A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will amount to $17,750 . The variable costs will be $12.75 per book.
Step-by-step explanation:
Answer: -69q+74
Step by step:
1. Use distributive property.
8⋅10+8(−6q) + 3(−7q − 2)
Multiply 8 • 10 then -6 • 8
80 - 48q + 3(-7q - 2)
2. Use distributive property again.
80 - 48q + 3(-7q - 2)
Multiply -7 • 3 then 3 • -2
80 - 48q -21q - 6
3. Simplify
Subtract 6 from 80 then subtract 21q from -48q.
-69q + 74
8(10 - 6q) + 3(-7q - 2) = -69q + 74

Answer:
As a general rule of thumb, a small confidence interval is better. The confidence interval will narrow as your sample size increases, which is why a larger sample is always preferred. As our page on sampling and sample design explains, your ideal experiment would involve the whole population, but this is not usually possible.
Step-by-step explanation:
Answer:
Lets assume a polynomial
Here GCF is 5z
all terms are divisible by 5z. so greatest common factor is 5z
One form of polynomial is
We factor the polynomial further
Other form of polynomial is
and are the two forms of polynomial
First form is created by taking out GCF 5z
