The equation of the line shown in the graph is y = ?

The least value, first quartile, median, third quartile, and greatest value of the data are 4, 5, 8, 9.75 and 15 respectively.

The first step is to arrange the number in ascending order: 4, 5, 5, 6, 8, 8, 9, 10, 12, 15

The median is the number in the center of the data set. The number is 8.

First quartile = 1/4 x (n + 1) = 2.75 number : 5

Third quartile = 3/4 x (n + 1) = 8.75 = 9.75

Answer:

Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.

Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.

Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

Answer:

[tex]Mid(A) = 73[/tex]

[tex]IQR(B) = 8[/tex]

The difference of the medians of class A and class B is between  the interquartile range of either data set.

Step-by-step explanation:

Given

The attached box plots

To answer this, see attached image for how to read a box plot

With reference to the attached image of how to read the box plot;

Solving (a): The median of class A

[tex]Mid(A) = 73[/tex]

Solving (b): IQR of class B

IQR is calculated as:

[tex]IQR =Q_3 - Q_1[/tex]

From the box plot of class B, we have:

[tex]Q_3 = 87[/tex]

[tex]Q_1 = 79[/tex]

So, we have:

[tex]IQR(B) = 87 - 79[/tex]

[tex]IQR(B) = 8[/tex]

Solving (c):

[tex]Mid(A) = 73[/tex]

[tex]Mid(B) = 82[/tex]

[tex]IQR(B) = 8[/tex]

IQR of class A is calculated as:

[tex]IQR =Q_3 - Q_1[/tex]

From the box plot of class A, we have:

[tex]Q_3 = 76[/tex]

[tex]Q_1 = 68[/tex]

So, we have:

[tex]IQR(A) = 78 - 68[/tex]

[tex]IQR(A) = 10[/tex]

The difference (d) between the medians is:

[tex]d =Mid(B) - Mid(A)[/tex]

[tex]d = 82 - 73[/tex]

[tex]d = 9[/tex]

From [tex]smallest[/tex] to [tex]largest[/tex], we have: 8, 9, 10

i.e. IQR(B), d, IQR(A)

Step-by-step explanation:

Rational numbers are the type of numbers that can be written in fraction forms (1/b where a and b are integers and b ≠ 0). Rational numbers also include decimals that are repetitive (0.313131313131) and decimals that end (0.25).

The opposite are irrational numbers that cannot be written in fraction forms and that include decimals that do not end or repeat (0.249654296432926....).

Answer:

Integers.

Step-by-step explanation:

I'm assuming you are talking about number groups, such as integers, natural numbers, whole numbers, etc.

If so, then -15 belongs to the 'integers' group.

This is because consists of numbers that are not fractional components, such as -5, 5, 4, -4, -15, 15, 8, 91, 200, -200, etc. Basically, integers include only negative and positive numbers.

Natural numbers include positive integers only, such as 5, 15, 87, 100, 20, etc.

Whole numbers do not include negative numbers, fractions, or decimals. Examples of whole numbers include: 8, 16, 20, etc.

Therefore, -15 belongs to integers.

The mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column, which is correct option(A).

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Lori solved this multiplication problem.

29 × 31 = 699

The mistake Lori made when multiplying is that she didn't

We first construct the extended multiplication.

The result of multiplying 1 × 9 is 9.

The result of multiplying 1 × 2 is 2

After that, we multiply 3 × 9 to get 27. Since 27 is a two-digit number, we must carry the first digit, 2, to the following column.

Then we carry the digit of 2, which is 8, and multiply 3 × 2, which results in 6.

Finally, we get 899 by adding 870 and 29.

Hence, the mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column.

After answering the question provided, we can predict that the result will be as by equation As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.

A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.

A binomial distribution with the specified values of n and p has a mean of = np and a standard deviation of = sqrt(np(1-p)).

Inputting n = 261 and p = 1/5 results in:

μ = np = 261 × 1/5 = 52.2

5.28 is equal to sqrt(np(1-p)) = sqrt(261 1/5 4/5)

Calculating the minimal typical value of 2 is as follows:

μ − 2σ = 52.2 − 2 × 5.28 ≈ 41.64

The calculation for the maximum typical value + 2 is as follows:

μ + 2σ = 52.2 + 2 × 5.28 ≈ 62.76

These values are rounded to the nearest hundredth, giving us:

The range is 41.64 to 62.76.

As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.

Answer:

[tex]f(x) = \frac{2x}{5y+6}[/tex]

Step-by-step explanation:

Answer:

Below!

Step-by-step explanation:

f(x) = 2x/5x+6

Sub y for f(x) : y = 2x/5x+6

Swap x and y : x = 2y/5y+6

Multiply both sides by 5y+6 : 2y = (5y + 6) x

Distribute x : 2y = 5xy + 6x

Change sign : 2y - 5xy = 6x

Factor out y : (2-5x)y = 6x

Divide both sides by 2-5x : y = 6x/2-5x

Substitute for y : f^-1(x) = 6x/2-5x

Answer: f^-1(x) = 6x/2-5x

That's the best I could do with my current math knowledge, I hope it makes sense :)
