What is the greatest prime you must consider to test whether 575 is prime

Hello from MrBillDoesMath!

 23

Discussion:

We only need to check primes less that the square root of 576, which is about 23.98. As 23 is a prime number, it is the answer to the question.

Another way of looking at this: the primes less than or equal to 23

(23*23 = 529)

2, 3, 5,7,11,13,17,19,23

The greatest prime in the list is 23

Thank you,

MrB

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer: it is a.,b.,d.
