You might want to find the IQR, but 23 will most likely be an outlier. Find the mean of all the points except 23 by summing all of the data and then dividing by the number of data points.

Basically add everything except 23 and then divide by seven, then compare that to the mean of all 8 points (which you get by adding everything including 23 and dividing by eight).

in abc the measure of angle a is 2x+3, the measure of b is 4x+2, the measure of c is 2x-1. What are the measures of the angles?

Mama L [17]

The measures of the angles in a triangle add up to 180°.
$2x+3+4x+2+2x-1=180 \\
8x+4=180 \ \ \ |-4 \\
8x=176 \ \ \ |\div 8 \\
x=22 \\ \\
2x+3=2 \times 22+3=44+3=47 \\
4x+2=4 \times 22+2=88+2=90 \\
2x-1=2 \times 22-1=44-1=43$

The measures of the angles are 43°, 47° and 90°.

Caleb and Mike both score the same amount of points in a game. Caleb has fifteen less than the total number of options. Mike has

zvonat [6]

Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.
