x = 5.5 % (rounded to nearest tenth) is the change in number of students from last year .

<h3>What is percentage ?</h3>

In mathematics, a percentage is a number or ratio spoken as a fraction of 100. It is often indicated by the percent sign '%', but the abbreviations 'pct.', 'pct', and 'pc' are also sometimes used. Percentages are dimensionless numbers. No units of measure

<h3>Calculation</h3>

825 + 8.25x = 870

8.25x = 870 - 825

x = 45/8.25

x = 5.454545454545455 %

x = 5.5 % (rounded to nearest tenth)

Refer to the following frequency distribution of days absent during a calendar year by employees of a manufacturing company:
adelina 88 [10]

Answer:

(a) 91 employees were absent fewer than six days.

(b) 22 employees were absent more than five days.

(c) 20 employees were absent from 6 up to 12 days.

Step-by-step explanation:

The data for the number of days absent during a calendar year by employees of a manufacturing company is given below.

(a)

The number of employees that were absent for fewer than six days is =

Frequency\  for\  class\ [0\ - \ 3]+Frequency\  for\  class\ [3\ - \ 6]\\=60 +31\\=91

Thus, there were 91 employees who were absent for fewer than six days.

(b)

The number of employees that were absent for more than 5 days is =

Frequency\  for\  class\ [6\ -\ 9]+Frequency\  for\  class\ [9\ -\12]+\\Frequency\ for\  class\ [12\ - \15]\\=14+6+2\\=22

Thus, there were 22 employees who were absent for more than 5 days.

(c)

The number of employees that were absent from 6 up to 12 days is =

Frequency\  for\  class\ [6\ -\ 9]+Frequency\  for\  class\ [9\ -\12]=14+6\\=20

Thus, there were 20 employees who were absent from 6 up to 12 days.
