Answer:

The y-intercept in this situation means that when the cab travels 0 miles, the total fee will be $14.00. This indicates that the cab service charges a flat fee of $14.00, regardless of the number of miles traveled.

Step-by-step explanation:

The y-intercept in this situation represents the base fee that the cab service charges regardless of distance traveled. In this case, when the cab travels 0 miles, the total fee is $14.00.

In this context, the y-intercept represents the base fee that the cab service charges, regardless of distance traveled. This is the amount you would pay for a cab ride of 0 miles. From the given table, we can't directly see the y-intercept, but we can infer it using the rate of change or slope, which represents the fee per mile. The amount increases by $1.50 for every additional mile (difference in y divided by difference in x), so to find the y-intercept, we back-calculate from one of the given points, like (2, 17). Subtracting 2 miles' worth of fees from $17 gives a y-intercept of $14. Therefore, when the cab travels 0 miles, the total fee is $14.00, which likely represents a starting charge or a minimum fare.

Step-by-step explanation:

The HCF of the numbers 126, 119 and 196 is 7.

The Highest Common Factor (HCF) of two numbers is the highest possible number that divides both the numbers completely.

The Highest Common Factor (HCF) is also called the Greatest Common Divisor (GCD).

Given are the numbers -

126, 119, 196

We can write the Prime factorization of the numbers given as -

126 = 2 × 3 × 3 × 7

119 = 7 × 17

196 = 2 × 2 × 7 × 7

7 is common in the prime factorization of all the numbers.

Therefore, the HCF of the numbers 126, 119 and 196 is 7.

The linear function that represents the table values is y = 3x + 5.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Using two points from the table, (0,5) and (2,11)

First, we determine the slope m.

Slope m = change in y / change in x

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Plug in the values

Slope m = ( 11 - 5 ) / ( 2 - 0 )

Slope m = 6 / 2

Slope m = 3

Plug the slope m =3 and point (0,5) into the point-slope formula and simplify.

y - y₁ = m( x - x₁ )

y - 5 = 3( x - 0 )

y - 5 = 3x - 0

y - 5 = 3x

Add 5 to both sides

y - 5 + 5 = 3x + 5

y = 3x + 5.

Therefore, the equation of the line is y = 3x + 5.

The correct answer is option A. The empirical rule provides precise statements regarding 1, 2, or 3 standard deviations.

The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution (or approximately normal distribution), about 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. This rule assumes that the mean, median, and mode are equal and the data is symmetrical.

It is a quick and easy way to get a rough estimate of the spread of data in a normal distribution and the proportion of values that fall within certain intervals. However, it should be noted that this is an approximation and not always accurate, especially for distributions that are not close to being normal.

The values of x and y in the parallel lines are 10 and -5 respectively.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, linear angles, alternate interior angles, alternate exterior angles, same side interior angles, vertically opposite angles etc.

Therefore, using same side interior angles,

6x + 2y + 130 = 180

2x - 4y + 140 = 180

Recall same side interior angles are supplementary

Hence,

6x + 2y = 50

2x - 4y  = 40

multiply equation(ii) by 3

6x + 2y = 50

6x - 12y = 120

subtract the equations

14y = - 70

y = -70 / 14

y = -5

Let's find x

6x + 2y = 50

6x = 50 - 2(-5)

6x = 60

This transfer function is a ratio between the gain of the controller (K) and the plant’s open-loop transfer function (G). The denominator is the sum of the gain and the plant’s transfer function, which results in the closed-loop feedback loop.

The closed-loop transfer function from the reference r(s) to the output y(s) for a unity feedback loop is given by:

y(s) = (K*G(s))/(1+K*G(s))

Where K is the gain of the controller, and G(s) is the plant’s open-loop transfer function. This can be derived by examining the block diagram of a unity feedback loop:

The input (r) is fed into a controller (K) whose output is then multiplied by the plant’s open-loop transfer function (G). The sum of the controller output and the plant output is then fed into the summing junction, and the output (y) is the result.

Therefore, the closed-loop transfer function representing the reference r(s) to the output y(s) can be derived as follows:

[tex]y(s) = r(s)*(K*G(s))/(1+K*G(s))\\= (K*G(s))/(1+K*G(s))[/tex]

This can be rearranged to give the final expression:

[tex]y(s) = (K*G(s))/(1+K*G(s))[/tex]

(i) To find the number of students who have taken all three classes, we need to subtract the number of students who have taken only two classes from the number of students who have taken at least one class.

Let's call the number of students who have taken all three classes "x".

The number of students who have taken Calculus and Sociology is 15 + x.

The number of students who have taken Calculus and Spanish is 20 + x.

The number of students who have taken Sociology and Spanish is 13 + x.

Adding these three equations, we have:

15 + 78 + 72 = 15 + x + 78 + x + 72 + x

solving for x

165 = 45 + 3x

120 = 3x

So, x = 40.

hence, 40 students have taken all three classes.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

13. x intercept is the point on a line where the line touches the X axis.

y coordinate will be zero at that point.

x + 6y = 7

y = 0, then x = 7

x intercept = 7

14. 4x + y = 3

y = 0, then 4x = 3 or x = 3/4

x intercept = 3/4

15. y intercept is the point where the line touches the Y axis.

x coordinate will be 0 there.

y - 3x = 4

x = 0, then y = 4

y intercept = 4

16. 2y + x = 8

x = 0, then 2y = 8 or y = 4

y intercept = 4

17. Points given are (2,4) and (1,3).

Slope = (3 - 4) / (1 - 2) = -1 / -1 = 1

A significant positive correlation between two variables means that as one variable increases, the other also increases. This implies that when one variable changes, the other is likely to follow suit. For example, if Variable X increases, Variable Y is likely to increase as well. This can be interpreted as a direct relationship between the two variables. Additionally, a significant positive correlation indicates that the two variables have a strong relationship, meaning that as one variable increases or decreases, the other is likely to follow suit. This can be used to help make predictions and draw conclusions about the relationship between the two variables.
