How do u write graphs in standard form?

Deffense [45]

Answer:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Given:

Coordinates of point A are (7,3).

Point B is on the x-axis whose abscissa is 11.

To find:

The distance between A and B.

Solution:

Point B is on the x-axis whose abscissa is 11. So, x-coordinate of the point B is 11 and y-coordinate is 0. It means, coordinates of point B are (11,0).

The distance between A(7,3) and B(11,0) is

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$D=\sqrt{(11-7)^2+(0-3)^2}$

$D=\sqrt{(4)^2+(-3)^2}$

$D=\sqrt{16+9}$

$D=\sqrt{25}$

$D=5$

Therefore, the distance between point A and B is 5 units.

Question 5 (4 points) Marijuana was recently legalized in Canada. A recent study reported that at low doses marijuana could have

Makovka662 [10]

Using the coefficient of variation, it is found that students were more variable in their marijuana consumption.

<h3>What is the coefficient of variation of a data-set?</h3>

The coefficient of variation of a data-set is given by the <u>division of the standard deviation of the data-set by the mean of the data-set</u>. The higher the coefficient, the more variable the data-set is.

In this problem, for marijuana consumption, the average was 3.74 and the standard deviation was 1.47, hence:

$CV_m = \frac{1.47}{3.74} = 0.393$

For depression levels, the average was 19.32 and the standard deviation was 3.18, hence:

$CV_d = \frac{3.18}{19.32} = 0.166$

Due to the higher coefficient, students were more variable in their marijuana consumption.
