f(x) is a linear function, so both the domain and the range are the set of real numbers.
Consider the given density curve.
A density curve is at y = StartFraction 1 Over 8 EndFraction and goes from negative 10 to negative 2.
What is the value of the median?
–10
–7
–6
–2
Picture posted below…
Answer: -6
Step-by-step explanation:
[tex]\frac{-10-2}{2}=\boxed{-6}[/tex]
The Median of the density is -6.
An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).
It is clearly visible from the uniform density curve given in the question that the median of the population density is -6.
Because the area to the left and right of the density curve is the same.
Hence, the Median of density is -6.

Which formula finds the probability that a point on the grid below will be in the blue area? A grid contains 20 squares. 10 squares are shaded blue. P (blue) = StartFraction total number of squares over number of blue squares EndFraction P (blue) = StartFraction number of blue squares over total number of squares EndFraction P (blue) = StartFraction number of blue squares over number of white squares EndFraction P (blue) = StartFraction number of white squares over number of blue squared EndFraction
The formula that finds the probability that a point on the grid below will be in the blue area is represented by the option:
P (blue) = StartFraction number of blue squares over the total number of squares EndFraction.
The probability = 1/2.
The probability of an event defines the chance of the occurrence of that event. It is given by the ratio of the total number of outcomes favorable to the event to the total number of outcomes in the experiment.
If we suppose an event to be A, the total number of possible outcomes favorable to A be n, and the total number of outcomes in the experiment be S, then the probability of event A can be given as:
P(A) = n/S.
In the question, we are asked to find the formula that defines the probability that a point on the grid will be in the blue area, where the grid contains 20 squares, 10 of them being shaded blue.
We take the event that the chosen point is in the blue area as A.
The total number of outcomes favorable to this event A can be given by n, which will be equal to the number of blue squares = 10
The total number of outcomes in the experiment can be given by S, which will be equal to the number of squares = 20.
Now, the formula for the probability of event A can be written as
P(A) = n/S = 10/20 = 1/2.
The formula that finds the probability that a point on the grid below will be in the blue area is represented by the option:
P (blue) = StartFraction number of blue squares over the total number of squares EndFraction.

A school is arranging a field trip to the zoo. The school spends 737.38 dollars on passes for 44
students and 2 teachers. The school also spends 393.36 dollars on lunch for just the students.
How much money was spent on a pass and lunch for each student?
Step-by-step explanation:
since there is no other information, we have to assume that the prices for student passes and teacher passes are the same.
therefore, the pass price per person is
$737.38 / (44 + 2) = $737.38 / 46 = $16.03
and the lunch costs per student are
$393.36 / 44 = $8.94
altogether,
$16.03 + $8.94 = $24.97
was spent for each student.

What is a quadratic equation?A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.
To find the possible values of x in equation 8x² + 4x = -1, we need to solve for x.
First, we can rearrange the equation to get:
8x² + 4x + 1 = 0
We can solve this quadratic equation using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation in standard form (ax² + bx + c).
In this case, a = 8, b = 4, and c = 1. Substituting these values into the quadratic formula, we get:
x = (-4 ± √(4² - 4(8)(1))) / 2(8)
x = (-4 ± √(16 - 32)) / 16
x = (-4 ± √(-16)) / 16
x = (-4 ± 4i) / 16
where i is the imaginary unit, which is defined as the square root of -1.
Therefore, the possible values of x are:
x = (-4 + 4i) / 16
x = (-4 - 4i) / 16
These values can also be simplified as:
x = -1/2 + i/2
x = -1/2 - i/2
So the possible values of x are complex numbers, specifically x = -1/2 ± i/2.

In your job with the heating contractor you photograph houses with infrared film and use the pictures to determine where to place additional installation you need to buy 18 rolls of film a local camera shop sells to film for $9.95 parole plus 5% sale tax mail order company sells to film for $975 parole and charges $15 to ship the whole order but no charges on sales tax if you choose the better of the two prices how much will you pay for 18 rolls of film
Answer:
$188.06
Step-by-step explanation:
The total cost for the film will be the sum of film cost, applicable sales tax, and applicable shipping charges. The film cost will be the product of the number of rolls and the cost per roll.
__
camera shopfilm cost = (18 rolls) × ($9.95 /roll) = $179.10
sales tax = 0.05 × $179.10 = $8.96
There is no shipping charge associated with the camera shop purchase, so the total cost is ...
camera shop cost = film cost + sales tax = $179.10 +8.96 = $188.06
__
mail orderfilm cost = (18 rolls) × ($9.76 /roll) = $175.50
shipping charge = $15.00
There is no sales tax associated with the mail order, so the total cost is ...
mail order cost = film cost + shipping charge = $175.50 +$15.00 = $190.50
__
The price from the camera shop is the better of the two prices. The purchase there would cost you $188.06 for 18 rolls of film.
_____
Additional comment
The after-tax charge per roll of film at the camera shop is 9.95×1.05 = 10.4475. This is $0.6975 more than the basic charge per roll from the mail order company. In order to get the shipping charge of $15 to be less than $0.6975 per roll, the number of rolls ordered must be more than 15/0.6975 = 21.5.
An order of 22 rolls of film from the mail order company would cost less than from the camera shop. ($229.50 vs. $229.85)

Which table represents a nonlinear function?
What is the equation of the line that passes through the points (5,3) and (9,-13)?
The equation of the line that passes through the given points is y= -4x+23.
Linear FunctionA line can be represented by a linear function. The standard form for the linear equation is: ax+b , for example, y=2x+7. Where:
a= the slope
b=constant term that represents the y-intercept.
From the stardard form equation:
For point (5,3) : 3=5a+b ( equation 1)For point (9,-13) : -13=9a+b (equation 2)Solving the system for equations 1 and 2.
3=5a+b
-13=9a+b * (-1)
3=5a+b
13=-9a-b * (-1)
16= -4a
4= -a
a= -4
If a= -4 from equation 1, you have
3= 5 * (-4)+b
3= -20+b
b=23
Therefore, the line equation is y= -4x+23.

QUESTION 5 1 POINT
Tickets for a basketball game cost $5 for students and $8 for adults. The number of students was 7 less than 11 times the
number of adults. The total amount of money from ticket sales was $3682. How many of each ticket were sold?
Provide your answer below:
FEEDBACK
adult tickets, student tickets
FEED-BACK
Answer:
Adult: 59 tickets, Student: 642 tickets
Step-by-step explanation:
$5 = ticket per student (s)
$8 = ticket per adult (a)
$3682 = total money made
# of s = 11a-7 (7 less than 11 times the adults)
We can use this information to create a systems of equations.
5s + 8a = 3682
*price of a ticket times the number of students or adults equals total*
where s = 11a-7
Now we substitute in:
5(11a-7) + 8a = 3682
55a - 35 + 8a = 3682
63a - 35 = 3682
63a = 3717
a = 59
so 59 adult tickets were sold, now we can use this information to solve for student tickets.
s = 11(59)-7
s = 642
So 59 adult tickets, and 642 student tickets were sold.
