line of symmetry is the line straight down the middle as if the graph is reflected to the other side

intercepts...

x - intercept is when y = 0, note there is 2 of these a negative and positive root

y - intercept is when x = 0

vertex is the turning point

for an upward curve its a min

for a downward curve it a max

In explaining of the random sampling situation, you tell the jury that Random sampling is a kind of sampling technique where all sample has an equal right or probability to be chosen.

An example of a simple random sample would be the names of 30 employees were chosen out of a box from a company of 300 employees. In this above scenario, the population is all 300 employees, and the sample is random based on the fact that each employee do possess an equal chance of been selected.

By using the example of the argument given above to convince the juror about why the selection is said to be likely to be random.

Answer:

70%

Step-by-step explanation:

To find the percent you put the part (70) out of the whole (100) and then multiply it by 100%. Like this:

[tex]\frac{70}{100} *100[/tex] = 70%

You can also look at it like this, it is already out of 100, so he made 70% of free throws because he made 70 free throws!

Step-by-step explanation:

Here we have to find p(q(x))

q(x) =x -3

we will plug value of q(x) in x of p(x)

p(x) =2x2-4x

p(q(x)) = 2(x-3)2-4(x-3)

= 2(x2-6x+9)-4(x-3)

Answer:

b. {1, 2, 3, 4, 5}

Step-by-step explanation:

Given function:  

c = 25n + 6

(where c is the total purchase cost and n is the number of coins)

Domain:  input values → n-values

If there is a limit of 5 coins per purchase, this means that you can purchase up to and including 5 coins at any one time.  

Therefore, the domain is:  {1, 2, 3, 4, 5}

{1, 2, 3, 4, 5} is a reasonable domain for this function.

So, the correct answer is:

b. {1, 2, 3, 4, 5}.

The cost function for purchasing n coins is given by c = 25n + 6.

However, there is a limit of 5 coins per purchase.

This means that the number of coins (n) should not exceed 5,

as it is not possible to purchase more than 5 coins in a single purchase.

Therefore, a reasonable domain for this function would be the set of numbers from 1 to 5,

since n can take any value between 1 and 5, inclusive.

Hence, {1, 2, 3, 4, 5} is a reasonable domain for this function.

So, the correct answer is:

b. {1, 2, 3, 4, 5}.

Answer:

x^3 + 3x^2 - 10x

Step-by-step explanation:

(x - 0)(x - 2)(x + 5)

= x^3 + 5x^2 - 2x^2 - 10x

= x^3 + 3x^2 - 10x

The value of angle x and y in the triangle XYZ are 53.33 degrees and 106.66 degrees, respectively.

According to the triangle angle sum theorem, the sum of all the angle(interior) of a triangle is equal to the 180 degrees.

The angle XYZ has an angle y which is twice the size of x. Thus,

2x=y

The third angle is 20 degree, which is Z. Thus,

z=20

By the triangle angle sum theorem,

x+y+x=180

x+2x+20=180

3x=180-20

x=160/3

x=53.33

The measure of angle y is,

y=2×53.33

y=106.66

Thus, the value of angle x and y in the triangle XYZ are 53.33 degrees and 106.66 degrees, respectively.

Answer:

V = 508.938 [tex]in^{3}[/tex]

Step-by-step explanation:

The equation to find the volume of a cylinder is:

[tex]V = \pi r^{2} h[/tex]

r = radius

h = height

In the question it gives us the height (2 inches) and the diameter (18 inches).

We need to find the radius from the diameter. To do this, divide the diameter by 2:

r = 18/2 = 9

Now, plug everything into the equation and solve:

[tex]V = \pi (9)^{2} (2)[/tex]

Use a calculator to get the answer:

V = 508.938 [tex]in^{3}[/tex]

(Side note: I don't know what place to round to because in the question it says to "round to the nearest place" but doesn't say tenth, hundred, etc. If the question on your homework says tenth then the answer would be 508.9, hundredth = 508.94, thousandth = 508.938)
