Answer:

<h2>In Grade 9, 18% of students liked running.</h2>

Step-by-step explanation:

Relative frequency is defined as the quotient between the absolute frequency and the total number of students.

In other words, the relative frequency is aimed to show the percentage representation of a data compared to the whole.

For example, according to the given table, in Grade 8, 17% of students liked swimming, it would be wrong to say that 17 students liked swimming, because relative frequency shows the percentage representation, that's it.

Having said that, the right answer is the last choice:<em> In Grade 9, 18% of students liked running</em>, because it's using properly the relative frequency.

You give 1/2 up a $46,000 salary to go back to school for 5 years. The total cost for going to school is $22,000. How much money
Ket [755]

The individual needs to earn $74,750 salary per year in order to recover the investment in 4 years.

What salary amount makes the individual as they were without a salary cut?

By the time the individual resumes back for work after 5 years, they need to earn their previous salary of $46,000 and recover the lost salaries, which is half of $46,000 lost in the last 5 years.

Total salaries lost=1/2*$46,000*5years

Total salaries lost=$115,000

Because the salaries lost needs to be recovered over 4 years, the extra earnings over and above the $46,000 in 4 years is the total salaries lost divided by 4 years

extra salary per year=$115,000/4

extra salary per year=$28,750

Total salary now=prior salary+ extra salary per year

Total salary now=$46,000+$28,750

Total salary now=$74,750
