Answer:
R = 2414 units
0.794
Step-by-step explanation:
Given:
Weekly demand, D = 331 units
Lead time (L)= 6 weeks
Standard Deviation (SD) = 85 units
The reorder point is calculated using the relation :
R = D*L + z*(SDw)
SDw = the standard deviation with lead time of 6 weeks ; √6 * 85 = 208.21
z = NORMSINV(0.98) = 2.05
R = (331 * 6) + (2.05 * 208.21)
R = 1986 + 428.122
R = 2414.122
R = 2414 units
The Safety stock, SS
SS = z * SDw
SS = 2.05 * 208.21
SS = 426.8305 units
60% reduction :
426.8305 * (1 - 60%)
= 170.7322
= 171 units
The new service probability ;
SS = z * SDw
171 = z * 208.21
z = 171 / 208.21
z = 0.82
P(Z < 1.02) = 0.7938 = 0.794 = 79.4%

For f(x) = 4x + 2 and g(x) = x^2 - 6, find (f+g)(x)
Answer:
[tex](f+g)(x) = x^2 + 4x - 4[/tex]
Step-by-step explanation:
We are given these following functions:
[tex]f(x) = 4x + 2[/tex]
[tex]g(x) = x^2 - 6[/tex]
(f+g)(x)
We add the common terms. Thus:
[tex](f+g)(x) = f(x) + g(x) = 4x + 2 + x^2 - 6 = x^2 + 4x + 2 - 6 = x^2 + 4x - 4[/tex]
Thus:
[tex](f+g)(x) = x^2 + 4x - 4[/tex]
John estimated the height of his office building to be 13m . The actual height of his office building was 14.7m .
Find the absolute error and the percent error of John's estimate. If necessary, round your answers to the nearest tenth.
Answer:
Percent error = 11.6%
Step-by-step explanation:
Given the following data;
Actual height, A = 14.7 m
Estimated height, E = 13 m
a. To find the absolute error;
Absolute error = A - E
Absolute error = 14.7 - 13
Absolute error = 1.7
b. To find the percent error;
Percent error can be defined as a measure of the extent to which an experimental (estimated) value differs from the actual or theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Substituting into the equation, we have;
[tex] Percent \; error = \frac {13 - 14.7}{14.7} *100[/tex]
[tex] Percent \; error = \frac {1.7}{14.7} *100[/tex]
[tex] Percent \; error = 0.1157 *100[/tex]
Percent error = 11.57 ≈ 11.6%

Jacob knows that the adult population gets, on average, eight hours of sleep each night. A hypothesis test can help him see if college students are different from the adult population. From a sample of 101 students, Jacob tabulated that his sample of students got an average of 7.3 hours of sleep each night, with a standard deviation of 2.6.
Required:
What is the t- statistic that Jacob calculates?
Answer:
The t-statistic that Jacob calculates is [tex]t = -2.71[/tex]
Step-by-step explanation:
Jacob knows that the adult population gets, on average, eight hours of sleep each night. A hypothesis test can help him see if college students are different from the adult population.
At the null hypothesis, we test if the mean is of 8 hours, that is:
[tex]H_0: \mu = 8[/tex]
At the alternative hypothesis, we test if the mean is different of 8 hours, that is:
[tex]H_1: \mu \neq 8[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
8 is tested at the null hypothesis:
This means that [tex]\mu = 8[/tex]
From a sample of 101 students, Jacob tabulated that his sample of students got an average of 7.3 hours of sleep each night, with a standard deviation of 2.6.
This means that [tex]n = 101, X = 7.3, s = 2.6[/tex]
What is the t-statistic that Jacob calculates?
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{7.3 - 8}{\frac{2.6}{\sqrt{101}}}[/tex]
[tex]t = -2.71[/tex]
The t-statistic that Jacob calculates is [tex]t = -2.71[/tex]

Answer:
No , it is not a right angle triangle
Step-by-step explanation:
according to the pythagoras theorem in right angled triangle sum of square of two sides is equal to the square of it's hypotenuse.
using pythagoras theorem
a^2 + b^2 = c^2
9^2 + 16^2 = 25^2
81 + 256 = 625
337 = 625
since sum of square of two smallest sides of a triangle is not equal to the square of it's hypotenuse it can be concluded that the given figure does not form right angle triangle.

Graph the Image of square KLMN after a translation 3 units left .
Answer:
N' (-8,9) K' (-8,3) L' (-2,3) M' (-2,9)
Step-by-step explanation:
To translate the square 3 units to the left you would subtract 3 from the x-coordinates of the points shown.
The coordinates of the translated square KLMN is given by K' (-8,3) L' (-2,3) M' (-2,9) N' (-8,9)
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
Given data ,
Let the square be represented as KLMN
Now , the coordinates of the square KLMN is
K ( -5 , 3 ) L ( 1 , 3 ) M' ( 1 , 9 ) N' ( -5 , 9 )
Now , let the translated square be represented as K'L'M'N'
When translating the square to three units to the left , the x coordinate of the square gets reduced by 3
So , the new coordinate of the square will be ( x - 3 , y )
Substituting the values in the equation , we get
K' = K ( -5 - 3 , 3 )
L' = L ( 1 - 3 , 3 )
M' = M ( 1 - 3 , 9 )
N' = N ( -5 - 3 , 9 )
So , on simplifying the equation , we get
The translated square is K' (-8,3) L' (-2,3) M' (-2,9) N' (-8,9)
Hence , the translated square is K' ( -8,3 ) L' ( -2,3 ) M' ( -2,9 ) N' ( -8,9 )

Answer:
J. 2085
Step-by-step explanation:
Fill in the desired value for y and solve for x.

