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,
Volume of a cone (V) = (1/3) · π · r² · h
270 = (1/3) · π · r² · h
810 = π · r² · h
(810)/(π · r²) = h
257.83/r² = h
Answer:
y = 26
Step-by-step explanation:
Write the direct variation equation.
y = ax
Substitute y for 6 and x for 4.
The new equation is:
6 = a(4)
Simplify:
6 = 4a
Divide by 4 on both sides to get a = 6/4.
________________________________
y = 6/4(24), 6/4 x 24 is 104/4. 104/4 is 26.
y = 26
