Answer:
D. This scenario should be analysed using paired data because the groups are dependent and have a natural pairing.
Step-by-step explanation:
Paired Data can be defined as data set, when sample units of one data set are related to sample units in other data set.
Research Study about spouses number of hours of sleep each night is paired data. As, each man in the male sample group is related to a corresponding woman (his wife) in the female sample group. So, they have a natural paring & they, their sleep schedules are dependent on each other.
It is trustworthy if it is a source that is seen often with a recent date.
Answer:
C. 9
Step-by-step explanation:
The vertex form of the function is given by;
where is the vertex of the parabola.
We substitute a third point say, (3,5) to find the value of a;
The function is
The average rate of change for the interval x=5 to x=6 is
Answer:
I actualy can't see
Step-by-step explanation:
Absolute value is just whatever number wether positive or negitive, and made positive.
This is because aboslust value means the distance from zero, and distance is always positive.
PART A: The equation I used is y<span>≥-1x+4. The line will be graphed going diagonally from the second quadrant to the fourth quadrant and shaded above the line.
PART B: Plug in the coordinates for point C and F into the equation from PART A and solve them to make sure the statements are true. You should end up with 2</span>≥2 for point C and 4<span>≥1 for point F.
PART C: First graph the equation and then shade below the line. Next, identify all the points in the shaded area.
I hope this helps you! I have provided pictures of both equations for reference. The first picture is for PART A and PART B. The second picture is for PART C. Let me know if I'm correct :)</span>
