17 is a prime number whereas 26,44 and 65 are the composite numbers.
<u>Step-by-step explanation:</u>
The number 17 does not belong with 26, 44 and 65.
Here 26 is divisible by 2 and 13.
44 is divisible by 2, 4 and 11.
65 is divisible by 5 and 13
But 17 is divisible by 1 and itself, that is it's a prime number, whereas the other numbers 26, 44 and 65 is divided by 1, itself and also by other numbers.
So 17 is a prime number whereas the 65, 26 and 44 are composite numbers.

Answer:
<em>Y alone can do the piece of work in 30 days.</em>
Step-by-step explanation:
<u>Proportions</u>
Let's make:
N = days for Y to finish the work alone
Since X alone can do it in 15 days, each day he can do a proportion of 1/15 of the piece of work.
Since Y alone can (possibly) do it in N days, each day he can do 1/N parts of the work.
Together, they do
parts of the work per day. We know they can finish it in 10 days, thus:
Rearranging:
The LCM of 10 and 15 is 30, thus operating:
Solving for N:
N = 30
Y alone can do the piece of work in 30 days.
Answer:
291 1/5
Step-by-step explanation:
The probability for a football player to suffer more than three roken bones will be the the sum of probabilities for 4 broken bones and five broken bones. Looking at the chart provided we can see that the probablity for 4 four broken bones is P(4)=0.10, and for 5 broken bones is P(5)=0.15. Thus the probaility,
P(x>3)=0.10+0.15=0.25.
