There are 45 red tiles, 25 blue tiles, and 30 green tiles in a bag. A) Suppose you plan to conduct this experiment 60 times: – Draw a tile from the bag without looking. – Record the colour of the tile. – Replace the tile. How many tiles of each colour do you expect to get? B) Andrew conducted the experiment. He drew a blue tile 50 times. Did Andrew do something wrong? Explain.

40 minutes

step-by-step explanation:

add the time and multiply by 2

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
