Whatsapp is 500% in a fraction in the simplest form

Answers

500%=0.5 which is equal to 1/2 so the answer is 1/2

Actually the actually 500% as a fraction is 5/1 which equals 5.

I need help solving equations with variables on both sides. Please help and show me the work!x+3= -x-5

Answers

$x+3=-x+5\ \ \ \ | add\ x\ on\ both\ sides\n\n2x+3=5\ \ \ \ | subtract\ 3\n\n2x=-2\ \ \ | divide\ by\ 2\n\nx=-1$

Answer:

x=-4

Step-by-step explanation:

$x+3= -x-5\n+x -3=+x -3\n(2x)/(2) =(-8)/(2) \nx=-4$ First you combine like terms then you simplify after that you have your answer.

Find the slope of the parallel to each given line.1) y=2/3x-2
2)y=9/5x-5

Find the slope of a line perpendicular to each given line

1)y=-1/2x-2
2)y=-x-1

Answers

Slopes of parallel lines are same, only the y-intercepts are different

Slopes of perpendicular lines are opposite reciprocals, which means when they are multiplied, it equals to -1.

1)
Parallel lines have the same slopes
y=mx+b where m is the slope

so the slope of a parallel line would be 2/3

2)
y=9/5x -5
slope will be 9/5

Next set of questions:

1) y=-1/2x - 2

$-(1)/(2) * x = -1 \to x = 2$

So that means the slope is 2

2) y=-x-1
Slope is -1, and we need to find the slope for a line perpendicular to it.

$-1 * x = -1 \to x=1$

So the slope is 1

Which statement is true regarding the traits of scatterplots

Answers

Here are the choices

The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with positive correlation can have either weak correlation or strong correlation.

The slope of a line is independent of whether the correlation of a scatterplot has positive or negative correlation. A scatterplot with a negative slope can have either positive correlation or negative correlation.

The nonlinear association of a scatterplot depends on whether it has a weak or strong correlation. A scatterplot with nonlinear association will have a strong correlation.

The nonlinear association of a scatterplot depends on whether it has a positive or negative correlation. A scatterplot with nonlinear correlation will have a negative correlation.

It's a, because if it is positive, it can either be one skinny line, or one thick fat confusing line. Positive isn't perfect.

The statement first "The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative is true.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

The correlation between the two variables, the explanatory variable and response variable can have either a negative correlation or a positive correlation depending on the slope of the regression line.

When the dots are along the regression line we can say the correlation is strong.

If the dots are not along the regression line the correlation may have a weak correlation.

Thus, the statement first "The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with a positive correlation can have either a weak correlation or a strong correlation" is true.

Multiple Response: Please select all correct answers and click "submit." Which of the following are among the five basic postulates of Euclidean geometry? Check all that apply. A. A straightedge and compass can be used to create any figure. B. A straight line segment can be drawn between any two points. C. Any straight line segment can be extended indefinitely. D. The angles of a triangle always add up to 180.

Answers

To Euclid, a postulate is something that is so obvious it may be accepted without proof.

A. A straightedge and compass can be used to create any figure.

That's not Euclid, that's just goofy.

B. A straight line segment can be drawn between any two points.

That's Euclid's first postulate.

C. Any straight line segment can be extended indefinitely.

That's Euclid's second postulate.

D. The angles of a triangle always add up to 180.

That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."

What is the solution for x c=x+b

Answers

c = x+b

to solve for x

subtract b from each side

c-b = x+b-b

c-b = x

Answer: x = c-b

c = x+b

c-b= x therefore, x=c-b
