This is a tree diagram of the possibilities listed. Hope this helps!
We have to evaluate the summation of (3n+2), with n ranging from 1 to 14. Let's write all the terms of the sum for each value of n:
n=1:
n=2:
n=3:
n=4:
n=5:
n=6:
n=7:
n=8:
n=9:
n=10:
n=11:
n=12:
n=13:
n=14:
Now, let's sum all the terms together, and we get:
Answer:
a) 0.345
b) 0.005
Step-by-step explanation:
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:
Step-by-step explanation:
(1/2)(m)(n) - 5(p)
This is an expression, not an equation.
X = 8.
2 (8) -4 = 12. LM=12
