(6/13)/(6/12)= (6/13)*(12/6)= 12/13
This rule for division applies to all fraction divisions
Answer:
Step-by-step explanation:
Given that
,
The weibull distribution with parameters 
where 

Then,

A) The probability that a specimen's lifetime is at most 250 is

The probability that the specimen's life time is more than 300 is


= 0.0992
b)The probability of the specimen's lifetime is between 100 and 250

c) The value such that exactly 50% of all specimens have lifetimes exceeding that value is

x = 192.07
Let’s try the pythagorean formula.
1) 8^2+15^2=17^2
289=289 Yes
2) 7^2+24^2=26^2
625 ≠ 676 No
3) 6^2+8^2=11^2
100 ≠ 121 No
4) 10^2+24^2=25^2
676 ≠ 625 No
Therefor, 8,15,17 is your answer
Because it gives you an estimate on what the next number in the table will be
