Answer:

1 hr at the speed of 50 mph

Step-by-step explanation:

If you went 50 mph it would be 1 hour. 100mph = 30min.

The time it will take to cover a given a given distance of 50 miles, assuming a speed of 20 miles per hour is 2 hours 30 minutes

Given Data

Distance = 50 miles

We Need another parameter speed, this will help us determine the exact time it would take to travel given the distance

Let us assume a speed of 20 miles per hour

We know that the expression relating speed, distance and time is given as

Speed = Distance/Time

Substituting we have

20 = 50/t

solving for t we have

t = 50/20

t = 2.5 hours

This is the same as 2 hours 30 minutes

To complete the square and solve the quadratic equation, we can follow these steps: Move the constant term to the right side of the equation

Divide all terms by the coefficient of the x^2 term

Add the square of half the coefficient of the x term to both sides of the equation

Factor the left side of the equation as a perfect square trinomial

Take the square root of both sides of the equation

Solve for x .

Explanation:

To solve the quadratic equation 7 - 6x + 4x^2 = 3, we can complete the square using the following steps:

Step 1: Move the constant term to the right side of the equation:

4x^2 - 6x + 4 = 0 + 3

Step 2: Divide all terms by the coefficient of the x^2 term to make the coefficient equal to 1:

x^2 - (3/2)x + 1 = 0

Step 3: Add the square of half the coefficient of the x term to both sides of the equation:

x^2 - (3/2)x + (3/4)^2 = (3/4)^2 + 1

Step 4: Factor the left side of the equation as a perfect square trinomial:

(x - (3/4))^2 = (13/16)

Step 5: Take the square root of both sides of the equation:

x - (3/4) = ±(√13/4)

Step 6: Solve for x by isolating it on one side of the equation:

x = (3/4) ± (√13/4)

Therefore, the solutions to the quadratic equation 7 - 6x + 4x^2 = 3 are x = (3/4) + (√13/4) and x = (3/4) - (√13/4), which can be simplified to x ≈ 1.3 and x ≈ 0.2.

To find the area between the graphs of y = x - 17 and y = -2x + 14 over the interval 1 ≤ x ≤ 19, we need to find the intersection points first.

Setting the two equations equal to each other, we have:

x - 17 = -2x + 14

Simplifying the equation:

3x = 31

x = 31/3

The intersection point occurs at (31/3, (31/3) - 17).

To find the area, we integrate the difference of the two functions over the given interval:

Area = ∫(x - 17) - (-2x + 14) dx

= ∫(3x - 31) dx

Evaluating the integral over the interval 1 to 19 will give us the desired area between the graphs.

To determine if a data point is considered an outlier for a data set, we need to calculate the interquartile range (IQR) and use it to define the outlier boundaries. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). The correct option is (B).

We have that Q1 = 9 and Q3 = 17, we can calculate the IQR as follows:

IQR = Q3 - Q1 = 17 - 9 = 8

To identify outliers, we can use the following rule:

- Any data point that is less than Q1 - 1.5 * IQR or greater than Q3 + 1.5 * IQR is considered an outlier.

Using this rule, we can evaluate each data point:

A. 27: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

B. 17: This data point is not an outlier because it is equal to the third quartile (Q3).

C. 3: This data point is less than Q1 - 1.5 * IQR = 9 - 1.5 * 8 = -3. It is considered an outlier.

D. 41: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

Therefore, the outliers in the data set are A (27) and D (41).

As for when to use the mean, it is generally recommended to use the mean as a measure of central tendency when the data is symmetric and does not have extreme values.

Therefore, the correct option would be B. When the data is symmetric.

The slope-intercept equation for the line passing through the points (0, 2) and (5, 4) is y = (2/5)x + 2.

To find the slope-intercept equation for the line passing through the points (0, 2) and (5, 4), we can use the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

Where (x₁, y₁) represents one of the points on the line, and 'm' represents the slope of the line.

Using the points (0, 2) and (5, 4), we can choose either point as (x₁, y₁). Let's use the first point (0, 2).

Plugging in the values:

y - 2 = m(x - 0)

Simplifying further:

y - 2 = mx

Now, we need to find the value of 'm', the slope of the line. The slope is given by the change in y divided by the change in x between the two points:

m = (y₂ - y₁) / (x₂ - x₁)

Using the given points (0, 2) and (5, 4):

m = (4 - 2) / (5 - 0)

m = 2 / 5

Substituting this value back into the equation, we have:

y - 2 = (2/5)x

To convert this to slope-intercept form (y = mx + b), we can rearrange the equation:

y = (2/5)x + 2

Therefore, the slope-intercept equation for the line passing through the points (0, 2) and (5, 4) is y = (2/5)x + 2.

If we sample the function x(t) = cos(75t) at the Nyquist frequency, the resulting discrete frequency would be half of the Nyquist frequency, which is equal to half of the highest frequency component in the continuous signal.

In this case, the highest frequency component in x(t) is 75 Hz, as determined by the coefficient of t in the cosine function. According to the Nyquist-Shannon sampling theorem, to accurately represent a signal, the sampling frequency must be at least twice the highest frequency component. Therefore, the Nyquist frequency in this scenario would be 2 * 75 Hz = 150 Hz.

Since we are sampling at the Nyquist frequency, the resulting discrete frequency would be half of the Nyquist frequency, which is 150 Hz / 2 = 75 Hz. Hence, when sampling x(t) at the Nyquist frequency, the resulting discrete frequency would be 75 Hz.

Answer:

Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the

equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find

the equation of a line. I find the equation of a line everytime by following the same three steps:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

Step-by-step explanation:

Given parameters:

Midpoint of AB =  M(3, -1)

Coordinates of A = (5,1)

Unknown:

Coordinates of B = ?

Solution:

To find the mid point of any line, we use the expression below;

              \(x_{m} = \frac{x_{1} + x_{2} }{2}\)    and \(y_{m} = \frac{y_{1} + y_{2} }{2}\)

where \(x_{m}\)  and \(y_{m}\) = coordinates of the mid points = 3 and -1

   x₁  = 5 and y₁ = 1

  x₂ = ?  and y₂ = ?

Now let us input the variables and solve,

            3  = \(\frac{5 + x_{2} }{2}\)           and     -1 = \(\frac{1 + y_{2} }{2}\)

    5 +  x₂  = 6                          -2 = 1  + y₂

            x₂ = 1                             y₂ = -2 -1 = -3

The coordinates of B = 1, -3

Jorge is incorrect since he is estimating the required number of cars using the incorrect methodology. Divide 22 by 4, and the outcome is not 5 with a remnant of 2, but rather 5 with a remainder of 2.

An individual or distinct unit is referred to as "unitary." The goal of this method is to establish values in terms of a single unit as a consequence. The unitary technique, for instance, can be used to calculate how many kilometers a car will travel on one litre of fuel if it currently goes 44 on two.

The following approach can be used to determine how many automobiles are required to carry the remaining passengers:

To determine the necessary number of full cars, divide the number of passengers still on board by each car's capacity: 22 passengers divided by four automobiles results in 5.5 autos.

Find the total required number of cars by rounding up to the next whole number: 6 cars.

Therefore, the answer is six cars will be required by the group to transport the remaining passengers.

Extrapolation is the act of making predictions or estimations about values of the response variable that lie outside the range of the data used in regression analysis. In simpler terms, it is the process of extending a trend line beyond the range of data in order to predict future outcomes.

Extrapolation is considered a bad idea in regression analysis because it is based on the assumption that the linear trend observed in the data will continue indefinitely. However, this assumption may not always be true, and the further away the prediction is from the range of data, the less accurate the prediction is likely to be. In addition, when extrapolating, there is a greater risk of encountering outliers or extreme values that can skew the prediction. This is because the range of data used in the regression analysis may not fully represent the entire population, and therefore, extrapolation may not provide accurate predictions for the population as a whole.

Therefore, it is important to exercise caution when extrapolating and to be aware of the limitations and potential pitfalls associated with this technique. In general, it is recommended to only make predictions within the range of data used in the regression analysis, and to avoid making predictions too far outside this range.
