A company famous for its nacho-flavored corn chips has developed two new formulas, A and B, which they hope their customers will like even more than the original formula. To determine whether customers prefer one of the new formulas over the current nacho flavoring, a sample of 50 customers is obtained. Each customer tastes both formula A and formula B in a randomly assigned order and indicates which one they prefer more. Which of the following best describes this study?a. This study is not well designed because there is no replication. Each customer tasted the formulas only once.
b. This study is not well designed because formulas A and B are not compared with the original formula.
c. This study is not well designed because the sample may not have been randomly selected.
d. This study is not well designed because each customer should taste the two new formulas in the same order.
e. This study is not well designed because there is not enough replication with only 50 customers.

b. This study is not well designed because formulas A and B are not compared with the original formula is the best descriptionfor this study

Step-by-step explanation:

This study was mainly conducted to know about the customer's preference for a new formula of corn chips which related with the original formula ., whether the customer's like the new formula than the old one.,so the company must include the old formula along with the two new formula's for customer's consideration. But .,Here they introduced and tested only the new formula's.,

So.,

Comparison of all the three formulas is must., to know about the exact preference of customer's on new formula's than the old formula.,so option b is preferable

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
