Answer:
0.213 is the required probability.
Step-by-step explanation:
We are given the following information:
We treat person booking from online travel website as a success.
P(Booking through online travel website) = 0.68
Then the number of people follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 15
P(exactly ten people out of fifteen people used an online travel website)
0.213 is the probability that exactly ten people out of fifteen people used an online travel website when they booked their hotel.
Answer:
B)
Step-by-step explanation:
The given expression is
It is 4th root. because 1/4 represents the 4th root.
So,
Therefore, the answer is B)
The answer is 16 3/8.
So, to find out the total weight we have to add them all up. However, since we need a common denominator to add them up, we have to change the denominator of the first two mixed fractions, 2 1/2 and 1 1/2. Since we know that 2 is a factor of 8, we know that we can use 8 as the common denominator. The third mixed fraction already has a denominator of 8 so we just have to change the denominator of, 2 1/2 and 1 1/2. To do this, we just have to multiply the numerator and denominator by 4 to get, 2 4/8 and 1 4/8. Next, we can add them all up. We first add the fraction part, 4/8 + 4/8 + 3/8, which would give us 11/8, which can be turned into 1 3/8. Finally, we just have to add the whole numbers and 1 3/8, 2 + 1 + 12 + 1 3/8, to get 16 3/8.
