A set of cards contains cards numbered 1-8. Mrs. Jacob's class is conducting an experiment in which a card is drawn from
the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the
theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?
111
125
143
250

Probability of 1000 trails= 1/8
1000=125
125

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
