Applied Statistics consists of 4 questions. Statistics show that there is a 78% chance that the student will answer to any one of Exam problems correctly. If the number of attempts for each question is unlimited, find the probabilities (First introduce X random variable, then state what is the distribution of X)
The student will correctly answer the first question after the 10th attempt
The student will correctly answer three questions after 10 total attempts
What is the average number and SD of attempts up to when the student answers all the questions correctly?

12*c

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
