The area of the circle semicircle will be 13288.28 square centimeters.

Suppose the circle has a radius of 'r' units, then, its area is given as:

A = πr² square unit

The radius of the semicircle is 92 cm.

The area of the semicircle is half of the area of the circle.

Then the area of the circle semicircle will be

A = π x 92² / 2

A = π x 8464/ 2

A = 4232 x 3.14

A = 13288.48 square cm

Step-by-step explanation:

The variance of the length of the critical path is equal to the square of the standard deviation, which in this case is (2.4)² = 5.76.

In the Critical Path Method (CPM), the length of the critical path is determined by the sum of the durations of all activities along the longest path in the project network. Each activity has three time estimates: optimistic (O), pessimistic (P), and most likely (M). These estimates are used to calculate the expected duration of each activity using the PERT (Program Evaluation and Review Technique) formula.

The PERT formula for expected duration (TE) is given by:

TE = (O + 4M + P) / 6

To calculate the variance of the length of the critical path, we need to consider the variances of individual activities and the correlations between them. However, since we are only given the standard deviation (σ) of 2.4, we will make an assumption regarding the shape of the distribution.

Assuming a triangular distribution, the variance (V) can be calculated using the formula:

V = ((P - O) / 6)²

In this case, we know that the standard deviation (σ) is 2.4, and for a triangular distribution, the standard deviation (σ) is related to the range (P - O) as follows:

σ = (P - O) / 6

Rearranging the equation, we can solve for (P - O):

(P - O) = 6σ

Substituting this value back into the variance formula, we get:

V = ((6σ) / 6)² = σ²

In summary, if the standard deviation of the project is 2.4, the variance of the length of the critical path, assuming a triangular distribution, would be 5.76. This indicates the spread or variability in the expected duration of the critical path.

Option (D), the last option is the correct statement, If heights in inches of 200 graduating seniors were summarized in the frequency table;

The median height is greater than or equal to 60 inches but less than 66 inches.

The median is the number value that separates the lower and upper values to halves. The median height is determined by arranging all the given heights in order either from the smallest to highest or from highest to smallest without skipping any measurement of the heights.

After arranging all the heights in order, the median height is usually at the middle.

The reason as to why the median height is greater than or equal to 60 inches but less than 66 inches is because the middle height should not be same as the largest height of 66 inches. It is possible to have multiple 60 inch heights from the 200 seniors. It is also possible to have multiple 66 inch of heights from the 200 seniors.

a). u(n) is the unit step function, b). the ROC includes the entire z-plane except for the pole at z = 0.9 , c). the pole at z = 0.9 lies outside the unit circle, so the system is unstable.

a. To calculate the right-sided (causal) inverse z-transform h(n) of the given transfer function H(z), we can use partial fraction decomposition. First, let's rewrite H(z) as follows:

H(z) = 1.7/(1 + 3.6z^-1) - 0.5/(1 - 0.9z^-1)

By using the method of partial fractions, we can rewrite the above expression as:

H(z) = (1.7/3.6)/(1 - (-1/3.6)z^-1) - (0.5/0.9)/(1 - (0.9)z^-1)

Now, we can identify the inverse z-transforms of the individual terms as:

h(n) = (1.7/3.6)(-1/3.6)^n u(n) - (0.5/0.9)(0.9)^n u(n)

Where u(n) is the unit step function.

b. To plot the poles and zeros of the transfer function, we examine the denominator and numerator of H(z):

Denominator: 1 + 3.6z^-1 Numerator: 1.7

Since the denominator is a first-order polynomial, it has one zero at z = -3.6. The numerator doesn't have any zeros.

The region of convergence (ROC) is determined by the location of the poles. In this case, the ROC includes the entire z-plane except for the pole at z = 0.9.

c. To determine the stability of the system, we need to examine the location of the poles. If all the poles lie within the unit circle in the z-plane, the system is stable. In this case, the pole at z = 0.9 lies outside the unit circle, so the system is unstable.

Step-by-step explanation:

The mass of the original sample of phosphorus-32 was approximately 717.7 grams.

To solve this problem, we can use the radioactive decay formula:

A = Ao * 2^(-t/h)

Where:

A = resulting amount after time t

Ao = initial amount (at t=0)

t = time

h = half-life of the substance

In this case, we are given that the half-life of phosphorus-32 is 14.28 days. We want to find the initial mass, represented by Ao.

After approximately 57 days, 55 g of phosphorus-32 remain unchanged. Let's plug these values into the equation:

55 = Ao * 2^(-57/14.28)

To solve for Ao, we can isolate it by dividing both sides of the equation by 2^(-57/14.28):

55 / 2^(-57/14.28) = Ao

Using a calculator to evaluate 2^(-57/14.28), we find that it is approximately 0.07666.

