Find the median weight of 7 students from the following data: 32 kg , 40 kg , 35 kg , 42 kg , 30 kg, 45 kg , 37 kg Class : 7
Subject: optional mathematics

okok I know its easy​

37 kg

Step-by-step explanation:

Put the numbers in order from least to greatest

30, 32, 35, 37, 40, 42, 45

cross numbers out until you get to the middle number

30, 32, 35, 37, 40, 42, 45

32, 35, 37, 40, 42

35, 37, 40

37 kg

Explanation :

We know that, the median of an ungrouped data is the number in the middle of sequence when it is arranged ascending or depending and the number of terms is odd.

therfore , the sequence will be :

30kg , 32kg , 35kg , 37kg , 40kg , 42kg , 45kg

Here, 37 kg is the middle value i.e median of the given data .

hope it helps !!

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.
