Write the equation of a line passing through the points (5,5) and (8,11).
1. y = 2x + 5
2. y = 1/3 x + 7
3. y = 2x - 5
4. y = -2x + 15

Answers

Answer 1

The equation of a line passing through the points (5,5) and (8,11) is

3) y = 2x-5.

What is equation?

When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).   It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.

Here the given two points are \((x_1,y_1)=(5,5)\) and \((x_2,y_2)=(8,11)\) .

Now using slope formula then,

=> slope m = \(\frac{y_2-y_1}{x_2-x_1}\) = \(\frac{11-5}{8-5} =\frac{6}{3} = 2\)

Now using equation formula then \(y-y_1=m(x-x_1)\)

=> y-5=2(x-5)

=> y-5 = 2x-10

=> y = 2x-10+5

=> y = 2x-5

Hence the equation is 3) y = 2x-5.

How would you describe the following events, of randomly drawing a King OR a card
with an even number?

a) Mutually Exclusive

b)Conditional

c)Independent

d)Overlapping

Answers

Events, of randomly drawing a King OR a card with an even number describe by a) Mutually Exclusive.

The events of randomly drawing a King and drawing a card with an even number are mutually exclusive. This means that the two events cannot occur at the same time.

In a standard deck of 52 playing cards, there are no Kings that have an even number.

Therefore, if you draw a King, you cannot draw a card with an even number, and vice versa.

The occurrence of one event excludes the possibility of the other event happening.

It is important to note that mutually exclusive events cannot be both independent and conditional. If two events are mutually exclusive, they cannot occur together, making them dependent on each other in terms of their outcomes.

The correct option is (a) Mutually Exclusive.

1) The position function of a crazy cat is s(t)=1³-15t²+631, 0 ≤t≤8, where s is in metres, and t is in seconds. Consider any positive movement by the cat to be forward. a) Find the velocity v(t)

Answers

The instantaneous velocity is v(t) = 3t² - 30t

How to find the velocity function?

To find the velocity function, we need to take the derivative of the position function with respect to time.

The velocity function represents the rate of change of position with respect to time. Let's find the derivative of the position function step by step:

Given: s(t) = t³ - 15t² + 631

Take the derivative of each term with respect to time (t):

  s'(t) = d/dt(t³) - d/dt(15t²) + d/dt(631)

Apply the power rule of differentiation:

  Recall that the power rule states that d/dx(x^n) = nx^(n-1).

  s'(t) = 3t² - 30t + 0

Simplify the derivative:

  s'(t) = 3t² - 30t

The velocity function, v(t), is given by the derivative of the position function. Therefore, the velocity function for the given position function s(t) = t³ - 15t² + 631 is:

v(t) = 3t² - 30t

This represents the instantaneous velocity of the crazy cat at any given time t between 0 and 8 seconds.

simpfly 3 to the 10 power over 3 to the 5 power times 3 to the 8 power also the first part is done i just need the exponet

Answers

The exponent of 3 in the simplified expression is -3.

How to solve

The expression you've provided is \((3^{10)} / (3^5 * 3^8)\).

This can be simplified by using the properties of exponents, particularly the rule that says when you divide with the same base, you subtract the exponents.

Moreover, if you have a common base and want to multiply, you simply sum the corresponding exponents.

Thus, it is possible to alter your wording into the following form:

\(3^(10) / 3^{(5+8)\)

Then, this simplifies to:

\(3^{(10)} / 3^{(13)}\)

Now you subtract the exponents:

Which is the concept of linear systematic sampling. So, the answer is Systematic.

What is Linear systematic sampling ?

Linear systematic sampling is a method of systematic sampling in which samples are not repeated at the end and 'n' units are chosen to be a part of a sample with 'N' population units. Rather than choosing these 'n' units of a sample at random, a researcher can use skip logic to do so.Because systematic sample units are uniformly distributed across the population, systematic sampling should be used only if the given population is logically homogeneous. The researcher must ensure that the sampling interval chosen does not obscure a pattern. Any pattern would jeopardize the randomness.

find the general solution of the given higher-order differential equation. d 4y dx4 − 2 d 2y dx2 − 8y = 0

Answers

he required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Let’s assume the general solution of the given differential equation is,

y=e^{mx}

By taking the derivative of this equation, we get

\(\frac{dy}{dx} = me^{mx}\\\frac{d^2y}{dx^2} = m^2e^{mx}\\\frac{d^3y}{dx^3} = m^3e^{mx}\\\frac{d^4y}{dx^4} = m^4e^{mx}\\\)

Now substitute these values in the given differential equation.

