A​ state's recidivism rate is ​22%. This means about ​22% of released prisoners end up back in prison​ (within three​ years). Su
storchak [24]

The probability that both of them go back to prison is 4.48%.

<h3>What is probability?</h3>
  • Probability is a measure of the likelihood of an event occurring.
  • Many events cannot be predicted with total certainty.
  • We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
  • The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

The state recidivism rate is given by 22%.

So, the probability that both of the prisoners will go back to prison will be:

  • = 22% × 22%
  • = 0.22 × 0.22
  • = 4.84%

Hence, the probability that both of them go back to prison is 4.48%.

11.Find the missing value given the rate of change.(2,6) and (x, 10) m = 4
Anvisha [2.4K]

The missing value x=3 is obtained by the concept of slope in coordinate geometry.

<h3>What is slope?</h3>

Positive or negative rates of change are both possible. Since the slope of a line is determined by the ratio of the vertical and horizontal change between any two locations on a plane or line, the slope is determined by the rise to run ratio. Where, Rise is the difference in elevation between two points. The horizontal shift between two places is known as a run.

Formula of slope = \frac{y2-y1}{x2-x1} (equation 1)

According to the question the coordinates are: xi=2, x2=x, y1=6, y2=10

Given, rate of change=4 (here rate of change=slope)

Putting all coordinates in equation 1

Slope= \frac{10-6}{x-2}

4=4/x-2

x-2=1

x=3

Therefore, the missing value x=3
