Answer:
The greatest common factor is 5.
Step-by-step explanation:
The prime factorisation of 10, 30 and 45 is,
10 = 2 × 5
30 = 2 × 3 × 5
45 = 3 × 3 × 5
The prime factor '5' is common in the factorisation of 10, 30 and 45
So, the greatest common factor of 10, 30 and 45 is 5.
Answer:
25th percentile = 202
80th percentile = 285
Step-by-step explanation:
Rearranging the values in increasing order

N = total number of variables = 15.
25th percentile = [(N + 1)/4]th variable = (15 + 1)/4 = 4th variable.
So, the 25th percentile = 4th variable = 202.
80th percentile = 0.8(N + 1) th variable = 0.8 × (15 + 1) = 12.8th variable = 13th variable = 285
