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:
60cm³
Step-by-step explanation:
Answer:
9.6 ounces
Step-by-step explanation:
Step 1
We find the amount of ounces of Almonds
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are almonds.
Hence,
The amount of almonds = 0.20 × 24 ounces
= 4.8 ounces
Step 2
We find the amount of ounces of hazelnuts
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are hazelnuts.
Hence,
The amount of hazelnuts = 0.20 × 24 ounces
= 4.8 ounces
Step 3
Therefore, the total amount of almonds and hazelnuts in the can is
4.8 ounces + 4.8 ounces
= 9.6 ounces
