Answer:

Option D - $\frac{1}{4}=\frac{x}{300}$

Step-by-step explanation:

Given : During the peak holiday season, a department store gift wrapper is expected to wrap a small gift box in 4 minutes.

To find : Which proportion could you use to find how many gifts can be wrapped at the same rate in 5 hours?

Solution :

We have given that,

In 4 minutes we wrap 1 box.

Let x be the number of gift wrap in 5 hours.

Convert 5 hours into minutes,

1 hour = 60 minute

5 hour = $5\times 60=300$ minute

i.e. In 300 minute we wrap x box.

The proportion defined the same rate is given by,

$\frac{1}{4}=\frac{x}{300}$

When we solve the proportion,

$x=\frac{300}{4}$

$x=75$

Therefore, Option D is correct.

The probability of writing a vowel is 0.5 (option b)

<h3>How to calculate the probability in this situation?</h3>

Probability is a way of measuring the certainty of occurrence of a specific event. Probability is measured from 1 to 0, with numbers closer to 1 referring to a higher chance and numbers closer to 0 referring to a lower chance.

According to the above, to calculate the probability we must perform the following operations:

Calculate how many vowels and how many consonants are there in total? In the series of letters there are 3 vowels and 3 consonants.
Later, we divide the number of vowels by the total number of letters to find the probability.
