289 = 2.89% = 2.9% to 1 d.p

b) The only assumption taken during the calculation is that probability of one of the prisoners going back to prison has no effect whatsoever in the probability that another prisoner goes back to prison. That is the probability that theses two events occur are totally independent of each other.

If they weren't, we wouldn't be able to use 0.17 as the probability that the other prisoner goes back to prison too.

A line that includes the point (2,7) has a slope of
liraira [26]

Answer:

y - 7 = -8(x-2)

Step-by-step explanation:

The point slope form is: y-y1=m(x-x1)

From the information that was given, we know our two points: (2,7)

From here, we can fill in some of the missing information: y-y1=m(x-x1) → y - 7 = m(x-2)

Now I can't tell if you wrote down -8 or just 8, but just in case my answer isn't the right number.

The answer would either be: y - 7 = -8(x-2)    [if you wrote down -8 as the slope]

OR

The answer would be: y - 7 = 8(x-2)    [if you wrote down 8 as the slope]
