Answer:
15m
Step-by-step explanation:
Answer:
{y,x} = {0,1}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 3x - 3
// Plug this in for variable y in equation [2]
[2] -3•(3x-3) - 9x = -9
[2] - 18x = -18
// Solve equation [2] for the variable x
[2] 18x = 18
[2] x = 1
// By now we know this much :
y = 3x-3
x = 1
// Use the x value to solve for y
y = 3(1)-3 = 0
Answer:
$2.25
Step-by-step explanation:
So if 4 packs of soda costs 9.00 and we need to find how much 1 pack is we divide the total cost by the total amount of packs.
So...
$9/4 = $2.25
So the price for one pack is $2.25
C = 19.99 + 0.15x
1️⃣ C = 0.15(78) + 19.99
2️⃣ C = 11.7 + 19.99
3️⃣ C = 31.69
4️⃣ The total cost is $31.69
5️⃣ The cost to send 78 text messages is $11.70

<u>Representatives: This means that a certain amount of people would constitute what the majority would think too.
</u>1) Tina interviews the school's soccer team about the exercise habits of the students at her school. (implying all the students). This means that Tina only goes to the soccer team instead of the whole school to find out the whole school's exercise habit.
<u></u>2) Alana also counts as representatives, because she did not interview ALL of the teachers, rather just a selected majority (in this case)
5) For Jeremy, he only interviews 5 students from each class rather than all students<u>
Not Representatives: Each person is given a choice of opinion and does not affect other people.
</u>3) Joe talks to fathers of high school students, which could be larger than just 'representatives', and implies a larger group of people, and is not as selective as having representatives
<u />4) Social Media constitutes of a large group of people, generally larger than a school, and if people take time to take the survey, it will generate a larger test-group. Also, everybody answering the survey would take time to think about themselves, and only represent themselves, and not others.
hope this helps
