Given the following group of numbers, 8, 2, 9,4, 2, 7, 8, 0, 4, 1, which of the following
is/are true?
I. The mean is 5.
II. The median is 4.
III. The mode is 2.
Answer:
III. The mode is 2
Step-by-step explanation:
Mean: (8+2+9+4+2+7+8+0+4+1)/10 = 45/10 = 4.5
Median: (2+7)/2 = 9/2 = 4.5
Mode: There is no mode since 2 and 8 both appear twice (in other words, since they have the same frequency, it's bimodal)
The closest possible choice is III. The mode is 2, but keep in mind that since the data set is bimodal, there is no single mode.

At the school book fair 3/5 of the books are nonfiction books. Of the nonfiction books 1/4 are animal books. What fraction of the book are animal books?
Answer:
3/20 or 0.15
Step-by-step explanation:
if 3/5=nonfiction and as a part of that 3/5: 1/4=animal
that means that 3/20 (or 0.15) of those books are non fiction animal books
(to get answer you can type "1/4 of 3/5" into calculator!)
Answer:
3/20 or 0.15
explanation: In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator. In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing. Let us understand this concept using an example. The following figure shows a pizza that is divided into 8 equal parts. Now, if we want to express one selected part of the pizza, we can express it as 1/8 which shows that out of 8 equal parts, we are referring to 1 part.
It means one in eight equal parts. It can also be read as: 1 by 8. If 3/5=nonfiction and as a part of that 3/5: 1/4=animal
that means that 3/20 (or 0.15) of those books are non fiction animal books
To get the answer you can also type 1/4 of 3/5 into your calculator.
All fractions consist of a numerator and a denominator and they are separated by a horizontal bar known as the fractional bar. Proper fractions are the fractions in which the numerator is less than its denominator. For example, 5/7, 3/8, 2/5, and so on are proper fractions.

Answer:
Well this is Same side interior angles which would mean that its supplementary or 180.
So we can just,
4x-2+17x+14=180
Combine like terms
21x+12=180
Perform inverse
21x=168
Divide/isolate
x=8
So the value of (x) is 8
Step-by-step explanation:
Well here’s a little tip that might help
So in order to identify interior/exterior angles you have to find the location. The two lines are whats separates the inner and the outter.
The Outter are outside the two parralel lines, their not in between. There are 4 exterior angles.
The inner are the 4 angles between the two parralel lines. There are 4 interior angles.
So there are 5 different ways you would usually hear them.
Alternate interior angle
Alternate exterior angle
Same side exterior (or better known as Converese of the same side exterior)
Same side interior (better known as the converse of the same side interior)
Corresponding
Alternate is basically different sides, but they gotta be only one angle choice, exterior or interior, if correct it makes this slash or back slash if you connect the points.
Same side is basically same side and they have to be the right type (exterior/ interior)
Corresponing has to be the same side also but they have to have.One interior and one exterior.
Corresponing angles are congruent (equal)
Alternate exterior/interior are congruent (equal)
Same side exterior/interior Are supplemenaty (they equal 180)
A 2-column table with 5 rows titled Lou's Shoes. Column 1 is labeled Shoe with entries Sandals, sneakers, running shoes, boots, cleats. Column 2 is labeled Regular price (dollars) with entries x, 10, 12, 14, 16.
Lou’s Shoes is having its annual Flag Day Sale and is offering a 25% discount on all regularly priced shoes. Kayla spends $13.50 buying sandals and sneakers. Determine which equation represents how much Kayla will spend on sandals after the discount.
$13.50 = 0.75(x + 10)
$13.50 – 10 = 0.75x
$13.50 + 10 = 0.75x
$13.50 = 0.25(x + 10)

A number cube is rolled twice. What is the P (2 and then odd number)?
Answer:
P (2 and then odd number) = [tex]\frac{1}{12}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
A number cube is rolled twice.
Possible outcomes are as follows:
[tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]
[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]
[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]
[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]
[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]
[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]
Total number of outcomes = 36
Favorable outcomes include outcomes with 2 and then odd number.
So,
Favorable outcomes are [tex](2,1),(2,3),(2,5)[/tex]
Number of favorable outcomes = 3
Probability is equal to number of favorable outcomes divided by total number of outcomes.
Therefore,
P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes
[tex]=\frac{3}{36}[/tex]
[tex]=\frac{1}{12}[/tex]
On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday to Thursday. What is the temperature on Thursday?
Answer: [tex]-8^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Tuesday is [tex]1^{\circ}C[/tex]
Temperature drops to [tex]-2^{\circ}C[/tex] on Wednesday
Net drop in temperature [tex]1-(-2)=3^{\circ}C[/tex]
The temperature drops twice from Wednesday to Thursday
[tex]\Delta T=2\times 3=6^{\circ}C[/tex]
Temperature on Thursday
[tex]\Rightarrow -2-6=-8^{\circ}C[/tex]
Select the correct answer. Two events, E1 and E2, are defined for a random experiment. Which equation represents the condition that the events are nonexclusive? A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1
Answer:
B
Step-by-step explanation:
The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.
We have given that,
A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1
We have to determine which equation represents the condition that the events are nonexclusive.
What is nonexclusive?
Non-mutually exclusive events are events that can happen at the same time.
The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.

Is the relation shown a function? Explain.
Answer:
no because there are more than 1 X inputs.
Step-by-step explanation:
Answer:
Nope
Step-by-step explanation:
The relation isn't a function because a function is a relation where each x-value has only one corresponding y-value. Try to put a vertical line through that shape made by the graph to test if it's a function. If it passes through multiple points, it's not a function. For example, if you put the vertical line x=3 in that same graph, it will intersect with the relation at points (3, -3) and (3, 4), and therefore is not a function.

Answer:
y = 2x+1
Step-by-step explanation:
From the question,
Using the equation of a straight line
y = mx+c................. Equation 1
Where m = slope of the line, c = intercept on the y axis.
From the graph, The two point co-ordinate shown os
Point 1 = (-2,0)
Point 2 =(6,4)
s = (y₂-y₁)/(x₂-x₁).............. Equation 2
Where y₂ = 6, y₁ = -2, x₂ = 4, x₁ = 0
Substitute into equation 2
s = (6-(-2))/(4-0)
s = (6+2)/4
s = 8/4
s = 2.
Also from the graph,
c = 1
Substitute these values into equation 1
y = 2x+1
Hence the equation of the line is y = 2x+1
