So what you would do is 8/5 + 4 x 7 = 26.9
then you round it to 30

Answer:
1.5
Step-by-step explanation:
The scale factor can be found by dividing the side length from triangle ABC by the corresponding side length from triangle ABC
so the scale factor would be equal to
12/8 and 9/6
9/6 = 1.5
12/8 =1.5
so we can conclude that the scale factor is 1.5
Answer:
A)Option D
B)P(X = 15) = 0.1325
Step-by-step explanation:
A) From the question, the information given follows binomial distribution because there are two mutually exclusive outcomes for each trial, there is a fixed number of trials. The outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial.
So option D is correct.
B) From the question, we are told that the poll reported that 66 percent of adults were satisfied with the job. Thus, probability is; p = 0.66
Let X be the number of adults satisfied with the job. Since 25 are selected,
Thus;
P(X = 15) = C(25, 15) * (0.66)^(15) * (1 - 0.66)^(25 - 15)
P(X = 15) = 3268760 × 0.00196407937 × 0.00002064378
P(X = 15) = 0.1325
