Answer:
Alfredo está en lo correcto porque los números negativos se encuentran a la izquierda del cero y mientras más a la izquierda se encuentra un número negativo, más pequeño será y a medida que te desplazas hacia la derecha mayor será el número. Puedes representar los dos números en una recta numérica de la siguiente forma:
___________________________________________________________
-14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3
Como se ve aquí, -14 se encuentra a la izquierda de -10 y esto significa que es menor. Por esto, Alfredo está en lo correcto al decir que -14 es menor.

13. (a) 120°, 120°, (b) 8.94 cm14. (a) 17.9 cm, (b) 22.4 cmStep-by-step explanation:
Refer to the attached sketch (not to scale)Question 13(a) The center of the circle is also the circumcenter of the triangle PQR.
Since ΔPQR is equilateral, all sides are equal, therefore opposite angles are also congruent:
∠POQ ≅ ∠QOR ≅ PORSum of the three angles is 360° as cover the full circle.
Each angle measure is:
∠POQ = ∠QOR = ∠POR = 360°/3 = 120°(b) Each side is 16 cm and the radius is 12 cm.
The distance of the midpoint M of PQ from the center O is perpendicular bisector of ΔPOQ.
The segment MO is:
MO² = PO² - PM² = PO² - (PQ/2)²MO² = 12² - (16/2)² = 80MO = √80 = 8.94 cm (rounded)Question 14ΔXYZ is isosceles with:
XY = XZ = 20 cmYZ = 18 cm(a) The altitude of ΔXYZ is a perpendicular bisector of YZ. h = XM is the altitude
Find h:
h² = XZ² - ZM² = XZ² - (ZY/2)²h² = 20² - (18/2)² = 319h = √319h = 17.9 cm (rounded)(b) Note the ∠ZXM is half of the ∠ZOM as both the angles intercept half of the arc ZY and ∠ZOM is a central angle.
Find ∠ZXM:
sin ∠ZXM = ZM/ZX = 9 / 20m∠ZXM = arcsin (9/20) = 26.7° (rounded)Find ∠ZOM:
m∠ZOM = 2*m∠ZXM = 2*26.7 = 53.4°Find the measure of the radius:
sin ∠ZOM = ZM/rsin 53.4° = 9/rr = 9 / sin 53.4°r = 11.2 cm (rounded)Find the measure of the diameter:
d = 2r = 2*11.2 cm = 22.4 cm-2( 3x - 1) = -6x - 1

− 2 ( 3 − 1 ) = − 6 − 1
− 6 + 2 = − 6 − 1
Subraction (2 from both sides)
− 6 + 2 = − 6 − 1
− 6 + 2 − 2 = − 6 − 1 − 2
Simplify
− 6 = − 6 − 3
Add 6 to both sides

You pick one card from each set and find the sum. How many different sums are possible? 4 5 6 5 6 7 1 2
There are a total of 9 possible sums. Suppose, the cards in the first set are 4, 5, and 6.
Similarly, the cards in the second set are 5, 6, and 7. A total of nine cards are there. If we choose one card from the first set and one card from the second set, then we get a total of nine possible pairs.
Hence, the sum of these pairs can be 4 + 5, 4 + 6, 4 + 7, 5 + 5, 5 + 6, 5 + 7, 6 + 5, 6 + 6, and 6 + 7. Therefore, there are nine possible sums possible.
Additionally, there are three possibilities in the first set (4, 5, and 6) and three possibilities in the second set (5, 6, and 7).
This means that there are 3 × 3 = 9 possible pairs of cards that we can choose, so there are 9 possible sums.We can list all of these sums as follows:4 + 5 = 96 + 5 = 116 + 5 = 116 + 6 = 127 + 5 = 127 + 6 = 137 + 7 = 14. Therefore, there are a total of 9 possible sums.

Juan has a profitable web business of selling T-shirts priced at $25 each. His demand is pretty steady throughout the year (his website is up and running 365 days a year), approximately normally distributed with a mean of 30 T-shirts/day and a standard deviation of 10 T-shirts/day. He has a supplier in China that charges him $5 per T-shirt T and a flat rate of $150 every time he places an order. Orders take exactly 50 days to arrive by container ship. His calculates his annual per unit holding costs at 20% of the wholesale cost of T-shirts. a) What type of inventory management problem is this? Explain your answer. i) Newsvendor (single period) model ii) EOQ model with continuous demand distribution 111) EOQ model with discrete demand distribution b) Calculate how many T-shirts he should order from his China supplier at a time. c) Calculate the level at which he should reorder T-shirts from China to experience at most a 10% chance of a stocking out. a T-shirts, Juan should place an order for d) Fill in: When inventory drops to more T-shirts.
Juan should order approximately 1,813 T-shirts from his China supplier at a time.
How to explain the informationThis inventory management problem can be categorized as the EOQ (Economic Order Quantity) model with continuous demand distribution. In this case, the demand for T-shirts is approximately normally distributed, and the EOQ model assumes a continuous demand pattern.
In order to calculate the optimal order quantity (EOQ), we can use the following formula:
EOQ = ✓((2 * D * S) / H)
where:
D = Annual demand (mean) = 30 T-shirts/day * 365 days/year = 10,950 T-shirts/year
S = Ordering cost per order = $150
H = Holding cost per unit = 20% of wholesale cost = 0.2 * $5 = $1
EOQ = ✓((2 * 10,950 * 150) / 1)
= ✓(3,285,000)
≈ 1,812.99
Therefore, Juan should order approximately 1,813 T-shirts from his China supplier at a time.

