She can't spend more than 5 minutes on each of the remaining 8 questions.
It's a 60-minute test in which she has spent 20 minutes answering 12 questions. That means that there are 40 minutes remaining (60-20) to answer the remaining 8 questions. That's 40 divided by 8 = 5.
Just multiply ;
3×33.8 = 101.4 ounces !!

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Assuming the following questions:
a. exactly five
For this case we can use the probability mass function and we got:
b. at least one
For this case we want this probability:
And we can use the complement rule and we got:
And replacing we got:
c. between four and six, inclusive.
For this case we want this probability:
And adding we got:
The two integers are 7 and 5, 7*7=49, 5*5=25, 49-25=24
Answer:
720° :)
Step-by-step explanation:
You can find the total interior angle for any shape using the following (n being the number of sides):
S = ( n - 2 ) × 180 °
S = (6-2) * 180
S = 720
