When 4 and a number n are multiplied, the result is 36: 4n = 36
Isolate the variable. Note the equal sign. What you do to one side, you do to the other. Divide 4 from both sides
(4n)/4 = (36)/4
n = 36/4
n = 9
9 is your answer for n

X^2-9/x^2-6x+9 = (x-3)(x+3) / (x-3)^2 = x+3/x-3
Step-by-step explanation:
The radius of a cylinder, r = 13 feet
Height of the cylinder, h = 28 feet
The circumference of the cylinder is given by :
The area of one base is given by :
The lateral area of the cylinder is given by :
Total surface of the cylinder is given by :
The total surface area of the cylinder is not matched with the given data. Hence, option (4) is not correct.
he events are not independent
<h3>How to determine if they are mutually exclusive?</h3>
The given parameters are:
P(A) = 0.2
P(B) = 0.2
The events are mutually exclusive.
So, as have
P(A or B) = P(A) + P(B)
If the events are independent, then
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = P(A) * P(B)
So, we have
P(A and B) = 0.2 + 0.2 - 0.2 - 0.2 = 0
P(A and B) = 0.2 * 0.2 = 0.04
The above equations are not equal
Hence, the events are not independent
