Hello! Some assistance with this question would be really helpful (:

mode = 1 , median = 2 and mean = 3

Step-by-step explanation:

Here, we want to get the mean , median and the mode

1. Mode

The mode deals with the number which has the highest frequency. Looking at the table, the number with the highest frequency is 1

2. Median

The median deals with the middle number, given that the numbers were arranged from lowest to highest or highest to lowest. The count of frequency is 15 and this mean that the middle number is the 8th term.

With the given arrangement, The 8th term falls within the number 2

3. Mean

The mean is the average. The arithmetic mean is the sum of the numbers divided by their count

the sum of the numbers is;

1(7) + 2(3) + 3(1) + 5(2) + 8(1) + 11(1) = 45

The count of the numbers is the sum of the frequencies = 15

the mean is thus;

45/15 = 3

So therefore;

mean = 3

mode = 1

median =2

whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

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.
