Mr. Foster paid $160 to rent a car for 5 days. If the cost for each day was the same, how much did he pay each day that he rented the car?
Answer is 32
Step-by-step explanation:
Answer:
32
Step-by-step explanation:
160/5 = 32 because if your paying 160 dollars every week you for 1 month which is v weeks you're paying 640 a month for renting a car so if you divide 640/20 you get 32 and 160 /5 is 32
Write the equation of the parabola in vertex form.
vertex (3,1), point (2, - 6)
f(x) =?
Answer:
[tex]f(x)=-7(x-3)^2+1[/tex]
Step-by-step explanation:
Vertex form of a quadratic is given by:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h, k) is the vertex and a is the leading coefficient.
We are given that the vertex is (3, 1). Hence, h = 3 and k = 1. By substitution:
[tex]f(x)=a(x-3)^2+1[/tex]
We are also given a point (2, -6). This means that when x = 2, f(x) = -6. Hence:
[tex]-6=a((2)-3)^2+1[/tex]
Solve for a. Subtract:
[tex]-6=a(-1)^2+1[/tex]
Simplify:
[tex]-6=a+1[/tex]
Therefore:
[tex]a=-7[/tex]
Hence, our quadratic is:
[tex]f(x) = -7 (x-3)^2 + 1[/tex]

HELP PLS
Answer:
D
Step-by-step explanation:
Find the min, Q1, median, Q3, and Max of the data given.
✔️Arrange the data in an ordered manner:
27, 33, 33, 34, 35, 37, 37, 38, 38, 40, 43, 44, 48, 52, 57
✔️Min = 27
✔️Q1 = the 4th data set = 34
✔️Median = the 8th data set = 38
✔️Q3 = 12th data set = 44
✔️Max = 57
Therefore, the box plot that has all these values represented corrected is the box plot in the last option (D).

As part of a class project, a university student surveyed students in the cafeteria to look for a relationship between the students’ eye color and hair color. The table contains the survey results.

(answer)
percentage points. (Round off your answer to the nearest whole number.)
Answer:
18%
Step-by-step explanation:
Divide 64/303.
Divide 9/303.
Subtract the answers and you'll get 18%.
The percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18.25%
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Given here, according to the survey, the population with Brown eyes & black hair and Blue eyes and black hair is 64 and 9 respectively
Also, the marginal total is equal to 303
therefore, the percentages of the two groups are
Brown eyes & black hair =64/303 × 100
= 21.12%
similarly we can calculate Blue eyes and black hair = 9/303 × 100
= 2.97%
Hence the difference is 21.22% - 2.97% = 18.25% (approx)

The asymptote of the function f(x) = 3x + 4 is y =
Answer:
Conclusion:
No vertical asymptotes. No horizontal asymptotes. No slant asymptotes.Step-by-step explanation:
Given the function
f(x) = 3x + 4
Determining the VERTICAL ASYMPTOTES
The line x = L is a vertical asymptote of the function y=3x+4 if the limit of the function (one-sided) at this point is infinite.
It means that possible points are points where the denominator equals 0 or doesn't exist.
So, find the points where the denominator equals 0 and check them.
As can be seen, there are no such points, so this function doesn't have vertical asymptotes.
Determining the HORIZONTAL ASYMPTOTES
Line y = L is a horizontal asymptote of the function y=f(x) if either [tex]\lim _{x\to \infty }\:f\left(x\right)=L[/tex] or [tex]\lim _{x\to -\infty }\:f\left(x\right)=L[/tex], and L is finite.
Calculate the limits:
[tex]\:\lim \:_{x\to \:\infty \:}\:\left(3x+4\right)=\:\infty \:[/tex]
[tex]\:\lim \:_{x\to \:-\infty \:}\:\left(3x+4\right)=\:-\infty \:[/tex]
Thus, there are no horizontal asymptotes
Determining the SLANT ASYMPTOTES
Since the degree of the numerator is not one degree greater than the denominator, then there are no slant asymptotes.