Therefore, the initial mass, Ao, is:

Ao = 55 / 0.07666 ≈ 717.7 g

Answer:

Parthava had 100 arrows.

Step-by-step explanation:

Let's define N as the number of arrows that Parthava originally has.

He uses one-half of them in defending himself, so he used N/2 arrows

Now he uses four times the square root of the number of arrows, so now he uses:

4*√N

Then he uses 6

Then he uses 3

Then he uses the last one.

If we add all these numbers of arrows that he used, we should get the initial number of arrows that he used, then:

N/2 + 4*√N  + 6 + 3 + 1  = N

Now we have an equation that we can try to solve.

First, let's move all the terms to the same side:

N/2 + 4*√N + 6 + 3 + 1 - N  = 0

now we can simpify it:

(N/2 - N) + 4*√N + (6 + 3 + 1) = 0

-(1/2)*N + 4*√N + 10 = 0

Now we can define a new variable x = √N

Then we have: x^2 = N

now we can replace these new variables in our equation to get:

-(1/2)*x^2 + 4*x + 10 = 0

Now we just have a quadratic equation.

Remember that for a quadratic equation of the form:

0 = a*x^2 + b*x + c

The solutions were given by:

\(x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2a}\)

Then in our case, the solutions will be:

\(x = \frac{-4 \pm \sqrt{4^2 - 4*(-1/2)*10} }{2*(-1/2)} = \frac{-4 \pm 6 }{-1} = 4 \pm 6\)

So there are two solutions:

x = 4 + 6 = 10

x = 4 - 6 = -2

And remember that x = √N

Then x should be positive, then we take x = 10 as our solution here.

then we can use the equation:

x = 10 = √N

then

10^2 = √N^2 = N

10^2 = 100 = N

Parthava had 100 arrows.

Answer:

y = 6

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in y = 3 and x = 9, and solve for k

y = kx

3 = k(9)

1/3 = k

So, the equation is y = 1/3x

Plug in 18 as x and solve for y

y = 1/3x

y = 1/3(18)

y = 6

So, when x = 18, y = 6

The 12% discount off $32 provides a lower final price compared to the 17% discount of $35, making it the better option in terms of cost savings.

To calculate the amount of discount of each item  where Katie and Jill want to purchase their own dressers,

we need to know the original price of the dresser and the percentage discount offered.

Let us assume the original price of each dresser is $X, and the discount percentage is Y%.

The amount of discount of each item can be calculated as,

Discount amount = X × (Y/100)

For example,

If the original price of each dresser is $200 and the discount percentage is 20%, then the amount of discount of each item would be,

Discount amount

= $200 × (20/100)

= $40

So, in this case, there would be a $40 discount of each dresser.

Now, Part Two of the question.

To determine which is the better price between a 17% discount of $35 and a 12% discount of $32,

Calculate the final price after applying each discount.

17% of $35,

Discount amount

= $35 × (17/100)

= $5.95 (rounded to two decimal places)

Final price

= $35 - $5.95

= $29.05

12% of $32,

Discount amount

= $32 × (12/100)

= $3.84 (rounded to two decimal places)

Final price

= $32 - $3.84

= $28.16

Comparing the final prices,

Here $28.16 is a better price than $29.05.

Therefore, the better price is the one with a 12% discount of $32, resulting in a final price of $28.16.

a) Data should order 575 chips if he currently has 25 chips in inventory. b) The most he will ever have to order is 35 chips.

To determine the optimal order quantity for Lieutenant Commander Data, we can use the following approach:

a) If Data currently has 25 chips in inventory, he needs to calculate the reorder point, which is the number of chips he should order to meet the demand during the lead time. The reorder point can be calculated as follows:

Reorder Point = Average Daily Demand * Lead Time

Average Daily Demand = Average Rate per Day * Number of Days

Given:

Average Rate per Day = 4 chips

Lead Time = 5 days

Average Daily Demand = 4 chips * 30 days = 120 chips

Reorder Point = 120 chips * 5 days = 600 chips

Therefore, if Data currently has 25 chips in inventory, he should order 600 - 25 = 575 chips to meet the demand during the lead time.

b) To determine the maximum quantity Data will ever have to order, we need to consider the worst-case scenario where the demand is at its highest during the lead time. The worst-case demand can be calculated as follows:

Worst-Case Demand = (Average Daily Demand + Standard Deviation of Demand) * Lead Time

Given:

Standard Deviation of Demand = 3 chips

Worst-Case Demand = (4 chips + 3 chips) * 5 days = 35 chips

Therefore, the most Data will ever have to order is 35 chips.
