Answer:
Katrina will have to pay $21.02 this month.
Step-by-step explanation:
The cost per text message = $0.19
Last month credit = $9.50
The number of text messages sent this month = 158
So, the total cost of 158 texts = 158 x cost per text
= 158 x $0.19 = $ 30.52
So, her total bill = The amount spent on texts - The credit amount
= $ 30.52 - $9.50 = $21.02
So, Katrina will have to pay $21.02 this month.
1. x is less then or equal to -1 or x is greater then or equal to 5.
2. x is greater then -4 and x is less than or equal to -1
The reason it is equal to or not is because above the original number there is a dot. If it is not filled in, it is considered open. This would leave it as greater than or less than. If it were filled in, it would be considered closed. Leaving it as greater than or equal to or less than or equal to.
I think the answer is A) stratified random sampling! Stratified random sampling is when sunsets of individuals are created based on similar criteria, which sounds the closest to the problem because stratified can split a group and does not have to be fully equal.
Non random sampling doesn’t fit because it’s clearly stated that it’s random.
Systematic random sampling is based on intervals in a group.
The next closest answer would be simple random, which is when a subset of individuals are chosen from a larger group with all having the same probability.
The answer is associative property of multiplication
