Answer:
0.561
Step-by-step explanation:
To solve this problem we must resort to external information that I will leave attached with the answer, it is a table that for each value of n, gives us the critical values.
Returns the critical values for both the significant levels of 0.01 and 0.05.
If we go to the table we know that when n = 20 and the significant level is 0.01, the corresponding critical value is: 0.561
First, divide the shape into two shapes: the trapezoid on the very top and the large rectangle that makes up most of the bottom. Then, find the area of each, and add them together for the total area.
<u>Trapezoid:</u>
A=0.5(b1+b2)h
A=0.5(7+14)5
A=0.5(21)5
A=52.5
<u>Rectangle:</u>
A=lw
A=12(14)
A=168
52.5+168=220.5
The area is 220.5 square feet.
Hope this helps!!

Answer:
C, D and E
Step-by-step explanation:
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.
solve 3x(x - 1)(x + 5) = 0
Equate each factor to zero and solve for x
3x = 0 ⇒ x = 0
x - 1 = 0 ⇒ x = 1
x + 5 = 0 ⇒ x = - 5
Vertical asymptotes at x = -5, x = 1 and x = 0
