Answer:

A

Step-by-step Explanation:

Every $1 decrease in price corresponds to a 0.8 increase in the number of pairs of jeans sold.

So, if \(x\) pairs of jeans are sold, the revenue in dollars is \((175-x)(40+0.8x)\).

The roots of this function are \(x=175\) and \(x=-50\). The maximum is achieved halfway between these roots at \(x=62.5\).

When 62.5 pairs of jeans are sold, the price is $112.50.

The store should discount the price to $112.50 to maximize its revenue

Discount is a deduction from the usual cost of something, typically given for prompt or advance payment or to a special category of buyers.

From the above question, every $1 decrease in price corresponds to a 0.8 increase in the number of pairs of jeans sold.

So, if  pairs of jeans are sold, the revenue in dollars is (175 - x)(40 + 0.8x)

The roots of this function are x = 175 and x = -50. The maximum is achieved halfway between these roots at x = 62.50.

Therefore, When 62.5 pairs of jeans are sold, the price is $112.50.

Answer:

C. 48 feet

Step-by-step explanation:

The system of equations is.

\(\begin{cases}\text{x}+\text{y}=60 \\15\text{x}+10\text{y}=800 \end{cases}\)

And the solutions are y = 50 and x = 10.

Let's define the two variables:

With the given information we can write two equations, then the system will be:

\(\begin{cases}\text{x}+\text{y}=60 \\15\text{x}+10\text{y}=800 \end{cases}\)

Now let's solve it.

We can isolate x on the first  to get:

\(\text{x} = 60 - \text{y}\)

Replace that in the other equation to get:

\(15\times(60 - \text{y}) + 10\text{y} = 800\)

\(-2\bold{y} = 900 - 800\)

\(-2\bold{y} = 100\)

\(\text{y} = \dfrac{100}{-2} = \bold{50}\)

Then \(\bold{x=10}\).

Therefore, the solutions are y = 50 and x = 10.

The outcomes that are contained in the events are

1 - P(X) = 4/5 and 1 - P(X) is the same as P(Not X)

From the question, we have the following parameters that can be used in our computation:

X = gray colours

Given that

gray colours = 3 and 10

We have

X = 3 and 10

Not X =1, 2, 4, 5, 6, 7, 8

The probability is then calculated as

P(X) = 2/10 = 1/5

For P(Not X), we have

P(Not X) = 1 - 1/5 = 4/5

In (a), we have

P(Not X) = 1 - 1/5 = 4/5

This means that

P(Not X) = 1 - P(X)

So, the solution is

1 - P(X) = 4/5

After answering the presented question, we can conclude that probability Therefore, the probability of 30 or more seconds between vehicle arrivals is approximately 0.0498.

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% because there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many fields, including statistics, economics, science, and engineering.

The X-axis represents the time between vehicle arrivals, and the Y-axis represents the probability density. The peak of the distribution is at 12 seconds, which is the mean.

b. Probability of the arrival time between vehicles being 12 seconds or less:

Since the mean of the exponential distribution is 12 seconds, we can use the cumulative distribution function (CDF) to find the probability of the arrival time being 12 seconds or less:

\(P(X < = 12) = 1 - e^(-12/12) = 1 - e^(-1) ≈ 0.6321\)

Therefore, the probability of the arrival time between vehicles being 12 seconds or less is approximately 0.6321.

c. Probability of the arrival time between vehicles being 6 seconds or less:

\(P(X < = 6) = 1 - e^(-6/12) = 1 - e^(-0.5) ≈ 0.3935\)

Therefore, the probability of the arrival time between vehicles being 6 seconds or less is approximately 0.3935.

d. Probability of 30 or more seconds between vehicle arrivals:

\(P(X > = 30) = e^(-30/12) ≈ 0.0498\)

Therefore, the probability of 30 or more seconds between vehicle arrivals is approximately 0.0498.

The Value of CD from the second equation into the first equation:2AC = AB + OC + OD⇒ 2AC = AB + AB (By substituting OC = OA and OD = OB)⇒ 2AC = 2AB⇒ AC Therefore, AC is Congruent to c .

Since AC and BD bisect each other at O, we can say that AO = OC and BO = OD.

We need to prove that AC = CD.To do this, we can use the segment addition postulate which states that if a line segment is divided into two parts, the length of the whole segment is equal to the sum of the lengths of the two parts.

Let us draw a diagram to represent the given information:From the diagram, we can see that:AO + OB = AB (By segment addition postulate)OC + OD = CD (By segment addition postulate)AO = OC (Given)BO = OD (Given)

Now, we can substitute the values of AO and OC as well as BO and OD into the equations above:AO + OB = AB ⇒ OC + OB = AB (Substituting AO = OC)OC + OD = CDNow, we can add both equations:OC + OB + OC + OD = AB + CD ⇒ 2(OC + OD) = AB + CDWe know that OC = AO and OD = BO.

Therefore, we can write:2(AO + BO) = AB + CDSince AO = OC and BO = OD, we can write:2(OA + OD) = AB + CDNow, substituting AO = OC and BO = OD, we can write:2AC = AB + CD

Finally, we can substitute the value of CD from the second equation into the first equation:2AC = AB + OC + OD⇒ 2AC = AB + AB (By substituting OC = OA and OD = OB)⇒ 2AC = 2AB⇒ AC

Therefore, AC is congruent to c .

The measure of angle 5 of the exterior hexagon is  m∠5 = 60°.

From the diagram, the shape is a hexagon, so that the total measures of its 6 interior angles are 720 degree.

We assume the interior angles of the hexagon are 1', 2', 3', 4', 5' and 6'.

As all angles 1, 2, 3, 4, 5, 6 are exterior angles of the hexagon, so that we have 6 pairs of supplementary angles: 1 and 1'; 2 and 2'; 3 and 3'; 4 and 4'; 5 and 5'; 6 and 6'.

m∠1 + m∠1' = m∠2 + m∠2' = m∠3+m∠3' = m∠4 + m∠4' = m∠5 + m∠5' = m∠6 + m∠6' = 180⁰

m∠1 + m∠1' + m∠2 + m∠2' + m∠3+m∠3' + m∠4 + m∠4' + m∠5 + m∠5' + m∠6 + m∠6' = 180 × 6 = 1080

(m∠1 + m∠2 + m∠3 + m∠4 + m∠5+m∠6) + (m∠1' + m∠2' + m∠3' + m∠4' + m∠5' + m∠6') = 1080

(m∠1 + m∠2 + m∠3 + m∠4 + m∠5+m∠6) + 720 = 1080

(m∠1 + m∠2 + m∠3 + m∠4 + m∠5 + m∠6)  = 360 (1)

From the question, we know that:

m∠6 = 90

∠1 ≅ ∠2 ≅ ∠3

∠4 ≅ ∠5

Replace ∠1, ∠2 by ∠3; ∠5 by ∠4; ∠6 = 90 in the equation (1), we have;

m∠3 + m∠3 + m∠3 + m∠4 + m∠4 + 90 = 360

3m∠3 + 2m∠4 =270 (2)

As given: m∠4 = m∠3 + 10°

Replace in the equation (2), we have:

3m∠3 + 2 × (m∠3 + 10) =270

3m∠3 + 2m∠3 + 20 = 270

5m∠3 = 270 -20 = 250

m∠3 = 250/5 = 50°

m∠4 = m∠3 + 10° = 50 + 10 = 60°

As ∠4 ≅ ∠5 => m∠5 ≅ m ∠4 = 60°

In this case, the perimeter is 50 feet.

2(Length + Width) = 50

2(Length + 8) = 50

2L + 16 = 50
