It is discovered that there is a 0.3934, or 39.34%. likelihood that a customer waits fewer than 30 seconds using the exponential distribution.

The following equation describes an exponential probability distribution with mean m:

f(x) = μe∧(- μe)

The decay parameter is in the following:

μ = 1/m

When x is less than or equal to a, the probability is given by:

P(X ≤ x) = ∫ f(x) dx (limits 0 → a)\

which can be resolved as follows:

P(X ≤ x) = 1 - e∧(- μe)

Since 60 seconds is the mean in this problem, then decay parameter is:

μ = 1/60

The likelihood that a customer will wait under 39 seconds is:

P(X ≤ 30) = 1 - e∧(- 30/60)

P(X ≤ 30) = 0.3934

Thus, the probability that a consumer will wait less than 30 seconds is 0.3934, or 39.34%.

(x - 3)^2 + (y - 10)^2 = 29

This is the equation of a circle centered at (3, 10) with radius sqrt(29). The possible coordinates of the third vertex are the points on this circle.

Let the coordinates of the third vertex be (x, y). Since the triangle is isosceles, the distance between (x, y) and (4, 2) must be equal to the distance between (x, y) and (2, 12).

Using the distance formula, we get:

sqrt((x-4)^2 + (y-2)^2) = sqrt((x-2)^2 + (y-12)^2)

Squaring both sides and simplifying, we get:

x^2 - 6x + y^2 - 20y + 140 = 0

A) we would send Order A to Factory 3.

B) we would send both Order B and Order C to Factory 3.

B 7,000 Factory 3

C 30,000 Factory 3

Total number of units produced for the company today: 37,000

Average cost per unit for all production today: $9.00

To make decisions about which factory to send the orders to on Monday and Tuesday, we need to compare the costs per unit for each factory and consider the total number of units to be produced. Let's go through each day's scenario and make the production decisions.

a) Monday: Order A for 15,000 units

To decide which factory to send the order to, we compare the costs per unit for each factory. We select the factory with the lowest cost per unit to minimize the average cost per unit for the company.

Let's assume the costs per unit for each factory are as follows:

Factory 1: $10 per unit

Factory 2: $12 per unit

Factory 3: $9 per unit

To calculate the total cost for each factory, we multiply the cost per unit by the number of units:

Factory 1: $10 * 15,000 = $150,000

Factory 2: $12 * 15,000 = $180,000

Factory 3: $9 * 15,000 = $135,000

Based on the calculations, Factory 3 has the lowest total cost for producing 15,000 units, with a total cost of $135,000. Therefore, we would send Order A to Factory 3.

b) Tuesday: Order B for 7,000 units and Order C for 30,000 units

We have two options: sending each order to a separate factory or sending both orders to the same factory. We need to compare the average cost per unit for each option and select the one that results in the lowest average cost per unit.

Let's assume the costs per unit for each factory remain the same as in the previous example. We will calculate the average cost per unit for each option:

Option 1: Sending orders to separate factories

For Order B (7,000 units):

Average cost per unit = ($10 * 7,000) / 7,000 = $10

For Order C (30,000 units):

Average cost per unit = ($9 * 30,000) / 30,000 = $9

Total number of units produced for the company today = 7,000 + 30,000 = 37,000

Average cost per unit for all production today = ($10 * 7,000 + $9 * 30,000) / 37,000 = $9.43 (rounded to two decimal places)

Option 2: Sending both orders to the same factory (Factory 3)

For Orders B and C (37,000 units):

Average cost per unit = ($9 * 37,000) / 37,000 = $9

Comparing the two options, we see that both options have the same average cost per unit of $9. However, sending both orders to Factory 3 simplifies the production process by consolidating the orders in one factory. Therefore, we would send both Order B and Order C to Factory 3.

Production Report for Tuesday:

Order # of Units Factory

B   7,000      Factory 3

C  30,000    Factory 3

We can write A = PAP where 1 P= and A= where P is an invertible matrix that maps the null space of A to itself.  

To find the matrix P, we need to solve the following system of linear equations:

λ_1 1 = 1

λ_2 (-4) 1 = 1

λ_3 (-1) 1 = 1

The eigenvalues are real and non-negative, so they can be written as λ = λ_1, λ_2, λ_3 = λ_1, -4, -1 respectively.

