Represent as an exponential function
An exponential function has the form:
Where
and 
Substitute values for a and b, we have:
Convert percentage to decimal
Hence, the exponential function that represents the scenario is:
Answer:
.05x + 30 < 60
Step-by-step explanation:
.05x + 30 < 60
.05 is the cost per text. Since we don't know how many text messages she sends, we have to use x to represent it. We know she pays $30 every month no matter what so, we can write .05x + 30. < means it has to be LESS than $60 NOT EQUAL TO, but less than.
I hope this helps you out!
Answer: (A) randomly selected elements within each of the strata form the sample.
Step-by-step explanation:
Stratified random sampling is a random sampling technique in statistics .
- It includes the partition of the entire population into sub-parts called strata.
- The strata are formed on the basis of the characteristics shared by members .
