The best measure of location or center is the median.
The best measure of spread or dispersion is the interquartile range (I.Q.R).
Step-by-step explanation:
The data set is skewed to the left since most of the data values fall in the upper end of the distribution. In other words the data set is negatively skewed since it is tailed to the left.
For any skewed data set;
The best measure of location or center is always the median. This is because the median is robust to outliers unlike the mean.
On the other hand, the best measure of spread or dispersion is the interquartile range (I.Q.R).

A company that produces video games has hired you to set the sale price for its newest game. based on the production costs and consumer demands , the company has concluded that the equation p(x) = -0.3x^2 + 45x - 1000 represents the profit p (in dollars) for x individual games sold. What will the company's profit be if 100 games are sold?
Answers
Answer: 500 dollars
You just plug in 100 to the x’s in the equation
The company's profit be if 100 games are sold is $41100
The profit function is given as:
[tex]p(x) = -0.3x^2 + 45x - 1000[/tex]
When the number of games is 100, it means that
x = 100
So, we substitute 100 for x in the profit function
[tex]p(x) = -0.3x^2 + 45x - 1000[/tex] becomes
[tex]p(100) = -0.3(100)^2 + 45(100) - 1000[/tex]
Evaluate the exponents
[tex]p(100) = -0.3(10000) + 45(100) - 1000[/tex]
Open all brackets
[tex]p(100) = -3000 + 45100 - 1000[/tex]
Evaluate like terms
[tex]p(100) = 41100[/tex]
Hence, the company's profit be if 100 games are sold is $41100

What is the solution to this system of equations?
x + 2y − z = 3
2x − y + 2z = 6
x − 3y + 3z = 4
Answers
Answer: The system of equations has no solutions.
Step-by-step explanation:
Identify the equation as:
[tex]x + 2y - z=3[/tex] [Equation 1]
[tex]2x -y + 2z=6[/tex] [Equation 2]
[tex]x - 3y + 3z=4[/tex] [Equation 3]
Multiply [Equation 1] by -2 and add this to [Equation 2] :
[tex](-2)(x + 2y - z)=3(-2)[/tex]
[tex]\left \{ {{-2x - 4y +2z=-6} \atop {2x -y + 2z=6}} \right.\\ ..........................\\-5y+4z=0[/tex]
Find another equation of two variables: Multiply [Equation 3] by -2 and add this to [Equation 2]:
[tex](-2)(x - 3y + 3z)=4(-2)[/tex]
[tex]\left \{ {{2x -y + 2z=6} \atop {-2x +6y -6z=-8}} \right.\\........................\\5y-4z=-2[/tex]
Then you get this new system of equations. When you add them, you get:
[tex]\left \{ {{-5y+4z=0} \atop {5y-4z=-2}} \right.\\..................\\0=-2[/tex]
Since the obtained is not possible, the system of equations has no solutions.
The solution to the system of equations x + 2y - z = 3, 2x - y + 2z = 6, and x - 3y + 3z = 4 is (-1, 1, 2) utilizing substitution method.
Explanation:The subject of this question is to find a solution to the system of linear equations. We can solve this system by methods of either substitution, elimination or matrix - but let's use substitution. First, let's isolate x in the first equation: x = 3 - 2y + z. Then we substitute x into the second and the third equation:
2(3 - 2y + z) − y + 2z = 6(3 - 2y + z) − 3y + 3z = 4
After simplifying these equations, we find y = 1 and z = 2. Plugging these back into x = 3 - 2y + z, we get x = -1. Therefore, the solution to the system is (-1, 1, 2).

Answers
Answer:
2. The correct answer option is 25%.
3. The experimental probability is 3% greater than the theoretical probability.
Step-by-step explanation:
2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.
We are to find the experimental probability of getting the number 2.
P (2) = [tex]\frac{5}{20} \times 100 =\frac{1}{4} \times 100[/tex] = 25%
3. The theoretical Outcomes are: HH HT TH TT
So theoretical probability of getting HH = [tex]\frac{1}{4} \times 100[/tex] = 25%
Total number of outcomes = [tex]28+22+34+16[/tex] = 100

