Solve the absolute value equation: |x|=8

vampirchik [111]

Answer:

x = 8, -8

When taking an absolute value the sign of a number is ignored. Therefore, both 8 and -8 would come out equalling 8.

Answer:

0.614125

Step-by-step explanation:

Given that a manufacturing process with a quality inspection station has on an average 15% of parts are defective.

As soon as one defective part is found, the process is stopped.

We find that number of defectives would be binomial because each part randomly selected has a constant probability of 0.15 being defective

Probability that at least 11 total parts will be inspected before the process is stopped/8 parts have been inspected without finding a defective part

= $P(x\geq 11)/P(x=8)\\$

= Probability of 9th, 10th, 11th should not be defective

= $(1-0.15)^3\\= 0.614125$

Out of 16 spins, a purple-and-red spinner landed on purple 9 times and on red 7 times. Based on experimental probability, how ma

Diano4ka-milaya [45]

Answer:

Option A.

Step-by-step explanation:

It is given that out of 16 spins, a purple-and-red spinner landed on purple 9 times and on red 7 times..

Experimental probabilities are

$P(Purple)=\dfrac{Purple}{Total}=\dfrac{9}{16}$

$P(Red)=\dfrac{Red}{Total}=\dfrac{7}{16}$

Based on experimental probability, we need to find how many of the next 64 spins would we expect on land on red.

The expected number of red in 64 spins is

$\text{Expected red}=64\times P(Red)$

$\text{Expected red}=64\times \dfrac{7}{16}$

$\text{Expected red}=28$

Therefore, the correct option is A.
