If the perimeter of the rectangle is 4646 centimeters and its length is 88 centimeters then its width would be 2235 centimeters

The perimeter of a form in geometry is defined as the entire length of its border. A shape's circumference is calculated by summing the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.

In daily life, people constantly employ the idea of perimeter. For instance, we measure the perimeter of the area to be fenced in or decorated for Christmas to determine how much wire you will need.

We are aware that a regular polygon has equal-length sides.

A regular polygon's perimeter is equal to the product of all of its sides, which is equal to the quantity o sides times the length of a side.

How to solve?

width = 4646 - 2*88 =4470

width of one side = 4470/2 = 2235 centimeters

Answer:

30x-18

Step-by-step explanation:

y=2x/3-2  is the required slope-intercept form of the line

The coordinate of points where the line intersects at the x-axis is (-3,0) and at the y-axis is (0,-2) now from there two points we can find slope if line that is

slope=y₂-y₁/x₂-x₁=(-2-0)/(0-(-3))

slope =-2/3

with one point (0,-2) and slope we can find the slope-intercept form that is y=mx+c

where m is slope and c is intercept on the y-axis

y=2x/3-2 this is the slope-intercept form and by simplifying it we get

3y=2x-6

The required are of shaded region for the given question is 20.7 cm^2.

A circle is partitioned into two areas, specifically the significant area, and the minor area. A bigger piece of the circle involved by the radii and the significant circular segment is supposed to be a significant area. A more modest part involved by two radii and a minor circular segment is known as the minor area.

We have,

∠BOC = 2π/5, radius = 6 cm, OA = 2 cm, DC = 2 cm

OD = 6 - 2 = 4 cm,

We know that

Area of triangle = OA×OD×sin(2π/5)/2

A = 2×4×0.475/2 = 1.9 sq. cm

And

Area of sector = (π/5)/2π ×πr^2

Area of sector = π(6)^2/5

Area of sector = 22.6  sq. cm

Area of shaded region = 22.6 - 1.9 = 20.7  sq. cm

Based on the information provided, it can be determined that there are 120 steps visible on the escalator at any given time.

Assume that there are x total steps, e for the escalator speed, and b for Bob's pace.

Bob noticed 75 stairs and climbed the entire escalator in the time it took him to ascend it. As a result, the escalator must have added an extra x + 75 steps.

Let e and b be the speeds of the escalator and Bob, respectively.

Alice took 150 steps at a speed of (3b-e) step rate as she descended the stairs.

Bob took 75 steps at a speed of (b+e) each step as he ascended.

Since, Al and Bob were walking the same distance at a time , we have,

150(3b-e) = 75(b+e)  

Solving  these two equation we get ,  e/b = 3/5

Thus while Bob took 75 steps to go up, the escalator contributed an extra

3/5 * 75 = 45 steps

Finally, there is a total of 75+45=120 steps in the length of the escalator.

Yes there was an error made and it is a type II error

What is type i and ii error in Hypotheses testing?

A Type I mistake in statistics is a false positive finding, whereas a Type II error is a false negative finding.

The possibility of making these mistakes is inherent in hypothesis testing since making a statistical choice always entails some level of uncertainty.

The significance level, or alpha (), determines the likelihood of a Type I mistake, whereas beta () determines the likelihood of a Type II error. These dangers can be reduced by carefully designing the layout of your study.

Comparison of Type I and Type II errors

Considering your minor symptoms, you decide to get checked for COVID-19. There are two mistakes that could happen:

False positives of type I are when a test indicates you have a coronavirus when you don't.

False negative type II errors occur when the test results indicate that you don't have coronavirus but in fact you have.

The null and alternate hypotheses are provided below for the scenario:

H0: The average amount of tooth whitening achieved by toothpaste is four shades.

Ha: The average amount of colors your teeth lighten after using toothpaste is less than four.

H0: µ = 4

Ha: µ < 4

While we reject the null hypothesis when it is true, we made a type I error, according to the definition.

The failure to reject the null hypothesis when the null hypothesis is false is what is referred to as a type II error .

In the hypothetical situation, it is said that the average number of shades that toothpaste whitens teeth is three. This implies,

There are less than four hues. This proves that the null hypothesis is untrue.

This indicates that when the null hypothesis is false, we are unable to reject it.

It is a type II error as a result.

When building a regression model provided the given information from the four remaining independent variables the variable to be entered next (second) would be variable with the highest coefficient of partial determination. (Option A)

A regression model refers to a function that illustrates the relationship between one or more independent variables and a response, target, dependent variable. The primary uses of regression analysis are forecasting, time series modeling and identifying the cause-and-effect relationship between variables. When building a regression model with five potential independent variables to explain the variation in the dependent variable, at step 1, variable x3 enters the regression model. Of the four remaining independent variables, the variable entered next into the model would be the variable with the highest coefficient of partial determination. A coefficient of partial determination refers to the measurement of marginal (extra) contribution of X variable or percentage of variation in the response variable that can be explained by the explanatory variables and can be used to measure how strongly two variables are related to one another.

Answer:

To get the correct answer.If it isnt followed you will get a number/answer but that is incorrect

There were 50 pounds of strawberries and 23 pounds of blueberries sold by Keilantra.

Given,

The cost of 1 pound of strawberry = 2.25

The cost of 1 pound of blueberry = 4

Total cost made by Keilantra = 204.50

The quantity of strawberry sold = x

The quantity of blueberry sold = y

Total quantity of berries sold = 73 pounds

We have to find the quantity of strawberries and blueberries sold:

Here,

2.25x + 4y = 204.50 and x + y = 73

Then,

x + y = 73

x = 73 - y

Substitute this in; 2.25x + 4y = 204.50

That is,

2.25 × (73 - y) + 4y = 204.50

(2.25 x 73) - 2.25y + 4y = 204.50

164.25 + 1.75y = 204.50

1.75y = 204.50 - 164.25

y = 40.25/1.75

y = 23

Then,

x + 23 = 73

x = 73 - 23 = 50

Therefore The quantity of strawberries and blueberries sold by Keilantra is 50 pounds and 23 pounds.

The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project-P-value = 0.251453

We are unable to reject the null hypothesis and accept it because the p value is higher than the significance level.

As a result, we draw the conclusion that the average tree-planting time is two hours.

Hypothesis:

In statistics, hypothesis testing is used to identify the variance in the group of data that results from genuine variation. Based on the presumptions, the sample data are taken from the population parameter. The hypothesis can be divided into many categories. A hypothesis is described in statistics as a formal statement that explains the relationship between two or more variables belonging to the specified population.

The exponential growth function's estimate of the monthly percentage rate is; log 3/ 3.

We will employ the exponential function, as indicated, to determine the monthly percentage rate;

P(t) = P(0)e∧(rt)

Enter the following parameters into the calculation to obtain the rate "r".

P(t) = P(0)e∧(rt)

3P(0) = P(0)e∧(rt)

3 = e∧(rt)

Taking log both sides.

log 3 = (rt)

r = log 3 / 3

r = 0.366

r = 36.6%

Consequently, the exponential growth function's estimate of the monthly percentage rate compounded continuously is; log 3/ 3.
