Answer:
The value is not close to 0.3 because of sampling variability.
Step-by-step explanation:
The group of answer choices are not given which are as follows:
- All of the above
- Because the sample size is too small
- Because of sampling variability
- Because of nonresponse bias
From this the correct option is option C which is Because of Sampling Variability.
This is true because the two populations are of different values and thus the sample is not dependent on any one of the two possibilities. When a sample of 4 is considered from first and 400 from the second the overall probability will be far from the value of 0.3. So the
Answer:
-25
Step-by-step explanation:
formula for areas of rectangles= width x height
width=x-5
height=x+5
(x-5)(x+5)=
-5x+5x-25
since the 5x's cancel out each other
=
-25 will be the answer
Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:

lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).
Hope this helps!
Just add. 6.5+12.3= 18.8 then subtract 20-18.8= 1.2. She needs 1.2 mores yards
