The probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.

We have following information,

the demand for the polymer is distributed normally .

Mean (μ) = 250 gallons and Standard deviations (σ) = 125 gallons

Selling price of poymer = $25 per gallons

cost price of raw material for polymer= $ 10 per gallons

Salvage value = $(-5)/ gallon

Now, Using the formula for normally distributed sample,

Z = ( X - μ ) /σ

where , X---> sample mean

μ ----> population mean

σ----> standard deviations

Z -----> Z-value

from question it is clear X = 150

putting all the values of variables in above formula we get, Z = ( 150-250)/125 = -100/125

= - 0.8

(-0.8) value of z = 0.21 = 21% , the value of z is measure from normal distribution table.

They will run out of raw material if demands exceds this quantity or

Probability ( out of stock ) = 1 - 0.21 = 0.79 = 79%

So, the probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.

Out of the three parameters, x is an input parameter, while wholep and fracp are considered both input and output parameters.

In the function apart defined in question, there are three parameters: x, wholep, and fracp.

Among these parameters, x is considered an input parameter because it represents the input value that is passed into the function.

The parameters wholep and fracp can be considered both input and output parameters. They are passed by reference (using pointers) and can be modified within the function. The function updates the values of wholep and fracp based on the calculation, which means they can be considered as output values. However, they are also initially provided as input values when the function is called.

Therefore, out of the three parameters, x is an input parameter, while wholep and fracp are considered both input and output parameters.

Step-by-step explanation:

the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.

we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.

Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.

the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

Capital per effective worker in steady state is 6.

In the Cobb-Douglas production function, Y represents output, K represents capital, L represents labor, and α represents the capital share of income.

The formula for capital per effective worker in steady state is:

k* = (s / (n + δ + g))^(1 / (1 - α))

Given:

Capital share (α) = 1/3

Saving rate (s) = 20% = 0.20

Depreciation rate (δ) = 5% = 0.05

Rate of population growth (n) = 2% = 0.02

Rate of labor-augmenting technological change (g) = 1% = 0.01

Plugging in the values into the formula:

k* = (0.20 / (0.02 + 0.05 + 0.01))^(1 / (1 - 1/3))

k* = (0.20 / 0.08)^(1 / (2 / 3))

k* = 2.5^(3 / 2)

k* ≈ 6

Therefore, capital per effective worker in steady state is approximately 6.

In steady state, the economy will have a capital per effective worker of 6

Rounding up gives us a sample size of 7. Thus, we would require a sample size of 7 for 99 percent of the samples' means to be within 10 µmol/L of the population mean. Therefore, option B is correct.

The distribution of albumin levels in cerebrospinal fluid among adults in the US is roughly symmetric with a mean of 29.5 mg/100 ml and a standard deviation of 9.25 mg/100 ml. If repeated samples of size 20 are taken from this population and the mean is calculated for each, how large should the sample be for 99% of their means to lie within 10 µmol/L of the population mean.Solution:The mean of the population is 29.5 mg/100 ml and the standard deviation is 9.25 mg/100 ml, and we're looking for the number of samples required for 99 percent of the samples' means to be within 10 µmol/L of the population mean. The sample size formula is used for this problem.The sample size formula is:$$n

=\left(\d fraction{z*\sigma}{E}\right)^2$$Where, n is the sample size z is the level of significanceσ is the population standard deviation E is the margin of error The formula for margin of error is:E

= z*σ/√nWe require that the sample mean lies within 10 µmol/L of the population mean with a probability of 0.99.Using a standard normal distribution table, we find that the value of z for a 0.995 probability is 2.58.Accordingly, we have:E

= 10 µmol/Lz

= 2.58σ

= 9.25 mg/100 ml The formula for margin of error is:E

= z*σ/√n Solving for n by plugging in the above values we have:$$n

=\left(\dfraction{z*\sigma}{E}\right)^2$$$$n

=\left(\d fraction{2.58*9.25}{10}\right)^2$$$$n

=6.31$$.Rounding up gives us a sample size of 7. Thus, we would require a sample size of 7 for 99 percent of the samples' means to be within 10 µmol/L of the population mean. Therefore, option B is correct.

True . Simpson's rule can only be applied when the function being integrated is normally integrable. This requirement is necessary to ensure that the method is accurate and reliable, and that the approximation of the integral is meaningful.

Simpson's rule is a numerical method for approximating the value of a definite integral. It can only be applied when the function being integrated is integrable, which means that it has a well-defined integral over the given interval. In other words, the function must be continuous and bounded over the interval. If the function is not integrable, Simpson's rule (or any numerical integration method) cannot be used to find the value of the integral.

Simpson's rule is based on approximating the area under a curve by using a series of parabolic arcs. The method is relatively simple and accurate, but it requires that the function being integrated is well-behaved. This means that the function must be continuous and bounded over the interval of integration. If the function is not continuous, or if it is unbounded (i.e., it increases or decreases without limit), then Simpson's rule cannot be used to find the value of the integral. One way to check whether a function is integrable is to use the Riemann criterion, which states that a function is integrable over a given interval if and only if the upper Riemann sum and the lower Riemann sum converge to the same value as the partition size approaches zero.

Answer:

25 is the 14th term.

Step-by-step explanation:

The nth term of a sequence is given by the following explicit rule:

f(n) =5.5n - 52

We need to find the position n of the term of value 25. In other words, find n in the equation:

5.5n - 52=25

Adding 52:

5.5n =25+52=77

Solving:

n=77/5.5

n=14

25 is the 14th term.

a. The alternative hypothesis (H1) specifies that is greater than 26, indicating a directed alternative, this is a one-tailed test.

b. The alternative hypothesis is one-sided and argues that > 26, hence the critical value is 1.645.

c. The value of the test statistic (z-score) is z ≈ 3.82.

d. We reject the null hypothesis (H0) because the test statistic (z = 3.82) is higher than the crucial value (1.645).

