We are given the range of the data that is from 2.35 grams to 4.75 grams- we can call these two the lower and upper llimits respectively. In this case, to find the first class limits, we have to divide the range into 12. The range is 2.40 grams made up of 12 parts of 0.2 grams. The first class hence limits are
lower: 2.35 g
upper: 2.35+0.2 =2.55 g
Hey there,
#1 is D: 18 men and 30 women. The equation is: 12*m=48
#2 is B: Kathy drove 9 hours and Brain drove 3 hours. The equation is: 65m+55m/12=750
#3 is C: $0.86. The equation is: 2b+1h+1b+2h=8.52
#4 is B : 25 pizzas and 80 sodas. The equation is: 3*4p+5=260
