Step-by-step explanation:
Let Freddy could arrange n catalogs on the shelf.
The dimension of the shelf is:
72 over 5 inches wide.
The dimension of the catalog is:
4 over 5 of an inch thick.
n × Dimension of one catalog=Dimension of shelf.
i.e.
n×(4 over 5 inches)=72 over 5 inches
i.e.
n=72 over 5 inches/ 4 over 5 inches
i.e.
n=72/4

lbvjy [14]

Answer:

p-value = 0.369

Step-by-step explanation:

Test of hypothesis which has its the alternative hypothesis as Ha:μ1−μ2≠0 is a two tailed test. Therefore, P-value for a two-tailed test with test statistic t≈−0.90 and the number of degrees of freedom = 208

P-value = 2 X P( t(208) < - 0.90)  

    = 2 X 0.1846

    = 0.369

Fraction : 3/11+7/15= <br> Please show me how you got the answer
avanturin [10]
So the first thing you would have to is to find a common denominator so a common denominator between 11 and 15 is 165. 3/11 * 15 =45/165  next you would do 7/15 * 11=77/165 no that both denominators are the same we add the numerator but the denominator stays the same so 45/165 + 77/165 = 122/165
and since it can't be reduced any more 122/165 is your answer. 

hope this helps :)