Which of the following piecewise functions is graphed above?
Answers
The answer is:
The piecewise function that represents the graph, is the option A (first option):
f(x) (piecewise function):
[tex]8; x\leq -1\\\\x^{2} -4x+1;-1<x<5\\\\-x+1\geq 5[/tex]
Why?To find the correct option, we need to look for the piecewise function that contains the following functioncs existing in the determined domains (inputs).
From the graph, we know that we need the following functions:
- A horizontal line, which exists from -∞ to -1, givind as input 8.
The function will be:
[tex]y=8[/tex]
Then, the piecewise function it will be:
[tex]8; x\leq -1[/tex]
- A quadratic function (convex parabola) which y-intercept is equal to 1, exists from -1 to 5, and it vertex (lowest point for this case) is located at (2,-3)
The function will be:
[tex]y=x^{2}-4x+1[/tex]
Finding the y-intercept, we have:
[tex]y=0^{2}-4*80)+1[/tex]
[tex]y=1[/tex]
Finding the vertex of the parabola, we have:
[tex]x_{vertex}=\frac{-b}{2}\\\\x_{vertex}=\frac{-(-4)}{2}=\frac{4}{2}=2[/tex]
[tex]y_{vertex}=x_{vertex}^{2}-4x_{vertex}+1[/tex]
[tex]y_{vertex}=2^{2}-4*2+1=4-8+1=-3[/tex]
The vertex of the parabola is located at the point (2,-3).
Then, for the piecewise function it will be:
[tex]x^{2} -4x+1;-1<x<5[/tex]
- A negative slope function, which evaluated at x equal to 5 (input), gives as output -4.
The function will be:
[tex]y=-x+1[/tex]
Proving that it's the correct equation by evaluating "x" equal to 5, we have:
[tex]y=-5+1[/tex]
[tex]y=-4[/tex]
It proves that the equation is correct.
Then, for the piecewise function it will be:
[tex]-x+1\geq 5[/tex]
Hence, we have that the piecewise function that represents the graph, is the option A (first option):
f(x) (piecewise function):
[tex]8; x\leq -1\\\\x^{2} -4x+1;-1<x<5\\\\-x+1\geq 5[/tex]

find the measure of an angle between 0 and 360 coterminal coterminal with the given angle 495 degrees
Answers
Answer:
135 degrees
Step-by-step explanation:
Coterminal means it ends at the same spot around the circle.
To calculate the resulting angle we need to reduce/increase the started value to arrive to a value between 0 and 359 degrees.
If the starting angle is greater or equal to 360, we subtract 360 until we get below 360.
If the starting angle is below 0, we add 360 until we get equal or greater than 0.
So, starting with 495, we subtract 360 a first time....
A = 495 - 360 = 135
We're already in the desired range (0-359)... so we have our answer.

Answer:
Step-by-step explanation:
The sum of the two shorter sides must be greater than the longest side.
5 + 8 = 13
13 is not greater than 14, so the three segments cannot form a triangle.
Answer: No
Step-by-step explanation:
A triangle can be formed only if the sum of 2 sides of the triangle is bigger than the length of the third side of this triangle.
In this case we have AB = 5, BC = 8 and AC = 14.
AB + AC > BC → 5 + 14 > 8 →1 9 > 8 ok!
AB + BC > AC → 5 + 8 > 14 → 13 > 14 false!
BC + AC > AB → 8 + 14 > 5 → 22 > 8 ok!
As we have that AB + BC > AC FALSE, this segments cannot form a triangle.

Determine whether f(x) = -5x2 - 10x + 6 has a maximum or a minimum
value. Find that value and explain how you know.
Answers
Answer:
The function has a maximum
The maximum value of the function is
[tex]f (-1) = 11[/tex]
Step-by-step explanation:
For a quadratic function of the form:
[tex]ax ^ 2 + bx + c[/tex] where a, b and c are the coefficients of the function, then:
If [tex]a <0[/tex] the function has a maximum
If [tex]a> 0[/tex] the function has a minimum value
The minimum or maximum value will always be at the point:
[tex]x=-\frac{b}{2a}\\\y=f(-\frac{b}{2a})[/tex]
In this case the function is: [tex]f(x) = -5x^2 - 10x + 6[/tex]
Note that
[tex]a = -5,\ a <0[/tex]
The function has a maximum
The maximum is at the point:
[tex]x=-\frac{-10}{2(-5)}[/tex]
[tex]x=-1[/tex]
[tex]y=f(-1)[/tex]
[tex]y= -5(-1)^2 - 10(-1) + 6[/tex]
[tex]y= 11[/tex]
The maximum value of the function is
[tex]f (-1) = 11[/tex]
The function [tex]f(x) = -5x^2 - 10x + 6[/tex] has a maximum value at the vertex of its parabola. The maximum value is f(x) = 11 when x = -1.
To determine whether the quadratic function [tex]f(x) = -5x^2 - 10x + 6[/tex] has a maximum or a minimum value, we need to examine the coefficient of the [tex]x^2[/tex]term. The general form of a quadratic function is [tex]f(x) = ax^2 + bx + c.[/tex] If 'a' is negative, the parabola opens downwards, and the function has a maximum value at its vertex. In this case, 'a' is -5, which is negative, so the function has a maximum value.
To find the vertex of the parabola, we use the formula for the x-coordinate of the vertex, which is given by -b/(2a). Here, a = -5 and b = -10. Plugging these values into the formula gives us:
x = -(-10) / (2 * (-5))
x = 10 / -10
x = -1
Now that we have the x-coordinate of the vertex, we can find the y-coordinate (the maximum value) by substituting x = -1 into the original function:
[tex]f(-1) = -5(-1)^2 - 10(-1) + 6[/tex]
f(-1) = -5(1) + 10 + 6
f(-1) = -5 + 10 + 6
f(-1) = 5 + 6
f(-1) = 11
Therefore, the maximum value of the function [tex]f(x) = -5x^2 - 10x + 6[/tex] is 11 when x = -1. This is the value at the vertex of the parabola, confirming that it is the maximum value since the parabola opens downwards.

