Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) to be 3. Which best describes his error?

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
