Determine if the following probability experiment represents a binomial experiment. If​ not, explain why. If the probability exp

eriment is a binomial​ experiment, state the number of​ trials, n.
An experimental drug is administered to 90 randomly selected​ individuals, with the number of individuals responding favorably recorded. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your answer.

A. ​Yes, because the experiment satisfies all the criteria for a binomial​ experiment, nequals nothing. ​(Type a whole​ number.)
B. ​No, because the experiment is not performed a fixed number of times.
C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
D. ​No, because there are more than two mutually exclusive outcomes for each trial.

Answer:

C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.

Step-by-step explanation:

Given that an experimental drug is administered to 90 randomly selected​ individuals, with the number of individuals responding favorably recorded.

We find here the no of trials are 90 but we cannot say the probability is the same for all trials.

In other words, each individual may have a different probability to respond.

Since p , the success for each trial may differ for each trial binomial cannot be accepted

C. ​No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.

The vertices of a figure are given. Find the coordinates of the figure after the transformations given. A(−5,3),B(−2,3),C(−2,1),
Tanzania [10]

Answer:

Reflection: A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

Dialation: A"(10, 6)

                B" (4, 6)

                C" (4, 2)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)

                D" (10, 2)          

Hoep this helps!!

Lamar borrowed S8000 at a rate of 13%, compounded quarterly. Assuming he makes no payments, how much will he owe after 10 years
LUCKY_DIMON [66]

The amount he needs to pay is $ 28753.61.

Step-by-step explanation:

Given,

Principal (P) = $ 8000

Time (T) = 10 years

Rate of interest (R) = 13%

The payment will be quarterly so, n = 4

To find the amount of compound interest.

Formula

Amount = P(1+\frac{R}{nX100} )^{nT}

Now,

Putting the values of P, T, n and R we get,

Amount = 8000(1+\frac{13}{4X100} )^{4X10}

= 28753.61 (approx)

What is the first year after 2018 that is a palindrome?
blondinia [14]
So a palindrome is a word or number that spells the same thing forwards and backward (e.g. tacocat, racecar, 101, 262) Palindrome years occur every 110 years (except at the end of the millennium, in which it is only 11 years). The last one happened in 2002, so the next one won't occur until 2112. Maybe some of us will live to see it!
