Jayla= x
keisha= x+ 3
melanie= x + 6
to solve:
42= x + x + 3 + x + 6
42= 3x + 9
-9 -9
33=3x
———-
3
x=11
therefore
jayla is 11
keisha is 14
melanie is 17
Answer: probability distribution is a function of a discrete variable whose integral over any interval is the probability that the random variable specified by it will lie within that interval.
Answer:
3/20
Step-by-step explanation:
This is a division question.
The equation is 3/4 ÷ 5 or, to simplify this, 3/4 ÷ 5/1.
When you divide fractions you have to flip the second number and multiply the two fractions.
So, you have to do 3/4 x 1/5 which is 3/20.
Thus, the answer is 3/20.
Good luck!
