3.15. Use the Miller–Rabin test on each of the following numbers. In each case, either provide a Miller–Rabin witness for the compositeness of n, or conclude that n is probably prime by providing 10 numbers that are not Miller–Rabin witnesses for n. (a) n = 1105. (Yes, 5 divides n, but this is just a warm-up exercise!) (b) n = 294409 (c) n = 294439

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
