We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 0.3
We are given that the distribution of lengths of lumber is a bell shaped distribution that is a normal distribution.
Formula:
a) P(length greater than 100.12 inches)
P(x > 100.12)
Calculation the value from standard normal z table, we have,
b) Standard error due to sampling:
P(length greater than 100.12 inches for the sample)
P(x > 100.12)
Calculation the value from standard normal z table, we have,

Answer:
One Solution
Step-by-step explanation:
So we have the equation:
On both sides, combine like terms:
Simplify:
Subtract x from both sides. The left cancels:
Subtract 3 from both sides. The right cancels:
Flip:
So, our equation only has one solution.
And the answer is -1 :)
Answer:
$5.00
Step-by-step explanation:
The main course is twice the cost of the appetizer, so $4.95 x 2 = $9.90
