Find The 44th Percentile, P44, From The Following Data! Pls Help

Answers

Answer 1

Answer:

[tex] P_{44} = 29.9 [/tex]

Step-by-step Explanation:

The 44th percentile, [tex] P_{44} [/tex], of the given data can be calculated using the kth formula for percentile given as:

[tex] i = \frac{k}{100}(n + 1) [/tex]

where,

i = the ranking or the position of the percentile = ?

k = the percentile = 44

n = total number of the given data values = 23

Plug in the values into the formula to find "i"

[tex] i = \frac{44}{100}(23 + 1) [/tex]

[tex] i = \frac{44}{100}(24) [/tex]

[tex] i = \frac{1,056}{100} [/tex]

[tex] i = 10.56 [/tex]

Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.

Thus,

[tex] i_{down} = 10.56 = 10 [/tex]

[tex] i_{up} = 10.56 = 11 [/tex]

The data occupying the 10th position on the data set = 28.7

11th = 31.1

[tex] P_{44} = \frac{28.7 + 31.1}{2} = \frac{59.8}{2} [/tex]

[tex] P_{44} = 29.9 [/tex]

What is the point-slope form given the following slope and a point on the line? m = 3/7 , (7, -4)

Answers

Answer:

The equation is y = (3/7)x - 7.

Step-by-step explanation:

Given that the point slope form of an equation is y = mx + b where m represents the gradient and b is the y-intercept. Then, you have to substitute the following values into the equation :

[tex]y = mx + b[/tex]

[tex]let \: m = \frac{3}{7} ,x = 7,y = - 4[/tex]

[tex] - 4 = \frac{3}{7} (7) + b[/tex]

[tex] - 4 = 3 + b[/tex]

[tex] - 4 - 3 = b[/tex]

Answers

Answer:

Yes

Step-by-step explanation:

-27+(-3) can be simplified to -27-3

-27-3= -30

Answer: Yes you are correct. The answer is -30

Explanation:

We are adding 2 negatives. So we effectively add the positive versions of each number, and then make the result negative.

You can think of it in terms of money: you start off 27 dollars in debt and then borrow 3 more dollars to be a total of 27+3 = 30 dollars in debt.

Or you can think of it like you're under the ocean. Writing -27 could mean you're 27 feet below sea level. Adding on -3, ie subtracting 3, would then move you down 3 feet to get to 27+3 = 30 feet below sea level.

Answers

Answer:

The answer is 3.825 inches, the reduced picture will be 84% of the size of the original

Answer:

3.78 inches

Step-by-step explanation:

if the original length is 4.5 and we are making it 84 percent of that size we multiply 4.5 times 84 percent(that is 0.84).

If we type in 4.5 * 0.84 on a calculator the answer comes back as 3.78

A chemist has 42 grams of aluminum. There are for aluminum. How many milliliters of aluminum does the chemist have?

Answers

Answer:

4,200 g. of aluminum

Step-by-step explanation:

42x100=4,200

The 42 grams of aluminum implies that the chemist has 0.06429ml of aluminum

How to determine the amount of aluminum?

The mass is given as:

Mass = 42 grams

The density of aluminum is:

Density = 2.7 g/cm³

So, we have:

Volume = Density/Mass

This gives

Volume = 2.7/42

Evaluate

Volume = 0.06429cm³

Convert to ml

Volume = 0.06429ml

Hence, the chemist has 0.06429ml of aluminum

Timothy has three friends. The following table shows the distance and time it takes him to drive to each of his friends’ houses. 5 km 11 km 18 km to 10 min 15 min 20 min. Is the time it takes Timothy to drive to his friends’ houses proportional to the distance

Answers

Answer:

No

Step-by-step explanation:

The time it takes Timothy to drive to his friends' houses is not proportional. This is because when going to the first house, he is going at 4km per minute, but when visiting the second and third houses he is no longer traveling at that speed.

In a directly proportional relationship, increasing one variable will increase another. The given relationship is not proportional.

What is the directly proportional and inversely proportional relationship?

In a directly proportional relationship, increasing one variable will increase another.

This directly proportional relationship between p and q is written as

p∝q where that middle sign is the sign of proportionality.

Inversely proportional relationship increasing one variable will decrease the other variable if both are inversely proportional.