Using Cramer's rule, we have:

\(λ_1 * 1^T = 1 * 1^T = 1\)

\(λ_2 * (-4)^T = -4 * 1^T = -4\)

\(λ_3 * (-1)^T = (-1) * 1^T = -1\)

Multiplying the first and third equations, we get:

\(-λ_1 * λ_3 = -4 * (-1) = 4\)

Multiplying the second and third equations, we get:

\(-λ_2 * λ_3 = -4 * (-1) = 4\)

Subtracting the second equation from the first, we get:

\(λ_1^2 - λ_2^2 = 1^2 - (-4)^2 = 5\)

Multiplying the first and third equations, we get:

\(-λ_1 * λ_2 = -4 * (-1) = 4\)

Dividing the third equation by the second equation, we get:

\(-1/λ_2 = -1/λ_3\)

Taking the reciprocal of both sides, we get:λ_2 = λ_3

Substituting this into the second equation, we get:

-\(λ_1 * λ_3 = -4 * (-1) * λ_3 = -4\)

Simplifying, we get:

-4 = -4

Look at my solution

The regression line has a slope of 0.1889 and an intercept of 44.4243. Based on Julie's pre-help total score of 312, her predicted final help score is 100.9939. The linear relationship between pre-help scores and final help scores explains approximately 46.24% of the variation in help scores.

Question 1: To calculate the slope and intercept of the least squares regression line, we can use the given correlation coefficient (r = 0.68) and the standard deviations of the pre-help totals (36) and final help scores (10). The slope is given by r multiplied by the standard deviation of the final help scores divided by the standard deviation of the pre-help totals. Therefore, the slope is (0.68 * 10) / 36 = 0.1889 (rounded to four decimal places). The intercept can be found by subtracting the slope multiplied by the mean of the pre-help totals from the mean of the final help scores. Thus, the intercept is 93 - (0.1889 * 293) = 44.4243 (rounded to four decimal places).

Question 2: To predict Julie's final help score, we can use the regression line equation. Since we know her pre-help total score is 312, we substitute this value into the equation. Therefore, Julie's final help score predicted by the regression line is 0.1889 * 312 + 44.4243 = 100.9939 (rounded to four decimal places).

Question 3: The proportion of variation in help scores explained by the linear relationship between pre-help scores and final help scores can be determined by squaring the correlation coefficient (r) between the two variables. Thus, the proportion explained is 0.68^2 = 0.4624 (rounded to three decimal places), which means approximately 46.24% of the variation in help scores can be explained by the linear relationship with pre-help scores.

The equation 10z - x^2 - y^2 = 0 represents a circular paraboloid with its vertex at the origin (0,0,0). The surface curves downwards in the x and y directions, and the z-coordinate varies linearly with a constant rate.

The surface defined by the equation 10z - x^2 - y^2 = 0 is a circular paraboloid.

Let's analyze the equation to understand the shape of the surface. The equation consists of three terms: 10z, -x^2, and -y^2.

The term 10z represents a linear function of z, indicating that the z-coordinate varies linearly with a constant rate.

The terms -x^2 and -y^2 represent quadratic functions of x and y, respectively. These terms suggest that the surface curves downwards in the x and y directions, forming a circular shape.

The equation can be rewritten as:

x^2 + y^2 - 10z = 0

Comparing this equation to the standard form of a circular paraboloid,

which is given by x^2 + y^2 = 4az, we can observe that the coefficient of z in the equation is -10. This implies that the vertex of the paraboloid is located at the origin (0,0,0), and the surface opens downwards.

Furthermore, the equation lacks a constant term, indicating that the vertex of the paraboloid lies on the xy-plane.

Step-by-step explanation:

To find the value of "t" in the equation v = 8t + 21, we can rearrange the equation to isolate the variable "t."

Subtracting 21 from both sides of the equation gives us v - 21 = 8t. Dividing both sides by 8, we get (v - 21) / 8 = t. Therefore, the value of "t" is (v - 21) divided by 8.

In more detail, the equation v = 8t + 21 represents a linear relationship between speed (v) and time (t). It suggests that the speed (v) is determined by multiplying the time (t) by 8 and adding 21.

By rearranging the equation, we can solve for "t" to find the value of time corresponding to a given speed. In this case, subtracting 21 from both sides isolates the term "8t" on the right side. Dividing both sides by 8 then yields the value of "t" as (v - 21) / 8. This equation allows us to calculate the value of time (t) for any given speed (v) by substituting the speed into the equation.
