Answer:

Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:

100 points<br><br> Use the line tool to graph the equation on the coordinate plane.<br><br> y=3/4x

Ad libitum [116K]

Answer:

The equation of line passes through the origin with slope m is given by:

$y=mx$

Given the equation:

$y = \frac{3}{4}x$

Slope = 3/4

y-intercept = 0

To Graph the equation on the coordinate plane.

Let us consider some values of x and y to make table.

x $y = \frac{3}{4}x$

0 0

2 1.5

4 3

6 4.5

8 6

10 7.5

Now, you can plot these points on the coordinate plane using line tool as shown below.

Determine the center and the diameter of the circle with the equation. x^2-6x+y^2+8y=24

Arisa [49]

Answer:

The center of the circle is (3, -4)

The diameter of the circle is 2

Step-by-step explanation:

The given equation of the circle is x² - 6·x + y² + 8·y = 24

The general form of the equation of a circle is x² + y² + 2·g·x + 2·f·y + c = 0

The center of the circle = (-g, -f)

The radius of the circle = √(g² + f² - c)

By comparing the given equation of the circle with the general form of the equation of a circle, we have;

2·g = -6, 2·f = 8, and c = 24

From 2·g = -6, we get;

∴ g = -6/2 = -3

g = -3

from 2·f = 8, we get;

∴ f = 8/2 = 4

f = 4

Therefore;

The center of the circle, (-g, -f) = (-(-3), -4) = (3, -4)

The center of the circle = (3, -4)

The radius of the circle, r = √(g² + f² - c) = √((-3)² + 4² - 24) = 1

The diameter of the circle, d = 2×r = 2 × 1 = 2

The diameter of the circle = 2.

The purpose of statistical inference is to make estimates or draw conclusions about a.

Svet_ta [14]

The purpose of statistical inference population based upon information obtained from the sample.

<h3>What is statistical inference?</h3>

statistical inference uses sample data to make estimates of or draw conclusions about one or more characteristics of a population.

The purpose of statistical inference is to estimate this sample to sample variation or uncertainty. Understanding how much our results may differ if we did the study again, or how uncertain our findings are, allows us to take this uncertainty into account when drawing conclusions. It allows us to provide a plausible range of values for the true value of something in the population, such as the mean, or size of an effect, and it allows us to make statements about whether our study provides evidence to reject a hypothesis.

We have four ideas for using the statistical inference.

1. Estimating uncertainty.

2. Confidence intervals.

3. Hypothesis tests.

4. Connections with other material.

What is the area of the parallelogram

Airida [17]

Answer:

24 square units

Step-by-step explanation:

For such questions it is convenient to choose the "base" to be a segment that is aligned with one of the coordinate axes. Here, the horizontal segments will serve. Their length is the difference between the x-coordinates of the end points, -2 -(-6) = 4, for example.

The height is measured perpendicular to the base, so will be the difference between the y-coordinates of the horizontal segments: 2 -(-4) = 6.

The area is given by the formula ...

A = bh

A = 4·6 = 24 . . . square units
