Answer: D the final mean is higher than the original

Step-by-step explanation:

90+85+98+60+84+78/6= 82.5 as the original mean

dropping 60 which is the lowest grade means 90+85+98+84+78/5=87 which means the new mean is 87 which is greater than the original mean of 82.5

So the answer is D

How would 5/9 be classified? 1. Rational and real? 2. Whole and integer? 3. Only real? Or 4. Only irrational
Elena-2011 [213]
A rational number is any number that can be written as a ratio or a fraction.

So 5/9 is  a rational number. So basically that eliminates 2, 3, and 4.

And we are left with 1. as our answer choice which is Rational and real.
