Mean=total/the number of values =>total=mean*the number of values
the total of the first set of 8 numbers is : total=8*8=64
the total of the second set of 12 numbers is: 12m
the total of the 20 numbers is: 64+12m
the mean of the 20 number is: (64+12m)/20=5
solve for m: 64+12m=100
12m=36
m=3
The mean goals scored by the soccer players this season is 18.3 goals
<h3>What is mean? </h3>
Mean is the ratio of the sum of data to the total sample of data.
If three soccer players are scored 25 goals this season., five soccer players scored 19 goals this season and ten soccer players scored 16 goals this season, the mean goal scored is expressed as:
Mean goal scored = 3(25)+5(19)+10(16)/3+5+10
Mean goal scored = 75 + 95+160/18
Mean goal scored = 330/18
- Mean goal scored = 18.3 goals
Hence the mean goals scored by the soccer players this season is 18.3 goals

Ive never seen a question lie this before
Since the first figure is a square I guess it stand for x^2
then we have -2x + 3x = x ( the 2 stets of rectangles)
and finally -3 + 1 = - 2
So i am presuming its x^2 + x - 2
Option b
Im not sure though
Answer:
<h2>A. x ≤2 or x>6</h2>
Step-by-step explanation:
2x+6 ≤ 10 or 2x + 8 > 20
⇔ 2x ≤ 4 or 2x > 12
⇔ x ≤ 2 or x > 6
