In how many ways can a quality-control engineer select a sample of3 transistors for testing frm a batch of 100 transistors?

Advocard [28]

Answer:

161700 ways.

Step-by-step explanation:

The order in which the transistors are chosen is not important. This means that we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

3 transistors from a set of 100. So

$C_{100,3} = \frac{100!}{3!(100-3)!} = 161700$

So 161700 ways.

What is the midpoint between 0.12 and 0.13

max2010maxim [7]

To find midpoint, you would add the numbers and divide it by the amount of numbers. So it would be 0.12+0.13 divided by 2 because you have 2 numbers. That would equal .25 divided by 2 also known as .125, the final answer.

Help me with this math question please I'm giving away brainliests

Answer:

Step-by-step explanation:

Given function is,

$f(x)=\frac{2x^2+6x}{-4x^2+8x}$

$=\frac{2x(x+3)}{-4x(x-2)}$

This function is not defined at "x(x - 2) = 0"

Therefore, for the values of x = 0 and 2, given function is not defined.

Vertical asymptote → x = 2 [Denominator = 0]

For Horizontal asymptote → $[\frac{2x^2}{-4x^2} =-\frac{1}{2}]$

Therefore, horizontal asymptote → y = $-\frac{1}{2}$

x-intercept,

For f(x) = 0,

Numerator of the function = 0

2x² + 6x = 0

2x(x + 3) = 0

x = -3

Therefore, x - intercept → (-3, 0)

For y-intercept,

x = 0

f(0) = 0

Therefore, graph has no y-intercept.

For holes on the graph,

Since, function is not defined at x = 0,

f(x) = $\frac{(x+3)}{-2(x-2)}$

f(0) = $\frac{(0+3)}{-2(0-2)}$

= $\frac{3}{4}$

Therefore, hole on the graph → $(0, \frac{3}{4})$
