#2 is 62,000 because if you subtract 84,500 by 22,500 this will then equal 62,000
#3 then equals 9,000 because 37,100 subtracted by 28,100 equals 9,000.

How can you determine the coordinates of any image that is dilated with the center of dilation at the origin without graphing? E

julsineya [31]

Answer:

See explanation

Step-by-step explanation:

Let $(x,y)$ be the coordinates of the point which has to be dilated with the scale factor of $k$ with the center of dilation at point $(0,0)$ (the origin).

The dilation with the scale factor $k$ and the center of dilation at the origin has the rule

$(x,y)\rightarrow (kx,ky)$

So, you have simply to multiply each coordinate of the point by $k$ to get the image's coordinates.

Parallel line angles (transformation) prove it

Step2247 [10]

Transversal line :

A transversal line is one that crosses two or more lines at different points.

Transversal Properties :

Each pair of corresponding angles when a transversal cuts two parallel lines are equal in size.
Each pair of alternate interior angles created by a transversal when two parallel lines are cut are equal.
If two parallel lines are cut by a transversal, then each pair of interior angles on the same side of the transversal are supplementary, i.e. they add up to 180 degrees

Each pair of corresponding angles when a transversal intersects two parallel lines is equal. Thus,

∠1 = ∠6

∠4 = ∠8

∠2 = ∠5

∠3 = ∠7

Each alternate interior angle pair is equal if a transversal intersects two parallel lines.

∠4 = ∠5

∠3 = ∠6

Hence, proved..

Correlation coefficients can test ______ variable(s) at a time. a. two or more b. only one c. one or more d. only two

Vika [28.1K]

Correlation coeffiencients is used to determine the relationships between data, Correlation coefficients can test two or more variable(s) at a time

<h3 /><h3>What are correlation coefficients?</h3>

This is a linear correlation between sets of data. This coefficient can only be between -1 and 1.

Positive values show a positive correlation while a negative value shows negative correlation. A correlation coefficient of zero shows no relationship between variables.

Based on the explanation, we can conclude that Correlation coefficients can test two or more variable(s) at a time

The batting averages for seven baseball players are listed below. 0.176, 0.235, 0.272, 0.158, 0.201, 0.255, 0.303 What is the in

bonufazy [111]

Answer:

Interquartile Range= 0.079.

Step-by-step explanation:

Given,

The batting averages for seven baseball players are

0.176, 0.235, 0.272, 0.158, 0.201, 0.255, 0.303

First we have arrange the data in descending order or ascending order.

The ascending order of the data is

0.158, 0.176, 0.201, 0.235, 0.255, 0.272, 0.303

Median: The middle term of the data is the median of the data.

Here

Median = 0.235

First quartile: The median of the lower half of data.

The lower half of the data is 0.158, 0.176, 0.201

$Q_1=0.176$

Third quartile: The median of the upper half of data.

The upper half of the data is 0.201, 0.255, 0.303

$Q_3=0.255$

Interquartile: The difference between first quartile and third quartile.

Interquartile Range = $Q_3-Q_1$

=(0.255- 0.176)

=0.079

Find the coordinate of the midpoint of GH with endpoints G(-5,4) and H (-5,8)

Yuri [45]

Answer:

(-5,6)

Step-by-step explanation:

G(-5,4)=(x1,y1)

H(-5,8)=(x2, y2)

midpoint=?

now,

(x,y)= x1+x2/2 y1+y2/2

-5-5/2 4+8/2

-10/2 12/2

-5 6

therefore the co ordinates of midpoint are(-5,6)
