Average = 77=(77+80+63+61+92+Next test)/6
Therefore, 77*6=77+80+63+61+92+Next test
Next test score = (77*6)- (77+80+63+61+92)= 89

A
Answer:
Gretchen because a 1/5 is bigger than 1/8 so 3/5 is bigger than 3/8
Answer:
c) 0.0871
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.

On a single day:
24 hours, so 
8:25 P.M. is 8:25 = 8.4167h
3:30 P. M. is the equivalent to 12 + 3:30 = 15:30 = 15.5h
Probability of rain between these times:

On both days:
Two days, each with a 0.2951 probability
0.2951*0.2951 = 0.0871
The correct answer is:
c) 0.0871