This directly proportional relationship between p and q is written as

p∝1/q where that middle sign is the sign of proportionality.

Given that the table shows the distance and time it takes him to drive to each of his friends’ houses.

Now, to know if the time it takes Timothy to drive to his friends’ houses proportional to the distance, find the ratio of distance to time for each row. Therefore, the ratios can be written as,

R₁ = 5km / 10 min = 0.5 km per min

R₂ = 11 km / 15 min = 0.7334 km per min

R₃ = 18 km / 20 min = 0.9 km per min

Since the ratio of distance and time in different cases is different, therefore, the given relationship is not proportional.

A scientist creates a colony of bacteria in a dish. This type of
bacteria duplicates itself per minute.
If at 9am the experiment started with a single cell and at 9:13
the dish was half-full, at what time will the dish be full?

Answers

Answer: 9:14

Step-by-step explanation: So if he started if 1 bacteria, it becomes 2 bacteria at 9:01, etc. So at 9:13, it is 2^13 and if that is half, that means 2^14 is when it is full so 9:14.

The dish will be full at  9:14 am.

Given, the bacteria duplicates itself per minute.

The experiment started with a single cell at 9 am and at 9:13 am the dish was half full.

So it is clear that after 13 minutes of experiment started the dish was half full.

Now, let here is only 1 bacteria in the dish which is duplicating per minute,so after 1 minute it becomes 2 after that it becomes 4 and after that it becomes 8. Hence it is clear from the example the bacteria doubles itself in powers of her minute. ([tex]2^x[/tex])  here x is the number of minute.

Since after 13 minutes the dish was half full, it means there are [tex]2^{13}[/tex] bacteria in the dish. hence the full dish is [tex]2^{14}[/tex] bacteria. so the bacteria will take 1 more minute for the dish to be full.

Hence at 9:14 am the dish was full.

what is the constant of the polynomial 2x3 - 8x2 + 3x - 7

Answers

Answer:

-7

Step-by-step explanation:

A constant number is a number that contains no variables like x and y. The only constant in that problem is -7.

A constant is a number which independent of anything and never changes thus the constant in the given expression 2x³ - 8x² + 3x - 7 is -7.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression,

2x³ - 8x² + 3x - 7

Here, x is a variable.

The constant multiplied by a variable is said to be the coefficient.

Thus, 2,-8,3 are the coefficient.

A number independent constant is -7 will be constant.

Identify the property of equality that makes Equation 1 and Equation 2 equivalent.

Equation 2
42x - 15 = 17x + 83

Answers

multiplicative property if equality. explanation: you’re just multiplying by 10.

We use the multiplicative property of equality to make Equation 1 and Equation 2 equivalent.

Given,

Equation 1 - 4.2x – 1.5 = 1.7x + 8.3

Equation 2 - 42x - 15 = 17x + 83

We have to Identify the property of equality that makes Equation 1 and Equation 2 equivalent.

We have,

Equation 1 - 4.2x – 1.5 = 1.7x + 8.3

Equation 2 - 42x - 15 = 17x + 83

If we multiply 10 on both sides of the equation, we get

10 (4.2x – 1.5)  = 10 (1.7x + 8.3)

10 x 4.2x - 10 x 1.5 = 10 x 1.7x + 10 x 8.3

42x - 15 = 17x + 8.3

We get,

42x - 15 = 17x + 8.3 which is equivalent to equation 2.

This property is called the multiplicative property of equality.

Thus we use the multiplicative property of equality to make Equation 1 and Equation 2 equivalent.

A refrigerator sells for $1201. If the sales tax rate is 6.8%, what is the total price that you would pay for the fridge?

Answers

The answer is $1282.66

Explanation:

The sales tax rate (in this case 6.8%) is paid as part of selling a product. Also, to find the final price of a product, find the tax rate (percentage) of the price of the product and add this number to the price. The process to know the final price of the fridge is shown below:

1. Determine the 6.8% of $1201

 1.1. Write the values

1201  = 100  

 x     =  6.8

 1.2. Cross multiply and solve the equation

x100 = 8166

x= 8166 ÷ 100

x = 81.66

2. Add this value to the original price

$1201 + $ 81.66 = $1282.66 (Total price including the sales tax)
