The probability of a randomly selected hard drive from the company lasting between 2 years 3 months and 3 years 3 months is 32.22%
Given here,
Mean (μ) = 3 years 6 months
= (3×12)+6 = 42 months
Standard deviation (σ) = 9 months
We will find the z-score using the formula: z = (X - μ)/σ
Here X₁ = 2 years 3 months
= (2×12)+3 = 27 months
and X₂ = 3 years 3 months
= (3×12)+3 = 39 months
So, z (X₁ =27) =
and z (X₂ =39) =
According to the standard normal table,
P(z> -1.666...) = 0.0485 and P(z< -0.333...) = 0.3707
So, P(27 < X < 39)
= 0.3707 - 0.0485
= 0.3222
= 32.22 % [Multiplying by 100 for getting percentage]
So, the probability of a randomly selected hard drive from the company lasting between 2 years 3 months and 3 years 3 months is 32.22%
4 times 16 = 64. If the square has the same volume as 64, you find the square root of 64.
8 is the length of the side of the square.

Answer:
b = 65 degrees
Step-by-step explanation:
As we can see, the line that angle b and 115 deg correspond to is a straight line. A straight line <em>always</em> measures at 180 deg.
Because of this principle, we know that:
We can simplify this one variable equation now:
Now solve:
And this makes sense. Just by eyeballing the angle, we can see that it is under 90 degrees.
So, b = 65 degrees
