SA school has 900 concert tickets for sale. Some of them are for reserved seats (x) and the
rest are for general admission (y). No more than 600 reserved seat tickets can be sold. They
know they will sell at least 200 general admission tickets. Write a system of inequalities that
shows how many of each type of ticket can be sold and then graph the feasible region.

Using the uniform distribution, there is a 0.6667 = 66.67% probability that it takes a randomly selected customer more than 30 seconds to connect to the internet.

It is a distribution with two bounds, given by a and b, in which each possible outcome is equally as likely.

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

For this problem, the connection time has parameters a = 20 sec and b = 50 sec, as stated in the problem.

The probability that it takes a randomly selected customer more than 30 seconds to connect to is P(X > 30).

Hence, applying the formula, with the bounds, we have that:

P(X > 30) = (50 - 30)/(50 - 20) = 2/3 = 0.6667.

The measure above is the desired probability.

In linear equation 109333.2 dollars is the average yearly salary of an individual with each of these final degrees .

What is a linear equation ?

let x be the salary of individual with bachelor degree

Then the average salary of individual with Masters degree is:

(2x-40000)

the combined of two salaries is 130000:

x+(2x-40000)=130000

3x-40000=130000

3x=130000+40000

x=170000/3

x = 56,666.66

x= 56,666.6  dollars ( the average salary of bachelor degree)

the average salary of Masters degree = 2x - 40000

2(56666.6)-40000 = 109333.2 dollars

The solution for the equation 7x-4 = -18 is x = -2

The equation given is, 7x - 4 = -18.

We will try to solve this equation using elimination method in the following steps.

7x-4= -18

⇒ 7x-4+4 = -18+4

⇒7x = -14

⇒7x/7 = -14/7

⇒x = -2 is the solution for the given equation.

In the first step, we added 4 on both sides to eliminate -4 on the left side.

In the next step, we divided the both sides by 7 to eliminate the 7 on the left side. Finally, we got the solution as x = -2.

Angle W

Here we have Opposite Angles by Vertex, so

W = 14

According to the attached figure, the angle W is also corresponding, so in the triangle CEG one of the angles will be 14°

Angle Z

The sum of the interior angles of a triangle is 180°, so for triangle CEG:

Z + W + 78 = 180

Z + 14 + 78 = 180

Z = 88

Angle X

Z and 4X are complementary angles, then

Z + 4X = 180

Answer:

  (x, y, z) = (-62, 50, -9)

Step-by-step explanation:

You want the solution to this system of equations using the inverse of the coefficient matrix.

  x+2y+3z = 11

  2x+3y+4z = -10

  −x−4y−8z = −66

The inverse of the coefficient matrix is the transpose of the cofactor matrix, divided by the determinant. There are some shortcuts that can be used to make the computation easier. Easiest is letting a calculator find the matrix inverse. (See the first attachment.)

The solution to the set of equations is the product of the inverse matrix and the constant vector on the right of the equal signs. That, too, can be found using a calculator. (See the second attachment.)

The solution is (x, y, z) = (-62, 50, -9).

The value of (f - g)(x) = 4x² - x - 4.

Function - A function is a relationship or expression involving one or more variables.  It has a set of input and outputs.  Each input has only one output.  The function is the description of how the inputs relate to the output.

We have been given that -

f(x) = 4x² - 3

g(x) = x + 1

Find out  (f - g)(x) = ?

(f - g)(x) = 4x² - 3 - (x + 1)

(f - g)(x) = 4x² - 3 - x - 1

Output of

The area formula for the triangle is 1/2 b•h

1/2 divided by 5 is 2.5

2.5 x 10 is 25.

Step-by-step explanation:

Yes, it is possible to use absolute value when subtracting two negatives and as such it does not only work when one number is negative.

When adding two negative numbers, add the absolute value of the numbers and keep the negative sign.

For example -1 + -2 = - (||-1| + |-2||), which is -(1 + 2) or -3

The absolute value when subtracting two negatives is -2¹/₂ - (-1²/₃) is possible because when subtracting, we will change the subtraction to addition and change the sign of the number being taken away.

Thus, we can conclude that it is possible to use absolute value when subtracting two negatives.