No vertical asymptotes. No horizontal asymptotes. No slant asymptotes.Answer:

Answer:
x=9
Step-by-step explanation:
So first subtract 8 on both Sides
3x+8-8=35-8
3x=27
Now divide 3 on both sides to isolate the variable x
x=9
So x=9
Answer:
so to do this you need to subtract 8 from 35 to get 27 now do 27 divide by 3 to get 9
3x+8=35
3x=35 - 8 = 27
3x = 27

To find the scale factor of a dilation, we first find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the purple shape. The top edge of the black shape measures 15 units while the top edge of the purple shape measures 3 units
Now, we divide the length taken from the figure by the length taken from the original shape. In this case, we divide the length of 3 by the length of 15.

The number of miles a car can travel in 15 gallons = 15 × 35
= 525 miles
Thus, the car will travel 525 miles on 15 gallons of gas.
Ms. Davis is doing an activity with her statistics students where she gives them a 20-question multiple choice test, and they know none of the answers.

Average: 4
Standard Deviation: 0
Step-by-step explanation:
Because we don't know how each student did we are going to assume that they all got 20% of the questions right
20% of 20 is 4

probability that the person will not die in the next year?
what is the
Answer:
0.99186 probability that the person will not die in the next year, and the correct option is A.
Step-by-step explanation:
Dying and not dying in that year are complementary events, that is, one of them will happen. This means that the sum of their probabilities is 100% = 1.
The probability of dying is:
[tex]p = \frac{814}{100000} = 0.00814[/tex]
So the probability of not dying is given by:
[tex]P = 1-0.00814 = 0.99186[/tex]
0.99186 probability that the person will not die in the next year, and the correct option is A.

Describe the solution set of each of the following quadratic inequality or not
Answer:
See below
All the inequalities can be solved by making a table, but once they are simple factored quadratic expressions, we already know what interval it will have.
Step-by-step explanation:
1)
[tex]x^2+9x+14>0[/tex]
Factoring the expression, we have
[tex](x+2)(x+7)>0[/tex]
Considering that
[tex](x+2)(x+7)=0[/tex]
for [tex]x = -2[/tex] and [tex]x=-7[/tex] you can see that for
[tex](x+2)(x+7)>0[/tex]
[tex]x \not\in (-7, -2)[/tex]
Therefore,
[tex]S = \{x\in\mathbb{R} : x<-7 \text{ or } x>-2 \}[/tex]
[tex]S = (-\infty,-7)\cup (-2,\infty)[/tex]
2)
[tex]x^2-10x+16<0[/tex]
You can factor it again.
[tex](x-2)(x-8)<0[/tex]
You can make the table to solve all the inequalities, but once we have the expression [tex]< 0[/tex], we know that
[tex]2<x<8[/tex], therefore,
[tex]S = (2, 8)[/tex]
3)
[tex]2x^2+11x+12<0[/tex]
Factoring we have
[tex](2x+3)(x+4)<0[/tex]
Find the solutions for
[tex](2x+3)(x+4)=0[/tex]
And we know that
[tex]-4<x<-\dfrac{3}{2}[/tex]
[tex]S = \left(-4,-\dfrac{3}{2}\right)[/tex]
Use quadratic regression to find the equation of the parabola going through these 3 points.
(-5,13) (0,8) (2,48)
y=[?]x^2+[?]x+[?]
Answer:
3 + 14 + 8
Step-by-step explanation:
7a=21
a=21
The equation of the parabola that goes through the three points is:
y = 3x² + 14x + 8
The points are given as:
(-5,13), (0,8), (2,48)
To find the equation of the parabola that goes through the given three points (-5,13), (0,8), and (2,48) using quadratic regression, we need to fit a quadratic equation of the form y = ax² + bx + c to these data points.
Using the three points, we can set up a system of equations:
13 = a(-5)² + b(-5) + c
8 = a(0)² + b(0) + c
48 = a(2)² + b(2) + c
Simplifying these equations, we have:
25a - 5b + c = 13
c = 8
4a + 2b + c = 48
Solving this system of equations, we find that a = 3 and b = 14, and c = 8.
Therefore, the equation of the parabola that goes through the three points is:
y = 3x² + 14x + 8
