Answer:

$13\frac{1}{3}\ in$

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produces similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

step 1

Find the scale factor

Let

z ----> the scale factor

$z=\frac{10}{6}$ ----> ratio of corresponding sides

simplify

$z=\frac{5}{3}$

step 2

Find the length of the enlarged design (L)

Multiply the length of the original design by the scale factor

$L=\frac{5}{3}(8)=\frac{40}{3}\ in$

Convert to mixed number

$\frac{40}{3}\ in=\frac{39}{3}+\frac{1}{3}=13\frac{1}{3}\ in$

A histogram is used to show the frequency of data, where the length of the bar represents the frequency.

50 students drank the recommended amount of water.

The recommended amount is given as:

$Amount \ge 48$

See attachment for histogram.

From the histogram, we have the following observations

The lengths of all bars of the histogram are less than 48, except one.

The length of the bar above 48 is 50.

This means that: 50 students drank the recommended amount of water.

Hence, the number of students is 50
