Multiply the values across the rows. So you'll multiply each mark with its corresponding frequency
6*5 = 30
7*4 = 28
8*7 = 56
9*10 = 90
10*4 = 40
Then add up those results
30+28+56+90+40 = 244
Finally, you divide by 30 since this is the total number of scores (add up everything in the second column of the original table to get 30)
So we end up with the mean being 244/30 = 8.133 approximately
Round that value however you need to.
Answer:
29.6667%
Step-by-step explanation:
In first bag there is 15 M&M's ANd second bag has a total of 9 M&M's so that means there are a total of 24 M&M's.
In the first bag there is 5 blue M&M's and in the second bag there is a total of 2 blue M&M's so there is a total of 7 blue M&M's all together.
so there are 7/24 M&M's ( what were going to do it convert it into percents.
To do this were going to use these steps.
- were going to divided the number of blue M&M's by the total of M&M's all together so 7 divided by 24=?
- And then next we are going to multiply the result by 100 which=?
Calculations
7 divided by 24=0.291666.
Ok so now what is 0.291666 x 100=?
0.291666 x 100=29.6667 and there is our final answer.
Hope it helps have awesome day:)
