Which of the following is a random sample?

Answer:

an interior angle is an angle inside a shape, while an exterior angle is an angle made by the side of a shape and a line drawn out from an adjacent side. The sum of the interior angles of a triangle is always 180. ... An exterior angle is equal to the sum of the non-adjacent interior angles.

The points that verify the system of inequalities are:

point E, pointF, and point G.

Step-by-step explanation:

Please see the attached image that illustrates the boundary lines in your system of inequalities.

The boundary line for the inequality [tex]2x+y<10[/tex] is depicted in green, while the boundary line for the inequality [tex]2x-4y>8[/tex] is depicted in red.

By solving for y in each inequality, we understand which half-plane should be considered for the inequality:

First inequality (green boundary line) :

[tex]2x+y<10\\y=10-2x[/tex]

This means that we are to consider the points below the green boundary line.

Second inequality (red boundary line) :

[tex]2x-4y >8\\2x-8>4y\\y<\frac{1}{2} x-2[/tex]

This means we have to consider the points below the red boundary line.

Recall as well that both conditions we arrived at have to be satisfied by the points that are solutions of both inequalities.

From the image, we can see that there are only three points that reside at the same time below the green and the red boundary lines. These points are: point E, pointF, and point G.

On the other hand, we have two points that lie on a boundary line (point J and H), but they should be ignored, since the system of inequalities contain just inequality symbols < or >, and not the "equal" sign.

Answer:

x=1

Step-by-step explanation:

First, you shift the -2 to the other side. Your new equation is 2^2x -2^x=2. Then, you continue to solve and simplify the equation. Your final answer will be x=1.

Answer: f(n) = 4n + 97 (or 97 + 4n)

Step-by-step explanation:

Distribute 4 and (n-1)

f(n) = 93 + 4n - 4

Add 93 and 4

f(n) = 97 + 4n

Answer:

The answer is 93 & 4

Step-by-step explanation:

Answer: She earned 868,5 in total last week.

Step-by-step explanation:

18 x 40 = 720 --> earned during the first 40 hours of work

27 x 5,5 = 148,5

148,5 + 720 = 868,5--> total

Answer:

$868.50

Step-by-step explanation:

She worked for 40 hours and gained $18 per hour. That equals $720. She then worked for 5.5 more hours gaining $27 an hour. That equals $148.5. Add those together and you get $148.50.

Answer:

42

Step-by-step explanation:

During the season, 40% of the goals are scored the by the star player.  This means that 60% of the goals are scored by everyone else.

100% - 40% = 60%

To find how many goals are scored by the rest of the team, convert the percentage to a decimal.  You then have to multiply the decimal by the total goals scored.

60% = 0.6

70 × 0.6 = 42

The rest of the team scored 42 goals.  

Answer:

42

Step-by-step explanation:

40% of 70=28

70-28=42

________________________________

Solution,

X+7=23

or,X=23-7

X=16

The value of X is 16.

Hope it helps

Good luck on your assignment

______________________________

Answer:

Step-by-step explanation:

x  + 7 = 23

When doing this problem, the general goal is to make one side only have 'x'. To do that, subtract from one side the amount that you subtract from the other side.

x + 7 = 23

   - 7 = -7     <-- This is where you remove from one side what you remove          x + 0 = 16           from the other side.

Now that one side only has X, we can find the answer.

x = 16

Answer:

5x⁵4x³+2x²+5x+3

Polynomials will be closed under an operation if the operation produces another polynomial. (2x2 + 3x + 4) + (x2 - 5x - 3) = 3x2 - 2x + 1

Step-by-step explanation:

Answer:

x=-3

Step-by-step explanation:

2^4x = 8^x-3

writing 8 as 2^3

2^4x = 2^3^x-3

We know a^b^c = a^(b*c)

2^4x = 2^(2*(x-3))

2^4x = 2^(2x-6)

The bases are the same so the exponents are the same

4x = 2x-6

Subtract 2x from each side

4x-2x= 2x-6-2x

2x=- 6

Divide by 2

2x/2 = -6/2

x = -3

Answer:

The following graph represents the function g(x)=|x+4| +2

1) On a coordinate plane, an absolute value graph has a vertex at (-4,2)

Step-by-step explanation:

A vertex can bed defined as a point where two lines meet. In a graph, a vertex can also be interpreted as the point where the direction of the line or curve change

The function is given by:

[tex]g(x)=|x+4|+2[/tex]

which is an absolute value function. We need to find the vertex of the graph.

The graph drawn is attached below.

We can see in the graph that at x = -4 and y = 2 , a point is formed where the straight line changes its direction.

So the vertex is formed at (-4,2)

Answer:

A. (-4,2)

Step-by-step explanation:

Answer:

0.25 seconds

Step-by-step explanation:

First let's expand the function h:

[tex]h = -16(t- 1/4)^2 + 49[/tex]

[tex]h = -16(t^2 - t/2 + 1/16) + 49[/tex]

[tex]h = -16t^2 + 8t - 1 + 49[/tex]

[tex]h = -16t^2 + 8t + 48[/tex]

To find when the marshmallow reaches the maximum height, we can use the formula to find the vertex of the quadratic function, and the x-coordinate of the vertex is when we have the maximum height:

[tex]x_{vertex} = -b/2a[/tex]

In our equation, b = 8 and a = -16, so:

[tex]t_{vertex} = -8 / (-32) = 0.25\ seconds[/tex]

Answer: 30 dominoes in total.

Step-by-step explanation:

Each line is 21 inches long.

the space between dominoes is 1 + 1/2 inches.

(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,

The we have N + 1 dominoes per line, and the distance is:

N*(1 + 1/2)inches = 21 inches

If we find N, we can find the number of domineoes in each line:

N = 21/(1 + 1/2) = 14

This means that we have 14  + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.

Answer:

2

Step-by-step explanation:

First we have to figure out which order to solve this equation.

Following the rules of PEMDAS, we know it would be 5 - [6 x 8 ( ÷ 8 ) ] + 3.

Please tell me if you need a larger explanation on PEMDAS, or what the brackets and parenthesis mean.

Next we simplify the equation, bringing us to the answer, 2.

Once again, please tell me if you need to know how I simplified the equation.

Hope this helped :)

Answer:

Associate the numbers or coordinates with something in your life. Think of it from every possible aspect. For example, number 7. I just think of it as "7 is half of 14, there are 7 days in a week, 7 can be said as 70, which means 7 tea cups. See like that, now when you try and remember the numbers, you are able to pick up on these trail of thoughts are trace it back to its origin, which here is 7.

Answer:

Multiplying the vertex matrix with the matrix gives us a reflection matrix. The most common matrix reflections are seen as a reflection in the x-axis as well as reflection in the y-axis. It can also be reflected by  90 degrees or by 180 degrees. So, one way to remember the elements is by multiplying the given matrix by a unit matrix. And on the other hand, you can remember the elements remembering by what degree we are reflecting the matrix. This way makes it easier to remember the elements.
