Answer:
Incorrect.
Step-by-step explanation:
1 toss could not change the frequency by such a large margin 0.47 ---> 0.55.
The number of heads obtained in 30 tosses = 30 * 0.47 = 14.
So if the next toss came up heads the relative frequency of heads would be
15/31 = 0.48.
For any values less than -3, the answer is undefined, because then you have a negative value for √x+3

I think with the kinds of mixture problems, it's really helpful to make a table.
The equations you actually need are
and
. Since I was so close, I went ahead and just solved it anyway. You can see my setup on the attached image.
