A bag of chips costs $2.42. Your total grocery bill, b, is a function of the number of bags of chips, n, you purchase. Write an equation to represent this function,
Answer:
[tex]b(n)=2.42n[/tex]Explanation:
We are told that the grocery bill b is a function of n (the number of bags of chips). This means that the grocery bill can be represented as b(n).
Furthermore, we know that each bag of chips costs 2.42, meaning n bags of chips will cost 2.42n - which is the grocery bill b(n); therefore,
[tex]b(n)=2.42n[/tex]which is the equation the gives the grocery bill (as a function of n, the number of chips bags bought).
The distance between two cities on a map is 4.1 centimeters. The map uses a scale in which 1 centimeter represents 18 kilometers. What is the actual distance between these two cities in kilometers?
The actual distance between the two cities in kilometers is 73.8 kilometers.
Given:
The distance between two cities on a map = 4.1 centimeters
The Scale used by the map is, 1 centimeter is equivalent to 18 kilometers.
To find the actual distance between the two cities in kilometers,
We know, 1 centimeter = 18 kilometers.
For converting the distance in centimeters to kilometers we multiply the value in centimeters by the value of 1 centimeter i.e.18 kilometers.
So, 4.1 centimeter = (4.1 × 18) kilometers
= 73.8 kilometers
Therefore, the actual distance between the two cities calculated in kilometers is 73.8 kilometers.

The question gives us the following function:
[tex]f(x)=\frac{3x}{x-2}[/tex]The X-intercept is where the function crosses the x-axis and the Y-intercept is where the function crosses the y-axis.
X-intercept:
Since the graph must cross the x-axis to have an x-intercept, we should equate f(x) to zero.
[tex]\begin{gathered} f(x)=\frac{3x}{x-2}=0 \\ \\ 3x=0 \\ \therefore x=0\text{ is the x-intercept} \end{gathered}[/tex]Y-intercept:
Since the graph must cross the y-axis to have a y-intercept, we should equate x = 0.
[tex]\begin{gathered} f(x)=\frac{3x}{x-2} \\ \\ f(0)=\frac{3(0)}{0-2} \\ \\ f(0)=0\text{ is a y-intercept} \end{gathered}[/tex]Answer
Thus, the x and y-intercepts are: x = 0 and y = 0 respectively

Which of the following represents the difference quotient for f of x is equal to 4 over x question mark
The difference quotient for the given function is:
[tex]-\frac{4}{x*(x + h)}[/tex]
How to get the difference quotient?For the function f(x), we define the difference quotient as:
[tex]\frac{f(x + h) - f(x)}{h}[/tex]
In this case, the function is f(x) = 4/x, replacing that in the general difference quotient:
[tex]\frac{4/(x + h) - 4/x}{h}[/tex]
Now we can simplify this to get:
[tex]\frac{4/(x + h) - 4/x}{h} = 4*\frac{1/(x + h) - 1/x}{h} \\\\4*\frac{1/(x + h) - 1/x}{h} = 4*(\frac{1/(x + h)}{h} - \frac{1/x}{h})[/tex]
[tex]4*(\frac{1/(x + h)}{h} - \frac{1/x}{h}) = 4*(\frac{1}{(x + h)*h} - \frac{1}{x*h}) = 4*\frac{x - x - h}{x*h*(x + h)} = -\frac{4}{x*(x + h)}[/tex]

Alocal aquarium found that if the price of admission was $10, the attendance was about 1000 customers per week. When the price of admission was dropped to $6,attendance increased to about 2950 per week. Write a linear equation for the attendance in terms of the price,p. (A = mp+b)
Given:
$10 price = 1000 customers per week.
$6 price = 2950 customers per week.
Let's write a linear equation for the attendance in terms of the price, p.
Apply the slope-intercept form:
y = mx + b
In this case, let's use the form:
A = mp + b
Where m is the average rate of change(slope) and b is the y-intercept.
To find the slope, m, apply the slope formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]Where:
(x1, y1) ==> (10, 1000)
(x2, y2) ==> (6, 2950)
Hence, we have:
[tex]m=\frac{2950-1000}{6-10}=\frac{1950}{-4}=-487.5[/tex]The average rate of change is -$487.5
To find the y-intercept, b, substitute either of the points for A and p, substitute -487.5 for x then evaluate.
Let's take the first point: (10, 1000)
A = mp + b
1000 = -487.5(10) + b
1000 = -4875 + b
Add 4875 to both sides:
1000 + 4875 = -4875 + 4875 + b
5875 = b
b = 5875
Therefore, the lineart equation for the attendance in terms of the price, p is:
A = -487.5p + 5875