\(\frac{d^4y}{dx^4}-2\frac{d^2y}{dx^2}-8y\\=0m^4e^{mx}-2m^2e^{mx}-8e^{mx}\\=0e^{mx}(m^4-2m^2-8)=0\)

Therefore, \(m^4-2m^2-8=0\)

\((m^2-4)(m^2+2)=0\)

Therefore, the roots are, \(m = ±\sqrt{2} and m=±2\)

By applying the formula for the general solution of a differential equation, we get

General solution is, \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

Hence, the required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

A campus radio station surveyed 500 students to determine the types of music they like. The survey revealed that 204 like rock,164 like country, and 129 like jazz. Moreover, 24 like rock and country, 29 like rock and jazz, 29 like country and jazz, and 9 like all three types of music. How many students surveyed liked exactly one of the three types of music

Answers

There were 360 students surveyed who liked exactly one of the three types of music means that out of the total number of students surveyed, 360 of them expressed a preference for only one of the three music types.

To find the number of students who liked exactly one of the three types of music, we need to subtract the students who liked two or three types of music from the total number of students who liked each individual type of music.

Let's define:

R = Number of students who like rock

C = Number of students who like country

J = Number of students who like jazz

Given the information from the survey:

R = 204

C = 164

J = 129

We also know the following intersections:

R ∩ C = 24

R ∩ J = 29

C ∩ J = 29

R ∩ C ∩ J = 9

To find the number of students who liked exactly one type of music, we can use the principle of inclusion-exclusion.

Number of students who liked exactly one type of music =

(R - (R ∩ C) - (R ∩ J) + (R ∩ C ∩ J)) +

(C - (R ∩ C) - (C ∩ J) + (R ∩ C ∩ J)) +

(J - (R ∩ J) - (C ∩ J) + (R ∩ C ∩ J))

Plugging in the given values:

Number of students who liked exactly one type of music =

(204 - 24 - 29 + 9) + (164 - 24 - 29 + 9) + (129 - 29 - 29 + 9)

= (160) + (120) + (80)

Answers

A measure of central tendency refers to a statistical measure that summarizes or represents the center or typical value of a dataset. It provides a single value that represents the central or average value of the data.

In more detail, option b is the correct answer. A measure of central tendency, such as the mean, median, or mode, allows a reader to summarize a dataset with one datum point. These measures provide information about the typical value or the central position of the data distribution.

The mean is calculated by summing all the values in the dataset and dividing by the number of data points. The median is the middle value when the data is arranged in order, and the mode is the value that appears most frequently in the dataset.

By using a measure of central tendency, readers can gain insight into the overall trend or central value of a dataset without having to examine every individual data point. It simplifies the understanding and interpretation of data by providing a concise summary that represents the central tendency of the data distribution.

At what time will her book hit the ground?

Answers

Given statement solution is :-Time cannot be negative in this context, we discard the solution t = -1,  the book will hit the ground after approximately 2.5 seconds.

To find the time when the book hits the ground, we need to determine when the height (h) becomes zero. We can set up the equation and solve for t.

The equation given is:

h = -\(16t^2 + 24t + 40\)

Setting h = 0, we have:

0 = \(-16t^2 + 24t + 40\)

Now we can solve this quadratic equation. There are a few methods to solve quadratic equations, such as factoring, completing the square, or using the quadratic formula. In this case, we'll use the quadratic formula:

t = \((-b ± √(b^2 - 4ac)) / (2a)\)

For our equation, a = -16, b = 24, and c = 40. Plugging these values into the quadratic formula, we get:

t = \((-24 ± √(24^2 - 4*(-16)40)) / (2(-16))\)

t = \((-24 ± √(576 + 2560)) / (-32)\)

t = (-24 ± √3136) / (-32)

t = (-24 ± 56) / (-32)

Now we have two possible solutions:

t = (-24 + 56) / (-32) = 32 / (-32) = -1

t = (-24 - 56) / (-32) = -80 / (-32) = 2.5

Since time cannot be negative in this context, we discard the solution t = -1. Therefore, the book will hit the ground after approximately 2.5 seconds.

Now, we need to solve the equation for x. To do so, we want x to be by itself on one side of the equation. We will use inverse operations to get the x by itself. First, subtract 3 from either side to under the +3 on the right side of the equation.

-1 - 3 = 1/4x + 3 - 3

-4 = 1/4x

Next, we will divide by 1/4 to undo the *1/4. Dividing by 1/4 is the same as multiplying by 4, so we will multiply each side by 4.

The probability that exactly 5 out of the first 12 customers buy a magazine is 0.139.

The probability that exactly 5 out of the first 12 customers buy a magazine assuming his suspicion that 7.5% of his customers buy a magazine is correct is 0.139.

Here's how to solve it:

First, we note that we have a binomial distribution since we are counting the number of "successes" (people buying magazines) out of a fixed number of trials (12 customers).

We can use the formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where

P(X = k) is the probability of getting k successes,

n is the number of trials,

p is the probability of success, and

C(n, k) is the binomial coefficient "n choose k".

We can plug in the values we have:

P(X = 5) = C(12, 5) * 0.075^5 * (1 - 0.075)^(12 - 5)

where

C(12, 5) = 792 is the number of ways to choose 5 out of 12 customers.

Evaluating this expression gives:

P(X = 5)

≈ 0.139

So the probability that exactly 5 out of the first 12 customers buy a magazine is 0.139.
