Two experiments are conducted in which a single 6-sided die is rolled 20 and 80 times. The outcomes of the experiments are shown below. For each result calculate the experimental probability of rolling a ""2."" Express your answer as a reduced fraction and a decimal rounded to three decimal places. Data: 3 1’s, 3 2’s, 6 3’s, 1 4, 3 5’s, 4 6’s for the 20 times

Data for 80 times: 18 1’s, 12 2’s, 18 3’s, 6 4’s, 13 5’s, 12 6’s

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

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.
