Answer:
a) The value of A = 2
b) The value of
Step-by-step explanation:
a)
Given that:
X should be the random variable that assumes only positive integer values.
The probability function; for some constant A and n ≥ 1.
Then, let
This implies that:
A = 2
Thus, the value of A = 2
b)
Suppose X represents a e constant A (n> 1). Find A.
b) Let X be a continuous random variable that can assume values between 0 and 3
Then, the density function of x is:
where; B is constant.
Then, using the property of the probability density function:
Taking the integral, we have:
B [ 9 +3 ] = 1
B [ 12 ] = 1
Divide both sides by 12
Answer:
either x = 1.75 or x = 700 , question wasn't clear
Step-by-step explanation:
Because you put the x in front of 20 , you might be meaning x/20 (second answer listed)? Or, you put the variable on the wrong side of 20. (first answer listed)
If you meant to type 20x
35 = 20x
÷20 ÷20 *
1.75 = x
*divide both sides by 20 to isolate x
x = 1.75
(x = )
--------------------------------------------------------------------------
If you meant to type x/20
35 =
·20 ·20 *
700 = x
*multiply both sides by 20 to isolate x
700 = x
Answer:
Slant height = 33 inches
Step-by-step explanation:
r = 12 inches
Lateral Surface Area of cone = 396π square inches
πrl = 396π
π * 12 * l = 396π
l = 33 inches
