Answer: The point (-2, 4) is on the circle (x - 5)^2 + (y + 3)^2 = 25.

Step-by-step explanation: The point (-2, 4) is on the circle (x - 5)^2 + (y + 3)^2 = 25. To check if a point is on the circle, we can substitute the point's x and y coordinates into the equation of the circle. If the equation is true, then the point is on the circle. In this case, substituting (-2, 4) into the equation of the circle.

Step-by-step explanation:

A function's behaviour as x approaches positive or negative infinity might reveal vertical, horizontal, and oblique asymptotes. As x approaches a value, vertical asymptotes occur. As x approaches infinity, horizontal asymptotes occur. As x approaches infinity, oblique asymptotes occur.

To identify vertical asymptotes, we examine the behavior of the function as x approaches a particular value. For example, let's consider the function f(x) = 1 / (x - 2). As x approaches 2, the denominator becomes very close to zero, causing the function to approach infinity or negative infinity. Hence, x = 2 is a vertical asymptote.

Horizontal asymptotes are determined by analyzing the behavior of the function as x approaches positive or negative infinity. For instance, let's take the function f(x) = (3x^2 + 2x - 1) / (2x^2 + x + 1). As x approaches infinity or negative infinity, the highest power terms dominate the function. In this case, both the numerator and denominator have the same highest power term (x^2), so the ratio of the coefficients determines the horizontal asymptote. Therefore, the horizontal asymptote for this function is y = 3/2.

Oblique asymptotes occur when the function approaches a non-horizontal line as x approaches positive or negative infinity. Consider the function f(x) = (3x^2 + 2x + 1) / (x + 1). By performing polynomial long division or synthetic division, we can see that the quotient is 3x + 1. As x approaches infinity or negative infinity, the function approaches the line y = 3x + 1. Hence, y = 3x + 1 is an oblique asymptote for this function.

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Answer: the mean of the data set is 4.8, and the standard deviation is about 1.94. The answer is C.

Step-by-step explanation:

To find the mean and the standard deviation of the data set {2, 3, 6, 7, 6}, we can use the following formulas:

Mean = (sum of all data values) / (number of data values)

Standard deviation = sqrt[(sum of squared differences from the mean) / (number of data values)]

First, we need to find the mean:

Mean = (2 + 3 + 6 + 7 + 6) / 5

Mean = 4.8

Next, we can find the standard deviation:

Calculate the differences between each data value and the mean:

2 - 4.8 = -2.8

3 - 4.8 = -1.8

6 - 4.8 = 1.2

7 - 4.8 = 2.2

6 - 4.8 = 1.2

Square each difference:

(-2.8)^2 = 7.84

(-1.8)^2 = 3.24

(1.2)^2 = 1.44

(2.2)^2 = 4.84

(1.2)^2 = 1.44

Find the sum of the squared differences:

7.84 + 3.24 + 1.44 + 4.84 + 1.44 = 18.80

Divide the sum by the number of data values:

18.80 / 5 = 3.76

Take the square root:

sqrt(3.76) = 1.94 (rounded to two decimal places)

Therefore, the mean of the data set is 4.8, and the standard deviation is about 1.94. The answer is C.

Dominic receives 12 pounds on an item whose usual price is 80 pounds

The given parameters are:

Discount =15%

Price = p

Amount of discount = d

The equation that represents the amount of discount offered (d) on an item whose usual price is p is

d = Discount * p

This gives

d = 15% * p

Evaluate

d = 0.15p

In (a), we have

d = 0.15p

Here, p = 80

So, we have

d = 0.15 * 80

Evaluate

d = 12

Answer:

21 is your answer

Step-by-step explanation:

The combination formula is used to calculate the number of ways to choose r items from a set of n items without regard to order. The formula is:

C(n,r) = n! / (r! * (n-r)!)

where n is the total number of items and r is the number of items to be chosen.

Using this formula, we can solve the problem when n = 7 and r = 5 as follows:

C(7,5) = 7! / (5! * (7-5)!)

= (7 x 6 x 5 x 4 x 3 x 2 x 1) / [(5 x 4 x 3 x 2 x 1) x (2 x 1)]

= (7 x 6) / (2 x 1)

= 21

Therefore, there are 21 ways to choose 5 items from a set of 7 items without regard to order.

The average time in hours from when a machine breaks until it is fixed is approximately 11.3 hours.

Given,

Benny's arcade has five video game machines

The average time between failures = 34 hours

The maintenance engineer can repair a machine in about = 13 hours

The failure time and repair times are both exponentially distributed

The formula for the mean of an exponential distribution is mean = 1/λ where λ is the rate parameter of the distribution.

In this problem, the rate parameter of both the failure time and repair time is the reciprocal of their respective averages. Therefore,

λ_f = 1/34λ_r = 1/13

Now, let's find the average time from when a machine breaks until it is fixed using the fact that the sum of two independent exponential distributions with rate parameters λ1 and λ2 is itself an exponential distribution with rate parameter λ1+λ2.

So, the rate parameter for the time from when a machine breaks until it is fixed is λ_f+λ_r = 1/34+1/13

= 0.0885 hours⁻¹ (approximately)

Hence, the average time from when a machine breaks until it is fixed is mean = 1/λ= 1/0.0885 ≈ 11.3 hours (approximately).

Therefore, the average time in hours from when a machine breaks until it is fixed is approximately 11.3 hours.

The area A of the rectangle as a function of the length, L of one of its sides is A = 8L - L²

The perimeter of a rectangle is P = 2(L + W) where

Given that P = 16 m,

P = 2(L + W)

16 = 2(L + W)

16/2 = L + W

L + W = 8

So, W = 8 - L

The area of the rectangle, A = LW where

Since W = 8 - L, substituting W into the equation for A, we have

A = LW

A = L(8 - L)

A = 8L - L²

The covariance and the correlation coefficient between two variables should always have the same sign is False.

The covariance and the correlation coefficient between two variables can have different signs. The covariance is a measure of the direction and strength of the linear relationship between two variables. It can be positive, indicating a positive relationship where both variables move in the same direction, or negative, indicating an inverse relationship where the variables move in opposite directions.

On the other hand, the correlation coefficient is a standardized measure of the linear relationship between two variables, ranging from -1 to 1. It can also be positive or negative, depending on the direction of the relationship, but its magnitude is always between 0 and 1, indicating the strength of the relationship.

A variable in mathematics is a representation of any quantity whose value is changeable.

For example speed of a vehicle is a variable.

The value of the variable changes but the meaning of the variable never for example speed of vehicle changes but the word speed does not change.

A discrete variable is a variable whose values are different.

Since car color is not a variable because the meaning of variable is not constant in car color.

y = mx + b.

m is the slope or rate of change and b is the y-intercept.

In an exponential function: y = a(b)ˣ,

a is the initial value and r is the rate of change.
