Answer:
310
Step-by-step explanation:
total no.of students=1872
ratio of boys to girls=7:5
sum of ratio=total of students
12/12=1872
7/12=?
7/12*1872/1=1092which is the number of girls
1872-1092=780which is the number of boys
difference =1092-780= 310
Mean is the "meanest" because it requires the most work. Add up the values in your data set and divide by the number of terms in the data.
Let x represent attendees at Harry's Hoedown, then
Mean = ![\frac{Martha's (M) + Shirly's (S) + Harry's (x) }{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7BMartha%27s%20%28M%29%20%2B%20Shirly%27s%20%28S%29%20%20%2B%20Harry%27s%20%28x%29%20%7D%7B3%7D%20%20)
41 = ![\frac{48 + 33 + x}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B48%20%2B%2033%20%2B%20x%7D%7B3%7D%20%20)
123 = 48 + 33 + x
123 = 81 + x
42 = x
