(-2 +4)/2 = 2/2 = 1
(-4-6)/2 = -10/2 = -5
midpoint = (1, -5)
Same would need to get at least a 95% on the next test, if he would like to receive a total average of an 80%
Tim spends of his TV time watching badminton.
Step-by-step explanation:
Step 1:
Tim watches a total of 8 sports. He spends of his TV time watching the first four.
So first we need to calculate how much TV time is left to watch the remaining sports.
The TV time left to watch the other sports .
So of his TV time is spent equally on the other 4 sports.
Step 2:
As there are 4 sports remaining, he spends the of his time on all four sports equally. We need to determine what that time is.
The time spent on the remaining four sports .
So Tim spends of his total TV time each on watching formula1 races, tennis, badminton and hockey games. So he spends of his TV time watching badminton.
Three points are collinear if their determinant is equal to 0
So,
| 0 -10 1 |
| -3 -15 1 |
| 2 -6 1 |
We must put 1 at the third column since we don't have z in these points, and 1 is a neutral factor.
Applying sarrus
( 0 . -15 . 1 + -10 . 1 . 2 + 1 . -3 . -6) - (1 . -15 . 2 + 0 . 1 . -6 + -10 . -3 . 1)
(0 - 20 + 18) - (-30 + 0 + 30)
(-2) - (0)
-2
Our determinant is different than 0, so these points are not collinear.
Answer:
C) reflection
Step-by-step explanation:
you can remember flip because reflection and flip both have "fl" in it
