Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts if Ivan uses the same total number of yards for each
mixas84 [53]

Answer:

9 yards

Step-by-step explanation:

Let the length of each quilt be 'l'.

Given:

Length of green felt (g) = 15 yards

Length of blue felt (b) = 12 yards

Total number of quilts = 3

Now, the length of 3 quilts is given as:

Total\ length=l+l+l=3l ----- (1)

As per question:

Total length = Length of green felt + Length of blue felt

Total length = g+b

Total\ length=15+12=27--------- (2)

Now, comparing equations (1) and (2), we get:

3l=27\\\\l=\frac{27}{3}\\\\l=9\ yards

Hence, each quilt measures 9 yards in length.

We can from the graph that, the height of the bar that corresponds to the age group 9 to 12

= 14
and the height of the bar that corresponds to the age group 12 to 15

= 6


The sum of the two frequencies
