The sample was 10 numbers.

4 of the numbers are less than 301.

So 4 out of 10 would be defective.

4/10 = 0.4 x 100 = 40%

He would expect 40% to be defective.

Answer:

A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of

change than Ryan's function indicating that Daniel can pack more boxes per hour.

Step-by-step explanation:

Given

Ryan: 3 boxes per hour

Daniel: y = 4h

Required

True statement about their functions

First, we calculate Ryan's function.

In 1 hour, he can pack 3 boxes.

In hours, he can pack 3h boxes.

So, the equation is:

y = 3h

So, we have:

y = 3h ---- Ryan

y = 4h --- Daniel

Both functions represent direct proportional functions.

So, when h increases y also increases.

<em>However, Daniel's function has a greater rate of change because</em>y = 4h<em> implies that he can pack 4 boxes per hour while Ryan can pack 3.</em>
