Given the box plot, will the mean or the median provide a better description of the center?
box plot with min at 10.5, Q1 at 11.5, median at 12.5, Q3 at 13.5, max at 15
The mean, because the data distribution is symmetrical
The mean, because the data distribution is skewed to the left
The median, because the data distribution is skewed to the left
The median, because the data distribution is skewed to the right
Answer:
The median, because the data distribution is skewed to the right
Step-by-step explanation:
Min= 10.5
Q1 = 11.5
Median = 12.5
Q3= 13.5
Maximum = 15
The data is skewed towards the right because more values towards the right side as compared to the left side.
For data to be symmetrical, it has same shape on both sides of the median, which in our case is not possible.
So, for skewed data we always prefer median because it is less affected by the outliers and if mean is chosen, the value of mean is biased towards the side that has larger values while median does not get affected by it. So, we choose median.
our correct option will be:
The median, because the data distribution is skewed to the right

How to solve this problem in math
Step-by-step explanation:
Well you got a good start. #16 = 105°, #17 = 27°, and #15 = 48°.
Inscribed angles are half the arc angle, so #3 = #10 = 21°, and #4 = #5 = 39°.
That means #14 = #12 = 120°, and #11 = #13 = 60°.
The sum of the angle arcs is 360°, and AD is the diameter, so it splits it in half. So arc BC is 180 - 78 - 42 = 60°, so #1 = 30°.
Therefore, #2 = 90°.
AG and FG are both radii, so AGF is an isosceles triangle. Therefore, #8 = #9 = 66°.
Similarly, FG and DG are both radii, so FGD is an isosceles triangle. So #6 = #7 = 24°.
That means #18 = 129°. So #20 = 129° and #19 = #21 = 51°.
That's all of them.
In the diagram below what is the relationship between the number of rectangles in the perimeter of the figure they form?
Answer:
the correct answer is the third one. (1, 16), (2, 20), (3, 24)
Step-by-step explanation:
A perimeter is a path that surrounds a two-dimensional shape.
In the first case, 1 rectangle, the perimeter is the sum of all the sides:
Perimeter = 6 + 2 + 6 + 2 = 16
In the second case, 2 rectangles, the perimeter is the sum of all external sides:
Perimeter = 6 + 2 + 2 + 6 + 2 + 2 = 20
In the third case, three rectangles, the perimeter is the sum of all external sides:
Perimeter = 6 + 2 + 2 + 2 + 6 + 2 + 2 + 2 = 24
In none of the cases, you take into consideration the interal sides. Just the external sides, so the correct answer is the third one.

What is the sum of 6 dm, 40 mm, 2 m, and 10 cm in meters?
Answer: 800
Step-by-step explanation:
Answer: 2.74 m
Step-by-step explanation:
You need to make the following conversions:
From 6 dm to m (Remember that [tex]1m=10dm[/tex]), then you get:[tex](6dm)(\frac{1m}{10m})=0.6m[/tex]
From 40 mm to m (Remember that [tex]1m=1,000mm[/tex]), then you get:

Giggles the clown gave every 10th child a balloon animal and paints every 3rd child’s face. If there are 105 kids at the party, how many kids will get balloon animals and have their faces painted?
it should be 31.5 kids get balloon animals
Answer:
Balloon Animals: 10 children
Face Paint: 35 children
Step-by-step explanation:
To find out how many children get balloon animals, divide 105 by 10. Your answer will be 10.5, but ten and a half children can't get balloon animals (it's physically impossible) so we would have to round down to 10. To find out how many children get their faces painted, you would divide 105 by 3, which would give you 35. So 35 children would get their faces painted.

which of the formulas would indicate that the graph h(x) was stretched in the horizontal direction by a factor of 3?
The correct answer to the question is option (2): [tex]\( h\left(\frac{x}{3}\right) \).[/tex]
To address the question about the horizontal stretching of the graph of a function [tex]\( f(x) \)[/tex] by a factor of 3, we need to understand how transformations affect the graph of a function. Here are the steps to determine the correct transformation:
1. Identify the Base Function: Recognize that the graph in question is of some function [tex]\( f(x) \)[/tex]. We don't need to know the form of \( f(x) \) to understand how it will be transformed.
2. Understand Horizontal Stretching: A horizontal stretch by a factor of [tex]\( a \)[/tex] is achieved by replacing every [tex]\( x \)[/tex] in the function with [tex]\( \frac{x}{a} \)[/tex]. In this case, [tex]\( a = 3 \).[/tex]
3. Apply the Stretch to the Function: Replace [tex]\( x \)[/tex] with [tex]\( \frac{x}{3} \)[/tex]in the function [tex]\( f(x) \).[/tex]
4. **Write Down the Transformed Function**: The new function after the horizontal stretch will be [tex]\( f\left(\frac{x}{3}\right) \).[/tex]
5. **Choose the Correct Answer**: Look for the choice that represents the transformation [tex]\( f\left(\frac{x}{3}\right) \).[/tex]
The correct transformation that indicates a horizontal stretch by a factor of 3 is:
[tex]\[ f\left(\frac{x}{3}\right) \][/tex]
This means that for any given value of [tex]\( x \)[/tex] in the original function, its corresponding point on the graph will now be three times further away from the y-axis, thus stretching the graph horizontally. If the original function had a point at [tex]\( (x, y) \)[/tex], the new function after the stretch will have a corresponding point at [tex]\( (3x, y) \)[/tex], which means the x-values have been stretched out.
Now, from the options given in the image:
1. [tex]\( h(3x) \)[/tex] represents a horizontal compression by a factor of 3, not a stretch.
2. [tex]\( h\left(\frac{x}{3}\right) \)[/tex] is the correct representation of a horizontal stretch by a factor of 3.
3. [tex]\( h(x) + 3 \)[/tex] represents a vertical shift upwards by 3 units.
4. [tex]\( 3h(x) \)[/tex] represents a vertical stretch by a factor of 3.
Therefore, the correct answer to the question is option (2): [tex]\( h\left(\frac{x}{3}\right) \).[/tex]

Then you do 413 men-371 women=42 more men then women.
Consider the function represented by the graph. What is the domain of this function? {x| x >}
Answer:
x | x ≥ 0 and x ≤ 8
Step-by-step explanation:
The domain of the function is defined as the possible x values that can be used in this function. Now, taking a look at the given graph, we would find that the line starts from x = 0 and continues taking x values till it reaches x = 0This means that for this function, we are allowed to use x values that are greater than or equal to zero and less than or equal to 8Therefore, the domain is any x value greater than or equal to zero and less than or equal to 8

Which graph best represents the solution to the system of equations shown below?
y = -4x + 19
y = 2x + 1
First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.
Rearrange equations
[tex]4x + y = 19[/tex]
[tex] - 2x + y = 1[/tex]
To cancel y, we must do equation 1 minus equation 2. Similarly:
[tex]4x - - 2x = 4x + 2x = 6x[/tex]
[tex]19 - 1 = 18[/tex]
[tex]6x = 18[/tex]
[tex]x = 18 \div 6 = 3[/tex]
So the x coordinate is 3.
The y coordinate can be found with substitution of x into one of the equations:
[tex]y = 2x + 1 = 2(3) + 1 = 7[/tex]
So where the two lines intersect is at the point (3, 7), which is the solution to the equations.
Answer:
The correct option is 2.
Step-by-step explanation:
The given system of equations is
[tex]y=-4x+19[/tex] ..... (1)
[tex]y=2x+1[/tex] ..... (2)
The slope intercept form of a line is
[tex]y=mx+b[/tex] .... (3)
where, m is slope and b is y-intercept.
From (1) and (3), we get
[tex]m=-4,b=19[/tex]
The slope of first line is -4 and the y-intercept is 19. It means it is a decreasing line and intersect the y-axis at (0,19).
From (2) and (3), we get
[tex]m=2,b=1[/tex]
The slope of first line is 2 and the y-intercept is 1. It means it is an increasing line and intersect the y-axis at (0,1).
Put y=0, to find the x-intercepts.
[tex]0=-4x+19\Rightarrow x=\frac{19}{4}=4.75[/tex]
[tex]0=2x+1\Rightarrow x=\frac{-1}{2}=-0.5[/tex]
Therefore the x-intercept of first line is 4.75 and the x-intercept of the second line is -0.5.
Only the second graph satisfy all the above condition.
One solving the given equation we get
[tex]-4x+19=2x+1[/tex]
[tex]19-1=2x+4x[/tex]
[tex]18=6x[/tex]
Divide both sides by 6.
[tex]3=x[/tex]
Put this value in equation (1).
[tex]y=-4(3)+19=-12+19=7[/tex]
Therefore the solution of the given system of equation is (3,7).
Hence the correct option is 2.
On average, seawater contains approximately 1.2 ounces of salt per liter.how many gallons of seawater to the nearest tenth of a gallon would contain 2.5 pounds of salt?
To find how many gallons of seawater contain 2.5 pounds of salt, convert the salt to ounces (40 ounces) and divide by the salinity concentration (1.2 ounces per liter) to get 33.33 liters. Then convert liters to gallons, resulting in approximately 8.8 gallons of seawater.
To solve this problem, we need to convert all units to be compatible and calculate the amount of seawater needed to obtain 2.5 pounds of salt based on the salinity given.
First, we convert 2.5 pounds of salt to ounces because the salinity is given as 1.2 ounces per liter. Since 1 pound is equal to 16 ounces, we have 2.5 pounds * 16 ounces/pound = 40 ounces of salt.
Next, we divide the total ounces of salt by the salinity concentration to find out how many liters of seawater we need:
40 ounces of salt / 1.2 ounces of salt per liter = 33.33 liters of seawater.
Then, we convert liters of seawater to gallons. There are approximately 3.785 liters in a gallon, so:
33.33 liters / 3.785 liters per gallon = 8.8 gallons
Therefore, to the nearest tenth of a gallon, it would take 8.8 gallons of seawater to contain 2.5 pounds of salt.

Heather received $100 for her 13th birthday if she saves it in a bank with 3% interest compounded quarterly how much money will she have in the bank by her 16th birthday
Answer:
109.38
Step-by-step explanation:
Recall the formula for compound interest is as follows:
A = P·(1 + r/n)nt , where
P = principal amount (initial amount deposited)
r = annual rate of interest (in decimal form)
t = # of years amount is deposited for
n = # of times interest is compounded per year
A = amount accumulated after t years, including interest
The problem asks how much money Heather will have in the bank by her 16th birthday when she deposited $100 on her 13th birthday in a bank with 3% interest compounded quarterly. From this, we have the following information:
P = $100
r = 0.03 ==> 3%/100% = 0.03
t = 3 years ==> 16 - 13 = 3
n = 4 ==> since there are 12 months per year and 12/4 = 3 months,
then interest is compounded every 3 months which is a total of 4 times per year
Therefore,
A = P(1 + r/n)nt
= 100(1 + 0.03/4)4·3
= 100(1 + 0.0075)12
= 100(1.0075)12
= 109.38069
≈ 109.38
Thus, Heather will have $109.38 in the bank by her 16th birthda
