Answer:
The correct answer: 0.05404
Step-by-step explanation:
Given:
Binomial distribution = x
n = 10
and p = 0.09
solution:
P(X=x) =1 0Cx*(0.09^x)*((1-0.09)^(10-x)) for x=0,1,2,...,10
So the probability is calculated by the Formula:
P(X>=3) = 1-P(X=0)-P(X=1)-P(X=2)
putting the given values in the formula
= 1-10C0*(0.09^0)*((1-0.09)^(10-0))-...-10C2*(0.09^2)*((1-0.09)^(10-2))
= 0.0540400
Thus, the correct answer: 0.05404
Answer:
Step-by-step explanation:
So basically what you want to do is start with the distributive property.
-0.5(x+0.3) = 1.6x+0.9(x+4.8) would then equal -0.5x-0.15 = 1.6x+0.9x+4.32.
Then, add the matching terms on the right side (the x values) 1.6x+0.9x =2.5x
Your equation should the look like -0.5x-0.15 = 2.5x+4.32.
Next, add -0.5x to 2.5x giving you 3x
The equation will look like -0.15 = 3x+4.32
After that subtract 4.32 from -0.15 leaving you with -4.47=3x
Divide 3x from both sides
Your answer should be x= -1.49.
