Answer:

B. The probability that the student received a grade better than C is 0.45

Step-by-step explanation:

Total number of students:

15 + 30 + 35 + 16 + 4 = 100

<h3>Statements</h3>

p(<D) = 4/100 = 0.04
0.04 ≠ 0.2
Incorrect

p(>C) = (30 + 15)/100 = 45/100 = 0.45
0.45 = 0.45
Correct

p(not A or B) = (100 - 15 - 30)/100 = 55/100 = 0.55
0.55 ≠ 0.45
Incorrect

p(B or C) = (30 + 35)/100 = 65/100 = 0.65
0.65 ≠ 0.35
Incorrect

bob left work and traveled to school at an average speed of 25 mph. if it took bob 35 minutes to reach school, how far is bobs s

Alchen [17]

Rate x time = distance
25 x 35/60 = distance (35/60 is 35 minutes out of an hour- 60 minutes)
25/1 x 7/12 = distance (I put the 25 over 1 and reduced 35/60)
175/12 ≈ 14.58 miles

Notice that the time had to be in a fraction of an hour in order to do this.
