Answer:
5040 ways
Step-by-step explanation:
That is 7 books.
So the number of ways is factorial 7 , written 7!.
= 7*6*5*4*3*2*1
= 5040 ways
Divide both the numerator and denominator by the highest number that can go into both.
26 divide 2 13
----- -----
30 divide 2 15
ans : 13/15 . Whatever is the highest number that can evenly go into both the top and bottom is the number you divide by until you cannot divide it
Answer:
Claim is false
Step-by-step explanation:
Claim : A credit reporting agency claims that the mean credit card debt in a town is greater than $3500.
n = 20
Since n <30
So we will use t test
Formula : 
s = standard deviation = 391
x = 3600
n = 20
Degree of freedom = n-1 = 20-1 = 19
α=0.10
So, using t table
= 1.72
t critical > t calculated
So we accept the null hypothesis
Hence we reject the claim that the mean credit card debt in a town is greater than $3500.
