The relationship that represents the given function is y = 0.6x + 208 and the graph is attached below.

The water level rises at the rate of 0.6 cm/min .

After 20 minutes the water level is 220 cm

let the initial water level be a.

∴ 220 = a + 0.6×20

or, 220 = a + 12

or, a = 208 cm

therefore the initial water level is at 208 cm.

Now we will find the relationship.

Let the water level is y and the level rises at the rate of 0.6 cm /min .

The require function will be :

y = 0.6x + 208

The graph of the function is attached .

The set of all pairings (x, f (x)) that singularly represent a function is known as the graph of both the function, which is a common technique for illuminating the function.

The function of the length 'x' in meters of the side parallel to the wall is A(x) = x/2(210 - x)

What are perimeter and area?

While area describes the space it occupies, perimeter describes how far the shape's edge extends. A shape's perimeter is its entire circumference. The region that an object's shape defines as its area.

Given, perimeter (P) = 210 meters ........... (i)

Let the length parallel to the wall be 'x' and the width be 'y'

So, the perimeter of the fence is

P = 2y + x ............... (ii)

From eq. (i) & (ii), we get

210 = 2y + x

or, y = 1/2(210 - x)

The area of the wall is calculated as:

A = xy

or, A = x * 1/2(210 - x)

or, A = x/2(210 - x)

Rewrite as

A(x) = x/2(210 - x)

Hence, the function of the length 'x' in meters of the side parallel to the wall is A(x) = x/2(210 - x)

The equation of the  circle , with diameter  DEis (x - 5)² + (y - 7)² = 80

An equation is an expression that appears as the relationship between two or more variables and numbers. since the  standard equation  for a circle  is (x - h)² + (y - k)² = r², where    (h, k)  is the center of the circle and r is the radius. It is given that the diameter of the circle is at D(-3, 3) and E(13, 11). So the coordinate of the center is:

h = (13 + (-3))/2 = 5

k = (3 + 11)/2 = 7

(h, k) = (5, 7) and the  Radius is diameter / 2 = 8√5 ÷ 2 = 4√5.

The correct answer is median.

The salary of 35 year olds would vary greatly, with significant variations. Undoubtedly, this type of data contains outliers. Because median is unaffected by outliers in the data set, it would be appropriate for the data that included outliers.

The observations are divided into two equal portions by the median. When observations are organised in order of magnitude, it reflects the middle value for the group of observations.

When data are input in ascending order, the median value is the middle value. In other words, the observation is in the middle.

If there are an even number of observations overall, the median is calculated as the average of the middle two observations.

The median is the middle observation in the arranged data if the total number of observations is an odd number.

You already got 4.2 averaged from 120 reviews. To get a 4.5 average, you need more 72 reviews with 5 ratings.

This problem can solved using average value approach.

Average value can be calculated using:

Average = sum of data value / number of data

Let p = number of required 5 ratings to get a 4.5 average.

Then,

sum of data value = 120 x 4.2 + p x 5

number of data = 120 + p

Hence,

Average = (120 x 4.2 + p x 5) / (120 + p)

4.5 = (504 + 5p) / (120 + p)

540 + 4.5p = 504 + 5p

Therefore, the national population growth rate in the United States in 2017 was 0.72%.

Growth rate is a metric for determining how quickly a variable has changed over time. It is usually represented as a percentage and is frequently used to calculate the rate of change in economic indicators such as GDP or the rate of inflation. Growth rate may also be used to quantify the rate of change in biological or population processes, such as the growth of an organism's population or the expansion of the size of a tumour. In general, a high growth rate is positive and indicates that a variable is increasing quickly, whereas a low growth rate is considered negative and suggests that a variable is increasing more slowly or may even be decreasing.

How to solve?

Population growth rate = (CBR - CDR + net migration rate) / 10

Population growth rate = (11.8 - 8.5 + 3.9) / 10

Population growth rate = (11.8 - 8.5) + 3.9 / 10

Population growth rate = 3.3 + 3.9 / 10

Population growth rate = 3.3 + 3.9

Population growth rate = 7.2 / 10
