The average time it takes an adults to complete a certain achievement test is 43.2 minutes, the standard deviation is 6 minutes. Use
the normalcdf feature on the calculator to find the probability that if 50
randomly selected adults take the test, the average completion time will be
less than 43 minutes. Give your answer as a percent rounded to two
decimal places (to the nearest hundredth).

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
