Option B is correct option.

Step-by-step explanation:

We need to solve the inequality: 7 − 9x − (x + 12) less than or equal to 25

$7-9x-(x + 12)\leq 25$

Solving:

$7-9x-(x + 12)\leq 25$

$7-9x-x-12\leq 25$

$-10x-5\leq 25$

Add 5 on both sides:

$-10x\leq 25+5$

$-10x\leq 30$

Divide both sides by -10 and reverse the inequality:

$x\geq -3$

The number line is shown in figure attached.

Option A is correct.

Option B is incorrect because x cannot be less than -3

Option C is correct because −3 less than or equal to x is -3 ≤ can be written as: x≥-3

Option D is correct because when x is greater than or equal to the circle is closed and greater values are on right side of the number line.

So, Option B is correct.

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.
