Answer:

3/4

Step-by-step explanation:

make 1/2 and 1/4 have common denominators (4) so 2/4(aka 1/2) + 1/4 is 3/4

To perform a certain type of blood analysis, lab technicians must perform two procedures. The first procedure requires either on

andrew-mc [135]

The random numbers can take any value randomly.

A simple random sample is selected in such a manner that each unit has the equal probability of being included in the sample.

The possible outcomes of the given experiment are

(1, 1) ,(1, 2) , (1, 3) , (2, 1) , (2, 2) , (2, 3)

The first procedure requires either one or two separate steps.

This means it cannot take the third step in the first procedure.

Let 1 take the first and the second step.

So if 1 occurs then 1,2, can occur and 3 cannot occur.

Similarly

If 2 occurs then 1,2, and 3 can occur.

The second procedure requires either one, two, or three steps.

Therefore

Experimental Outcomes Value of x

(3, 3) 0 Not possible

Describe the graph of y=1/2x-10 -3 comapred to the graph of y= 1/x

saw5 [17]

The parent function is:

$$y=\frac{1}{x}$

The transformed function is:

$$y=\frac{1}{2 x-10}-3$

$$y=\frac{1}{2(x-5)}-3$

$$y=\frac{1}{2}\left(\frac{1}{x-5}\right)-3$

Comparison of simplified transformed function with the parent function:

The function multiplying by a number indicates dilation.
The function is being compressed in vertical direction by a factor of 2 if the number lies between 0 and 1.
Subtracting a number from x indicates a horizontal shift towards right.
That is the parent function is transformed 5 units to right.
Subtracting a number from the function indicates a downward shift.
That is the parent function is transformed 3 units down.

Hence the graph of $y=\frac{1}{2 x-10}-3$ is the graph of $y=\frac{1}{x}$ stretched vertically, shifted right by 10 unit and shifted 3 unit down.

The image of the graph is attached below.

If you are good at sequences in math please help I am giving more points

Lunna [17]

Answer:

Graphs C and D show an arithmetic sequence.

Step-by-step explanation:

Arithmetic sequences have a common difference, meaning that the gap between each term in the sequence is always the same.

In Graphs A and B, the gap between terms seems to be changing. That tells us that they aren't arithmetic. Instead, those are geometric sequences.

Meanwhile, Graphs C and D appear to be straight, meaning that the gap between the terms is constant.

What is the intermediate step in the form (x+a)2 = b as a result of completing the square for the following

skelet666 [1.2K]

For this case we have the following expression:

$x ^ 2-4x + 10 = 4x + 10$

We follow the steps below:

We subtract 4x on both sides of the equation:

$x ^ 2-4x + 10-4x = 4x + 10-4x\\x ^ 2-8x + 10 = 10$

We subtract 10 from both sides of the equation:

$x ^ 2-8x + 10-10 = 10-10\\x ^ 2-8x = 0$

Now, we must complete squares.

When we have an equation of the form:

$ax ^ 2 + bx + c = 0$ , if we want to complete squares we must subtract c on both sides of the equation obtaining:

$ax ^ 2 + bx + c-c = -c\\ax ^ 2 + bx = -c$

The square is completed by adding to both sides of the equation: $(\frac{b}{2})^{2}$

So, we have left:

$ax^2+bx + (\frac {b} {2})^{2} = - c + (\frac {b} {2}) ^ {2}$

In the given expression we have:

$a = 1\\b = -8\\c = 0$

And to complete the square we have:

$(\frac {b} {2}) ^ {2} = (\frac {-8} {2}) ^ {2} = 16$

Rewriting we have:

$x ^ 2-8x + 16 = 16$

We factor the left side of the equation, that is, we look for two numbers that when added together result in -8 and when multiplied as a result 16. We have:

$-4-4 = -8\\-4 * -4 = 16$

So, we have:

$(x-4) (x-4) = 16\\(x-4) ^ 2 = 16$

Answer:

The intermediate step is to complete squares

$(x-4) ^ 2 = 16$
