There are 12 red cards,17 blue cards,14 purple cards, and 7 yellow cards in a hat.

question 1: If a card is drawn from the hat and replaced 1,500 times. How many times is a yellow card drawn.

Question 2: In the second trial of 1,080 draws a purple card is drawn 324 times. how much greater is experimental probability than the theoretical probability probability?

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
