The time students took to complete a statistics test is approximately normally distributed with a mean of 74 minutes and standard deviation of 8 minutes. For each question, sketch the normal curve, label the mean and SD, and shade the area of interest. Write your answer using correct probability notation, and find all appropriate 2- scores.

table 3 represents a direct variation function. : )

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

answer: - (a)

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :
