The values that could represent this data set include 5, 6, 9, 10, 12, 10, 4, 6, and 19.
How to calculate the mean?It should be noted that a mean simply means the average of a set of numbers.
In this case, the values that could represent this data set include 5, 6, 9, 10, 12, 10, 4, 6, and 19. Therefore, the mean will be:
= (5 + 6 + 9 + 10 + 12 + 4 + 6 + 19)/9
= 81/9
= 9
When a 10th basketball player on this team scored 12 points in the last game, the new mean will be:
= (81 + 12)/10
= 93/10
= 9.3
Therefore, there's an increase in mean.

A cylindrical cup is 15 centimeters in height. When filled to the very top, it holds 450 cubic centimeters of water. What is the radius of the cup, rounded to the nearest tenth? Explain or show your reasoning.
Answer:
The radius of the cup is 3.1 cm.
Step-by-step explanation:
First, we the volume of a right cylinder is [tex]V = πr^{2} h[/tex].
V = volume of the cylinder[tex]π[/tex] = pir = radius of the cylinderh = height of the cylinderNow, using the information that was given to us, we can plug what we know into the equation: [tex]450=πr^{2}(15)[/tex].
From here, we simply solve for r by isolating it to find the radius. *Remember, what we do to one side we must do to the other.
Divide both sides by 15 to cancel it out on the right: [tex]30=πr^{2}[/tex]Divide both sides by pi to cancel it out on the right: [tex]9.549296586=r^{2}[/tex] (do not round until you have your final answer)Square root both sides to cancel out the exponent on the right: [tex]3.090193616=r[/tex]Round to the nearest tenth to get [tex]r=3.1[/tex]what is the median of, 50, 30, 40, 10, 20, 80, 60, 90, 10, 30, 110, 70?
Answer:
45
Step-by-step explanation:
median is the middle number after arranging a set of numbers in ascending or descending order.
let's arrange the set of numbers above in ascending order
10, 10, 20, 30, 30, 40 50, 60, 70, 80, 90, 110
since there are 12 digits in total, count out five digits starting from extreme left and also count out five digits starting from extreme right.
the two numbers left in the middle are 40 and 50.
median 40+50/2 = 90/2= 45

What is Pythagoras' Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
rhea got a new e-scooter. She wanted to show it to her friend on the way to the library.
Her friend Ronan's house is due north of her house.
After showing him the new scooter she went to the library which is due west from rocks house.
while returning back she drove 17km diagonally to her house.
By Pythagoras' theorem
|AC|^2 = |AB|^2 + |BC|^2
Here we can assume that
AB = The distance between rhea and her friend's house.
BC = The distance of the library from rocks house.
The triplet of the 17 would be (8, 15, 17)
So, we can say that the AB could be 8 km and BC could be 15 km or vice versa.

4.9t+0.3=5.6t+0.72 I need help on my work lol
The first step that we must take before attempting to solve the problem is to understand what the problem is asking us to do and what is given to us to help accomplish that goal. Although it does not explicitly state that we must solve for t, this is usually what the problem statement would be asking if we just receive and expression like this. What is given to us to accomplish that goal is the expression [tex]4.9t+0.3=5.6t+0.72[/tex].
Now that we have completed that step, we can move onto the next part which is actually solving the problem. The next step that we should take when solving for the unknown, in this case t, is to subtract 4.9t from both sides.
Subtract 4.9t from both sides
[tex]4.9t+0.3=5.6t+0.72[/tex][tex](4.9t-4.9t)+0.3=(5.6t-4.9t)+0.72[/tex][tex]0.3=(5.6t-4.9t)+0.72[/tex][tex]0.3=(0.7t)+0.72[/tex]Now that we got all of the t's to one side, let us isolate t completely and the next step that we should take is to subtract 0.72 from both sides.
Subtract 0.72 from both sides
[tex]0.3=0.7t+0.72[/tex][tex]0.3 - 0.72=0.7t+0.72 - 0.72[/tex][tex]0.3 - 0.72=0.7t[/tex][tex]-0.42=0.7t[/tex]The final step that we need to take to isolate t would be to divide both sides by 0.7 which would remove the coefficient from the unknown variable t and divide 0.7 from -0.42
Divide both sides by 0.7
[tex]-0.42=0.7t[/tex][tex]\frac{-0.42}{0.7}=\frac{0.7t}{0.7}[/tex][tex]\frac{-0.42}{0.7}=t[/tex][tex]-0.6=t[/tex]Therefore, after fully narrowing down the solution we were able to determine that the solution of the unknown variable or t is equal to -0.6

The mathematical expression that Katherine requires to know the price of the objects that she is going to buy is 8 * ($20.75) + 120 * ($5/12) = $216
How to write an expression for this procedure?To find a mathematical expression for this procedure we must take into account the values that we know.
For example, we know that it requires 15 pansies for each tree. This can be expressed like this:
15 * 8 = 120 pansies.On the other hand, we must calculate the price of each tree and the pansies that are going to be used to surround each one as shown below.
Cost of trees = 8 * $20.75Pansies Cost = 15 * ($5/12)According to the above, the final expression, in which all the necessary data for Katherine is included, is:

A six-sided number cube is rolled and the proportion of 3s is calculated. The graph shows the long-run relative frequency of 100 rolls of this die. A graph titled proportion of threes has frequency on the x-axis, and probability on the y-axis. The graph increases, and then stays steady around y = 0.17. Which conclusion can be drawn from this graph? There is a 20% chance of rolling a 3 with this die. The long-run frequency of rolling a 3 appears to be about 0.17. Because the probabilities on the left part of the graph fluctuate so much, we cannot conclude that this is a fair number cube. This number cube must be fair because each outcome of rolling a 1, 2, 3, 4, 5, or 6 has the same probability of occurring.
The conclusion that can be drawn from this graph on the long-run frequency of 100 rolls is The long-run frequency of rolling a 3 appears to be about 0.17.
What does the graph show?At the 0.17 probability, the proportion of 3s calculated levels off from around the 40th roll to the 100th roll.
This means that the long-run frequency of rolling a 3 is around 0.17 because this was the probability seen for most of the rolls over time.

f(x) has a greater slope. g(x) has a greater slope. The slopes of f(x) and g(x) are the same. The slope of g(x) is undefined."
The correct option from the given function are A; f(x) has a greater slope.
What is the slope of a line which passes through points ( p,q) and (x,y)?Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
The slope of a function in the form of y = mx + C is m,
So the slope in the function
f(x)=4x+10
m = 4
Now when you have a function but you only have a table to evaluate it, to calculate the slope
(p, q) = (4, 7)
(x, y) = (6, 9)
This means that:
[tex]m = \dfrac{y-q}{x-p}\\\\m = \dfrac{9-7}{6-4}\\\\m =1[/tex]
Now that we have both slopes, the slope of g(x) = 1 and the slope of f(x) =4,
Thus, f(x) has a greater slope than g(x).

The square root of a negative number, such as StartRoot negative 144 EndRoot, is undefined. Explain why the square root of –x, StartRoot negative x EndRoot, is not necessarily undefined and what this means about the domain and range of f(x) = StartRoot negative x EndRoot.
Part A
The reason why the (√(-x)) is not necessarily undefined, is because x is a placeholder, such that x can take on a negative value for which (-x) is a positive number, therefore, √(-x) = √(+ve number) is a defined real number.
Part B
The domain is x ≤ 0
The range is f(x) ≥ 0
What is Real Number?A real number is a value of a continuous quantity that can represent a distance along a line.
Here, The given and required information:
Given that √(-144) = Undefined, why is √(-x) not necessarily undefined
The given function, f(x) = √(-x)
Part A
The square root of a real number with a negative value is an imaginary number
The square root of a real number with a positive value or zero, is a real number
√(144) = ±12
A variable, x, is an input value of a function that is a quantity place holder in the function which is a function argument
The given function is f(x) = √(-x)
Where;
x = An argument of the function
When x ≤ 0, such that x is a negative real number or zero, we have;
x = R⁻ or 0
Therefore;
-x= -R⁻ or 0 = R⁺ or 0
-x = R⁺
From which we get;
f(-x)= √(-x) = √(R⁺) = Defined
f(-x) = √(R⁺) ≥ 0 The range of the function is f(x) ≥ 0
An example, when x = -16, we have;
-x = -(-16) = 16
√(-x) √(16) = 4 (Defined)
Part B;
Thee domain where the function is defined is where x = -R⁻, x ≤ 0
The output of the function f(x) is defined which is the range = f(x) ≥ 0
