A new car scanner has a 80% probability of correctly identifying a mechanical repair based on results of a customer questionnaire. Suppose that 20 random questionnaires are provided to the car scanner. Required:
a. What is the probability that exactly 8 repairs are correctly identified? Show how you calculate this value, e. g. calculator function or formula.
b. What is the probability of at most 8 repairs correctly identified?

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

just keep asking questions until you have a better understanding.
