Complete Question is attached below:

Alexis made 63 foul shots during the season.

If Alexis made 73% of her foul shots, then she made 0.73 * 86 = 62.78 foul shots during the season.

However, since foul shots must be whole numbers, Alexis would have made either 62 or 63 shots.

We know that Alexis and her team won 15 out of 17 games during the season. This means that Alexis made foul shots in each of these 15 games, for a total of 15 * 2 = 30 foul shots.

If Alexis made a total of 62 foul shots during the season, she would have had to make an additional 32 foul shots in the two games they lost (17 games - 15 games they won = 2 games they lost). That would mean she made 16 foul shots in each of the two games they lost, which is unlikely.

Therefore, Alexis must have made 63 foul shots during the season, leaving only 23 foul shots missed (86 total foul shots - 63 made foul shots).

The chord of the sphere is represented by OT.

The geometrical equivalent of a two-dimensional circle in three dimensions is a sphere. The collection of points in three-dimensional space that are all located at the same r distance from one another is known as a sphere.

The line segment connecting any two locations on a circle's circumference is referred to as the chord of the sphere. It should be emphasized that the diameter is the circle's longest chord, which runs through its center.

So, if L, M, and N lie on the surface of a sphere with its center at point O. Point T lies in the interior of the sphere, then OT would connect two points on the circumference of the sphere.

Hence, the chord of the sphere is represented by OT.

Based on the given scenario, the expected profit if the price is $4 is $11.91, while the price that maximizes the profit is $5.47.

What is the Newsvendor problem?

The Newsvendor problem is a problem in inventory theory that tries to answer the question of how much inventory should be ordered to maximize profit, given limited shelf space or warehouse space, uncertain product demand, and a fixed order quantity. This problem is often encountered in newspaper, magazine, and perishable food industries, and the answer lies in balancing the risk of stocking out (not having enough inventory to meet demand) with the cost of holding excess inventory.

Newsvendor problem with a single product that sells at a price of p and costs $3 per item. Assuming that the store holds 5 products and that the demand is a Poison random variable with rate 10€-(P-3), let’s answer the two questions.

The expected profit (EP) is given by:

EP = Revenue - Cost =

EP = (p*min{Demand, Quantity}) - (3*Quantity)

For the given problem, Quantity is 5, and Demand is a Poison random variable with rate 10€-(P-3). Therefore:

EP(p) = (p*min{Demand, 5}) - (3*5)EP(p)

EP(p) = {p*(1 - exp[-10€-(p-3)] + (5*(1 - exp[-10€-(p-3)]))} - 15.

Using p = $4:

EP(4) = {(4*(1 - exp[-7])) + (5*(1 - exp[-7]))} - 15EP(4)

EP(4) = $11.91

Therefore, the expected profit is $11.91 when the price is $4.

The profit function is given by:

P(p) = (p*(1 - exp[-10€-(p-3)] + (5*(1 - exp[-10€-(p-3)]))} - 15

To maximize the profit, we need to take the derivative of the profit function with respect to p, set it equal to zero, and solve for p:

P'(p) = {1 - exp[-10€-(p-3)]} + p*{10€-(p-3)}*exp[-10€-(p-3)] - 5*{10€-(p-3)}*exp[-10€-(p-3)] = 0

Rearranging and using numerical methods to solve for p, we find:

p = $5.47

Therefore, the price that maximizes the profit is $5.47.

Step-by-step explanation:

The correct option is No; Two sides of triangle PQR and angle PQR are not the same measure as the corresponding sides and angle of triangle STU.

What is Side-Angle-Side (SAS) criterion?

The Side-Angle-Side (SAS) criterion is a rule used in geometry to determine whether two triangles are congruent, which means they have the same size and shape. The SAS criterion states that if two sides and the angle between them in one triangle are equal to two corresponding sides and the angle between them in another triangle, then the two triangles are congruent. This means that all corresponding angles and sides of the two triangles are equal in length and measure.

To determine whether the two triangles are congruent, we can use the side-angle-side (SAS) congruence criterion. We can see that triangle PQR has sides PQ, QR, and RP, and angle QPR, while triangle STU has sides ST, TU, and US, and angle TSU. We can compare the corresponding sides and angles:

PQ is of length 4, and ST is of length 4.

QR is of length 1, and TU is of length 4.

RP is of length 2, and US is of length 2.

Angle QPR is a right angle, while angle TSU is an acute angle.

Therefore, the two triangles do not have the same corresponding sides and angles, and we cannot conclude that they are congruent.

The correct option is:

No; Two sides of triangle PQR and angle PQR are not the same measure as the corresponding sides and angle of triangle STU.

