Step-by-step explanation:
Find the mean, median, and mode(s) of the data with and without the outlier.
45, 52, 17, 57, 42, 54, 58
Answer:
Mean = 48.5, Median = 53, Mode = nothing, Outlier = 17
Step-by-step explanation:
Mean: Add all the numbers (388) then divide by how many numbers (8) are there. (= 48.5)
Median: Is the middle number () so you have to order them from least to greatest (17, 42, 45, 52, 54, 57, 58, 63) and then just keep marking them off left, right, left, right... until you get to the middle. But since there are two numbers (52, 54) you have to add them (106) then you divide by 2 (53).
Mode: Is the number that shows up the most. In this case none of them do.
Outlier: The number that is farthest from the other numbers (17).

Answer:
2(m + n)
Step-by-step explanation:
The words describe a quantity. "Twice" means two-times the previous amount. m and n are the unknown numbers that are being added, so you must put them in parentheses to indicate that they should be added first.
MATH!!! 15 points;))) find the surface area of the composite figure
please answer correctly and check over your work...
The area of a 2D form is the amount of space within its perimeter. The surface area of the composite figure is 76.8 ft².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The surface area of the composite figure,
Surface area = 2(3.6×2) + (4×2) + 3(3.6×4) + 2(5.6)
= 14.4 + 8 + 43.2 + 11.2
= 76.8
Hence, the surface area of the composite figure is 76.8 ft².

Answer:
First, break the shape into smaller shapes.
Bigger rectangle: 5m, 8m
Thin rectangle: 7m, 3m
Thinner rectangle: 8m, 2m
We will call the bigger rectangle B, the thin rectangle R, and the thinner rectangle r.
Step-by-step explanation:
B = 8 • 5 = 40
R = 7 • 3 = 21
r = 2 • 8 = 16
Add the areas together:
40 + 21 + 16 = 77
Therefore, the area is 77 meters.

The points (2, 8), (3, 9) and (4, 10) have a greater slope than the table
How to determine the points?The table and the graph that complete the question are added as an attachment
Start by calculating the slope of the table using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (22 - 11)/(10 - 5)
m = 2.2
Next, we calculate the slope of each point on the graph when connected to the origin using:
m = y/x
So, we have:
(2,8) ⇒ m = 8/2 = 4
(3,9) ⇒ m = 9/2 = 3
(4,10) ⇒ m = 10/4 = 2.5
(5,8) ⇒ m = 8/5 = 1.6
(6,7) ⇒ m = 7/6 = 1.2
(7,6) ⇒ m = 6/7 = 0.9
By comparing the slopes with 2.2, we can see that only points (2, 8), (3, 9) and (4, 10) have a greater slope than the table
Hence, the points are (2, 8), (3, 9) and (4, 10).

Parallel to y=−3/4x, through (4, -1)
Write the slope intercept form of each equation of the line. Use a fraction for slope if needed.
y = ___x + ___
Answer:
[tex]y=-\frac{3}{4}x+2[/tex]
Step-by-step explanation:
The slope-intercept form is given by y=mx+c, where m is the slope and c is the y-intercept.
Slope of given line= [tex]-\frac{3}{4}[/tex]
Parallel lines have the same slope. Thus, the slope of the line would also be [tex]-\frac{3}{4}[/tex].
[tex]y=-\frac{3}{4}x +c[/tex]
The value of c can be found by substituting a pair of coordinates.
When x= 4, y= -1,
[tex]-1=-\frac{3}{4} (4)+c[/tex]
-1= -3 +c
Add 3 to both sides:
c= -1 +3
c= 2
Thus, the equation of the line is [tex]\bf{y=-\frac{3}{4}x+2[/tex].

( yes, no ) the expressions (are, are not ) equal
Answer: No the expressions are not equal
Work Shown:
3² = 3*3 = 9

3⁵ = 3*3*3*3*3 = 243
The 3²+3³ = 36 doesn't match up with 3⁵ = 243
Therefore, the two expressions are not equal.

given the triangle below what is m<a, round to the nearest tenth?
The measure of angle A is 17.8
The correct option is (A)
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
As, perpendicular from B to side AC
In triangle BDC,
its angles are 30°, 60° and 90°
So, the sides ratio be 1 :√3 : 2
Now,
BD : DC : BC = 1 :√3 : 2
= 11√3/2 : 11/2 : 11
Now, using trigonometry
Sin A = P /H
Sin A = BD/AB
=(11/2)/18
= 11/36
= 0.3055
m<A = 17.79 ≈ 17.8°

Miguel and Lauren are testing two versions of a new video game. in Miguel's version he receives 25 points at the start of the game, plus one point for each level he completes. In Laurens version she receives 20 points at the start of the game, and 2 points for each level she completes. at what level will they have the same amount of points ?
Answer: 5 levels
Step-by-step explanation:
We will set up a system of equations and solve. Let x be the number of levels beaten, and let y be the number of total points.
Miguel's version:
y = 1x + 25
Lauren's version:
y = 2x + 20

[tex]f(x) = \left[\begin{array}{ccc}-2&-6 < x \le -1\\1&-1 < x \le 2 & \\5 & 2 < x \le 4\end{array}\right[/tex]
The question says that we plot two points in the domain -6 < x ≤ -2
The domain -6 < x ≤ -2 means that the values of x are greater than -6, but they do not exceed -1
The function at this interval means that all values of x have an output value of -2
So, the two points to plot could be (-5,-2) and (-1,-2)

What is the difference between the highest and lowest points in a data set?the mean the median the mode the range
Answer:
Range
Step-by-step explanation:
Range is found by subtracting the highest and lowest point in the dataset
Mode is the number that occurs most frequently in the set
Median is the central number in the dataset when arranged from lowest to highest
Mean is the sum of all the numbers in the dataset divided by how many numbers there are.
For example, take this list of numbers: 10, 10, 20, 40, 70.
The mean (also known as average) is found by: 10 + 10 + 20 + 40 + 70 / 5 = 30.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
