For each probability and percentile problem, draw the picture. Let X ~ Exp(0.1).

decay rate =

μ =

Sketch a new graph, shade the area corresponding to P(X 7), and find the probability. (Round your answer to four decimal places.)

Sketch a new graph, shade the area corresponding to the 30th percentile, and find the value. (Round your answer to two decimal places.)

Find the average value of X. (Round your answer to two decimal places.)

2 x t divided by n

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
