Answer:
C. -0.97
Step-by-step explanation:
that is the approximate correlation coefficient
I think it’s 15 sorry if I’m wrong
Answer:
5.0645km
Step-by-step explanation:
For the first part of the journey where Vail skied 2 km north, 2 km west
displacement = √2² + (-2)²
displacement = √4+4
displacement = √8
displacement = 2√2 km
d1 = 2√2 km
For the second part of the journey where he skeid 1 km north, and 2 km west. How far was she from her starting point?
displacement = √1² + (-2)²
displacement = √1+4
displacement = √5
d2 = √5 km
Total displacement = d1 + d2
Total displacement = 2√2 + √5
Total displacement = 2(1.4142) + 2.2361
Total displacement = 2.8284+ 2.2361
Total displacement = 5.0645km
Hence she was 5.0645km from her starting point
Answer:
It is <em>a</em> solution, one of an infinite number of solutions.
Step-by-step explanation:
You can check to see if the given point is in the solution set:
4(-4) +5(4) = -16 +20 = 4 > -6 . . . . yes
-2(-4) +7(4) = 8 +28 = 36 > 20 . . . yes
The offered point satisfies both inequalities, so is in the solution set. It is not <em>the</em> solution, but is one of an infinite number of solutions.
