F) t-test for proportion
Answer:
B) Paired Z-test for means
Step-by-step explanation:
We are told that the distances travelled are normally distributed.
We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.
Also, the standard deviation of both cases are known.
Thus, this is where Paired Z-test for means is used.
My friend is obviously wrong. If I'm paying $2.40 for three fourths of a pound, what makes him think that he'll pay less for more grapes? This equation actually doesn't involve any equations.
Answer:
1.) a line parallel to the line will have slope 2/3
2.) a line perpendicular to the line will have slope -3/2
Step-by-step explanation:
The slope of parallel lines must always be the same. Therefore, if a line is parallel to y = 2/3x - 4, the other line must have slope 2/3 and not have the same y-intercept (otherwise it would represent the same line).
The slope of perpendicular lines are reciprocals with opposite signs. Basically, if you have one slope of one equation, to find the perpendicular slope you would simply flip the slope over and change the sign.
For example: if the slope was 2/3, the perpendicular slope is flipping 2/3 upside down to get 3/2 and changing the sign from positive to negative = -3/2
Answer: (2,4)
Step-by-step explanation:
Vertex
|0-2| = 0
|-2| = 0
The graph is shifted 4 units up so therefore (2,4) is the vertex
