Is the relation a function? Why or why not?
No. There are x values which map to more than 1 y-value.
Yes. Every y-value maps to exactly 1 x-value.
No. There are y-values which map to more than 1 x-value.
Yes. Every x-value maps to exactly 1 y-value.
No, there are x values which map to more than 1 y-value.
Given that Matthew examines the relation as shown in the below.
{(4, -11), (3,1), (0,1), (2,6), (3, -1)}
We need to check whether the relation is a function or not,
So, we know that,
A relation can map inputs to multiple outputs. It is a function when it maps each input to exactly one output. The set of all functions is a subset of the set of all relations.
If any x values are repeated, and the corresponding y values are different, then we have a relation and not a function.
Here we can see that the y values are repeated, so it is not a function.

This increase would be used to fund a $450 million renovation of the campus football stadium. How many students would need to be selected in the sample if the administrator wants a margin of error of 5% for a 99% con
Answer:
The correct answer is "664".
Step-by-step explanation:
The given values are:
Margin of error,
E = 5%
i.e.,
= 0.05
Level of confidence,
C = 99%
i.e.,

At a Beirut market, oranges are priced at $1.29/KG. Ms. X buys 10 oranges that have a total weight of 4.82 kgs. What is the average price per orange that she pays?
Answer:
The average price of each orange is $0.62.
Step-by-step explanation:
Given that at a Beirut market, oranges are priced at $ 1.29 per kilo, and Ms. X buys 10 oranges that have a total weight of 4.82 kilograms, to determine what is the average price per orange that she pays must perform the following calculation:
(4.82 x 1.29) / 10 = X
6.21 / 10 = X
0.62 = X
Thus, the average price of each orange is $ 0.62.
(1,-2) and (2,-4) exponential formula f(x)=ab^x
We conclude that the exponential function is:
f(x) = -1*(2)ˣ
How to find the exponential function?Here we know that we have an exponential function of the form:
f(x) = a*b^x
And we know two points on the function, that are:
f(1) = -2 = a*b^1 = a*b
f(2) = -4 = a*b^2
Then we have a system of equations to solve, which is:
-2 = a*b
-4 = a*b^2
From the first equation we can solve:
-2/a = b
Replacing that in the other equation we can get:
-4 = a*(-2/a)^2 = 4/a
a = 4/-4 = -1
Now that we know the value of a, we can get the value of b:
-2/a = b
-2/-1 = 2 = b
In this way, we conclude that the exponential function is:
\(f(x) = -1*(2)^x\)

O.5% as a fraction and decimal
Answer: As a fraction: 1/2
As a decimal: 0.005
Step-by-step explanation:
FRACTION:
To figure out how to write 0.5% as a fraction, all you need to know is that 0.5 = to a half, or 1/2 because 0.5 is half of 1.
DECIMAL:
0.5% as a decimal form is 0.005 because it is 1000 times less than 1, so you move the 0 3 times right.
september 11 a recent study asked u.s. adults to name 10 historic events that occurred in their lifetime that have had the greatest impact on the country. the most frequently chosen answer was the september 11, 2001, terrorist attacks, which was included by 76% of the 2025 randomly selected u.s. adults. construct and interpret a 95% confidence interval for the proportion of all u.s. adults who would include the 9/11 attacks on their list of 10 historic events.
We are 95% confident that the true population proportion is between 71.6% and 80.4%
The 95% confidence interval for the proportion of all U.S. grown people who would include those on their list of 10 historic events can be constructed using the formula:
\(CI = pi ± z*(SE)\)Where:
\(pi\) = sample proportion (76%)
SE = standard error (square root of \(pi(1-pi)/n\))
z = the critical value for a 95% confidence level (1.96)
n = sample size (2025)
Plugging in the values, we get:
\(SE =\sqrt{(0.76(1-0.76)/2025)} = 0.0240\\CI = 0.76 ± (1.96)(0.0240) = (0.716, 0.804)\)
The 95% confidence interval can be interpreted as follows: If we repeated this study many times, 95% of the intervals constructed would contain the true population proportion of all U.S. grown persons who would include on their list of 10 historic events. Based on this sample, we are 95% confident that the true population proportion is between 71.6% and 80.4%.

