The slope of the line will be equal to -4/3.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is also defined as the ratio of the rise to the run.

Given that the two points are (2,3) and (8,-5). The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -5 - 3 ) / (  8 - 2 )

Slope = -8 / 6

Slope = -4 / 3

Therefore, the slope of the line will be equal to -4/3.

The equation of the line having slope 0 and passing through (-3,-2) is f(x) = -2.

Any horizontal line has the same y-value for every point on the line. We are given that the line passes through the point (-3,-2). This means that f(-3) = -2, since the y-value of the point (-3,-2) corresponds to the value of the function at x = -3.

This is because no matter what x-value we plug into the function, the output (y-value) will always be -2. Therefore, the equation of the line in function notation is f(x) = -2.

The value of x in the right angle placed is equal to 16

A right angle is an angle that measures 90 degrees. It is the most commonly seen angle in our day-to-day life. It can be seen in the corners of a room, the edges of boxes, the screen of a mobile phone, and so on. The sides of a square and a rectangle always form a right angle with each other. In radians, it is represented as π/2. Let us discuss more about a right angle in this article.

A right angle is an angle of 90°. When two rays intersect and form a 90˚ angle or are perpendicular to each other at the intersection, they are said to form a right angle.

In the given question, we can set an equation and find the value of x

90 = 26 + 4x

Lets solve for x

Answer:

Equation: y = -4x + 1

Slope: -4

Y-intercept: y = 1

Step-by-step explanation:

To find the equation of the line you need the gradient and the y-intercept

To find the gradient we need to divide the change in y by the change in x:

As the graph has a negative correlation the gradient would have a minus which is why it would be -4!

To find the y-intercept we need to find the number on the y-axis that the line crosses which in this case would be y = 1!!

Hope this helps, have a great day!!

Answer:

equation:y=4x+1

y-intercept:1

slope:4/1 or 4

Step-by-step explanation

the equation has to be in slope intercept form which is \(y=mx+b\) where m is the slope and b is the y-intercept. the y-intercept is when x is 0 in this case when x is 0 y is 1 (0,1) so the y-intercept is 1. the slope is rise/run so pick two points that cross the grid perfectly and count the units rise and run. this line rises 4 and runs 1 so the slope is 4/1 so 4 hence the equation \(y=4x+1\)

Answer:

y=4x+c now put (-3,7) into the equation to find the y intercept. 7=4×−3+c. 7=−12+c. c=19.

Step-by-step explanation:

y=mx++c is the general equation with m as the slope.

The circumference of the given circle is approximately 47.3 inches.

Since the length of the arc KL and the measure of the central angle ∠KOL are known, we can use the formula for arc length to find the circumference of the circle:

arc length = (central angle / 360°) x circumference

Plugging in the known values, we have:

4.6 in = (35° / 360°) x circumference

Solving for the circumference, we get:

circumference = 4.6 in / (35° / 360°)

circumference = 4.6 in x (360° / 35°)

circumference ≈ 47.3 in (rounded to the nearest tenth)

Therefore, the circumference of the circle is approximately 47.3 inches.

Step-by-step explanation:

The cost function is the sum of the costs as a function of the number of bins made.

C(x) = 4x + 18424

The profit function is the difference between the revenue and the cost functions.

P(x) = R(x) - C(x)

P(x) = -2x^2 + 478x - (4x + 18424)

P(x) = -2x^2 + 474x - 18424

The smallest break-even point is the smallest value of x at which profit is zero. Zero profit means there is no gain and no loss.

P(x) = -2x^2 + 474x - 18424 = 0

x^2 - 237x + 9212 = 0

9212 = 2^2 * 7^2 * 47

(x - 188)(x - 49) = 0

x - 188 = 0 or x - 49 = 0

x = 188 or x = 49

Answer: 49

The cost function is C(x) = 4x + 18424.

The profit function is P(x) = -2x² + 474x - 18424

The quantity at which there is the smallest break-even point is 49.

The cost function is the sum of the costs as a function of the number of bins made.

C(x) = 4x + 18424

The profit function is the difference between the revenue and the cost functions.

