Answer:

And we can find this probability with the complement rule:

Step-by-step explanation:
For this case we define the random variable X ="driving distance for the top 100 golfers on the PGA tour" and we know that:

And for this case the probability density function is given by:

And the cumulative distribution function is given by:

And we want to find this probability:

And we can find this probability with the complement rule:

This is how the first one would be done. sorry if it’s a little messy the answer is 9. but try using photomath for the rest. it gives you the answer and explains how to do it
I don't know if that is factor-able. It looks like you could just subtract and get 64t. which would lead to the answer being zero since you divide by zero when isolating the variable t.
Yes, 0.06 is greater than 0.0582.
If we look at the hundreths place, we can see 6 and 5. 6 is greater than 5 which proves that 0.06 is greater.
Best of Luck!
Change in value = 87 - 42 = 45
percentage change = 45/42 x 100 = 107%
