The total cost in dollars for Larry to have his birthday party at a local
Trampoline Park can be found using the function t = 6.95p + 29.95, where p is
the number of people who will attend the party. If Larry only has $70 to spend on
his party, which of the following could represent the domain of the function?
Answer:
[tex]0 \leq p < 6[/tex]
Step-by-step explanation:
Given
[tex]t = 6.95p + 29.95[/tex]
[tex]Amount = 70[/tex]
Required
Determine the domain
First, we need to solve for p
Substitute 70 for t in [tex]t = 6.95p + 29.95[/tex]
[tex]70 = 6.95p + 29.95[/tex]
Collect Like Terms
[tex]6.95p = 70 - 29.95[/tex]
[tex]6.95p = 40.05[/tex]
Solve for p
[tex]p = 40.05/6.95[/tex]
[tex]p = 5.76[/tex]
This implies that Larry can not invite up to 6 people.
Hence, the domain can be represented as: [tex]0 \leq p < 6[/tex]
"three times a number is greater than or equal to 12 and less than 21"
Complete the following steps to receive full credit for this question:
• The inequality translated in numerical form
• Your work solving the inequality
• The solution graphed on a number line
• The solution in set notation
• The solution in interval notation
Answer:
The required inequality is: 12 ≤ 3x < 21
Step-by-step explanation:
We are given: three times a number is greater than or equal to 12 and less than 21
We need to answer following questions:
1) The inequality translated in numerical form
Let number = x
12 ≤ 3x < 21
2) Your work solving the inequality
We need to find value of x. Divide the inequality by x
4 ≤ x < 7
3) The solution graphed on a number line
It is shown in figure attached.
4) The solution in set notation
The set notation is: Considering x belongs to natural numbers N
{∀ x|x∈N, 4 ≤ x < 7}
5) The solution in interval notation
The interval notation is: [4,7)
because we have 4 less than equal to x and x is less than 7

Now that you have described several mappings, consider a more general example. Suppose you are given two shapes and you must show that they are congruent using transformations. If the orientation of these two shapes is the same, which type(s) of transformations should you use to show that they are congruent? Why?
We will use Rotational transformation.
What is congruence transformation ?A congruence transformation is getting a congruence or similar image after we do any types of the known transformation.
According to the given question
We are given two shapes and we must show that they are congruent using transformations.
We can show the given two shapes are congruent by Reflections, Rotations and Translations.
Here in the given question it is being said that the orientation of these two shapes is the same so we should use rotational transformations.
In rotational transformation we can rotate a figure in clockwise or in anti-clock wise direction. Rotational transformation can be of any degree but in general we rotate it by 90°, 180°, 270° or by 360°.
In rotational transformation object's side length their adjacent angles remain same.
If by doing some degrees of rotational transformation and the figure looks exactly as before it has then it has rotational symmetry for that value of degrees.

Suppose a least squares regression line is given by y= 4.302x - 3.293. What is the mean value of the response variable if x = 20?
Answer:
i think this is the answer
Step-by-step explanation:
[tex]4.302(20) - 3.293 = 82.747[/tex]
The mean value of the response variable is 82.747.
What is Regression line?Linear Regression calculates the equation of the line that is the best fit for the given data points. Linear regression models a linear relationship between the input variable x and the output variable y.
Here, given regression line;
y= 4.302x - 3.293 ...............(i)
Now, value of x is given; x = 20
Put the value of x in equation (i), we get
y = 4.302 X 20 - 3.293
y = 86.04 - 3.293
y = 82.747
Thus, the mean value of the response variable is 82.747.

(Hat Check problem). n people enter the restaurant and put their hats at the reception. Each person gets a random hat back when going back after having dinner. Find the expected value and variance of the number of people who get their right hat back.
Answer:
E[X] = 1
Var[X] = 1
Step-by-step explanation:
We are told that n people enter the restaurant and put their hats at the reception.
This means that there are n hats.
Also, we are told that eeach person gets a random hat back when going back after having dinner.
Thus, each person will pick a hat uniformly at random and will get a right hat back with the probability: 1/n.
The expectation is linear even though the random variables are dependent. Thus, the expected mean of the total number of persons who get their right hat back is: E[X] = n × 1/n = 1
Now, the variance in hat problem is given by;
Var[X] = E[X²] - E[X]²
This gives;
Var[X] = E[X²] - 1
Now, E[X²] is expressed as;
E[X²] = n(1/n) + n(n - 1)•(1/n)•(1/(n - 1))
E[X²] = 1 + 1
E[X²] = 2
Thus;
Var[X] = 2 - 1
Var[X] = 1

Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

Step-by-step explanation:
to make mixed numbers into improper fractions, you multiply the whole number by the denominator, and add the numerator. you take that answer and make it the numerator in the new improper fraction, and keep the same denominator.
to take the reciprocal switch the numerator and the denominator.

How would you describe the relationship between the real zero(s) and x-intercept(s) of the function
f(x) =
3x(x - 1)
x2(x+3)(x + 1)
When you set the function equal to zero, the solution is x = 1; therefore, the graph has an x-intercept of (1,0).
O When you set the function equal to zero, the solutions are x = 0 or x = 1; therefore, the graph has x-intercepts at
(0, 0) and (1,0).
O When you substitute x = 0 into the function, there is no solution, therefore, the graph will not have any X-
intercepts.
Since there are asymptotes at x = -3, x = -1, and x = 0, the graph has no x-intercepts and therefore, no real
zeros.
The description of the relationship between the real zero(s) and x-intercept(s) of the function should be option A.
Relationship between the real zero(s) and x-intercept(s) of the function:Since it is given that
f(x) = 3x(x - 1)
x2(x+3)(x + 1)
Also, the function should be set out and equivalent to zero when x = 1
and, the graph should have an x-intercept of (1,0).
Therefore, the option A is correct.

Answer:
3/4
Step-by-step explanation:
The value of cos C x sin A is 3/2.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
AB = 1
AC = 2
BC = √3
Now,
∠B = 90°
∠A = 60°
∠C = 180 - (90 + 60) = 180 - 150 = 30°
cos C = cos 30° = √3 / 2
sin A = sin 60° = √3/2
Now,
Cos C x Sin A
= √3/2 x √3 / 2
= 3/2
Thus,
The value is 3/2.
