The random numbers below represent 10 trials of a simulation. 2632, 1365, 9367, 2056, 0026, 6564, 1434, 8045, 4781, 8681 the numbers 0–7 represent students who watched television last night, and the numbers 8 and 9 represent students who did not. based on the simulated data, what is the probability that exactly 2 out of a group of 4 randomly selected seventh-graders watched television last night? a. 5 10 b. 4 10 c. 9 10 d. 1 10

  D.  1/10

Step-by-step explanation:

The trial results (# who watched TV) are ...

  4 4 3 4 4 4 4 3 3 2

Of the 10 trials, only 1 resulted in 2 in the group of 4 watching TV.

Your probability is 1/10.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
