Answer:
Standard error = 5.4
Step-by-step explanation:
We are given that Population Mean, 
= 150 and Population Standard deviation, 
= 27 and sample size, n = 25
Standard error formula for the sampling distribution of this sample mean is given by;
<em> Standard error</em> = 
= 
= 5.4
(2,-2) would be the answer I think
Answer:
x = 29
Step-by-step explanation:
If the lines are parallel
< CBA = < DAB due to the fact that they are alternate interior angles
42 = DAB
We also know that
DAB + BAC + CAE = 180 since they form a straight line
Substituting the given values
42+ 109 + x = 180
Combine like terms
151 + x = 180
151+x-151 = 180-151
x = 29
Answer:
60
Step-by-step explanation:
210÷3.5=60
3.5x60=210
Hope this helps!

Applying the properties of a kite, m∠WZY = 128°.
<h3>Properties of a Kite</h3>
- The diagonals of a kite bisect each other perpendicularly.
- The main diagonal bisects the opposite angles.
Given:
m∠ZWY=41∘
m∠XYW=11∘
m∠WZY = (180 - 90 - 41) + (180 - 90 - 11)
m∠WZY = 49 + 79
m∠WZY = 128°
Therefore, applying the properties of a kite, m∠WZY = 128°.