You believe that a corporation's dividends will grow 5% on average into the foreseeable future. If the company's last dividend payment was $5 what should be the current price of the stock assuming a 12% required return?
The calculated value of the current price of the stock is $75
How to calculate the current price of the stockFrom the question, we have the following parameters that can be used in our computation:
Growth = 5%
Required return = 12%
Last dividend payment = $5
The dividend is calculated as
D = Last dividend payment * (1 + Growth )
So, we have
D = 5 * (1 + 5%)
Evaluate
D = 5.25
the current price of the stock is calculated as
Price = D/(r - g)
So, we have
Price = 5.25/(12% - 5%)
Evaluate
Price = 75
Hence, the current price of the stock is $75

Based on the given statistics, we will shape each correlation to the corresponding scatterplot as follows:
13.True or False: r = 0.49 → (2)
14.True or False: r = -0.48 → (4)
15.True or False: r = -0.03 → (3)
16.True or False: r = -0.85 → (1)
Based on the given records, we need to match each correlation fee to the corresponding scatterplot. Let's analyze every correlation and its corresponding scatterplot in more detail:
13.True or False: r = 0.49 → (2)
A correlation coefficient of 0.49 shows a tremendous correlation among the variables. This means that as one variable will increase, the alternative variable tends to grow as nicely, albeit not flawlessly. In the scatterplot categorized as (2), we'd assume to look at a trendy upward fashion wherein the factors are quite scattered around the road of satisfactory fit.
14.True or False: r = -0.48 → (2)
A correlation coefficient of -0.48 indicates a bad correlation between the variables. This manner that as one variable increases, the opposite variable has a tendency to lower. In the scatterplot labeled as (2), we'd expect to see a standard downward fashion wherein the points are rather scattered around the line of fine match.
15.True or False: r = -0.03 → (4)
A correlation coefficient of -0.03 shows a very weak terrible correlation between the variables. This method that there is almost no relationship between the variables. In the scatterplot categorized as (four), we would count on seeing factors scattered randomly, with no discernible pattern or fashion.
16. True or False: r = -0.85 → (1)
A correlation coefficient of -0.85 shows a sturdy poor correlation between the variables. This method that as one variable increases, the other variable has a tendency to decrease substantially. In the scatterplot labeled as (1), we might count on to peer a clear downward trend in which the factors are tightly clustered around the road of the first-rate match.
By analyzing the strengths and instructions of the correlations, we can suit each correlation value to its corresponding scatterplot as follows:
13. True or False: r = 0.49 → (2)
14.True or False: r = -0.48 → (2)
15.True or False: r = -0.03 → (4)
16.True or False: r = -0.85 → (1)

In the experiment of throwing a dice and flipping a coin,
given:
A: getting a number less than 4
B: getting T on a coin
The probabilities of:
A: Getting a number less than 4 on the dice is 1/2
B: Getting tails (T) on the coin is 1/2
In the experiment of throwing a die and flipping a coin, let's define the following events:
A: Getting a number less than 4 on the dice (possible outcomes: 1, 2, 3).
B: Getting tails (T) on the coin.
To determine the probabilities of these events, we need to consider the number of favorable outcomes and the total number of possible outcomes.
For event A:
Number of favorable outcomes: 3 (numbers 1, 2, 3)
Total number of possible outcomes on the dice: 6 (numbers 1 to 6)
So, P(A) = favorable outcomes / total outcomes = 3/6 = 1/2
For event B:
Number of favorable outcomes: 1 (tails T)
Total number of possible outcomes on the coin: 2 (heads H, tails T)
So, P(B) = favorable outcomes / total outcomes = 1/2

Determine if the following systems is a) Linear b) Time-invariant c) Causal, Justify your answer. y(0) = x(t)sinwet
The given system y(0) = x(t)sin(wt) is linear, time-invariant, and causal. It satisfies the properties of superposition and homogeneity, exhibits the same time shift in the output as in the input, and the output at any given time depends only on the current and past values of the input.
a) Linearity: A system is linear if it satisfies the properties of superposition and homogeneity. In this case, the system is linear because it satisfies both properties. The input signal x(t) can be scaled or added together, and the corresponding output y(t) will also be scaled or added accordingly.
b) Time-invariance: A system is time-invariant if a time shift in the input signal results in the same time shift in the output signal. In this case, the system is time-invariant because shifting the input signal x(t) by a time delay will result in the same time delay in the output signal y(t).
c) Causality: A system is causal if the output at any given time depends only on the current and past values of the input. In this case, the system is causal because the output y(t) at any time t depends only on the values of the input x(t) for t' ≤ t.
In conclusion, the given system y(0) = x(t)sin(wt) is linear, time-invariant, and causal based on the justification provided above.

The test statistic of z = 2.58 is obtained when testing the claim that p = 0.85. Find the P-value. (Round the answer to 4 decimal places and enter numerical values in the cell)
Given z-score is z = 2.58 and the null hypothesis isH0: p = 0.85, where p is the true proportion, and we need to find the p-value.
We know that for a two-tailed test, the p-value is the probability that a z-score is greater than or equal to the absolute value of the calculated z-score or less than or equal to its negative value. So, the p-value for a two-tailed test is: p-value = P(z ≥ 2.58) + P(z ≤ -2.58) ..............(1) Here, z = 2.58 represents the upper critical value, and the negative of it is the lower critical value (z = -2.58)
As the given hypothesis is a two-tailed test, we need to calculate the probabilities for both critical values. From the standard normal distribution table, the probabilities for these critical values are:
P(z ≥ 2.58) = 0.0049 (approx.) P(z ≤ -2.58) = 0.0049 (approx.)
Substituting these values in equation (1), we get: p- value = 0.0049 + 0.0049 p-value = 0.0098Hence, the p-value is 0.0098 (approx.)
