This is the required probability density function for Z.

Since the task is complete only when the computation at both worker nodes is complete, the total time for completion of the task is the maximum of X and Y.

Therefore, we have:

Z = max(X,Y)

The CDF of Z can be written as:

\(F_Z(z)\) = P(Z <= z) = P(max(X,Y) <= z)

Since X and Y are independent, we have:

P(max(X,Y) <= z) = P(X <= z, Y <= z)

Using the properties of exponential distribution, we have:

P(X <= z, Y <= z) = P(X <= z) * P(Y <= z)

\(= (1 - e^{-l1 * z}) * (1 - e^{-l2 * z})\)

Therefore, the CDF of Z is:

\(F_Z(z) = (1 - e^(-l1 * z)) * (1 - e^(-l2 * z))\)

To find the PDF of Z, we differentiate the CDF with respect to z:

\(f_Z(z) = d/dz F_Z(z)\)

\(= l1 * e^{-l1 * z} * (1 - e^{-l2 * z}) + l2 * e^{-l2 * z} * (1 - e^{-l1 * z}) \\\)

Therefore, the PDF of Z is:

\(f_Z(z) = l1 * e^{-l1 * z} * (1 - e^{-l2 * z}) + l2 * e^{-l2 * z} * (1 - e^{-l1 * z})\)

The hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.

The following can be deduced from the information:

x1 = 275

x2 = 170

n1 = 500

n2 = 500

The sample proportion will be:

p1 = 275/500 = 0.55

p2 = 170/500 = 0.34

The pooled proportion will be:

= (275 + 170)/(500 + 500)

= 0.44

The test statistic is 6.681. It should be noted that the test statistics is a number that's calculated by a statistical test. It shows how the observed data are far from the null hypothesis.

The p value in this scenario is extremely small. The p value is a measurement used to validate a hypothesis against the observed data. Therefore, we have to reject the null hypothesis.

In this case, the hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.

Answer:

Pete: 39, Linda: 42

Step-by-step explanation:

Suppose Pete has x dollars. If he has 3 dollars less than Linda, then Linda has 3+x dollars. Together, they have 81 dollars:

x+3+x=81

2x+3=81

2x=78

x=39

Since Pete has x dollars, and x=39, he has $39.

Linda has 3+x, which is 39+3 = $42

One of the boards is 30 inches long and the other board is 12 inches longer so it has to be 42 inches long. The sum of the lengths of the two boards is 72 cm and one of the boards is 12 inches longer than the other.

Here,

A board is 72 cm in length and must be cut so that one piece is 12 cm longer than the other piece .

We have to find the leg of each piece.

What is Length, Width and height?

The length, width and  height of an object are the different dimensions in linear units. length is the longest side of a shape, width is the shorter side, and height is the vertical dimension of the shape.

Now,

If you're going to cut the 72 inch board into two pieces, you can call one of the pieces x units long.

And, since the other piece is 12 inches longer than your first piece, its length is x + 12.

And, when you place these two pieces back together, their lengths should add up to be 72 inches.

You can write this last statement about adding the two pieces together to get a 72 inch piece

In equation form as:

x + (x+12) = 72

2x + 12 = 72

To solve this begin by subtracting 12 from both sides;

2x = 60

Now just divide both sides by 2 to find that:

x = 30

So, one of the boards is 30 inches long and the other board is 12 inches longer so it has to be 42 inches long. The sum of the lengths of the two boards is 72 cm and one of the boards is 12 inches longer than the other.

The measure of angle A, B, C are 60°,60°,60°

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

The sum of angle in a polygon is 180°. i.e

A+B + C = 180°

therefore we can say that;

2x+2x + 3x-30 = 180

7x -30 = 180

7x = 180+30

7x = 210

divide both sides by 7

x = 210/7 = 30

The area of square A is 25 in² and each side measures 5 inches

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

For square B:

Area = side²

144 = side²

side = 12 in

For square C:

Area = side²

169 = side²

side = 13 in

To find the length of each square A side, we use Pythagoras theorem. Hence:

(Side C)² = (Side A)² + (side B)²

13² = (side A)² + 12²

169 = (side A)² + 144

(side A)² = 25

Side A = 5 in

Area of square A = (side A)² = 5² = 25 in²

The area of square A is 25 in²

The length of the rectangular  playground is 241.86 foot.

Given that area of rectangle is 19,500 sq.ft and length of rectangle is three times its width.The area for rectangle is given by formula: A=LW.

Now according to the given condition, L= 3W. Further we'll solve by putting L= 3W in the formula for rectangle.

A=LW

As given A= 19,500 sq.ft and considering L=3W,

19,500 = 3W*W

19,500 = 3W^2

∴ W^2 = 6500

∴ W = \(\sqrt{6500}\)

∴ W = 80.6225 ft. ≈ 80.62 ft.

Now putting the value W = 80.62 in equation L =3W,

L = 3* 80.62

L = 241.86 ft.

The length of the rectangular playground is 241.86 foot.

The quantities which are squares or multiple of linear things twice grow by square of scale factor. The volume of rectangular prism A = 64 m³

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.

So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.

So, area of first figure = k² × area of second figure

Similarly, Volume of first figure = k³ × volume of second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

Given that the Rectangular prism B is the image of rectangular prism A after dilation by a scale factor of 1/2.

Scale factor =  (Length of rectangular prism B)/(Length of rectangular prism A)

1/2 = (Length of rectangular prism B)/(Length of rectangular prism A)

Now, the volume of the rectangular prism can be written as,

(Scale factor)³ = (Volume of rectangular prism B)/(Volume of rectangular prism A)

(1/2)³ = 8 m³ /(Volume of rectangular prism A)

The volume of rectangular prism A = 64 m³

Hence, The volume of rectangular prism A = 64 m³

If the sample was randomly selected from the population but the subjects were not randomly assigned to treatments, it means that the study is an observational study rather than a randomized controlled trial (RCT).

In an observational study, researchers do not intervene or assign treatments to the participants. Instead, they observe and collect data on existing variables or treatments as they naturally occur. The subjects in the study are not deliberately manipulated or assigned to different groups.

This type of study design has limitations when it comes to establishing causality or making causal inferences.
