Answer:
There is not a way that I can show you how to graph it, so I will try and explain it.
Step-by-step explanation:
(1,1)
^ ^ y-axis
x-axis
You are just going right however many, and then up however many it says.
So if it's (1,1) you will go right one space, and then up one space.
Once you have all of your points on the graph, you put a line through them.

Hello There!
Solving inequalities is almost like solving equations.
x<11.
Let me explain step-by-step.
3x<36-3
3x<33
x<11
We must isolate x.
x < 11 means x is less than 11.
It could be 10, -100, as long as it is less than 11, it would make the inequality true.
Let's verify.
3(10)+3<36
30+3<36
33<36
It's true, isn't it?

Consider a finite population with five elements labeled A, B, C, D, and E. Ten possible simple random samples of size 2 can be selected.
a. Using simple random sampling, what is the probability that each sample of size 2 is selected?
b. Assume the number 1 corresponds to A, the number 2 corresponds to B, and so on. Which of the following represents the simple random sample of size 2 that will be selected by using the random digits 8 0 5 7 5 3 2?
SelectB, CE, CC, BE, ENone of the above
When considering a finite population with five elements labeled A, B, C, D, and E, we are interested in determining the probability of selecting each possible simple random sample of size 2.
In a simple random sample, each combination of elements has an equal chance of being selected. To calculate the probability of selecting each sample, we need to find the total number of possible samples of size 2 from a population of 5. Using the combination formula, we determine that there are 10 possible simple random samples of size 2.
Next, we are given a sequence of random digits: 8 0 5 7 5 3 2. We associate each digit with its corresponding element in the population (1 for A, 2 for B, and so on). By matching the random digits, we find that the selected simple random sample is BC.
Therefore, the probability of selecting each possible sample is 1/10, as each sample has an equal likelihood of being chosen.

There is a 25% chance that Saba will have to wait in line to ride a roller coaster for more than 10 minutes. What is the probability that she does not wait for more than 10 minutes on all 5 roller coasters she rides at the amusement park
Using the binomial distribution, it is found that there is a 0.2373 = 23.73% probability that she does not wait for more than 10 minutes on all 5 roller coasters she rides at the amusement park.
What is the binomial distribution formula?The formula is:
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.The values of the parameters are given as follows:
n = 5, p = 0.25.
The probability that she does not wait for more than 10 minutes on all 5 roller coasters she rides at the amusement park is P(X = 0), hence:
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 0) = C_{5,0}.(0.25)^{0}.(0.75)^{5} = 0.2373\)

What is the end behavior for f(x)=x^5?
The end behavior for f(x)=x^5 is asymptotic growth to positive infinity as x approaches positive infinity and asymptotic growth to negative infinity as x approaches negative infinity.
What is asymptotic growth?Asymptotic growth is a term used to describe the behavior of a function as it approaches a certain value, usually infinity. In mathematics, an asymptotic function is one that grows or shrinks towards a certain point without ever actually reaching it. In other words, it approaches a limit without bound. Asymptotic growth is often used to describe the rate of growth of a function as its input values approach infinity. It is also used to describe the rate at which a function expands or contracts as its argument approaches a certain point. Asymptotic growth is a useful concept in many areas of mathematics, from calculus to number theory.
This is because x^5 becomes increasingly larger as the absolute value of x increases, resulting in an ever-growing value of f(x).

