How can you use a single measure to describe a data set?
Answers
Answer:
There are many ways to describe a data set using a single measure. Some common ways are to find the mean, median, or mode of the data set.
Step-by-step explanation:
A single measure can be used to describe a data set in the form of a statistic. This statistic can be used to measure the central tendency, dispersion, or shape of the data set. For example, the mean can be used to describe the central tendency of a data set, while the standard deviation can be used to describe the dispersion of a data set.

How to find the probability in a spinner?7) We want to find the probability that the two numbers have an even sum.
The only combinations that produces an even sum are:
(1, 3), (3, 1), (1, 1), (2, 2), (2, 4), (4, 2), (4, 4), (3, 3)
The other combinations of numbers are:
(1, 2), (1, 4), (2, 1), (4, 1), (2, 3), (3, 2), (3, 4), (4, 3)
Thus, we have a total of 16 combinations and the probability that the two numbers have an even sum is:
P(two numbers with even sum) = 8/16 = 0.5

The total surface area of the triangular prism using the net is 96 square units
Calculating the total surface area using the net.From the question, we have the following parameters that can be used in our computation:
The net of a triangular prism
The surface area of the triangular prism from the net is calculated as
Surface area = sum of areas of individual shapes that make up the net of the triangular prism
Using the above as a guide, we have the following:
Area = 2 * 3 * 7 + 6 * 7+ 2 * 1/2 * 2 * 6
Evaluate
Area = 96

There is a linear relationship between the number of people in a group and the cost to enter a museum. The museum charges $20 for two people and $28 for three people.
Part C: Using your work from Part A, complete this prompt: How many people can enter the museum for $100?
Answers
Answer:
11 people could enter for $100
Step-by-step explanation:
According to the information given:
$28=3 people
$20=2 people
so it goes up by 8 dollars for every person added
20-8= 16, the original fee, meaning the sequence formula would be:
8n+8 (n being the number of people)
if 8n+8=100
8n=92
n=11.5 rounded down would be 11
A store sells oranges and apples. Oranges cost $1.00 each and apples cost $2.00 each. In the first sale of the day, 15 fruits were sold in total, and the price was $25. How many of each type of frust was sold? please show the steps to solve THANK YOU!!!!
Answers
Answer:
5 oranges and 10 apples were sold
Step-by-step explanation:
Let x be the number of oranges sold and y be the number of apples sold
Since 15 fruits were sold in all we get the following equation
x + y = 15 ....................[1]
Each orange costs $1 so if x oranges were sold that would fetch x dollars in sales = x dollars in sales
Each apple costs $2 so if y apples were sold, that would result in 2y dollars in sales
Total sales in $ = x + 2y and we know this is $25 so we get the second equation as
x + 2y = 25 ..................[2]
Look at the two equations. The coefficient of the x term is the same. We can eliminate the x term by subtracting equation [1] from equation [2] as follows:
x + 2y = 25
-
x + y = 15
-----------------
y = 10
(2y - y = y and 25-15 = 10)
Now that we know y = 10, we can use equation [1] to find x
x + 10 = 15
which makes x = 5

Which set(s) of numbers does the 20−−√20 belong to? (click all that apply)
Natural Number
Whole Number
Integer
Rational numbers
Irrational Number
please help me
Answers
Given : The number is \(\sqrt{20}\).
To find: Set(s) of numbers in which \(\sqrt{20}\) belong to.
Solution:
We know that,
Natural Number \(=\{1,2,3,...\}\)
Whole Number \(=\{0,1,2,3,...\}\)
Integer \(=\{...-3,-2,-1,0,1,2,3,...\}\)
Rational numbers \(=\{-2,0,3.4,\dfrac{1}{2}\text{ etc}\}\)
Irrational numbers \(=\{\sqrt{2},\sqrt{3},\pi, 1.25436...\text{ etc}\}\)
We have,
\(\sqrt{20}=\sqrt{4\times 5}\)
\(\sqrt{20}=\sqrt{4}\times \sqrt{5}\)
\(\sqrt{20}=2\times \sqrt{5}\)
\(\sqrt{20}=2\sqrt{5}\)
So, \(\sqrt{20}\) is the product of a non zero rational number, i.e., 2 and an irrational number, i.e., \(\sqrt{5}\).
We know that product of a non zero rational number and an irrational number is always irrational.
So, \(\sqrt{20}\) is an irrational number.
Therefore, the correct option is 5.