The required diameter of the actual Ricoffy tin container is approximately 92 mm.

By enclosing units in containers—that is, by circling, boxing, or otherwise enclosing units—container numbers indicate magnitude. The worth of each container's contents is multiplied by the number system's fundamental unit. Typically, the basis is either 2 or 10 (the decimal system) (the binary system).

Let the diameter of the actual Ricoffy tin container be d mm.

Since the volume of the tin container is proportional to the cube of its dimensions, and the tin container is 2.5 times smaller than its actual size, we have:

[tex]$(\frac{d}{2.5})^3 = \frac{1}{2.5} \times d^3 = \frac{3}{4} \times 750\text{ g} = 562.5\text{ g}$$[/tex]

where we have used the fact that the actual weight of the coffee is 750g.

Solving for d, we get:

[tex]$$d = \sqrt[3]{\frac{562.5\text{ g}}{\frac{1}{2.5}}} \approx 91.98\text{ mm}$$[/tex]

(a) The probability of a car accident occurring in the two hours is 0.3679.(b) The probability of a car accident occurring between 45 and 75 minutes is 0.3935 (c) The variance of the time until a car accident occurs is 0.0167 d) If a car accident has not happened in 3 hours, the probability it will happen in the next two hours is 0.7385

Since the average rate of car accidents is 1/60 accidents per minute, we can use the Poisson distribution to find the probability:
[tex]P(X = 1) = (e^(-120/60) * (120/60)^1) / 1! = 0.3679[/tex]
So the probability of a car accident occurring in the two hours is 0.3679.

Since the average rate of car accidents is 1/60 accidents per minute, we can use the Poisson distribution to find the probability:
[tex]P(X = 1) = (e^(-30/60) * (30/60)^1) / 1! = 0.3935[/tex], So the probability of a car accident occurring between 45 and 75 minutes is 0.3935.

The variance of a Poisson distribution is equal to the average rate, so the variance of the time until a car accident occurs is: [tex]Var(X) = 1/60 = 0.0167[/tex]Given that no car accident has occurred in the previous 180 minutes. We can use the conditional probability formula to find this probability:

[tex]P(X = 1 | X = 0) = P(X = 1 and X = 0) / P(X = 0) = (e^(-120/60) * (120/60)^1) / (e^(-180/60) * (180/60)^0) = 0.3679 / 0.0498 = 0.7385[/tex]

Answer:  -4 to the 7th power.

Step-by-step explanation:

Answer:

-45,000

Step-by-step explanation:

The probability of X = 2 can be found using the binomial probability formula, with p ≈ 0.119 obtained by solving for p using the equation P(X = 4) = 0.9724. The resulting probability is approximately 0.193.

We can use the binomial probability formula to find P(X = 2):

P(X = 2) = (7 choose 2) * p² * (1-p)⁽⁷⁻²⁾

We know that P(X = 4) = (7 choose 4) * p⁴ * (1-p)⁽⁷⁻⁴⁾ = 0.9724

Solving for p in this equation, we get p ≈ 0.119

Substituting this value of p in the formula for P(X = 2), we get:

P(X = 2) = (7 choose 2) * 0.119² * 0.881⁽⁷⁻²⁾ ≈ 0.193

Therefore, the probability that X = 2 is approximately 0.193.

The total percentage increase in the investor's stock account is 3.7%.

What is the percentage increase?

Percentage increase refers to the amount by which a value or quantity has grown or increased, expressed as a percentage of its original value. It is calculated by dividing the difference between the new value and the original value by the original value, and then multiplying by 100 to express the result as a percentage. The formula for calculating percentage increase is:

Percentage increase = [(New value - Original value) / Original value] x 100%

To find the total percentage increase in the investor's stock account, we need to first calculate the new value of each stock and then add them together.

For Company A:

The stock has increased by 1%, which means its new value is 1% higher than $2000.

The increase in value is 0.01 * $2000 = $20.

The new value of the stock in Company A is $2000 + $20 = $2020.

For Company B:

The stock has increased by 5%, which means its new value is 5% higher than $4240.

The increase in value is 0.05 * $4240 = $212.

The new value of the stock in Company B is $4240 + $212 = $4452.

Now, we can find the total value of the investor's stock account by adding the new values of both stocks:

$2020 + $4452 = $6472

To find the percentage increase, we need to compare the total new value to the original total value:

The original total value was $2000 + $4240 = $6240

The total percentage increase is [(New total value - Original total value) / Original total value] x 100%

Plugging in the numbers: [(6472 - 6240) / 6240] x 100% = 3.7%

Therefore, the total percentage increase in the investor's stock account is 3.7%.
