The histogram below shows information about the weights (in kg) of all the packages Colin needs to send out today for his business. What fraction of packages weigh less than 30kg?

Step-by-step explanation:

Given

See attachment for histogram

Required

Fraction less than 30 kg

First, we list out the packages and frequencies

The total frequency is:

The packages less than 30 kg are:

The total frequencies less than 30 kg are:

So, the fraction less than 30 kg is:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
