An instructor wants to test whether attending class influences how students perform on an exam. There are 54 students in the class. There are 25 students who attended the class and passed the exam, 6 students who attended class and failed the exam, 8 students who skipped the class and passed the exam, 15 students who skipped the class and failed class. Please perform a statistical test and indicate whether attending class influence the exam performance

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

yes. we do proportions in probabilities.

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
