0.688 will be the probability of getting a nickel from the jar.

Given,

Probability;-

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The number of fortunate situations divided by the total number of coins would be the product between the probability of each occurrence and the likelihood of each event.

Therefore,

P(nickel) = 19/69

P(penny) = 17/68

That is,

P = 19/69 × 17/68

P = 323/4692

P = 0.0688

That is,

The probability of getting nickel from the jar is 0.06888

Step-by-step explanation:

The function f is increasing on the interval (6, ∞).

The function f will be increasing in the intervals where f'(x) > 0.

To find these intervals, we can examine the sign of each factor of f'(x), which is (x + 1)²(x - 3)⁵(x - 6)⁴.

We can analyze the sign of f(x) by considering the factors individually:

(x+1)²: This factor is always positive since it is the square of a real number.

(x - 3)⁵: This factor is positive when x>3 and negative when x< 3.

(x - 6)⁴: This factor is positive when x>6 and  negative when x< 6.

We need to consider the overlapping regions of positivity for each factor.

When x>6, all three factors are positive, so  f ′ (x) is positive.

When 3<x<6: In this interval, the factor  (x+1)² is positive, but both (x−3)⁵ and (x−6)⁴ are negative.

Thus, f ′ (x) is negative.

When x<−1: In this interval,  (x+1)² is negative, while (x−3)⁵ and (x−6)⁴ are positive.

Hence, f ′ (x) is negative.

Therefore,  the function f(x) is increasing on the interval x>6.

The flow diagram of the given information gives answers of the following questions :

a. Maximum output orders for the process = 1200 orders

b. Time required to pack orders = 20 hours

c. Maximum number of orders to be waiting = 240 orders

Capacity of order taker = 100 Customers/hour

Capacity of Pick orders = 80 Customers/hour

Capacity of pack orders = 60 Customers/hour

Time to take orders = 7 A.M. to 7 P.M.

                                 = 12 hours

Flow diagram of the process,

First step take orders → second Pick orders → Third pack orders ( ready for shipping)

a. Maximum output of the orders from the above flow chart is equal to number of pack orders.

⇒ Maximum output of the orders  = 60 Customers/hour

b. Number of orders taken in one hour = 100

Total number of orders taken in 12 hours = 100 × 12

                                                                    = 1200 orders

maximum number of orders picked and packed = 60

Time required to pack and ready for shipping 1200 orders

= 1200 / 60

= 20 hours

c. Maximum orders picked in 12hours = 80 × 12

                                                                 = 960 orders

Maximum orders waiting

= Number of taken orders - Number of picked orders

= 1200 - 960

= 240 orders

Therefore, from the flow diagram the answers are:

a. Maximum output orders = 1200 orders

b. Time needed to pack orders = 20 hours

c. Maximum waiting orders = 240 orders

The above question is incomplete , the complete question is:

Wally's Widget Warehouse takes orders from 7 A.M. to 7 P.M. The manager wants to analyze the process and has provided the process flow diagram shown below. There are three steps required to ship a customer order. The first step is to take the order from a customer. The second step is to pick the order for the customer and then they have to pack the order ready for shipping. Wally promises that every order placed today gets shipped tomorrow. That means that the picking and packing operation must finish all orders before they go home. Customers - Order Taker (100 Customers/hour) - Customer Orders - Pick Orders (80 Customers/hour) - Picked Orders - Pack Orders (60 Customers/hours) - Wait for Shipper.

Wally wants to figure out the following.

a. What is the current maximum output of the process?

b. How long will the picking and packing operations have to work if we have a day where the order taker works at its maximum capacity.

c. Given b, what is the maximum order waiting to be picked

a)  The bias does not approach zero as A approaches infinity, e^-X is not asymptotically unbiased.

b)  if Y₁ is the best unbiased estimator of P(X=0), we need to compare its MSE with the MSE of any other unbiased estimator.

c) in terms of MSE, Y₁ is better than e^-X with n = 10 and λ = 1.

(a) To check if e^-X is an unbiased estimator of P(X=0), we need to calculate its expected value and check if it is equal to P(X=0).

The moment generating function of Poi(A) is M(t) = exp(A(e^t -1)), and the moment generating function of -X is M(-t) = exp(A(1 - e^t)).

Using the moment generating function of -X, we can calculate the expected value of e^-X as follows:

E(e^-X) = E(exp(-X log(e))) = M(-log(e)) = exp(A(1 - e^-1))

Now, we need to check if E(e^-X) = P(X=0). Since P(X=0) = exp(-A), we can see that the estimator e^-X is biased. The bias is given by B(e^-X) = E(e^-X) - P(X=0) = exp(A(1-e^-1)) - exp(-A).

