Answer:
option A
Step-by-step explanation:
To Test
H₀ : μ = 3.75
H₁ : μ ≠ 3.75
now,
If μ = 3.95 then it means H₀ is not true.
then the probability is rejecting the null hypothesis.
Hence, the probability is the power of the test against the alternative μ=3.95
The correct answer is option A
Answer:
108 books.
Step-by-step explanation:
Let the number of magazines = m
Let the number of books = b
<u>Given the following data;</u>
Total number of m & b = 162
<em>Translating the word problem into an algebraic equation, we have;</em>
......equation 1
......equation 2
<em>Substituting equation "1" into equation "2" we have;</em>
m = 54
Now to find the number of books;

Substituting the value of "m" into the equation, we have;
<em>b = 108</em>
<em>Therefore, the total number of books in the library is 108 books. </em>
Maybe it’s -2(46+13) or -92-26v
Simple. just do this:
1000x=1600
x=1600÷1000
x=1.6
each newspaper is $1.60
