Answer:
5 degrees
Step-by-step explanation:
Complementary angles sum up to 90 degrees.
If one angle is 85 degrees, then its complement is (90 - 85), or 5, degrees.
0,-3
To work this out I would use the midpoint formula. (x1+x2)/2 , (y1+y2)/2
Therefore, (3+-9)/2 , (-4+0)/2
= -6/2. , -4/2
= -3 , -2
Now we know the half way point from AB, now we will use the same formula but instead of point B we will substitue the midpoint to work out the 1/4 point
Therefore, (3+-3)/2, (-4+-2)/2
=. 0/2, -6/2
=. 0, -3
Therfore the 1/4 way point from AB is 0,-3
C.
The outlier will have no significant effect on the median of the data set.
Answer:
45 degrees
Step-by-step explanation:
45 is half of 90, 90 is a right angle
Answer:
20
Step-by-step explanation:
The question states that the sample size is 16 and standard deviation of sampling distribution of sample mean also known as standard error is 5. This information can be written as
σxbar=standard error=5 ,n=sample size=16.
We have to find population standard deviation σ.
We know that
<em>Population standard deviation=</em>σ=4*5=20
