Can someone help me with this I need both area and perimeter

Answers

Answer 1

Answer:

Step-by-step explanation:

NO I FONY FEEL LIKE IT

Answer 2

Perminter= P

Area= A

How to calculate the P: the p of this shape is pretty much easy to solve. Finding a P of a shape, you need to add all the sides up. So you just need to add 9+6+2+5+5+5+2+6. Remeber to double check that you got all the sides. Anothor equation you can do is (6x2) + (5x3)+(2x2)+9. Just pick a equation to do and you get the answer

how to caculate the A: Caucalating the A of this shape is actually a little hard. There is two ways to solve this but the second way to me is kinda hard. The first way is two divide this shape into rectangles and squares. So I dived it like this ( look at the image below). To calculate the area of a rectangle is to mutiply lengh by width. So first I will need to multiply 9x6 to find the first area of the rectangle. Then I have to multiple 5x5 to find the area of the second square. Then I just have to add the answer of the first answer to the second answer is 54+25.

hope this helps!

During a school fundraiser, Dominic sold boxes of greeting cards for $7 each and earned a total of $364. Which equation could be used to find the number of boxes n Dominic sold?

Answers

By using simple multiplication, Dominic sold 52 boxes of greeting cards during the fundraiser.

What is multiplication?

Multiplication is an arithmetic operation that combines two or more numbers to find their product or the total number of objects in equal-sized groups. In multiplication, the numbers being multiplied are called factors, and the result is called the product.

The equation that could be used to find the number of boxes n Dominic sold is:

7n = 364

Where n represents the number of boxes Dominic sold and 7 is the price of each box.

To solve for n, we can divide both sides of the equation by 7:

n = 52

Therefore, Dominic sold 52 boxes of greeting cards during the fundraiser.

Answers

The variance of X, where X takes the values 28, 46, 73, and 73 with equal probability, is 364.5.

To find the variance of a random variable X, you need to follow these steps:
1. Calculate the mean (average) of X.
2. Calculate the squared difference between each value of X and the mean.
3. Calculate the expected value of the squared differences.
4. The result obtained in step 3 is the variance of X.
Let’s apply these steps to the given values of X: 28, 46, 73, and 73.
Step 1: Calculate the mean (average) of X.
Mean(X) = (28 + 46 + 73 + 73) / 4 = 220 / 4 = 55
Step 2: Calculate the squared difference between each value of X and the mean.
(28 – 55)^2 = 27^2 = 729
(46 – 55)^2 = 9^2 = 81
(73 – 55)^2 = 18^2 = 324
(73 – 55)^2 = 18^2 = 324
Step 3: Calculate the expected value of the squared differences.
Expected value = (729 + 81 + 324 + 324) / 4 = 1458 / 4 = 364.5
Step 4: The result obtained in step 3 is the variance of X.
Variance(X) = 364.5
Therefore, the variance of X, where X takes the values 28, 46, 73, and 73 with equal probability, is 364.5.

How many groups of tens would represent the value of the digit 4 in the number 14752?
A. 4
B. 40
C. 400
D. 4000
show me why

Answers

Answer:

C. 400

Step-by-step explanation:

The number 14752 is "Fourteen thousand, seven hundred and fifty two"

The 1 is the place of ten thousands ⇒ 10,000

The 4 is the place of thousands ⇒ 4,000

The 7 is the place of hundreds ⇒ 700

The 5 is the place of tens ⇒ 50

The 2 is the place of units ⇒ 2

So we need to find how many groups of tens are in 4000.

To do this, divide 4000 by 10.

To divide anything by 10, simply move the decimal point one place to the left.

Therefore, there are 400 groups of ten in 4000

as 400 × 10 = 4000

The angle measure from the ruler in this problem is given as follows:

63º.

How to obtain the angle measure?

The angle measure in the context of this problem is obtained using the ruler, which gives an angle measure between 0º and 180º, according to the arrow of the ruler.

