Step-by-step explanation:

The length of the rectangle is 7 cm and the width is 5 cm.

The whole distance covered by the rectangle's borders or its sides is known as its perimeter. As we know the rectangle will have 4 sides then the perimeter of the rectangle will be equal to the total of its four sides. And the unit will be in meters, centimeters, inches, feet, etc.        

The formula for the Perimeter of the rectangle is given by

Here we have

The length of a rectangle is 2cm greater than the width of the rectangle

And perimeter of the rectangle = 24 cm

Let x be the width of the rectangle

From the given data,

Length of the rectangle = (x + 2) cm  

As we know Perimeter of rectangle = 2(Length+width)

=> Perimeter of rectangle = 2(x+2 + x) = 2(2x +2)

From the given data,

Perimeter of rectangle =  24cm

=> 2(2x +2) = 24 cm

=> (2x +2) = 12     [ Divided by 2 into both sides ]

=>  2x = 12 - 2

=>  2x = 10

=>   x = 5         [ divided by 2 into both sides ]  

Length of rectangle, (x+2) = 5 + 2 = 7 cm

Therefore,

The length of the rectangle is 7 cm and the width is 5 cm.

(a) The equation z = z^2 does not have a well-defined graph. (b) The equation y² + 2² = 1 + x² represents a cylinder with radius 2 and its axis parallel to the z-axis.

(a) The equation z = z^2 represents a paraboloid.

To sketch the graph of this equation, we can plot some points and observe the shape of the paraboloid. However, it's important to note that the equation z = z^2 is not a well-defined equation as it leads to multiple interpretations and can cause mathematical inconsistencies. The equation implies that z is equal to either 0 or 1, but it does not specify a specific relationship between x, y, and z.

(b) The equation y² + 2² = 1 + x² represents a cylinder.

To sketch the graph of this equation, we can treat it as a three-dimensional equation and interpret it as a cylinder. The equation implies that the sum of the squares of y and 2 is equal to 1 plus the square of x. This equation describes a right circular cylinder with its axis parallel to the z-axis and centered at the origin. The radius of the cylinder is 2, and it extends infinitely in the positive and negative directions along the x-axis. The graph would be a cylinder with circular cross-sections.

Answer:

p = 7.5

Step-by-step explanation:

(2/3)p = 5

2p/3 = 5

3x-1 of the following must be odd .The correct  option (d) .

The properties of odd and even integers. An integer is even if it is divisible by 2, and odd if it is not divisible by 2.

Let's simplify the given equation: x = 50y + 69
We can rewrite this as: x = (49y + 50y) + 19

Notice that 49y + 50y is an even integer (since it is the sum of two even integers) and adding 19 to an even integer will result in an odd integer. Therefore, x is always odd.

Now, let's look at each option:

a. xy = (50y + 69)y = 50y^2 + 69y
This could be either even or odd, depending on the value of y.

b. x + y = (50y + 69) + y = 51y + 69
This could be either even or odd, depending on the value of y.

c. x + 2y = (50y + 69) + 2y = 50y + 2y + 69 = 52y + 69
This could be either even or odd, depending on the value of y.

d. 3x - 1 = 3(50y + 69) - 1 = 150y + 206
This must be odd, because an odd integer (3) multiplied by an odd integer (x) and then subtracting an odd integer (1) will always result in an odd integer.

e. 3x + 1 = 3(50y + 69) + 1 = 150y + 208
This could be either even or odd, depending on the value of y.

Therefore, the only option that must be odd is (d) 3x - 1.

The equation that represents the sentence "one-half the sum of a number and four is three less than the quotient of five and the number" is 1/2n + 4 = 5/n - 3 (option d).

Let's break down the sentence to understand the equation.

"One-half the sum of a number and four" can be represented as 1/2(n + 4). Here, n represents the number.

"Is three less than the quotient of five and the number" can be represented as 5/n - 3.

Combining the two parts, we have:

1/2(n + 4) = 5/n - 3.

This equation states that half the sum of a number and four is equal to three less than the quotient of five and the number.

Option d) 1/2n + 4 = 5/n - 3 correctly represents this relationship. It accounts for the division of 5 by n and subtracts 3, while also adding the number n to 4 and dividing the sum by 2.

Answer:

To find the distance, we can set up an equation based on the given information. Let's assume the distance to town is represented by "d."

Since Mr. Johnson drove at 18 mph, we can express the time it took for him to reach town as "d/18."

Mr. Smith, on the other hand, biked at 12 mph, and it took him 3 hours longer than Mr. Johnson to reach town. Therefore, we can express the time it took for Mr. Smith as "d/12 + 3."

Setting up an equation, we have:

d/18 = d/12 + 3

To solve for "d," we can multiply both sides of the equation by the least common multiple (LCM) of 18 and 12, which is 36. This gives us:

2d = 3d + 108

Simplifying further, we find:

d = 108

Hence, the distance of the route to town is 108 units.

The probability distribution for the random variable X, representing the number of defective microchips in a sample of three:

X = 0: Probability of selecting 3 non-defective microchips out of 15 (5/15) * (4/14) * (3/13) = 60/364 ≈ 0.165

X = 1: Probability of selecting 2 non-defective and 1 defective microchip out of 15 [(5/15) * (4/14) * (10/13)] + [(5/15) * (10/14) * (4/13)] + [(10/15) * (5/14) * (4/13)] = 240/364 ≈ 0.659

X = 2: Probability of selecting 1 non-defective and 2 defective microchips out of 15 [(5/15) * (10/14) * (9/13)] + [(10/15) * (5/14) * (9/13)] + [(10/15) * (9/14) * (5/13)] = 240/364 ≈ 0.659

X = 3: Probability of selecting 3 defective microchips out of 15 (10/15) * (9/14) * (8/13) = 720/364 ≈ 1.978

The first paragraph provides a summary of theprobability distribution for X. It states that when selecting a sample of three microchips from the box containing 15 microchips, the random variable X can take on values of 0, 1, 2, or 3, representing the number of defective microchips in the sample. The probabilities for each value of X are approximately 0.165, 0.659, 0.659, and 1.978, respectively.

The second paragraph explains how the probabilities are calculated. To find the probability of X = 0, we multiply the probabilities of selecting three non-defective microchips from the 15 available. For X = 1 and X = 2, we consider the combinations of selecting two non-defective and one defective microchip from the 15 available, using the formula for combinations. Finally, for X = 3, we calculate the probability of selecting three defective microchips from the 15 available. By summing up the probabilities for each value of X, we obtain a probability distribution that represents the likelihood of each possible outcome.

To express the volume in cubic inches, we first need to convert from liters to cubic centimeters (\(cm^{3}\)) using the conversion 1l = 1000\(cm^{3}\).

Volume in \(cm^{3}\) = 5.2l x 1000\(cm^{3}\)/l = 5200\(cm^{3}\)

Next, we can use the conversion 1in = 2.54cm to convert from \(cm^{3}\) to cubic inches.

Volume in cubic inches = 5200\(cm^{3}\) x \((1 in/2.54cm)^3\)= 317.01 \(in^3\) (rounded to two decimal places)

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:
