5 0

Answer:

This is because the number '20' is not a perfect square.

Step-by-step explanation:

If you find \sqrt{20}, you will be getting 4.4721935955... which is not a whole number, thus 20 is not a perfect square.

three dice, one red, one blue, and one green, are thrown. what is the probability that the numbers on the three dice are differe
mixer [17]

The odds that the three dice's numbers will be different are 5/9 (probability) when three dice, one each of red, blue, and green, are thrown.

The odds of the green die's number being different from the red die's number are 5/6.

The likelihood that the probability blue die will have a different number from both the red and green dice is 4/6=2/3 in the circumstances where the red and green dice have different numbers.

Consequently,

5/6*2/3

=10/18

=5/9 represents the likelihood that all three numbers are different.

A study found that a factory produces 6 defective computers for every 500 computers that are produced. On the average, what perc
masya89 [10]

Answer:

1.2%

Step-by-step explanation:

We know that for every 500 computers, 6 are defective. So, to know what percentage of computers are defective on average, we can do a rule of three:

500 computers -> 6 defective

100 computers -> X defective

500/100 = 6/X

X = 100 * 6 / 500 = 1.2

So, in average, for every 100 computers, 1.2 are defective, so the percentage is 1.2% (1.2 for every 100)