What is the length of the altitude of the equilateral triangle below
Answers
Answer:
Step-by-step explanation:
Recall that an equilateral triangle has three equal interior angles, all 60°. Let b represent the length of the base. Draw a dashed line from the upper vertex to the base, perpendicularly. This dashed line represents the height or altitude of the triangle.
Now construct a triangle whose opposite side is this altitude, whose hypotenuse is b (and whose base is (1/2)b).
The altitude (opp) is then given by sin Ф = opp / hyp = opp / b. Solving this for the altitude (opp), we get b·sin 60°:
alt (opp) √3
------------- = ------
hyp 2
b·√3
so that 2 alt = b·√3, or alt = ------------

Thus, for any equilateral triangle of side length b, the height of the triangle is
√3
alt = height = b · ------

A survey find that 61% of people are married. They ask the same group of people and 75% of them have at least one kid. If 48% are married and have one kid what is probability that a person in a survey is married or has a child?
Answers
Answer:
22/25
Step-by-step explanation:
The overlap between the 61% and the 75% is the 48%, which means that 13% of the people are married and have no kids (61-48=13)
The 75% includes the people who have one or more kids, and the people who have one or more kids and are married.
Now all we have to do is 13% + 75% = 88% = 22/25
Using Venn probabilities, it is found that there is a 0.88 = 88% probability that a person in a survey is married or has a child.
What is a Venn probability?In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In this question, the events are:
Event A: Person is married.Event B: Person has a child.The probabilities are given by:
[tex]P(A) = 0.61, P(B) = 0.75, P(A \cap B) = 0.48[/tex]
Hence:

X^2-4x+4 is the answer, to save you points next time, use an app called M8thw8y
First you want to drop the parenthesis. If there is a “+” sign, you do not have to change anything. If there is a “-“ sign, you have to distribute the negative in order to simplify, so imagine you are distributing -1 to 7x + 3 to make it -7x -3.
So, you now have x^2 + 3x - 4 + 16 -5 - 7x -3. (I evaluated the 4^2 to 16)
Now, what you want to do now is to combine like terms. Notice that there is only one x^2, so it is the same. There are two terms that have “x”. 3x and -7x react like normal numbers and they form -4x. The numbers who don’t have x on them you combine like terms.
Answer is x^2 - 4x - 12

A bag contains 10 pieces of flavored candy 4 lemon 3 strawberrys 2 grape and 1 cherry one piece of candy will be randomly picked from the bag what is the probability the candy picked is not grape flavored
Answers
Answer:
The probability that the candy picked is not grape flavored would be 4/5
Step-by-step explanation:
We are given that a bag contains 10 pieces of flavored candy. 4 lemon, 3 strawberry, 2 grape and 1 cherry. The probability that the candy picked is not grape flavored is calculated as;
(number of candy that are not grape flavored)/ ( total number of candy in the bag)
= (4+3+1)/(10)
= 8/10
=4/5
Therefore, the probability that the candy picked is not grape flavored would be 4/5
To find the probability that a randomly picked candy is not grape flavored, we will follow these steps:
1. Count the total number of pieces of candy in the bag. This is the sum of all the different flavors of candy:
- 4 lemon candies
- 3 strawberry candies
- 2 grape candies
- 1 cherry candy
The total number is 4 + 3 + 2 + 1 = 10 candies.
2. Count the number of candies that are not grape flavored. Since there are 2 grape candies, the number of candies not grape flavored is the total minus the grape candies:
10 (total candies) - 2 (grape candies) = 8 candies that are not grape flavored.
3. Calculate the probability of picking a non-grape flavored candy. Probability is the number of favorable outcomes divided by the total number of possible outcomes. In our case, the favorable outcomes are the instances where we pick a non-grape flavored candy, and the total possible outcomes are picking any candy from the bag:
Probability (not grape flavored) = Number of non-grape flavored candies / Total number of candies
Probability (not grape flavored) = 8 / 10
4. Simplify the fraction, if needed. In this case, the fraction 8/10 can be simplified to 4/5 by dividing both the numerator and denominator by the greatest common divisor, which is 2.
Therefore, the probability of picking a candy that is not grape flavored from the bag is 4/5, or 80% if expressed as a percentage.
