Answer:

"His mistake was on line 1. He didn't distribute the negative sign (indicating a -1) to everything in the equation for y."

The correct solution is: x = -10, y = -38

Step-by-step explanation:

2x - y = 18

y = 4x + 2

Substitute the given value for y into the first equation:

2x - (4x + 2) = 18

2x - 4x - 2 = 18 ** here, he didn't distribute the (-) to everything in the parentheses that represents y

-2x -2 = 18

add 2 to both sides

-2x = 20

divide by -2

x = -10

-------------------

solve for y

y = 4x + 2

y = 4(-10) + 2

y = -40 + 2

y = -38

------------------

Check the math:

2x -  y = 18

2(-10) - (-38) = - 20 + 38 = 18

In order to calculate the area of the board that can be seen, we need to calculate the area of the the rectangular board and the circular frame. The difference of both's area is the required answer.

Refer to the attachment for step by step solution. :)

The area of the board that can be seen is  11.44 decimeter square.

The area of the board that can be seen is equivalent to the difference between the area of the circular picture and the area of the rectangular board.

Area of a circle = πr²

Where :

3.14 x 2² = 12.56 d²

Area of the rectangle = length x width

6 x 4 = 24

Area of the board that can be seen = 24 - 12.56 = 11.44 decimeter square

C. 360 Square meters

........

The total area is 360 square meter.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Given:

We get Three Rectangle

First Rectangle:

length = 12 m

width = 16 m

So, Area = 12 x 16 = 192 square meter.

Second Rectangle:

length = 8 m

width = 12 m

So, Area = 8 x 12 = 96 square meter.

Third Rectangle:

length = 12 m

width = 6 m

So, Area = 12 x 6 = 72 square meter.

Thus, the total area = 192 + 96+ 72 = 360 square meter.

Answer:

By the Central Limit Theorem, an approximately normal distribution, with mean $6425 and standard deviation $344.35.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Sample mean was $6,425 with a standard deviation of $3,156

This means that [tex]\mu = 6425, \sigma = 3156[/tex]

Sample of 84:

This means that [tex]n = 84, s = \frac{3156}{\sqrt{84}} = 344.35[/tex]

Answer:

4,670.61 Dollars

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.5/100

r = 0.025 rate per year,

Then solve the equation for A

A = Pert

A = 2,500.00(2.71828)(0.025)(25)

A = $4,670.61

Answer:

23ft longer

Step-by-step explanation:

The shorter piece is 15 feet, while the longer piece is 25 feet

Let the longer piece be y, and the shorter piece be x.

So, we have:

[tex]x + y = 40[/tex] --- the length of the rope

[tex]y =2x - 5[/tex] --- the relationship between the short and the long piece

Substitute 2x - 5 for y in [tex]x + y = 40[/tex]

[tex]x + 2x - 5 =40[/tex]

[tex]3x - 5 =40[/tex]

Add 5 to both sides

[tex]3x =45[/tex]

Divide both sides by 3

[tex]x =15[/tex]

Substitute 15 for x in [tex]y =2x - 5[/tex]

[tex]y =2 \times 15 -5[/tex]

[tex]y =30 -5[/tex]

[tex]y =25[/tex]

Hence, the shorter piece is 15 feet, while the longer piece is 25 feet

The surface area of the prism will be equal to 366 square meters.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.

Given that:-

The surface area of the prism will be calculated as:-

Surface area = Sum of the area of all sides

There are three rectangle faces and two triangular faces in the triangular prism.

Surface area = 3 ( area of rectangle) + 2 (area of triangle)

Suraface area= 3 ( 10 x 9 ) + 2 [( 1/2)(16 x 6)]

Surface area = 270 + 96 = 366 square meter.

Therefore the surface area of the prism will be equal to 366 square meters.
