Answer

x = 12, y = 5

x = -13, y = -20

Step by step explanation:

You have two equations, and you have to find a way to merge them.

x - y = 7 —— {1}

From {1}, y = x - 7 —— {2}

x² + y = 149 —— {3}

Rep {2} in {3}

x² + y = 149

x² + (x-7) = 149

x² + x - 156 = 0

(x-12) (x+13) = 0

x = 12 and x = - 13

When x = 12, y = 12 - 7 = 5

(12, 5)

When x = - 13, y = - 13 - 7 = - 20

The slope of the line that represents this relationship is 72.

Let the service fee charged by the electrician be represented by "s" and the hourly charge be represented by "h".

s + 3h = 301 (for the job that takes 3 hours)

s + 6h = 517 (for the job that takes 6 hours)

We can solve this system of equations using elimination or substitution to find the values of "s" and "h". For simplicity, we'll use the substitution method.

From the first equation, we can solve for "s" in terms of "h":

s = 301 - 3h

Substituting this into the second equation:

(301 - 3h) + 6h = 517

Simplifying:

301 + 3h = 517

3h = 216

h = 72

Substitute the provided value of h = 72 first equation:

s + 3(72) = 301

Simplifying:

s = 85

So the electrician charges a service fee of $85 and an hourly rate of $72.

The slope of the line that represents this relationship can be interpreted as the rate of change in cost per hour of work. This is simply the hourly charge, which is $72 in this case.

Therefore, the slope of the line is described as,

slope = $72/hour

Answer: Let's denote the masses of the four men as a, b, c, and d. Then we can use the given information to set up a system of equations:

Mean mass of 4 men is 97.5kg:

(a + b + c + d) / 4 = 97.5

a + b + c + d = 390

Modal mass is 101kg:

We know that one of the men has a mass of 101kg. Let's say that man is a. Then we have two cases:

Case 1: b, c, and d each have a mass less than 101kg.

In this case, the second largest mass must be the mode. Let's say that mass is b. Then we have:

b = a - x (where x is some positive number less than 4)

c = a - y (where y is some positive number less than 4 and not equal to x)

d = a - z (where z is some positive number less than 4 and not equal to x or y)

Note that we subtract x, y, and z from a because b, c, and d have masses less than a.

Then we have:

a + (a - x) + (a - y) + (a - z) = 390

4a - (x + y + z) = 390

Case 2: b, c, and d each have a mass greater than 101kg.

In this case, the second smallest mass must be the mode. Let's say that mass is b. Then we have:

b = a + x (where x is some positive number less than 4)

c = a + y (where y is some positive number less than 4 and not equal to x)

d = a + z (where z is some positive number less than 4 and not equal to x or y)

Note that we add x, y, and z to a because b, c, and d have masses greater than a.

Then we have:

a + (a + x) + (a + y) + (a + z) = 390

4a + (x + y + z) = 390

Range is 8kg:

The range is the difference between the largest and smallest masses. Let's say that the smallest mass is e and the largest mass is f. Then we have:

f - e = 8

Now we have three equations (either from Case 1 or Case 2) and three unknowns (a, x, and y or a, x, and z) that we can solve for to find the masses of the four men. However, the system of equations is quite complicated and solving it by hand can be tedious. One way to solve it is to use a numerical method, such as Newton's method or the bisection method. Alternatively, we can use a computer algebra system to solve it.

the probability of the event is 20/216 = 5/54.To calculate , we need to find the total number of outcomes where this event occurs and divide it by the total number of possible outcomes.

The total number of possible outcomes when rolling three 6-sided dice is 6 x 6 x 6 = 216.

To count the number of outcomes where the number on the first die is strictly larger than the sum of the numbers on the other 2, we can use the following steps:

- Since the first die has to be strictly larger than the sum of the other 2, the maximum number that can appear on the other 2 dice is 5+5=10.
- Therefore, for each number from 2 to 6 that appears on the first die, we count the number of ways to get a sum less than or equal to 10 on the other 2 dice.
- Using a table or combinatorial reasoning, we can count the total number of such outcomes as 10+6+3+1+0 = 20.

COVARIANCE.S uses the number of data points minus one to adjust for the sample size. The functions COVARIANCE.P and COVARIANCE.S return different values when using the same data.

The reason why COVARIANCE.P and COVARIANCE.S return different values when using the same data is that they use different formulas to calculate covariance. COVARIANCE.P calculates the average of the product of deviations from the means of the two variables, while COVARIANCE.S calculates the sum of the product of deviations from the means of the two variables, divided by the number of data pairs minus one.

COVARIANCE.P assumes that the data represents the entire population, and therefore divides by the total number of data points. COVARIANCE.S, on the other hand, assumes that the data represents a sample of the population, and therefore divides by the number of data points minus one to account for the degree of freedom.

In summary, the difference between COVARIANCE.P and COVARIANCE.S lies in the way they account for the variance in the data, with COVARIANCE.P using the total number of data points, while COVARIANCE.S uses the number of data points minus one to adjust for the sample size.