In this case, the p-value is the probability of observing a sample mean of 28 or greater, assuming the population mean is 26.

a. This is a one-tailed test because the alternative hypothesis (H1) states that μ is greater than 26, indicating a directional alternative.

b. The decision rule for a one-tailed test at a significance level of 0.05 is to reject the null hypothesis (H0) if the test statistic is greater than the critical value. In this case, the critical value is 1.645 because the alternative hypothesis is one-sided and states that μ > 26.

c. The value of the test statistic (z-score) can be calculated using the formula:

z = (x - μ) / (σ / √n)

where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

In this case:

x = 28

μ = 26

σ = 4

n = 34

Substituting the values into the formula:

z = (28 - 26) / (4 / √34) ≈ 3.82

d. Since the test statistic (z = 3.82) is greater than the critical value (1.645), we reject the null hypothesis (H0).

e-1. To calculate the p-value, we need to find the area under the standard normal distribution curve to the right of the test statistic (z = 3.82). We can use a standard normal distribution table or a calculator to find this area.

The p-value is the probability of observing a test statistic as extreme as the one calculated (or more extreme) under the null hypothesis.

e-2. Interpreting the p-value: The p-value represents the probability of obtaining a sample mean as extreme as the one observed (or more extreme) if the null hypothesis is true.

Therefore, the change-of-coordinates matrix from B to C is: [ 1 ] [ -1 ]

(a) To find the change-of-coordinates matrix from B to C, we need to express the vectors in C (cos 2x, 1) as linear combinations of the vectors in B (sin^2 x, cos^2 x).

Let's express (cos 2x, 1) in terms of B:

(cos 2x, 1) = a(sin^2 x, cos^2 x)

Expanding the right side using scalar multiples a and b:

(cos 2x, 1) = a(sin^2 x, cos^2 x) = (asin^2 x, acos^2 x)

Comparing corresponding components, we have the following equations:

cos 2x = asin^2 x

1 = acos^2 x

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

(cos 2x) / 1 = (asin^2 x) / (acos^2 x)

cos 2x = (sin^2 x) / (cos^2 x)

cos 2x = tan^2 x

Using a trigonometric identity, tan^2 x = sec^2 x - 1, we have:

The distance between the corners represents the hypotenuse of the right angled triangle and another two sides are represented by 5m and 6m .

According to Pythagoras theorem,

\(\rm\implies a^2+b^2 = h^2 \\\)

Here a is 5m and b is 6cm .

\(\rm\implies (5m)^3+(6m)^2 = h^2 \\\)

\(\rm\implies 25m^2+36m^2=h^2\\\)

\(\rm\implies 61m^2=h^2\\\)

\(\rm\implies h =\sqrt{61m^2} \\\)

Hence the distance between the opposite corners is 7.8 m

Yes, it is possible to find a limit at a location where there is a hole in a graph , such as where a point has been removed or where a graph abruptly stops.

This is because the limit of a function is defined as the value that the function approaches as x approaches a given value. In the case of a hole in the graph, the limit is found by looking at the limit from the left, the limit from the right, and the general limit.

The limit from the left is the limit of the function as x approaches the hole from the left. The limit from the right is the limit of the function as x approaches the hole from the right. The general limit is the overall limit of the function at the point where the hole appears. By considering all of these limits, it is possible to determine the overall limit of the function at the point where the hole is present.

The acceleration of the mass at time t=1 is approximately -19.42 inches/second^2.

To find the velocity and acceleration of the mass attached to a vertical spring at time t=1, we need to differentiate the position function with respect to time.

First, we can find the velocity function v(t) by taking the derivative of the position function s(t) with respect to time t:

v(t) = s'(t) = 5cos(2t) * 2 = 10cos(2t)

Plugging in t=1, we get:

v(1) = 10cos(2) ≈ -3.42 inches/second

Therefore, the velocity of the mass at time t=1 is approximately -3.42 inches/second.

Next, we can find the acceleration function a(t) by taking the derivative of the velocity function v(t) with respect to time t:

a(t) = v'(t) = -20sin(2t)

Plugging in t=1, we get:

a(1) = -20sin(2) ≈ -19.42 inches/second^2

Therefore, the acceleration of the mass at time t=1 is approximately -19.42 inches/second^2.

The divergence of the vector field F(x, y, z) = −4 sin(11xy)i – cos(x^6 y)j is 11x cos(11xy) - 6x^5 y sin(x^6 y).

Divergence is a measure of the outflow of a vector field from a point or region of space. In 3D space, it is represented as the scalar dot product of the vector field with the del operator, and is given by the expression div F = ∇·F, where ∇ is the del operator and F is the vector field. The del operator can be represented in terms of the partial derivatives of the vector field with respect to its three independent variables, x, y, and z.

The vector field in this question is F(x, y, z) = −4 sin(11xy)i – cos(x^6 y)j. Therefore, we need to find the divergence of this vector field. Using the formula for divergence, we have:

div F = ∇·F= ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z = (−44xy cos(11xy)) + (−6x^5 y sin(x^6 y)) + 0= -44xy cos(11xy) - 6x^5 y sin(x^6 y)

Hence, the divergence of the vector field F(x, y, z) = −4 sin(11xy)i – cos(x^6 y)j is 11x cos(11xy) - 6x^5 y sin(x^6 y).
