The annual rainfall (in inches) in a certain region is normally distributed with µ = 40 and σ = 4. What is the probability that
Allushta [10]

Answer:

P( That it will take over 10 years or more of a year with a rainfall above 50inches) = (0.9938)^10

Step-by-step explanation:

Since the annual rainfall is normally distributed,

Given: that

Mean (µ )= 40

and σ = 4.

Let X be normal random variables of the annual rainfall.

P(that there will be over 10 years or more before a year with a rainfall above 50 inches)

P(>50) = 1-P[X ≤50]

1 - P[X- μ/σ ≤ 50 - 40/4]

=1 - P [Z≤ 5/2]

=1 -Φ(5/2)

=1 - 0.9939

= 0.0062

P( the non occurrence of rainfall above 50 inches)

= 1-0.0062

=0.9938

ASSUMPTION:

P( That it will take over 10 years or more of a year with a rainfall above 50inches) =(0.9938)^10

X^4 = 24<br> Solve for x
Ganezh [65]
Take the fouth square root of both sides
\sqrt[4]{{x}^{4} }  =  \sqrt[4]{24}
so
x =  \sqrt[4]{24}  \: or \:  x =  -  \sqrt[4]{24}

What is the solution(s) for: 10n^2+n^2+16=0
Svetlanka [38]

Answer:

n = (4 i)/sqrt(11) or n = -(4 i)/sqrt(11)

Step-by-step explanation:

Solve for n:

11 n^2 + 16 = 0

Subtract 16 from both sides:

11 n^2 = -16

Divide both sides by 11:

n^2 = -16/11

Take the square root of both sides:

Answer: n = (4 i)/sqrt(11) or n = -(4 i)/sqrt(11)
