The dimensions of the rectangular garden to maximize the area is length = width = 75 meters.

Let l be the length and w be the width of the rectangular garden.

We need to find the dimensions of the rectangular garden of greatest area that can be fenced off (all four sides) with 300 meters of fencing.

The perimeter of the  rectangular garden = 300 meters

We know that the perimeter of the rectangle =2(length + width)

300 = 2(l + w)

l + w = 150               .......(1)

Now, the maximum area of a  rectangular garden is when Length  = width

So, for equation 1

l + l = 150

l = 75 meters

So, w = 75 meters

And the area of the rectangular garden = length * width

                                                               = 75 * 75

                                                               = 5625 m²

So the maximum area of the  rectangular garden is 5625 m²

Therefore, the dimensions of the garden to maximize the area is length = width = 75 meters and maximum area is  5625 m²

What is population?

The term "population" refers to all citizens who are either permanently residing in a nation or are only temporarily absent from it. This indicator displays the population of a given area on a regular basis. Growth rates are the yearly changes in population brought on by births, deaths, and net migration.

Given:

The CEO of a company wants to determine if taking the employees to a company retreat would boost their morale.

He decides to use a random number table to survey a simple random sample of 50 of the 250 employees.

As the population consist of 250 employees and simple random sample of size 50, to use a random number table to survey a sample random sample of 50 of the 250 employees, the population of employees should be labeled as 001-250.

Answer: 20/48

(simplified) 5/12

Step-by-step explanation:

We will use 6/8 - 2/6 for our example

6/8 - 2/6

Multiply the denominator on the right side by the denominator on the left side: 6x8 = 48

Make 48 the denominators on both sides: /48,  /48

Now multiply the denominator on the left side with the numerator on the  left side: 6x6 = 36

Make the first fraction's numerator 36: 36/48

Now multiply the denominator on the left side by the numerator on the right side: 8x2 = 16

Now make 16 the numerator of the second fraction: 16/48

Now that the denominators are the same, we can subtract!

36/48-16/48 = 20/48

Now to simplify:

divide 20/48 by 4 = 5/12

So the answer is 20/48 and when it is simplified it comes out to 5/12

This is how you subtract fractions with different denominators.

You can use the same method when adding, the only difference is that instead of adding in the last step, you add instead!

The equation of a line into slope is 1/2x+1

A method of formulating a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line crosses the y-axis is known as the y-intercept, and the slope refers to how steep the line is.

Y equals mx plus b is actually the slope intercept form. Because it provides both a slope and an intercept, the form is known as a slope intercept form.

A line's slope and y-intercept are expressed in the following formula: y=mx+b. The y-intercept, which is usually represented in coordinate form as (0,b), is the point where the line crosses the y-axis.

y=1/2x+1

8y-4x=8

Add 4x to both sides.

8y=4x+8

Divide 8 (the one with y) by both sides.

y=1/2x+1

Therefore the equation of a line into slope is 1/2x+1

12 bottles of soda cost  $15.84  next week

What is unit rate?

A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

Price of  5 bottles = $6

Price of  1 bottle = 6/5 = $1.2

10% of 1.2 = (10/100)*1.2 = 0.12

new price of 1 bottle = 1.2+ 0.12 = $1.32

What is compound interest?

Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.

Main body:

Given :

rate = 2%

amount = $1700

Total amount = $2200

Compounded monthly,

so formula becomes,

Total amount = amount (1+r/400)^4t

T = A[tex](1+r/400)^{4t[/tex]

2200 = 1700(1 +2/400)^4t

22/17 = (1 +1/200)^4t

22/17 = (1.005)^4t

1.29 = (1.005)^4t

a) The Test statistic of the hypothesis is; 0.23

b) The p-value from the test statistic is; 0.409

c) The final conclusion is there is not sufficient evidence to determine whether the antidepressant drug had an effect on changing working habits after one year.

Test statistic is defined as a number, calculated from a statistical test, used to find if your data could have occurred under the null hypothesis. In this case, we are dealing with proportions and as such the test statistic has the formula;

z = (p1 - p2)/standard error

p1 = 14/167 = 0.084; s1 = √(0.084 * 0.916/167) = 1.285

p2 = 316/833 = 0.38; s2 = √(0.38 * 0.62/833) = 0.0168

Hence, for the distribution of differences, the mean and the standard error are given as follows:

Mean: p = 0.38 - 0.084 = 0.296

Standard error: s = √(1.285² + 0.0168²) = 1.2854

a) Test statistic = p/s = 0.296/1.2854

Test statistic = 0.23

b) From p-value from z-score calculator, we get that;

p-value = 0.409

c) The p-value is greater than the significance value of 0.04, we fail to reject the null hypothesis and conclude that there is not sufficient evidence to determine whether the antidepressant drug had an effect on changing working habits after one year.

7.14 unit² is the area of the rectangle shown on the coordinate plane

The length and breadth of the rectangle multiplied together provide the area of the rectangle. To determine the area occupied by a rectangle within its perimeter, we compute the area of the rectangle.

Consider rectangle with vertices A(-1,-2), B(-3,-4), C(-6,-1) and D(-4,1). The area of the rectangle is:

Area = length × width

Now, find the length and the width:

Length (BC) = [tex]\sqrt{[-3-(-6)]^2 + [(-4)-(-1)]^2}[/tex]

or, BC = [tex]\sqrt{(3)^2 +(-3)^2}[/tex]

or, BC = [tex]\sqrt{18}[/tex] unit

Width (AB) = [tex]\sqrt{[(-1) -(-3)]^2 + [(-2)-(-4)]^2}[/tex]

or, AB = [tex]\sqrt{(2)^2 +(2)^2}[/tex]

or, AB = [tex]\sqrt{8}[/tex] unit

Then the area of the rectangle ABCD is

Area(ABCD) = length (BC) × width (AB)

Answer:

the average contribution to the political campaign was $0.12.

Step-by-step explanation:

To find the average contribution to the political campaign, we first need to convert the total amount of money contributed and the number of people who contributed to scientific notation.

The total amount of money contributed to the political campaign was $9.48 million, which can be written in scientific notation as $9.48 * 10^6.

The number of people who contributed to the campaign was 79 thousand, which can be written in scientific notation as 79 * 10^3.

To find the average contribution, we need to divide the total amount of money contributed by the number of people who contributed. Therefore, we can substitute the values in scientific notation into the formula to find the average contribution:

Average contribution = Total amount / Number of people

                   = 9.48 * 10^6 / 79 * 10^3

                   = 9.48 / 79

                   = 0.12

Therefore, the average contribution to the political campaign was $0.12.