Your class tried to construct a tetrahedron using four smaller congruent tetrahedra. However, the result left a gap in the center, as shown in the diagram below. If the volume of each small shaded tetrahedron is 50 in.3, what is the volume of the gap? Explain how you know.
Answer:
200 in³
Explanation:
The lengths of the sides of the constructed tetrahedron are twice the length of the side of the small tetrahedron of 50 in³. It means that the scale factor for the solid is 2. So, the complete volume of the constructed tetrahedron is equal to
Vn = 2³(50 in³)
Vn = 8(50 in³)
Vn = 400 in³
However, we only use 4 small tetrahedrons, so the volume of these four solids is
4(50 in³) = 200 in³
Then, the volume of the gap is the difference between the volume of the constructed tetrahedron and the volume of the 4 small tetrahedrons
400 in³ - 200 in³ = 200 in³
So, the answer is 200 in³

(D) what is the probability that at least one out of four randomly sample 18 to 20 years has consumed alcoholic beverage?
(a) The probability that exactly 4 out of 12 randomly sampled 18 to 20 year old consumes an alcoholic drink is 0.008127.
(b) The probability that exactly 8 out of 12, 18 to 20-year-olds have not consumed an alcoholic beverage is 0.231991.
(c) The probability that at most two out of four randomly sampled 18 to 20 year old have consumed alcoholic beverages is 0.35.
(d) The probability that at least one out of four randomly sample 18 to 20 years has consumed alcoholic beverages is 0.99168.
What is probability?The possibility of an event happening is defined by probability. We may need to forecast an event's result in a variety of real-world circumstances. The outcomes of an event may be certain or uncertain to us.
Given that 69.8% of people of 18-20 yr old consume alcohol.
Then p=0.698
Now let X is the random variable denoting the number of people who drinks alcohol.
(a) Let the sample size, n = 12, p = 0.698
It can be seen that X follows a binomial distribution
Then,
P(X=4) = ¹²C₄p⁴(1-p)⁸
= 495 × (0.698)⁴(1-0.698)⁸
=495 × 0.2373 × 0.00006919
= 0.008127
(b) P(X=8) = ¹²C₈p⁸(1-p)⁴
= 12!/ (8!)(4!)(0.698)⁸(1-0.698)⁴
=495 × 0.05634344 × 0.0083181
= 0.231991
(c) Let sample size n=4
p= 0.698
Then,
P(X≤2) = P(X=0)+P(X=1)+P(X=2)
= ⁴C₀p⁰(1-p)⁴ + ⁴C₁p¹(1-p)³ + ⁴C₂p²(1-p)²
=1 × 1× 0.0083181 + 4× 0.698 × 0.0275 + 6× 0.4872 × 0.091204
=0.3516881
=0.35

For P(X≥1)= 1-P(X<1)
=1-P(X=0)
=1-⁴C₀ p⁰(1-p)⁴

The graph is positive only on the intervals where x < –7 and where x > 1. The graph is negative on the interval x < –4.
The statements about the function that are true are
The vertex of the function is at (–3,–16). The graph is increasing on the interval x > –3. The graph is positive only on the intervals where x < –7 and where x > 1. How to interpret the graph?The equation of the graph is given as
f(x) = (x - 1)(x + 7)
The graph of the function is added as an attachment
On the graph, we have
Vertex = (-3, -16)
This is so because the graph has a minimum point of (-3, -16)
Also, the graph crosses the x-axis at x = 1 and x = -7
This means that the graph is positive at x >1 and x >-7
Because the vertex is a minimum, the graph is increasing at the left of its symmetry i.e. x > -3
