Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:

The answer would be 1008. 24x42
Answer:
D
Step-by-step explanation:
The quadratic formula is
.
It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=2, b=16 and c=-9.

We will now simplify and solve.

I think it is 380 but I am not sure
D=26
He already makes 125 a week and you have to take it away because the goal is to get 450 in total
450-125=325
Than you divide it by $12.50 to see how many in total you have to make that will get you to 450
325/12.50=26
so tim has to make 26 desk
d=26.
