Answer:
-12°C
Step-by-step explanation:
6AM = 2°C
8AM= -2°C
10AM= -6°C
12AM= -8°C
2PM= -12°C
-98 is answer
If -98 is divided by 7
-98/7 = -14
We get -14
Which is 6 less than -8
As, -8 - 6 = -14
Random sampling is when you select a random group of people for something.
Ex. Out of a population of 259,096 people, a random sample of 400 people are choosen.
Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).
_____
If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.
