Answer:
a. A frame is a list of individuals in the population being studied.
Step-by-step explanation:
We are asked to choose the correct definition of frame from our given choices.
We know that a frame, in statistics, is a list of all those within a population who can be sampled. It may include individuals, households or institutions.
We also know that a frame is the source material or device from which a sample is drawn.
Upon looking at our given choices, we can see that option 'a' is the correct choice.
Since the translation is 8 units right and 4 units down, we have to add 8 to the x coordinate and subtract 4 to the y coordinate.
R=(-2,1)
R' = (-2+8,1-4)= (6,-3)
R' = (6,-3)
Answer:
A: 40 degrees
Step-by-step explanation:
Since every triangle is 180 degrees, you can start off by subtracting 50 from 180 since that side does not contain a y for you to solve.
Since the other two sides do have a y in them, you would set 130 degrees equal to y+10 and 2y:
130=y+10+2y
Then you would isolate the y's by subtracting 10, and you would add y and 2y together to get:
120=3y
Finally, you would divide 120 by 3 to get your answer, 40=y.
Hope this helps!
Answer:
The width is 5 meters
Step-by-step explanation:
The rectangular field is 24 meaning adding just one width and length of the rectangle would be 12.
x = width
2x - 3 + x = 12
3x - 3 = 12
3x - 3 + 3 = 12 + 3
3x = 15
x = 5