The ruler is positioned between 60 and 70, three dots of the way, hence we apply the proportion to obtain the angle measure as follows:

60 + 3/10(70 - 60) = 63º.

What is probability in math?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Given:

12 students

3 groups consisting of 4 students.

Mark can't be in the first group.

The combination formula that I used is = n! / r!(n-r)!

where: n = number of choices ; r = number of people to be chosen.

This is the formula I used because the order is not important and repetition is not allowed.

Since Mark can't be considered in the first group, the value of n would be 11 instead of 12. value of r is 4.

numerator: n! = 11! = 39,916,800

denominator: r!(n-r)! = 4!(11-4)! = 4!*7! = 120,960

Combination = 39,916,800 / 120,960 = 330

Therefore, There are 330 ways that the instructor can choose 4 students for the first group.

When we're working with quantitative data, we use a histogram to show the distribution of the data. A histogram is a graph that shows the number of times that a certain value, or range of values, appears in a dataset.

A histogram is a type of graph that displays the distribution of data. The graph is made up of a series of rectangles (bars) of equal width. The height of each bar corresponds to the frequency of the data that falls within the class interval associated with that bar. It's important to note that histogram bars are contiguous.A histogram is used to display the distribution of continuous data. A histogram is a graph that shows the distribution of a continuous variable using a bar graph with bars representing the frequency of a range of values.

The amunt of money that college students spend on rent each month is usually between $300 and $600. However, there are a few students who spend $1,300. What measure of spread would be most appropriate to measure the amount of money that college student spend on rent per month? Explain in detail why or why not one of the below measures would be used.
A. Median
B. Range
C. Standard Deviation
D. Inquartile Range

Answers

The range would be the most appropriate measure of spread in this case because it takes into account the extreme values of $300 and $1,300 and provides a clear measure of the difference between them.

To measure the amount of money college students spend on rent per month, the most appropriate measure of spread would be the range. The range is the simplest measure of spread and is calculated by subtracting the lowest value from the highest value in a data set. In this case, the range would be $1,300 - $300 = $1,000.

The median would not be the best choice in this scenario because it only represents the middle value in a data set. It does not take into account extreme values like the $1,300 rent expense.

Standard deviation would not be the most appropriate measure of spread in this case because it calculates the average deviation of each data point from the mean. However, it may not accurately represent the spread when extreme values like the $1,300 rent expense are present.

The interquartile range (IQR) would not be the best choice either because it measures the spread of the middle 50% of the data set. It does not consider extreme values and would not accurately represent the range of rent expenses in this scenario.

In summary, the range would be the most appropriate measure of spread in this case because it takes into account the extreme values of $300 and $1,300 and provides a clear measure of the difference between them.

Find the perimeter of the picture frame,

p = Length(2) + Width(2)

p = 12(2) + 24(2)

p = 24 + 48

p = 72

72 > 36

over the past several years, a random sample of 40 women athletes at the school showed that 23 eventually graduated. does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? use a 1% level of significance.

Answers

The population proportion of women athletes who graduated from the university is more than 67%.

A random sample of 40 women athletes at the school showed that 23 eventually graduated.

n=40 , X=23 , p0 =67% = 0.67 , alpha = 1% = 0.01

H0: : p0 = 0.67 Vs H1 : p0 < 0.67

Test statistics = (p-p0) / (square root ((p0(1-p0) / n))

p=X/n

H0::p0=0.67 Vs H1:p0<0.67

Test statistics = z = (p-p0) / ( square root ((p0(1-p0)/n))

p=X/n=23/40

z = (0.575-0.67) / (square root (0.67(1-0.67)/40))=-1.278

P - value = P(z < -1.278) = 0.1007

Since the p-value is 0.1007 that is less than the level of significance the decision is to reject the null hypothesis. In conclusion, there is a sufficient evidence to support that the population proportion of women athletes who graduated is now more than 67%.
