Solve:-

|-22| = ?

The absolute value of a number is always postie, whether it is a positive or negative number. It it is a positive number than the absolute value is that number, but if it is a negative number, it is the positive value of that number.

|-22| = 22

Examples:-

|38| = 38
|-5| = 5
|5| = 5
|-38| = 38

Find the indicated sum.

OlgaM077 [116]

Answer:

B. 70

Step-by-step explanation:

We have the sum given by $\sum_{i=1}^{5}(i+11)).$

Now, we open the summation by substituting the values of 'i',

i.e. $\sum_{i=1}^{5}(i+11)).$ = (1+11) + (2+11) + (3+11) +(4+11) +(5+11)

i.e. $\sum_{i=1}^{5}(i+11)).$ = 12 + 13 + 14 + 15 + 16

i.e. $\sum_{i=1}^{5}(i+11)).$ = 70.

Hence, the sum of $\sum_{i=1}^{5}(i+11)).$ is 70.

So, option B is correct.

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.
