what's the domain and range function for y=(x-12)^2+11
Answers
Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }
Step-by-step explanation:
Answer:
Step-by-step explanation:
There is no restriction upon x so the domain is all real numbers
x=(-oo, +oo)
y has a minimum value when x=12 and y=11. Any other value of x increases the value of y. So the range is all real numbers greater than or equal to 11.
y=[11, +oo)

Answers
Answer:
[tex]Probability = \frac{11}{40}[/tex]
Step-by-step explanation:
Given
See attachment
Required
The probability that a 7th grader selected will play guitar.
From the attachment, we have:
[tex]7th\ graders =11+8+8+13[/tex]
[tex]7th\ graders =40[/tex]
7th graders that can play guitars are:
[tex]Guitars = 11[/tex]
So, the probability is:
[tex]Probability = \frac{Guitars}{7th\ graders}[/tex]
[tex]Probability = \frac{11}{40}[/tex]
A group of friends met for dinner to get some pizza each friend ate 2/3 of a pizza enter the total amount of pizza the frends ate
Answers
Answer: See explanation
Step-by-step explanation:
You didn't specify the number of friends which is missing in the question. To solve this question, we need to know the number of friends but let's assume that the number of friends are 6.
Since each friend ate 2/3 of a pizza and there are 6 friends, the total amount of pizza the frends ate will be:
== 2/3 × 6
= 4 pizzas

(-2,2) lies above the vertex, so the parabola opens upwards.
Vertex-form equation for an up-opening parabola with vertex (-5,-1):
y = a(x+5)² - 1, a>0
Plug in (-2,2) and solve for a:
2 = a(-2+5)² - 1
a = ⅓

[tex]P(X = 0) = 0.9891[/tex]
Step-by-step explanation:
Given
[tex]\lambda = 0.011[/tex]
Required [This completes the question]
The probability of exactly 0 deaths
This probability follows a Poisson distribution, and it is given by:
[tex]P(X = x) = \frac{e^{-\lambda}\lambda^{x}}{x!}[/tex]
For 0 deaths;
[tex]x = 0[/tex]
So, the expression becomes
[tex]P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{0!}[/tex]
[tex]P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{1}[/tex]
[tex]P(X = 0) = \frac{e^{-\lambda}*1}{1}[/tex]
[tex]P(X = 0) = e^{-\lambda}[/tex]
Substitute 0.011 for [tex]\lambda[/tex]
[tex]P(X = 0) = e^{-0.011}[/tex]
[tex]P(X = 0) = 0.9891[/tex]
The probability of having exactly death is 0.9891

Answer:
0.527
Step-by-step explanation:
From the question,
The sequence is Geometry Progression (G.P)
Tₙ = arⁿ⁻¹.......................... Equation 1
Where n = number of term, a = first term, r = common ratio
Given: n = 7, a = 6, r = 2/3
Substitute these values into equation 1
T₇ = 6(2/3)⁷⁻¹
T₇ = 6(2/3)⁶
T₇ = 6(64/729)
T₇ = 384/729
T₇ = 0.527
Hence, the 7th term of the sequence is 0.527
PLEASE HELP FAST 20 POINTS! Housing prices are often reported using a median. Why is median used in this case? Would arithmetic mean or mode reasonable for comparing housing prices?
Answers
Step-by-step explanation:
The red line in the graph above measures the median home price, and this is often a better "average" for us to be used with home prices and home values. Unfortunately, it is not as easy to calculate and it does not work well with tiny data sets, so we often only see it used with very large data sets (like whole Cities, States, etc.) produced by the large real estate aggregators. Additionally, not many real estate agents know how to generate them for neighborhoods or zip codes (but we can at the Tallahassee Real Estate Blog :)).

WHAT IS EQUIVALENT TO THE INEQUALITY 2X>6?
Answers
Answer:
x > 3
Step-by-step explanation:
Simply isolate the inequality to get a equivalent inequality. Treat the sign > like an equal sign, what you do to one side, you do to the other side of the inequality.
Isolate the variable, x. Divide 2 from both sides of the equation:
(2x)/2 > (6)/2
x > 6/2
x > 3
x > 3 is your equivalent inequality.

Willa and her friend decide to hang out at her friend’s house after basketball practice on Friday to listen to a new album by their favorite band. They have a great time listening to the music and Willa deliberately ignores texts from her dad. When she gets home, her dad is really upset with her. He didn’t know where she was. He has a rule that he needs to know where she is and that she has to ask permission before she goes anywhere. Willa thinks that since she’s in eighth grade, she shouldn’t have to do this anymore. Her dad should trust her more. Willa tells her dad that she’s not a little kid anymore and storms off to her room and slams the door.
