The factored form of this expression would be :
(k-3h)(k+3h).
Answer: 0.6812
Step-by-step explanation:
Let p be the population proportion of trees are infested by a bark beetle.
As per given: p= 12%= 0.12
Sample size : n= 1000
Number of trees affected in sample = 1000
Sample proportion of trees are infested by a bark beetle. = 
Now, the z-test statistic : 
So, 

Hence, the value of the z-test statistic = 0.6812 .
The range refers to the value of y for which x is define.
So let y=f(x),

Try making x the subject to obtain,

x is defined for all real values of y greater than
0.
Hence the correct answer is D.
Answer:
C. -36 3/10
Step-by-step explanation:
4 2/5 = 22/5
22/5 = 4.4
4.4(-8.25)
-36.3 = -36 3/10
