Answer:

The median number of days absent is zero (0)

The mean number of days absent is 1.0 day

(b) The proportion of the population that has absenteeism greater than 4 days is 6.34 %

Step-by-step explanation:

total number of students, n = 284

The total number of students is even, the median number of days absent will in (n/2).

n/2 = 284/2 = 142

The cumulative frequency that falls in 148 students = 0 day

The median number of days absent is zero (0)

For mean:

Let the days absent = x

let the number of students = f

$mean (\bar x) = \frac{\sum fx}{\sum f}\\\\\bar x = \frac{(158\times 0)+ (64\times 1)+(18\times 2)+(22\times 3)+(4\times 4)+(5\times 7)+(6\times 8)+(9\times 2)+(13\times 1)}{284} \\\\\bar x = \frac{296}{284} \\\\\bar x = 1.0 \ day$

(b) the number of students with absenteeism greater than 4 dyas;

= 7 + 8 + 2 + 1

= 18

The proportion of these students;

$= \frac{18}{284} \\\\= 0.0634 \\\\= 6.34 \ \%$

The attached figures represent the transformations of the triangle ABC

<h3>How to draw the transformations</h3>

From the figure, the coordinates of the triangle ABC are:

A = (-2, 3)

B = (0, 2)

C = (3, 4)

Next, we carry out the required transformations on the above coordinates of the triangle ABC

<u>The rotation</u>

Here, we rotate the triangle 90 degrees clockwise across the origin

The rule of this transformation is:

(x, y) = (y, -x)

So, we have:

A' = (3, 2)

B' = (2, 0)

C' = (4, -3)

See figure (1) in the attachment for the graph of the rotation transformation

<u>The translation</u>

Here, we translate the triangle up by 3 units

The rule of this transformation is:

(x, y) = (x, y + 2)

So, we have:

A' = (-2, 5)

B' = (0, 4)

C' = (3, 6)

See figure (2) in the attachment for the graph of the reflection transformation

<u>The reflection</u>

Here, we reflect the triangle across the y-axis.

The rule of this transformation is:

(x, y) = (-x, y)

So, we have:

A' = (2, 3)

B' = (0, 2)

C' = (-3, 4)

See figure (3) in the attachment for the graph of the reflection transformation
