The true statements are:
A. Tree A's heights are less spread out than tree B's heights and
B. Tree A has lower average height than tree B
Explanation:
Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.
The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.
If by solve the equation, you mean solve for p, then no problem.
5p - 14 = 8p + 4
5p - 18 = 8p
-18 = 3p
-6 = p
Your answer should be -6
Product of odd number of negative terms is negative.
Hence, I have given all the 8 possibilities.

Answer:
The two solutions are given as and
Step-by-step explanation:
As the given equation is
So the corresponding equation is given as
Solving this equation yields the value of m as
Now the equation is given as
Here m1=-8, m2=1 so
The derivative is given as
Now for the first case y(t=0)=1, y'(t=0)=0
So the two equation of co-efficient are given as
Solving the equation yield
So the function is given as
Now for the second case y(t=0)=0, y'(t=0)=1
So the two equation of co-efficient are given as
Solving the equation yield
So the function is given as
So the two solutions are given as and
