To find the pmf of (y1|u = u), where u is a nonnegative integer, we need to use the Poisson distribution. The Poisson distribution describes the probability of a given number of events occurring in a fixed interval of time or space, given that these events occur independently and at a constant average rate. The pmf of (y1|u = u) can be expressed as: P(y1=k|u=u) = (e^-u * u^k) / k! where k is the number of events that occur in the fixed interval, u is the average rate at which events occur, e is Euler's number (approximately equal to 2.71828), and k! is the factorial of k. Therefore, the named distribution for the pmf of (y1|u = u) is the Poisson distribution, with parameter u representing the average rate of events occurring in the fixed interval.
About Poisson DistributionIn probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of the number of events occurring in a given time period if the average of these events is known and in independent time since the last event.

Answer:
y = 3x + 2
Step-by-step explanation:
1. Work out the gradient of the line segment: change in y/change in x: -2 - -6/ -8 - 4 = 4/-12 = -1/3
2. Work out the gradient of the perpendicular bisector: the gradient of the line segment and the perpendicular bisector should multiply to get -1. This means that we can do -1 ÷ -1/3 to work out the gradient which is 3
4. Find the midpoint of the line segment: (-8 + 4) ÷ 2 = -2, and (-2 + -6) ÷ 2 = -4, so the midpoint is (-2, -4)
3. The equation will be in the format y = 3x + c and will go through (-2, -4), so we can substitute those values into the equation to find c:
y = 3x + c-4 = 3(-2) + c-4 = -6 + cc = -4 + 6c = 2The equation of the line is y = 3x + 2

a cabinet holds shelves that are 12 1/2 inches apart. On one shelf, Katherine stacked a CD player that is 4 5/8 in. high on top of an amplifier that is 6 3/4 in. high. How much space was left above the CD player?
The space left above the CD player of height 4 5/8 in. stacked on the amplifier of height 6 3/4 in. in the cabinet which has shelves of 12 1/2 in. apart calculated as mixed fractions is 1 1/8 inches.
What is a mixed fraction?A mixed fraction is a fraction that is specified using the value of the quotient (the whole number part) and a fraction consisting of the remainder divided by the divisor.
The distance between the shelves of the cabinet = 12 1/12 inches
The height of the amplifier on a shelve of the cabinet on top of which Katherine stacks the CD player = 6 3/4 inches
The height of the CD player placed on top of the amplifier = 4 5/8 inches
The dimensions of the distance between the shelves and the heights of the CD player and amplifier are specified in fractions.
The space left above the CD player can be found in fractions as follows;
The combined height of the CD player and the amplifier is therefore;
[tex]H = 4\frac{5}{8} +6\frac{3}{4} = (4 + 6) + \left(\dfrac{5}{8}+\dfrac{3}{4} \right)[/tex]

[tex]10 + \dfrac{11}{8} = 10 + 1\dfrac{3}{8} = 11\frac{3}{8}[/tex]
The space above the CD player is therefore;
[tex]12\frac{1}{2} - 11\frac{3}{8} = 12 - 11 + \left(\dfrac{1}{2} - \dfrac{3}{8} \right) = 1 + \left(\dfrac{4 - 3}{8} \right)[/tex]

Perpendicular is an angle of 90° to a given line, plane, or surface means.
the equation is : y = ax+b
the equation is : y = ax+b
the slope is a : a×(1/4) = -1......( perpendicular to a line with a slope of 1/4) because
y=x/4 -2 means y = (1/4)x -2... the slope is : 1/4
but : a×(1/4) = -1 so : a = - 4 y= - 4x+b
the line that passes through (4, -1)
-1 =-4(4)+b
b = 15
the equation is : y = - 4x+15
It is a property of exponents that if ax = ay and a is not 0 or 1, then x = y. You used this property to solve the equation in Question 1. Now use this same property to solve the equation 3x = 729 by rewriting to get a common base number
Using the property of exponents, the value of x for the formula 3x=729 is 6.
What is exponents?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal 23. Keep in mind that a number raised to the power of one is itself. Exponentiation is the process of expressing huge numbers in terms of powers. That is, exponent refers to the number of times a number has been multiplied by itself. For example, 6 is multiplied by itself four times, yielding 6 6 6 6. This is written as 64. The exponent is 4 and the base is 6.

A company produced 600 parts during first shift. The second shift produced 564 parts.
What is the percent change from first to second shift?
Reduced by 6%
In the first shift, they purchased 600 parts
the second time they purchased 564 parts
Percent = output/ total* 100here the second year they purchased a percentage
-> second shift/first shift*100 of the first year
564/600*100 ---> 564/6which gives 94%so it shows there is a reduction of 100-94 = 6%
As the second shift purchased 94 of them as compared to 100 in the first shift, So by this we can draw the inference that there is a drop of 6%.
Percent is the number out of 100 so here 36 parts are less than in the case of 600 which shows 6%. Moreover, the percentage gives a clear idea in terms of 100 which is more familiar as compared to their figures.

Calculate the geometric mean return of the following data set: (Negative value should be indicated by a minus sign. Round your intermediate calculations to 4 decimal places and final answer to 2 decimal places.)
The geometric mean return of the given data set is 0.02.
The geometric mean return measures the compound rate of return over a period of time. It is calculated by taking the product of all the returns and then taking the nth root of the product, where n is the number of returns.
Formula: GMR = ((1+r1)(1+r2)…(1+rn))^1/n – 1
In this case, the data set is as follows:
r1 = 0.05
r2 = 0.03
r3 = -0.02
Using the formula above, the geometric mean return is calculated as:
GMR = ((1+0.05)(1+0.03)(1-0.02))^1/3 - 1
GMR = ((1.05)(1.03)(0.98))^1/3 - 1
GMR = (1.1394)^1/3 - 1

What is a polygon?
In geometry, a polygon is any closed curve made up of a series of line segments (sides) joined so that no two segments cross. Triangles (three sides), quadrilaterals (four sides), and pentagons are the simplest polygons (five sides).
The shape ABCDE forms a petagon.
The interior angle of a pentagon is 108°
The interior angle of a hexagon is 120°.
The ∠ABC is an angle of a regular hexagon, thus ∠ABC = 120°.
The ∠BCD is the angle of a regular hexagon, thus ∠BCD =120°.
The ∠BAE is an angle of a regular pentagon, thus ∠BAE=108°.
The ∠AED is an angle of a regular pentagon, thus ∠AED=108°.
The sum of all interior angle of a pentagon is 540°
Therefore,
∠ABC + ∠BCD + ∠BAE + ∠AED +∠EDC = 540°
120° + 120° + 108° + 108° + y = 540°

The side of a box has an area of 20 square inches and a height of 5 inches. How many inches is the width of the box?
For what value of k do the equation 3x 8y 0 and 6x Ky =- 16 represent coincident lines?
For what value of k = -48 the equation 3x 8y 0 and 6x Ky =- 16 represent coincident lines.
The equation 3x + 8y = 0 and 6x + Ky = -16 represent coincident lines when the two lines are identical, or when their slope and y-intercept are the same.
To find the value of k for which this is true, we can set the two equations equal to each other and solve for k.
3x + 8y = 0
6x + Ky = -16
The equation 3x + 8y = 0 represents the slope-intercept form of a line, where the slope is -3/8 and the y-intercept is 0.
The equation 6x + Ky = -16 represents the general form of a line, where the slope is -K/6 and the y-intercept is -16/K.
To find the value of k for which the two lines are identical, we need to make the slopes and y-intercepts equal.
-3/8 = -K/6
0 = -16/K
Solving for K, we get:
K = -48
So the lines are coincident when K = -48
