Your answer is going to be A, B, and D :)
Answer:
well, its 10 for 4. so 8 is 20, 12 is 30, 16 is 40 20 is 50, and 24 is 1 hour, 2 tabels is half the time so 5 min... so it would take -1 hour and 5 min
Step-by-step explanation:
Answer:
34 because 50 percent of 68 is 34
Answer:
The probability that he answered neither of the problems correctly is 0.0625.
Step-by-step explanation:
We are given that a student ran out of time on a multiple-choice exam and randomly guess the answers for two problems each problem have four answer choices ABCD and only one correct answer.
Let X = <u><em>Number of problems correctly answered by a student</em></u>.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 2 problems
r = number of success = neither of the problems are correct
p = probability of success which in our question is probability that
a student answer correctly, i.e; p =
= 0.75.
So, X ~ Binom(n = 2, p = 0.75)
Now, the probability that he answered neither of the problems correctly is given by = P(X = 0)
P(X = 0) = 
= 
= <u>0.0625</u>
The most likely answer is vary greatly all year long. This is so, because of the different parts of the ocean, sometimes with higher temperatures, near the Florida keys, or in some waters in the gulf of Mexico, and colder waters, such as antarctic waters. Because of the weather changes, some parts of the ocean may freeze over, while some other parts are still free-flowing.
