4. Train arrived late once on 7th day according to the simulation.

5. The probability that the train will arrive late on 3 or more of 20 days is 0.30.

6. There is no convincing evidence that New Jersey Transit's claim is false.

What is a simulation?

Simulation is the imitation of chance behavior, based on a model that accurately reflects the situation.

The dot at 7 represents that on the 7th day the train arrived late once.

Assuming the probability that each train is late is 0. 1, the estimate of the probability that that train is late on 3 or more of 20 days is -

30/100 = 0.30.

Since, the actual result is that train is late 17 times on 3 days so the result will be 0.17. But since these are just simulations and real-life incidents there is no proper evidence.

Therefore, the train company's claim is not entirely false.

The equation of line that passes through (5,-7) and is perpendicular to  y = 5/2 x - 6 is y = (-2/5)x - 5.

The slope-intercept form is expressed as;

y = mx + b

Where m is slope and b is the y-intercept.

Given the equation of the original line

y = (5/2)x - 6

Using the slope intercept, slope m is 5/2

Now, the equation of a perpendicular line to y = (5/2)x - 6 must have a slope that is the negative reciprocal of the original slope.

Slope of perpendicular line = -1 / ( 5/2 )

Slope of perpendicular line = -2/5

Plug the slope m = -2/5 and point (5,-7) into point-slope formula and simplify.

( y - y₁ ) = m( x - x₁ )

( y - (-7) ) = -2/5( x - 5 )

( y + 7 ) = -2/5( x - 5 )

y + 7 = (-2/5)x - (-2/5)(5)

y + 7 = (-2/5)x + (2)

y + 7 = (-2/5)x + 2

y = (-2/5)x + 2 - 7

y = (-2/5)x - 5

Therefore, the equation of the perpendicular line is y = (-2/5)x - 5.

Answer:

False. Functions can be compared even if they are not represented in the same form. For example, you can compare the rate of change of a function represented by a graph with the rate of change of a function represented by a table of values, as long as you have a way to compare the two.

True. Any function can be represented in a variety of different forms, including as a graph, a table of values, or an equation.

False. To compare the rate of change of a function represented in a graph with the rate of change of a function represented as a pair of points, you need to find the slope of the line formed by the two points, not the graph.

True. The y-intercept of a function represented by an equation in slope-intercept form can be compared to the y-intercept of a function represented by a graph. The y-intercept of a function is the point where the function crosses the y-axis, and it can be identified in both a graph and an equation in slope-intercept form.

The value of WX is 3 units.

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

For example if the ages of 10 set of students are 12,14,10,18,9,11,10,17,18,20. The range of their ages is the highest age - the lowest age = 20- 9 = 11.

A number line is a horizontal line that has equally spread number increments. In the number line the highest value is 1 and the lowest value is -2.

From range = highest value- lowest value

range = WX

therefore WX = 1-(-2)

According to the best calculations of scientists, the universe is 13.8 billion years old. However, we are not totally certain of its age, as we are with so many of the largest-scale characteristics of the cosmos. The cosmos may be as young as 11.4 billion years old, according to two opposing estimations based on two competing measures of its rate of expansion.

Finding the oldest star and working backwards from there using what we know about how stars are generated would be the simplest method to determine the age of the universe.

The first step to find the inverse of f(x) = 5x - 2 is to interchange both the x-value and y-value.

In Mathematics, an inverse function simply refers to a type of function that is obtained and generated by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of this function f(x) = 5x - 2, we would interchange both the input value (x) and output value (y) as follows:

f(x) = 5x - 2

y = 5x - 2

x = 5y - 2

Adding 2 to both sides of the equation, we have the following:

x + 2 = 5y - 2 + 2

5y = x + 2

Dividing both sides of the equation by 5, we have the following:

y = x/5 + 0.4 or (x + 2)/5

In the interval notation, the answer is [-5, ∞), for both x 0 and x -5.

When representing numbers between two numbers, either excluding or including the numbers, depending on the need, interval notations are employed. We employ the four interval notations shown below:

All digits from [a, b] up to and including both a and b.

All numbers between a and b, but not including an or b.

All numbers in the range (a, b), omitting a but including b.

[a, b] All numbers in the range [a, b], inclusive of a but exclusive of b.

The answer for x 0 and x -5 must be expressed using interval notation.

Each inequality is initially expressed in interval notation:

All numbers larger than 0—including 0—have the value x. This can be expressed as [0, ∞) in interval notation. Because is ambiguous, we omit it.

All numbers greater than -5, including -5, are expressed as x -5 x. This can be represented as [-5, ] in interval notation. Because is ambiguous, we omit it.

Now, we must find a solution for x 0 or x -5. Since the answer is "or," we take the unions of the two sets, hence the answer is:

[0, ∞) ∪ [-5, ∞) = [5, ∞).

The answer in interval notation for x 0 and x -5 is therefore [-5, ∞).

The slope of the line that contains the points (1,-9) and (-3,3) is -3 when the slope is y₂-y₁/x₂-x₁.

Given that,

We have two points they are (1,-9) and (-3,3).

We have to find the slope of the line that contains the points.

We know that,

The slope or steepness of a line is determined using the slope formula. It may be used to calculate any line's slope by comparing the change in the y-axis to the change in the x-axis. The slope of a line is the ratio of the change in the line's "y" coordinate to the change in its "x" coordinate.

Slope = y₂-y₁/x₂-x₁

So,

The points (1,-9) and (-3,3).

Slope = 3-(-9)/-3-1 = 3+9/-3-1 = 12/-4 = -3