Graphing a vector in three dimensions can be challenging, but we can use the following method:
Start at the origin (0, 0, 0) of the 3D coordinate system.
Move 3 units in the x-direction, 3 units in the y-direction, and 9 units in the z-direction.

The equation of the given line is y = 3 - 5x.

To compute the least squares error for the given line, we need to find the vertical distance between each point and the line, square them, and add them up.

Let's first find the predicted y-values for each given x-value using the equation of the line:

For x = -5, y = 3 - 5(-5) = 28

For x = 0, y = 3 - 5(0) = 3

For x = 5, y = 3 - 5(5) = -22

For x = 10, y = 3 - 5(10) = -47

Now we can find the vertical distance between each point and the line:

For the point (-5, 4), the vertical distance is 4 - 28 = -24

For the point (0, 4), the vertical distance is 4 - 3 = 1

For the point (5, 3), the vertical distance is 3 - (-22) = 25

For the point (10, 1), the vertical distance is 1 - (-47) = 48

To prove that the statement is true for all positive integers n, we will use mathematical induction.

Base case: When n = 1, there is only one dot in the triangle, and the total number of dots is 1, which is equal to n( n + 1)/2 = 1(1+1)/2 = 1. Therefore, the statement is true for n = 1.

Inductive step: Assume that the statement is true for some positive integer k, which means that the kth triangular number can be represented by the formula k(k+1)/2. We need to show that the statement is also true for k + 1, which means that (k+1)((k+1)+1)/2 = (k+1)(k+2)/2 dots can be represented in a triangle with k + 1 dots in its base.

To show this, we can construct a triangle with k + 1 dots in its base by adding one more row to the kth triangle. This row will have k + 1 dots, and the total number of dots in the triangle will be (k+1) + k(k+1)/2 = (k+1)(k+2)/2, which is the formula for the (k+1)th triangular number.

To solve this problem, we can use trigonometry and set up a right triangle with the observer's eye, the top of the building, and the ground. The distance between the observer and the building forms the adjacent side of the triangle, and the height of the building forms the opposite side. We can use the tangent function to solve for the height of the building:

tan(17 degrees) = opposite/adjacent

First, we need to convert the distance from the observer to the building from meters to centimeters, since the height of the observer's eye is given in centimeters.

47 meters = 4700 centimeters

Next, we can plug in the values we have and solve for the height of the building:

To prove the inequality 2^n > n^2 using induction with a basis greater than 4, we will use n=5 as the basis.

Basis: n = 5
2^5 = 32 and 5^2 = 25. Since 32 > 25, the inequality holds true for n = 5.

Now, we need to assume that the inequality holds true for an arbitrary positive integer k > 4, and then prove that it holds true for k + 1.

Assume: 2^k > k^2 for k > 4.

Prove: 2^(k + 1) > (k + 1)^2

Step 1: Multiply both sides of the assumption by 2.
2 * (2^k) > 2 * (k^2)

Step 2: Simplify the left side of the inequality.
2^(k + 1) > 2k^2

Step 3: Show that 2k^2 is greater than (k + 1)^2 for k > 4.

Answer: To differentiate this function, we need to use the product rule and the chain rule.

First, we will simplify the function:

f(y) = (1/y^2 - 3/y^4) * y(y + 9y^3)

f(y) = (y + 9y^3) / y^3 - (3y + 27y^3) / y^5

f(y) = y^-3 * (y^4 + 9y^6 - 3y^4 - 27y^6)

f(y) = 6y^4 / y^3

f(y) = 6y

Now we can differentiate:

f'(y) = 6

Therefore, the derivative of f(y) is 6.

Using product rule and power rule of differentiation, the derivative of the function f(y) = 1/y² - 3/y⁴ * (y + 9y³) is f'(y) = 12/y⁷ - 6/y⁶ - 54/y⁵.

To differentiate the given function,

We need to use product rule and the power rule of differentiation

use product rule to differentiate two terms in the function;

Let's consider the first term: 1/y²

The derivative of 1/y² with respect to y is:

d(1/y²)/dy = -2/y³

Now, let's consider the second term: -3/y⁴ * (y + 9y³)

The derivative of -3/y⁴ with respect to y is:

d(-3/y⁴)/dy = 12/y⁵

The derivative of (y + 9y³) with respect to y is:

d(y + 9y³)/dy = 1 + 27y²

Let's use product rule to differentiate the expression

Using the product rule, the derivative of the entire expression f(y) = 1/y₂- 3/y⁴ * (y + 9y³) is:

f'(y) = (1/y²) * (d(-3/y⁴ * (y + 9y³))/dy) + (-3/y⁴ * (y + 9y³)) * (d(1/y²)/dy)

Let's plug the value into the previous expression

f'(y) = (1/y²) * (12/y⁵) + (-3/y⁴* (y + 9y³)) * (-2/y³)

Simplifying further:

f'(y) = 12/y⁷ - 6(y + 9y³)/y⁷
