What is the probability that the bus will arrive at Evie's stop after 8:20 a. m.?
Write your answer as a fraction in simplest form.

2/5 if you don’t include 8:20

3/4 if you include 8:20

Step-by-step explanation:

1. There are 20 times, and 8 times past 8:20, so it would be, 8/20 so simplified is, 2/5, (8 divided by 4, 20 divided by 4)

2. There are 20 different times, and 15 past 8:20 including 8:20, so it is 15/20, when simplified it is, 3/4, (15 divided by 5, over 20 divided by 5)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

a.

step-by-step explanation:
