A set of dots plotted on a horizontal and vertical axis is known as a scatter plot. Because they can demonstrate the degree of connection, if any, between the values of observed quantities or events, scatter plots are crucial in statistics (called variables).
Explain about scatter plot?In an effort to demonstrate the degree to which one variable is influenced by another, scatter plots are used to plot data points on a horizontal and vertical axis. The values of the columns set on the X and Y axes determine the position of the marker that represents each row in the data table.
A scatter plot is a form of plot or mathematical diagram that uses Cartesian coordinates to display values for typically two variables for a collection of data. It is also known as a scatter graph, scatter chart, scatter gram, or scatter diagram.

James and lin got married and got new jobs. Lin earns $3100 more per year than James. Together they earn $82,000 How much does each of them earn per year?
Let
x ----> amount earned by James
y ----> amount earned by Lin
we have
x+y=82,000 -----> equation A
y=x+3,100 -----> equation B
solve the system
substitute equation B in equation A
x+(x+3,100)=82,000
2x+3,100=82,000
2x=82,000-3,100
2x=78,900
x=39,450
Find the value of y

The jeweler made 7 bracelets and 9 necklaces .
In the question ,
it is given that
amount of gold in each bracelet is [tex]=[/tex] 6 grams
amount of gold in each necklace is [tex]=[/tex] 24 grams .
let the number of bracelets [tex]=[/tex] "b" .
let the number of necklaces [tex]=[/tex] "n" .
since the total number of necklace and bracelet is 16 .
the equation is b + n = 16
so , b = 16 - n
also given that total gold used is 258 grams .
so the equation is 6b + 24n = 258
Substituting b= 16 - n in the equation ,
we get , 6*(16 - n) + 24n = 258
96 - 6n + 24n = 258
96 + 18n = 258
18n = 258 - 96
18n = 162
n = 162/18
n = 9
and b = 16 - 9 = 7

Write an equation for each line.9р87n3215689-9-8-2-6 -5 -3-2 -1 0-1-2-3-4-5m-6-7-8-9No
Answers:
line l: y = 4
line m: y = -2x + 4
line n: y = x - 1
line p: x = -4
Explanation:
To find the equation of a line we can use the following:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]Where (x1, y1) and (x2, y2) are two points in the line.
So, to find the equation for line l, we need to identify 2 points in the line. So, these points can be (1, 4) and (2, 4). So, replacing (x1, y1) by (1, 4) and (x2, y2) by (2, 4), we get that the equation of the line l is:
[tex]\begin{gathered} y-4=\frac{4-4}{2-1}(x-1) \\ y-4=\frac{0}{2}(x-1) \\ y-4=0(x-1) \\ y-4=0 \\ y=4 \end{gathered}[/tex]Therefore, the equation of line l is y = 4
In the same way, the equation of the black line m can be calculated replacing (x1, y1) by (2, 0) and (x2, y2) by (0, 4). So, the equation of the line m is:
[tex]\begin{gathered} y-0=\frac{4-0}{0-2}(x-2) \\ y=\frac{4}{-2}(x-2) \\ y=-2(x-2) \\ y=-2x+4 \end{gathered}[/tex]Therefore, the equation of line m is y = -2x + 4
So, the equation of the green line n can be calculated using the points (1, 0) and (3,2). Then, replacing (x1, y1) by (1, 0) and (x2, y2) by (3, 2), we get:
[tex]\begin{gathered} y-0=\frac{2-0}{3-1}(x-1) \\ y=\frac{2}{2}(x-1) \\ y=1(x-1) \\ y=x-1 \end{gathered}[/tex]Therefore, the equation of line n is y = x - 1
Finally, to calculate the equation of line p, we can't use the equation above, so we need to know that the vertical lines have equations with the form:
x = contact.
Since the vertical line is located at x = -4, the equation of the line p is x = -4

A flight from Toronto to Miami usually takes 3 hours and 5 minutes. Unfortunately, your plane takes off 45 minutes late. As your plane approaches Miami, it needs to circle the airport for another 12 minutes. How much longer than expected has your flight taken as a percentage?
The flight has taken 30.8 % longer as compared to the usual time.
Given that:-
Usual time taken by the flight from Toronto to Miami = 3 hours 5 minutes = 185 minutes
Time by which the plane is late for take off = 45 minutes
Time taken by plane to circle the airport = 12 minutes
We have to find by how much percentage the plane has taken more time as compared to the usual time.
Extra time taken by the flight = 45 minutes + 12 minutes = 57 minutes
Percentage by which the plane has taken more time as compared to the usual time = (57/185)*100 = 30.8 %

8x - 56 = 5x + 22
8x - 5x = 22 + 56
3x = 78
x = 78/3
x = 26
Note that:
mLM + mMN + mNP + mLP = 360° (sum of angles at a point)

I need to find the cost per table, the linear equation and the cost for making 15 tables
Explanation:
Let the cost of tables be C
Let the number of tables be"x"
If the cost of making 14 tables is $1,460 and the cost of making 17 tables is $1625, this can be expressed in the coordinate form of (C, x) to have two coordinates (14, 1460) and (17, 1625)
The general linear equation will be of the form C = mx + b
Get the rate of change "m"
[tex]\begin{gathered} m=\frac{C_2-C_1}{x_2-x_1} \\ m=\frac{1625-1460}{17-14} \\ m=\frac{165}{3} \\ m=55 \end{gathered}[/tex]Get the intercept "b" of the linear equation;
[tex]\begin{gathered} 1460=55(14)+b \\ 1460=770+b \\ b=1460-770 \\ b=690 \end{gathered}[/tex]Get the required linear equation:

[tex]\begin{gathered} C(1)=55(1)+690 \\ C(1)=745 \end{gathered}[/tex]Get the cost per for making 15 tables
[tex]\begin{gathered} C(15)=55(15)+690 \\ C(15)=825+690 \\ C(15)=\$1515 \end{gathered}[/tex]Hence the cost of making 15 tables is $1515

anna has 4 apples, rickelle has 302 apples, anna gave all her apples to rickelle, rickelle gave four apples to each homeless person, how many homeless people were given apples
Answer:
76 homeless people were given apples.
Step-by-step explanation:
Anna has 4 apples, all of which she gave to Rickelle.
Rickelle had 302 apples, and after Anna gave the 4 to her, she had 302 + 4 = 306 apples.
Rickelle gave four apples to each homeless person, how many homeless people were given apples?
This can be solved using a rule of three.
One person got 4 apples. How many people were given 306 apples.
1 person - 4 apples
x people - 306 apples
Applying cross multiplication
4x = 306
x = 306/4
x = 76.5
We cannot give apples to half a person, so we take only the whole number.
76 homeless people were given apples.
Iris claims that if we have two positive rational numbers, the one with the greater numerator is the greater. How do you respond?
If the denominators were the same for both fractions, then Iris would be correct.
Example: Compare 2/7 with 5/7
Since 2 < 5, this means 2/7 < 5/7
This works because a < b leads to a/c < b/c where c is some positive integer. The inequality sign doesn't flip when you divide both sides by a positive number. In the example above, I divided both sides by 7.
--------------------------
But what if we wanted to compare 2/7 with 5/1000?
2 < 5 is true but 2/7 < 5/1000 is not true.
We can use a calculator to get a decimal value for each fraction
2/7 = 0.2857 approximately5/1000 = 0.005We see that 2/7 is actually larger than 5/1000
Unfortunately the rule Iris came up with is incorrect.
If she mentioned the denominators being the same, then she would be correct. But overall in general, the claim is not correct.

Find all zeroes of h(x)=2x⁴-x³-18x²+9x
When you have a polynomial with no independent term you can start by factorizing the polynomial, as follows:
[tex]h(x)=2x^4-x^3-18x^2+9x[/tex]The common factor is x, then:
[tex]h(x)=x(2x^3-x^2-18x+9)[/tex]Now you have a third-degree polynomial inside the ( ), let's called it j(x):
[tex]j(x)=2x^3-x^2-18x+9[/tex]You need to factorize this polynomial, then find all the numbers that divide the independent term 9.
These numbers are:
[tex]1,-1,3,-3[/tex]Let's probe if any of these numbers makes j(x)=0:
[tex]\begin{gathered} j(1)=2(1)^3-(1)^2-18(1)+9 \\ j(1)=2-1-18+9_{} \\ j(1)=-8 \end{gathered}[/tex]Then 1 is not a root, let's try -1:
[tex]\begin{gathered} j(-1)=2(-1)^3-(-1)^2-18(-1)+9 \\ j(-1)=-2-1+18+9 \\ j(-1)=24 \end{gathered}[/tex]Then -1 is not a root, let's try 3:
[tex]\begin{gathered} j(3)=2(3)^3-(3)^2-18(3)+9 \\ j(3)=2\cdot27-9-18\cdot3+9 \\ j(3)=54-9-54+9 \\ j(3)=0 \end{gathered}[/tex]Then 3 is a root and you can apply synthetic division to find the others:
The new polynomial is:
[tex]2x^2+5x-3[/tex]Now you can factorize it as follows:
[tex]2x^2+5x-3=(2x-1)(x+3)[/tex]And finally, your 4th-grade polynomial can be written as:
[tex]h(x)=x(x-3)(2x-1)(x+3)[/tex]Thus, the zeros are at:
[tex]\begin{gathered} x=0 \\ (x-3)=0\text{ then x=3} \\ (2x-1)=0\text{ then x=1/2} \\ (x+3)=0\text{ then x=-3} \end{gathered}[/tex]The answer is 0, 3, 1/2 and -3
When value of y varies directly with x. When y = 3 1/3 , x = 1/3. What is the value of y when x is 2/3?
when y varies directly as x , the value of y when x = 2 / 3 is 6 2 / 3
How to find the value of y using direct variation?y varies directly with x.
Therefore,
y ∝ x
Hence,
y = kx
where
k = constant of proportionalitywhen
y = 3 1 / 3 = 10 / 3
x = 1 / 3
Therefore,
y = kx
10 / 3 = 1 / 3 × k
cross multiply
3k = 30
divide both sides by 3
k = 30 / 3
k = 10
Therefore, the value of y when x = 2 / 3 can be calculated as follows:
y = 10x
y = 10 × 2 / 3
y = 20 / 3 = 6 2 / 3

The heights of adult men in America are normally distributed, with a mean of 69.2 inches and a standard deviation of 2.66 inches. The heights of adult women in America are also normally distributed, but with a mean of 64.7 inches and a standard deviation of 2.54 inches.
The probability of women is more from its z score.
What is a Z score?
A score's connection to the mean within a group of scores is statistically measured by a Z-Score.A Z-score can show a trader whether a value is normal for a given data collection or not.For instance, a Z-score below 1.8 indicates that a business may be on the verge of bankruptcy, while a number closer to 3 indicates that a business is in good financial standing.95% of the time, a score from -1.96 & +1.96 standard deviation and variance out from the mean will be chosen at random.This is considered a statistically meaningful result if the probability of a raw score being chosen at random is less than 5%.For men:
m=69.2, s=2.66
when x=6 feet 3 inches = 75 inches
z score, z=x-m/s=75-69.2/2.66=2.18
P(z<2.18)=0.98537
For women:
m=64.7, s=2.54
when x= 5 feet 11 inches =71 inches
z score, z=x-m/s=71-64.7/2.54=2.48
