It is true because a rational function is defined as those functions where the variable is placed in the denominator, which must be restricted, because all denominators cannot be equal to zero, other wise it would be undetermined

1. In a table of random digits, Each digit is to occur with a probability of 0.1

anyanavicka [17]

(A) Just because every digit has an equal chance of appearing does not mean that all will be equally represented. (See "gambler's fallacy")

(B) The experimental procedure isn't exactly clear, so assuming a table of digits refers to a table of just one-digit numbers, each with 0.1 chance of appearing (which means you can think of the digits 0-9), you should expect any given digit to appear about 0.1 or 10% of the time.

So if a table consists of 1000 digits, one could expect 7 to appear in 10% of the table, or about 100 times.

Leila says that 75% of a number will always be greater than 50% of any other number. Complete one inequality to support Leilas c

Greeley [361]

If a number is positive, Leila's theory that 75% of a number will always be greater than 50% of another number is true; however, if both numbers are negative, or if the number of which she finds 50% is much greater than the number of which she finds 75%, Leila's theory could be incorrect.

This inequality shows that Leila is correct: $100(0.75) \geq 50(0.50)$ (which simplifies to $75 \geq 25$ )

This inequality shows that Leila is incorrect: $50(0.75) \geq 100(0.50)$ (which simplifies to $37.5 \geq 50$ )

Hope this helps!
