Asap tyler has a sister who is three years older than he is and a brother who is two years younger than he is. how old must tyler be in order that the ratio of his sister's age to his brother's age is less than 2.

Answer-

Tyler must be more than 7 years old, so that the ratio of his sister's age to his brother's age is less than 2.

Solution-  

Let's assume that,

Age of Tyler = x years, then

Age of his sister = (x+3) years and Age of his brother = (x-2) years

As given that the ratio of his sister's age to his brother's age must be less than 2, so

Therefore, Tyler's age must be more than 7, in order to satisfy the condition.

the answer to the question is a  

it has the same slope and the same y-intercept.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
