Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest

4 participants

Step-by-step explanation:

The name of the chart is "Participants PER race"

That means they tall you how many people did the race now all you gotta do is, Count up the numbers more than 61- So look at the 6 in the "stem" portion

it has 67, 67 they are both more than 61

Then look at the next "stem" number- 7

that has 74 which is more than 61 but less than 85

Then we look at the 8 in the "stem" it has three numbers- 84, 86, 89

but 86 and 89 are more than 85 so 84 is the only one which will go through

So the numbers are: 67, 67, 74, and 84

Thus 4 participants

I hope this explained it!

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.