Name/ Uid:1. In this problem, try to write the equations of the given surface in the specified coordinates.(a) Write an equation for the sphere of radius 5 centered at the origin incylindricalcoordinates.(b) Write an equation for a cylinder of radius 1 centered at the origin and running parallel to thez-axis inspherical coordinates.
To find:
(a) Equation for the sphere of radius 5 centered at the origin in cylindrical coordinates
(b) Equation for a cylinder of radius 1 centered at the origin and running parallel to the z-axis in spherical coordinates
Solution:
(a) The equation of a sphere with center at (a, b, c) & having a radius 'p' is given in cartesian coordinates as:
[tex](x-a)^{2}+(y-b)^{2}+(z-c)^{2}=p^{2}[/tex]
Here, it is given that the center of the sphere is at origin, i.e., at (0,0,0) & radius of the sphere is 5. That is, here we have,
[tex]a=b=c=0,p=5[/tex]
That is, the equation of the sphere in cartesian coordinates is,
[tex](x-0)^{2}+(y-0)^{2}+(z-0)^{2}=5^{2}[/tex]
[tex]\Rightarrow x^{2}+y^{2}+z^{2}=25[/tex]
Now, the cylindrical coordinate system is represented by [tex](r, \theta,z)[/tex]
The relation between cartesian and cylindrical coordinates is given by,
[tex]x=rcos\theta,y=rsin\theta,z=z[/tex]
[tex]r^{2}=x^{2}+y^{2},tan\theta=\frac{y}{x},z=z[/tex]
Thus, the obtained equation of the sphere in cartesian coordinates can be rewritten in cylindrical coordinates as,
[tex]r^{2}+z^{2}=25[/tex]
This is the required equation of the given sphere in cylindrical coordinates.
(b) A cylinder is defined by the circle that gives the top and bottom faces or alternatively, the cross section, & it's axis. A cylinder running parallel to the z-axis has an axis that is parallel to the z-axis. The equation of such a cylinder is given by the equation of the circle of cross-section with the assumption that a point in 3 dimension lying on the cylinder has 'x' & 'y' values satisfying the equation of the circle & that 'z' can be any value.
That is, in cartesian coordinates, the equation of a cylinder running parallel to the z-axis having radius 'p' with center at (a, b) is given by,
[tex](x-a)^{2}+(y-b)^{2}=p^{2}[/tex]
Here, it is given that the center is at origin & radius is 1. That is, here, we have, [tex]a=b=0,p=1[/tex]. Then the equation of the cylinder in cartesian coordinates is,
[tex]x^{2}+y^{2}=1[/tex]
Now, the spherical coordinate system is represented by [tex](\rho,\theta,\phi)[/tex]
The relation between cartesian and spherical coordinates is given by,
[tex]x=\rho sin\phi cos\theta,y=\rho sin\phi sin\theta, z= \rho cos\phi[/tex]
Thus, the equation of the cylinder can be rewritten in spherical coordinates as,
[tex](\rho sin\phi cos\theta)^{2}+(\rho sin\phi sin\theta)^{2}=1[/tex]
[tex]\Rightarrow \rho^{2} sin^{2}\phi cos^{2}\theta+\rho^{2} sin^{2}\phi sin^{2}\theta=1[/tex]
[tex]\Rightarrow \rho^{2} sin^{2}\phi (cos^{2}\theta+sin^{2}\theta)=1[/tex]
[tex]\Rightarrow \rho^{2} sin^{2}\phi=1[/tex] (As [tex]sin^{2}\theta+cos^{2}\theta=1[/tex])
Note that [tex]\rho[/tex] represents the distance of a point from the origin, which is always positive. [tex]\phi[/tex] represents the angle made by the line segment joining the point with z-axis. The range of [tex]\phi[/tex] is given as [tex]0\leq \phi\leq \pi[/tex]. We know that in this range the sine function is positive. Thus, we can say that [tex]sin\phi[/tex] is always positive.
Thus, we can square root both sides and only consider the positive root as,
[tex]\Rightarrow \rho sin\phi=1[/tex]
This is the required equation of the cylinder in spherical coordinates.
Final answer:
(a) The equation of the given sphere in cylindrical coordinates is [tex]r^{2}+z^{2}=25[/tex]
(b) The equation of the given cylinder in spherical coordinates is [tex]\rho sin\phi=1[/tex]
