which of these is the absolute value parent function?
A. f(x) = |x| – 2
B. f(x) = |x|
C. f(x) = |2x|
D. f(x) = |x| + 1
Answers
Answer:
The correct option is B. The absolute value parent function is f(x) = |x|.
Step-by-step explanation:
The absolute parent function is a function where
[tex]f(x)=x[/tex] and [tex]f(-x)=x[/tex]
The graph of absolute function is v-shaped and vertex of the function is (0,0).
According to these conditions the absolute value parent function is
f(x) = |x|
The function f(x) = |x| – 2 shifts 2 units down.
The function f(x) = |2x| stretch by factor 2.
The function f(x) = |x| + 1 shifts 1 units up.
Therefore the correct option is B.

Each morning librarians place 560 books on a book shelf in the school library. Each student that visits library that day takes exactly 3 books from this shelf. Let s be the number of students which visit library on a particular day. Let b be the number of books left on the shelf at the end of that day. a How does the number of books left on the shelf depend on number of students visiting library? Find formula for the function b(s).
Answers
How does the number of books left on the shelf depend on the number of students visiting the library ?
well..if each person takes out 3 books....lets say 10 people came into the library....that would mean (3 * 10) = 30 books would be checked out...but if only 5 people came, then (3 * 5) = 15 books would be checked out. I dont know how else to explain it. The more people that visit, the more books will be checked out.
The relationship between the books and the students is an illustration of a linear function
The formula for the function is: [tex]b(s) = 560 - 3s[/tex]
From the question, we have:
[tex]b = 560[/tex] --- number of books in the morning
[tex]r = 3[/tex] ---- the number of books per students
So, the number of books as a function of number of students is:
[tex]b(s) = b - r \times s[/tex]
Substitute known values
[tex]b(s) = 560 - 3 \times s[/tex]
[tex]b(s) = 560 - 3s[/tex]
Hence, the formula for the function is:
[tex]b(s) = 560 - 3s[/tex]

Let x be a random variable that takes values from 0 to 9 with equal probability 1=10. find the pmf of the random variable y = x mod (3).
Answers
[tex]y=\begin{cases}0&\text{for }x\in\{0,3,6,9\}\\1&\text{for }x\in\{1,4,7\}\\2&\text{for }x\in\{2,5,8\}\end{cases}[/tex]
[tex]\implies\mathbb P(Y=y)=\begin{cases}\dfrac4{10}=\dfrac25&\text{for }y=0\\\\\dfrac3{10}&\text{for }y=1\\\\\dfrac3{10}&\text{for }y=2\end{cases}[/tex]
The pmf of the random variable y = x mod (3) is: P(y=0) = 0.4, P(y=1) = 0.3, and P(y=2) = 0.3.
Explanation:The random variable y can take on the values 0, 1, and 2, since those are the possible remainder values when x is divided by 3. We need to find the probability mass function (pmf) of y, which represents the probabilities of each possible value of y. The pmf of y can be calculated by finding the probability of each possible value of y based on the probability distribution of x and dividing it by the total number of possible values of x. Since x takes values from 0 to 9 with equal probability, the pmf of y is:
P(y=0) = P(x=0) + P(x=3) + P(x=6) + P(x=9) = 1/10 + 1/10 + 1/10 + 1/10 = 4/10 = 0.4
P(y=1) = P(x=1) + P(x=4) + P(x=7) = 1/10 + 1/10 + 1/10 = 3/10 = 0.3
P(y=2) = P(x=2) + P(x=5) + P(x=8) = 1/10 + 1/10 + 1/10 = 3/10 = 0.3

which is another way to write this number? (3 x 1,000) + (3 x 10) (3 x 1/100) + (3 x 1/1000)
Answers
The equivalent expression to (3 x 1,000) + (3 x 10) + (3 x 1/100) + (3 x 1/1000) is 3030.033. This result doesn't require simplification through Exponential or Scientific notation since it's not an especially large or small value.
Explanation:The student's question is asking for an alternative way to write the number produced by the mathematical operation: (3 x 1,000) + (3 x 10) + (3 x 1/100) + (3 x 1/1000). This is a combination of addition and multiplication involving decimal places. It can also be expressed in exponential notation:
First simplify and solve the individual operations: (3 x 1,000) = 3000, (3 x 10) = 30, (3 x 1/100) = 0.03, and (3 x 1/1000) = 0.003.Next, add your results: 3000 + 30 + 0.03 + 0.003 = 3030.033.So, another way to write the stated combination of multiplication and addition operations is 3030.033. The Exponential notation might not be an ideal replacement in this specific case since the result is not a large or small number which normally requires this notation. Scientific notation, (which uses powers of ten to express larger or smaller numbers), could most effectively be implemented if our final result was a very large or very small number.

Red and grey bricks were used to build a decorative wall. There were 140 bricks used in all. How many red bricks were used?
Answers
To find the number of red bricks used to build the decorative wall, we can set up a system of equations. By solving the equations, we find that all 140 bricks used were red bricks.
Explanation:To find the number of red bricks used, we can set up a system of equations.
Let r represent the number of red bricks and g represent the number of grey bricks.
We know that there were 140 bricks used in total, so we can write the equation: r + g = 140.
Since we specifically want to find the number of red bricks, we can write the equation: r = 140 - g.
By substituting this expression for r in the first equation, we get: 140 - g + g = 140.
Simplifying the equation, we find that 140 - g + g = 140 - g + g = 140.
Therefore, 140 - g = 140, and solving for g, we find that g = 0.
This means that no grey bricks were used and all 140 bricks used were red bricks.

Joan can type 50 letters in three hours. When Jill helps, they can do the job in one hour. How long would it have taken Jill to do the job alone?
Answers
Answer:50 in 1.5 hours.
Step-by-step explanation:
If Joan can do 50 in 3 hours, then in 1 hour, that’s 50/3.
Jill completes the rest of the 50, so 50-(50/3) is how many letters Jill can type in an hour.
50-(50/3)=(150/3)-(50/3)=100/3 letters in an hour. If Jill can write 100 letters in 3 hours, then she can write 50 in 1.5 hours.
Anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, and the probability that it is canvas is 0.7. The probability that it is pink and canvas is 0.5. What is the probability that it is pink or canvas.
Answers
the probability is 0.9
Answer: The required probability is 0.9.
Step-by-step explanation: Given that Anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, the probability that it is canvas is 0.7 and the probability that it is pink and canvas is 0.5.
We are to find the probability that the backpack is either pink or canvas.
Let, 'A' and 'B' be the events that the backpack is pink and canvas respectively.
Then, according to the given information, we have
[tex]P(A)=0.7,~~P(B)=0.7,~~P(A\cap B)=0.5,~~~P(A\cup B)=?[/tex]
From the law of probability, we have
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\\Rightarrow P(A\cap B)=0.7+0.7-0.5\\\\\Rightarrow P(A\cap B)=1.4-0.5\\\\\Rightarrow P(A\cap B)=0.9.[/tex]
Therefore, the required probability that the backpack is either pink or canvas is 0.9.
