<h2>Area of rectangle is 10L-L²</h2>

Step-by-step explanation:

Let L be the length and W be the width.

Perimeter of rectangle = 2 ( L + W )

That is

           2 ( L + W ) = 20

               L + W = 10

                     W = 10 - L

We need to express the area of the rectangle as a function of the length of one of its sides.

           Area = Length x Width

              A = LW

               A = L(10 - L) = 10L-L²

Area of rectangle is 10L-L²

A picture is enlarged by keeping its width the same and increasing its length. The scatter plot shows the perimeter of the pictu
natima [27]
Since you have not included the plot, I'll just tell you how to find the function of the graph that you are looking for.
Function of the straight line has the general formula: y = mx + c
where: 
m is the slope of the line and c is the y-intercept

So first we will need to find the slope (m):
Taking two points from the graph (x1,y1) and (x2,y2), the slope can be calculated as follows:
m = (y2-y2) / (x2-x2)

Then, we will need to find the y intercept.
we have the equation y = mx + c and we have m calculated
Take any point that belongs to the line and substitute with the values of x,y and m and then calculate c.

Now you have both m and c calculated, just substitute with the values in the formula.

Box plots are used to display data using a rectangle whose vertical edges represent the quartiles.

<h3>(a) The annual salaries of both companies</h3>

From the box plots, we have the following highlights:

  • The entry salary at Company A is less than company B
  • The median salary at Company A is less than company B
  • The highest salary at Company A is greater than company B

<h3>(b) The pros and cons</h3>

For Company A, we have:

There is an outlier in the distribution of company A;

This implies that employees in company A have the possibility of earning more

For Company B, we have:

The entry salary at company B is more than the entry salary of employees in company A

75 percent of 88 is the same as 60 percent of what number?
tangare [24]
First we need to know 75% of 88.
To find this number we multiply 88 by 0.75. 
Hence, 0.75 * 88 = 66

Therefore, 60% of a certain number equals 66.
Then 1% of that certain number equals 66 / 60
Finally, to find our number (which equals 100%) we multiply by 100.
So 66 / 60 * 100 = 110.

Hence, 75 percent of 88 is the same as 60 percent of 110.