GIVING 100 POINTS: The graph shown here displays the distance, in miles. traveled by a jet in a certain number of hours. Based on the graph, which of the following equations indicates the correct variables, and in how many hours does the jet travel 12,000 miles if it travels at the same speed?
Graph titled Motion of a Jet shows Time in hours on x axis and Distance in miles on y axis. A straight line joins the ordered pairs 0, 0 and 2, 1200 and 4, 2400 and 6, 3600.
y = 600x, the jet travels 12,000 miles in 20 hours
x = 600y, the jet travels 12,000 miles in 20 hours
y = 600x, the jet travels 12,000 miles in 22 hours
x = 600y, the jet travels 12,000 miles in 22 hours
Answer:
A. y = 600x, the jet travels 12,000 miles in 20 hours
Explanation:
\(\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points\)
Take two points: (2, 1200), (4, 2400)
\(\sf slope : \dfrac{2400-1200}{4-2 } = 600\)
Equation:
y - 1200 = 600(x - 2)
y - 1200 = 600x - 1200
y = 600x
Miles the Jet travels at 20 hours:
y = 600(20) = 12000 milesMiles the Jet travels at 22 hours:
y = 600(22) = 13200 milesAnswer:
y = 600x, the jet travels 12,000 miles in 20 hours
Step-by-step explanation:
Slope-intercept form of a linear equation:
\(y = mx + b\)
where:
m = slopeb = y-interceptTo find the slope, define two points on the line and use the slope formula to find the slope:
\(\textsf{let}\:(x_1,y_1)=(0,0)\)\(\textsf{let}\:(x_2,y_2)=(2, 1200)\)\(\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1200-0}{2-0}=600\)
From inspection of the graph, the y-intercept (where the line crosses the y-axis) is at (0, 0). Therefore, the equation of the line is:
y = 600x
y is defined as the distance (in miles). Therefore, to find the number of hours it takes for the jet to travel 12,000 miles, substitute y = 12000 into the found equation and solve for x:
\(\sf \implies 600x=12000\)
\(\sf \implies x=\dfrac{12000}{600}\)
\(\sf \implies x=\dfrac{120}{6}\)
\(\implies \sf x=20\)
Therefore, it takes the jet 20 hours to travel 12,000 miles.

Answer the questions below to find the total surface area of the can.
Answer:
\(\begin{aligned}SA &= 7.125\pi \text{ in}^2\\& \approx 22.4 \text{ in}^2 \end{aligned}\)
Step-by-step explanation:
We can find the Surface Area of the can by adding the areas of each of its parts:
\(SA = 2( A_{\text{base}}) + A_\text{side}\)
First, we can calculate the area of the circular base:
\(A_{\text{circle}} = \pi r^2\)
\(A_{\text{base}} = \pi (0.75 \text{ in})^2\)
\(A_{\text{base}} = 0.5625\pi \text{ in}^2\)
Next, we can calculate the area of the rectangular side:
\(A_\text{rect} = l \cdot w\)
\(A_\text{side} = (4\text{ in}) \cdot C_\text{base}\)
Since the width of the side is the circumference of the base, we need to calculate that first.
\(C_\text{circle} = 2 \pi r\)
\(C_\text{base} = 2 \pi (0.75 \text{ in})\)
\(C_\text{base} = 1.5 \pi \text{ in}\)
Now, we can plug that back into the equation for the area of the side:
\(A_\text{side} = (4\text{ in}) (1.5\pi \text{ in})\)
\(A_\text{side} = 6\pi \text{ in}^2\)
Finally, we can solve for the surface area of the can by adding the area of each of its parts.
\(SA = 2( A_{\text{base}}) + A_\text{side}\)
\(SA = 2(0.5625\pi \text{ in}^2) + 6\pi \text{ in}^2\)
\(\boxed{SA = 7.125\pi \text{ in}^2}\)
\(\boxed{SA \approx 22.4 \text{ in}^2}\)

The probability is 0.8427.
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.
Here we are total number of insurance agents = 89
And number of insurance agents do own a handgun = 75
So we asked probability that a insurance agent will own a handgun
Probability = no.of insurance agents/no.of insurance agents who owns a handgun
Probability = 75/89 = 0.8427
The probability that the agent will own a handgun is .84