P(x) = R(x) - C(x)

P(x) = -2x² + 478x - (4x + 18424)

P(x) = -2x² + 474x - 18424

The smallest break-even point is the smallest value of x at which profit is zero. Zero profit means there is no gain and no loss.

P(x) = -2x² + 474x - 18424 = 0

x² - 237x + 9212 = 0

9212 = 2²(7²) 47

(x - 188)(x - 49) = 0

x - 188 = 0 or x - 49 = 0

The distribution of X can be modelled by a binomial distribution because

E. The trials are independent.

F.There are a fixed number of bids.

G. There is the same probability of success for each trial (bid).

H. The data are binary (you either win the bid or not, that is, success or failure).

b) The probability of winning exactly 1 bid = 0.4410

c) The probability that you win 1 bid or fewer = 0.7840

d) The probability that you win more than 1 bid = 0.2160

Step-by-step explanation:

Complete Question

You are bidding on three items available on an online shopping site. You think that for each bid you have a 30% chance of winning it, and the outcomes of the three bids are independent events. Let X denote the number of winning bids out of the three items you bid on.

a. Explain why the distribution of X can be modeled by the binomial distribution.

A. The trials are dependent.

B. The data are not binary.

C. Probabilities of success for trials (bids) differ for each trial

D. The number of bids varies.

E. The trials are independent

F.There are a fixed number of bids.

G. There is the same probability of success for each trial (bid)

H. The data are binary

b. The probability of winning exactly 1 bid is (Round to four decimal places as needed.)

c. Find the probability that you win 1 bid or fewer.

d. Find the probability that you win more than 1 bid.

Solution

a) A binomial experiment is one in which the probability of success doesn't change with every run or number of trials.

It usually consists of a fixed number of runs/trials with only two possible outcomes, a success or a failure. The outcome of each trial/run of a binomial experiment is independent of one another.

Hence, the correct options are

E. The trials are independent.

F.There are a fixed number of bids.

G. There is the same probability of success for each trial (bid).

H. The data are binary (you either win the bid or not, that is, success or failure).

b) Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

n = total number of sample spaces = total number of bids available = 3

x = Number of successes required = winning exactly 1

p = probability of success = probability of winning a bid = 30% = 0.30

q = probability of failure = probability of NOT winning a bid = 1 - p = 1 - 0.30 = 0.70

P(X = 1) = ³C₁ (0.3)¹ (0.7)³⁻¹ = 0.4410 to 4 d.p.

c) The probability that you win 1 bid or fewer.

n = total number of sample spaces = total number of bids available = 3

x = Number of successes required = winning 1 or fewer bid = ≤ 1 = 0, 1

p = probability of success = probability of winning a bid = 30% = 0.30

q = probability of failure = probability of NOT winning a bid = 1 - p = 1 - 0.30 = 0.70

P(X ≤ 1) = P(X = 0) + P(X = 1)

P(X = 0) = ³C₀ (0.3)⁰ (0.7)³⁻⁰ = 0.343

P(X = 1) = 0.441 (as calculated in (b) above)

P(X ≤ 1) = 0.343 + 0.441 = 0.784

d) Probability that you win more than 1 bid

n = total number of sample spaces = total number of bids available = 3

x = Number of successes required = winning more than 1 bid = >1 = 2, 3

p = probability of success = probability of winning a bid = 30% = 0.30

q = probability of failure = probability of NOT winning a bid = 1 - p = 1 - 0.30 = 0.70

P(X > 1) = P(X = 2) + P(X = 3)

P(X = 2) = ³C₂ (0.3)² (0.7)³⁻² = 0.189

P(X = 3) = ³C₃ (0.3)³ (0.7)³⁻³ = 0.027

P(X > 1) = 0.189 + 0.027 = 0.2160

\(f'(x)=36x^2(2x^3-4)^5\)

Step-by-step explanation:

The Chain Rule for Derivatives

Given a function y=f(u) and u=g(x), the derivative dy/dx is computed by using the chain rule:

\(y'=f'(u).u'(x)\)

We have:

\(f(x)=(2x^3-4)^6\)

It can be written as:

\(f(x)=u^6\)

Where:

\(u=2x^3-4\)

Thus:

\(f'(x)=(u^6)'(2x^3-4)'\)

\(f'(x)=6u^5(6x^2)\)