In 2020, a total of 9559 Nissan Leafs were sold in the US. For the 12-month period starting January 2020 and ending December 2020, the detailed sales numbers are as follows: 651, 808, 514, 174, 435, 426, 687, 582, 662, 1551, 1295 and 1774 units.
before the Nissan plant in Smyrna, Tennessee, started to produce the Nissan Leaf they were imported from Japan. Although cars are now assembled in the US, some components still imported from Japan. Assume that the lead time from Japan is one weeks for shipping. Recall that the critical electrode material is imported from Japan. Each battery pack consists of 48 modules and each module contains four cells, for a total of 192 cells. Assume that each "unit" (= the amount required for an individual cell in the battery pack) has a value of $3 and an associated carrying cost of 30%. Moreover, assume that Nissan is responsible for holding the inventory since the units are shipped from Japan. We suppose that placing an order costs $500. Assume that Nissan wants to provide a 99.9% service level for its assembly plant because any missing components will force the assembly lines to come to a halt. Use the 2020 demand observations to estimate the annual demand distribution assuming demand for Nissan Leafs is normally distributed. For simplicity, assume there are 360 days per year, 30 days per month, and 7 days per week.
(a) What is the optimal order quantity?
(b) What is the approximate time between orders?
(a)The optimal order quantity is 4609 units.
(b)The time between orders is 1.98 months.
To determine the optimal order quantity and the approximate time between orders, the Economic Order Quantity (EOQ) model. The EOQ model minimizes the total cost of inventory by balancing ordering costs and carrying costs.
Optimal Order Quantity:
The formula for the EOQ is given by:
EOQ = √[(2DS) / H]
Where:
D = Annual demand
S = Cost per order
H = Holding cost per unit per year
calculate the annual demand (D) using the 2020
sales numbers provided:
D = 651 + 808 + 514 + 174 + 435 + 426 + 687 + 582 + 662 + 1551 + 1295 + 1774
= 9559 units
To calculate the cost per order (S) and the holding cost per unit per year (H).
The cost per order (S) is given as $500.
The holding cost per unit per year (H) calculated as follows:
H = Carrying cost percentage × Unit value
= 0.30 × $3
= $0.90
substitute these values into the EOQ formula:
EOQ = √[(2 × 9559 × $500) / $0.90]
= √[19118000 / $0.90]
≈ √21242222.22
≈ 4608.71
Approximate Time Between Orders:
To calculate the approximate time between orders, we'll divide the total number of working days in a year by the number of orders per year.
Assuming 360 days in a year and a lead time of 1 week (7 days) for shipping, we have:
Working days in a year = 360 - 7 = 353 days
Approximate time between orders = Working days in a year / Number of orders per year
= 353 / (9559 / 4609)
= 0.165 years
Converting this time to months:
Approximate time between orders (months) = 0.165 × 12
= 1.98 months

⭐What is the change in the cyclist's elevation?
The change in the cyclist's elevation is the value of the height (x) - the value of their starting point (0)Thus, we need to solve for the value of the height (x) of the hill.
Notice that the hill is in the shape of a right triangle. In order to find an unknown side length for right triangles, we need to use a trigonometric function.
⭐What is a trigonometric function?
There are 3 trigonometric functions:sin(θ) = opposite/hypotenusecos(θ) = adjacent/hypotenusetan(θ) = opposite/adjacentθ = an angle measureFirst, let's see what kind of side lengths we are given (opposite, hypotenuse, or adjacent).
We are given a side length of 10km, which is the hypotenuse of the triangle, and we are given a side length of x, which is the opposite of θ (13°).
Therefore, we will use the trigonometric function sin(θ) to solve for x.
Substitute the side lengths and angle measures we are given:
\(sin(13) = \frac{x}{10}\)
Set the equation equal to x:
\(10sin(13) = x\)
Solve for x. I recommend using a scientific calculator (e.g. Desmos Scientific Calculator):
\(2.2 = x\)
∴ The cyclist's change in elevation is 2.2 kilometers.

3. Let (X, Jx) and (Y, Ty) be topological spaces defined as follows: X = {D, O, R, K} Tx = {Ø, {0}, {D, O}, {O, R}, {D, O, R}, X} Y = {M, A, T, H} Jy = {0, {M}, {M, A}, {M, A, T}, Y} (a) Let E= {0, K
Given the topological spaces X = {D, O, R, K} with the topology Tx and Y = {M, A, T, H} with the topology Jy, we are asked to determine whether the set E = {0, K} is open in X and open in Y.
To determine whether the set E = {0, K} is open in the topological spaces X and Y, we need to check if E belongs to the respective topologies, Tx and Ty.
In X, the topology Tx is given by: Tx = {Ø, {0}, {D, O}, {O, R}, {D, O, R}, X}. We can see that E = {0, K} is not explicitly listed in Tx. Therefore, E is not open in X since it does not belong to the topology.
In Y, the topology Ty is given by: Jy = {0, {M}, {M, A}, {M, A, T}, Y}. Again, E = {0, K} is not explicitly listed in Ty. Hence, E is not open in Y as it does not belong to the topology.
In both cases, the set E = {0, K} is not open in the respective topological spaces X and Y because it is not a member of the defined topologies.
