The dot plot shows the number of classes per semester that a group of boys and girls have chosen to take in their freshman year of college. Which statements correctly describe the two data sets?
The difference of the means is 1.5.
The difference of the means is 0.5.
The difference of the means is about one-third the mean absolute deviation of either data set.
The difference of the means is 1.
The difference of the means is about one-half the mean absolute deviation of either data set.
The correct statement is the difference of the means is 0.5.
What is Box- plot?A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary. A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.
Given:
As, from the box plot mean of boys is
= (1 x3 + 2x 7 + 3 x 6+ 4 x 2 + 5 + 6) /20
= 2.7
and, mean absolute deviation of boys
= (1.7 x 3 + 0.7 x 7 + 0.3 x 6 + 1.3 x 2 + 2.3 + 3.3)/ 20
= 1
now, from the box plot mean of girls is
= (1 x 2 + 2 x 4 + 3 x 7+ 4 x 4 + 1 x 5 + 6 x 2) /20
= 3.2
and, mean absolute deviation of girls
= (2.2 x 2+ 1.2 x 4 + 0.2 x 7+ 0.8 x 4 + 1.8 x 1+ 2.8x 2)/ 20
= 1.06

find the measure of UT answer choice - 65 51 70 55
Answer:
Option (4)
Step-by-step explanation:
If two chords intersect outside the circle, angle formed between the chords will be half of the sum of measures of intercepted arcs.
From the given picture,
[tex]m(\angle RQS)=\frac{1}{2}(m\hat{RS}+m\hat{UT})[/tex]
95° = [tex]\frac{1}{2}(135+m\hat{UT})[/tex]
190 = 135 + [tex]m(\hat{UT})[/tex]
[tex]m(\hat{UT})=190-135[/tex]
[tex]m(\hat{UT})[/tex] = 55°
Therefore, option (4) will be the correct option.

Answer: 11x-10y
Step-by-step explanation:
Combine like terms.
(5x+3y)-(2x-7y)+8x
3x + 8x
Remember to distribute the negative.
-(-7y) = +7y
3y +7y
Combine like terms once again.

What's the answer to this?
Answer:
steeper
Step-by-step explanation:
D) Vertically compressed
E) Flatter
=====================================================
Explanation:
An example would be if a = 0.5 which leads to the graph being half as tall as it used to be since 1/2 = 0.5; notice how a = 0.5 makes 0 < a < 1 true. Since the graph is squished vertically, the graph is flatter.
We don't have a reflection over the x axis since 'a' is not negative.
----------------
Extra info:
If a > 1 then the graph is stretched vertically to make it taller than it used to be. Eg: a = 5 leads to the graph being 5 times taller than before which also would make it steeper too. The value of d handles the vertical shifting. If d > 0, then we shift up d units. If d < 0, then we shift down |d| units.Find the value of in the triangle shown below.

The domains of the functions are "all real numbers", "all positive integers and zero", "all real numbers except 1 ≤ x ≤ 3", and " all real numbers except -3 ≤ x ≤ 1" respectively.
What is the domain of a function?A function's domain is the entire set of independent variable values.
The graphs of the functions are given.
Consider the first graph:
The graph of the function is defined for all values of x, therefore, the domain of the function is the set of "all real numbers".
For the second graph:
The graph of the function is defined for all positive integers and zero, therefore, the domain of the function is "all positive integers and zero".
For the third graph:
The graph of the function is defined for all real numbers except from x=1 to x=3, therefore, the domain of the function is " all real numbers except 1 ≤ x ≤ 3".
For the fourth graph:
The graph of the function is defined for all real numbers except x= -3 to x=1, therefore, the domain of the function is " all real numbers except
-3 ≤ x ≤ 1".
Hence, the domains of the functions are "all real numbers", "all positive integers and zero", " all real numbers except 1 ≤ x ≤ 3", and " all real numbers except -3 ≤ x ≤ 1" respectively.

A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
Given:
Amount saved in sale = $25
Sale price was 35% off the regular price.
To find:
The regular price of the tennis shoes.
Solution:
Let the regular price of the tennis shoes be x.
Sale price was 35% off the regular price.
[tex]Discount=\dfrac{35}{100}x[/tex]
Amount saved in sale = $25
[tex]0.35x=25[/tex]
Divide both sides by 0.35.
[tex]x=\dfrac{25}{0.35}[/tex]
[tex]x=71.42857[/tex]
[tex]x\approx 71.43[/tex]
Therefore, the regular price of the tennis shoes is $71.43.
Katniss Everdeen found the absolute value of |25| to be -25.
Do you agree? Yes or No
Explain:
Answer:
No
Step-by-step explanation:
Absolute values will never be negative.
Since absolute values are simply the number's distance from zero, it can never be negative, since there are no negative distances.
In this case, | 25 | is equal to 25. This is because the distance from 0 to 25 is 25.
So, Katniss is wrong.

Match the picture to the reason that would prove the triangles congruent.
Options:
NONE
ASA
SSS
SAS
AAS
HL
Answer:
Answer: SAS
Step-by-step explanation:
We must prove that triangles ABC and EDC are congruent.
Since BD bisects AE, then AC is congruent with CE.
Since AE bisects BD, then BC is congruent with CD
Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.
Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.
