The cost of the brand less than 6 bags is less than 11.94
<h3>Functions and equations</h3>
If the cost y of a brand can be represented by the equation y=1.99x
where
- x represents the number of bags.
For a brand that costs less than 6 bags, we will substitute x = 6 into the function
y = 1.99(6)
y = 11.94
Hence the cost of the brand less than 6 bags is less than 11.94

Answer:
DF = 458
Step-by-step explanation:
In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.
The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;
DF = n - 1
where n is the sample size
Given n is 459, DF = 459 - 1 = 458
Therefore, DF = 458
<u>answer</u>:
sale price: $5
<u>explanation</u>:
