CHEMISTRY A solution must be diluted so it can be used in an experiment. Adding a 4-molar solution to a 10-molar solution will decrease the concentration.
500+ 4.1
The concentration C of the mixture can be modeled by C (2) =
50+
where x is the number of liters of 4-molar solutions added.
a) Determine whether the function is continuous at x = 10.
Determine whether the function is continuous at x=10

Amanufacturing firm has been averaging 16.8 orders per week for several years. however, during a recession, orders appeared to slow. suppose the firm’s production manager randomly samples 31 weeks and finds an average of 15.6 orders with a standard deviation of 2.3 orders. using a 0.025 significance level, test whether the mean number of orders has decreased. type the full 5 step procedure into the answer box, then for multiple choice practice, answer the following: 1. what is the name and symbol of the parameter that you are testing? 2. what is the symbol and value of the point estimate of that parameter? 3. what distribution are you using to test this parameter? 4. what is the critical value? 5. what is the test statistic value? 6. what is the p-value?
