Answer:
? = 13
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
? = = 13

Answer: 0.0473
Step-by-step explanation:
Given : The proportion of gambling addicts : p=0.30
Let x be the binomial variable that represents the number of persons are gambling addicts.
with parameter p=0.30 , n= 10
Using Binomial formula ,
The required probability =
Hence, the required probability = 0.0473
Answer:
Step-by-step explanation:
Given that:
The differential equation;
The above equation can be better expressed as:
The pattern of the normalized differential equation can be represented as:
y'' + p(x)y' + q(x) y = 0
This implies that:
Also;
From p(x) and q(x); we will realize that the zeroes of (x+2)(x-2)² = ±2
When x = - 2
Hence, one (1) of them is non-analytical at x = 2.
Thus, x = 2 is an irregular singular point.
