Answer:
Mean = 137
Step-by-step explanation:
Add all the numbers- 320+190+45+120+30+90+115+200+140+120 = 1370
Divide the sum by the amount of numbers added- 1370/10 = 137
the mean is 137
you have to add up all of the number values that are listed ( 320,190,45,120,30,90,115,200,140,120) and divide by how many values that are there which is 10 so 1,370 divided by 10 is the mean (1,370/10=137)
c.126 red
red+green+yellow=350
10% out of 350 are yellow
0.1 times 350=35
350-35=315
3/5 out of 315 are green
red is not green so
2/5 of what is left is red
2/5 of 315 is red
2/5 times 315=430/5=126
126 red