Graph the following features:
• Y-intercept = 3
Slope = -3
Answers
Answer:
A general linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept (the point at which the line intersects the y-axis).
In this case, we know that the line should intersect the y-axis (the vertical one) at y = 3 (in the point (0, 3))
And the slope is -3, then the equation of the line is:
y = -3*x + 3
To graph this line the general way is to find two points of the line.
So we need to evaluate the function in two different values of x.
In this case, we already know that the line passes through the point (0,3), then we only need to find another point.
To do it, we can just replace the x-value for a value we want, like x = 1
Then the y-value will be:
y = -3*(1) + 3 = -3 + 3 = 0
Then we also have the point (1, 0).
Now that we have two points, we can graph them and draw a line that connects the point, that line is the graph of our linear equation.
An example of this can be seen below.
The 2017 population of California was 39,536,653 and of Arizona was 7,016,270. Compute and compare the rate of pedestrian fatalities per 100,000 residents.
Answers
Answer:
Step-by-step explanation:
In 2017, California led the nation with 858 pedestrian fatalities. Arizona had only 216. The 2017 population of California was 39,536,653 and of Arizona was 7,016,270. Compute and compare the rate of pedestrian fatalities per 100,000 residents.
Solution
The pedestrian fatality rate for California per 100,000 residents
= pedestrian fatality in California / total population in California × 100,000
= (858 / 39,536,653) × 100,000
= 2.17 people per 100,000
The pedestrian fatality rate for Arizona per 100,000 residents
= pedestrian fatality in Arizona / total population in Arizona × 100,000
= (216 / 7,016,270) * 100,000
= 3.08 people per 100,000
This means that, though California may have a higher number of pedestrian fatalities compared to Arizona, the rate of pedestrian fatalities per 100,000 residents in California is lower compared to Arizona.

Next
-4q+6q = 2q
12-6=6
2q+6
Answer:
2q + 6
Step-by-step explanation:
To simplify, we will use the distributive property.
-(2q + 6) simplifies to -2q - 6 (In this case we are distributing the - sign or -1)
3(2q + 4) simplifies to 6q + 12
So if we recombine: -2q - 6 + 6q + 12 - 2q
Let's combine like terms (q's with q's, numbers with numbers)
-2q + -2q + 6q = 2q
-6 + 12 = 6
So if we recombine: 2q + 6

What single decimal multiplier would you use to decrease by 1% followed by a 4% increase?
Answers
Answer:
The single decimal multiplier is 1.0296.
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: \(\frac{100-a}{100}\)
For a increase of a%, we multiply by: \(\frac{100+a}{100}\)
For consecutive changes, we multiply the multipliers.
Decrease of 1%
Multiplication by \(\frac{100-1}{100} = \frac{99}{100} = 0.99\)
Increase of 4%
Multiplication by \(\frac{100+4}{100} = \frac{104}{100} = 1.04\)
Consecutive:
0.99*1.04 = 1.0296
The single decimal multiplier is 1.0296.

The equation of the conic represents a circle with an area of 36π square units.
What kind of conic does a quadratic equation represent?
In this problem we find the equation of the conic in general form, on which we need to determine what kind of conic it represents. This can be done by finding the standard form of the equation by means of algebra properties, using a strategy known as completing the square. The quadratic equation in general form is described by the quadratic equations of the form:
A · x² + B · y² + C · x + D · y + E · x · y + F = 0
Now we proceed to find the standard form of the equation. First, write the equation in standard form:
x² + y² - 3 · x + 6 · y = 7 · x + 2
x² + y² - 10 · x + 6 · y - 2 = 0
Second, complete the square:
(x² - 10 · x + 25) + (y² + 6 · y + 9) = 2 + 25 + 9
(x - 5)² + (y + 3)² = 36
The standard form of the quadratic equation indicates the equation of a circle with a diameter of 12 units and a center at (h, k) = (5, - 3). The area of the circle is calculated below:
A = 0.25π · D²
Where D is the diameter of the circle, in units.
A = 0.25π · 12²
A = 36π