To check if the bias is asymptotically unbiased, we need to take the limit as A approaches infinity.

lim(A → ∞) B(e^-X) = lim(A → ∞) exp(A(1-e^-1)) - exp(-A) = ∞

Since the bias does not approach zero as A approaches infinity, e^-X is not asymptotically unbiased.

To check if e^-X is the best unbiased estimator of P(X=0), we need to compare its mean squared error (MSE) with the MSE of any other unbiased estimator.

(b) Y₁ is an unbiased estimator of P(X=0) if P(Y₁ = 1) = P(X=0) and P(Y₁ = 0) = 1 - P(X=0). Since Y₁ Ber(P(X=0)), we have

P(Y₁ = 1) = P(X=0) and P(Y₁ = 0) = 1 - P(X=0), which means that Y₁ is an unbiased estimator of P(X=0).

The bias of Y₁ is zero, so it is unbiased and there is no need to check if it is asymptotically unbiased. To check if Y₁ is the best unbiased estimator of P(X=0), we need to compare its MSE with the MSE of any other unbiased estimator.

(c) Using the fact that E(Xi) = λ and Var(Xi) = λ, we can calculate the MSE of e^-X and Y₁ as follows:

MSE(e^-X) = E((e^-X - P(X=0))^2) = Var(e^-X) + B(e^-X)^2 = exp(A(e^-1 - 2)) + (exp(A(1-e^-1)) - exp(-A))^2 - exp(-2A)

MSE(Y₁) = E((Y₁ - P(X=0))^2) = Var(Y₁) = P(X=0)(1-P(X=0)) = exp(-λ)(1-exp(-λ))

Substituting n = 10 and λ = 1, we get:

MSE(e^-X) ≈ 0.1381 + (exp(9)(1-e^-9))^2 - exp(-2) ≈ 1.3869

MSE(Y₁) ≈ exp(-1)(1-exp(-1)) ≈ 0.3935

Therefore, in terms of MSE, Y₁ is better than e^-X with n = 10 and λ = 1.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

The solution of the system of equations 4x+2y = 58 and x+4y = 46 is x = 10 and y = 9

The system of equations

4x+2y = 58

x+4y = 46

To solve this equation we have to use the substitution method

Consider the second equation

x+4y = 46

x = 46-4y

Substitute this value of x in the first equation

4x+2y = 58

4(46-4y) +2y = 58

184 - 16y +2y = 58

-16y +2y = 58-184

Decay

B)

Initial value is 5.

C)

The decay factor is 0.75.

D)

75%

Step-by-step explanation:

An exponential function is given by:

\(f(x)=a(r)^x\)

Where a is the initial value and r is the rate.

We have the function:

\(y=5(1/4)^x\)

So, a = 5 and r = 1/4.

A)

Remember the guidelines:

Our rate is 1/4 or 0.25.

It is less than 1, so our function is exponential decay.

B)

The initial value is the value in front of our rate.

So, our initial value in this case is 5.

C)

The decay factor will be 1 - r, where r is our rate.

Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.

So, we are decaying by a factor of 0.75.

D)

To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.

So, 0.75 will be 75.0 % or smply 75%.

It is a 75% decay.

The length of the rectangular building is 80 meters, since the perimeter is 110 meters and the width is 1/4 of the length.

First, let's determine the width of the rectangular building. Since the length is four times the width, we can set up a proportion. Let x equal the width of the building. Then 4x will equal the length.

4x/x = 110/x

Simplifying this equation gives us:

4 = 110/x

Multiplying both sides by x gives us:

x = 110/4

The width of the building is 27.5 meters.

To find the length, we use the fact that the length is four times the width. So we multiply the width by 4:

Length = \(27.5 * 4 = 110\) meters

Therefore, the length of the rectangular building is 80 meters.

( 2.1, -3.6) is the coordinates of the fourth vertex.

A coordinate system in geometry is a way to use one or more integers, or coordinates, to determine the exact placement of points or other geometrical objects on a manifold, such as Euclidean space.

So, define the missing coordinates as such (a,b).

Let's use the midpoint formula to find the incorrect coordinate now.

The point of reference should be (-2.3, 3.6) A.

Point B should be (2.3, 2.2).

(2.1, 2.2) Make C the focal focus.

At BD, AC's center should be.

Step 1: Find the center of the AC.

Center point of AC:

(-2.3 + 2.1/2), (-3.6 + 2.2/2)

(0.2/2), (1.4/2)

(-0.1, -0.7)

In step two, let's compare the midpoints.

The BD halfway point:

(a + -2.3/2), (b + 2.2/2) =  (-0.1, -0.7)

(a + -2.3/2) = -0.1

(a -2.3/2) = -0.1*2

a = -0.2+2.3

a = 2.1

(b + 2.2/2) = -0.7

b + 2.2 = -0.7*2

b + 2.2 = -1.4

b = -1.4 -2.2

b = -3.6
