The volume is 180.32 because if u multiply those three numbers u get 180.32. Also, what do u mean by SA
Answer:
0.0039 is the probability that the sample mean hardness for a random sample of 12 pins is at least 51.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 50
Standard Deviation, σ = 1.3
Sample size, n = 12
We are given that the distribution of hardness of pins is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =

P(sample mean hardness for a random sample of 12 pins is at least 51)
Calculation the value from standard normal z table, we have,
0.0039 is the probability that the sample mean hardness for a random sample of 12 pins is at least 51.
The answer is 6 hope this helps
Answer:
1/9
Step-by-step explanation:
That's bc there are 9 possible outcomes 0,1,2,3,4,5,6,7,8,
so say an out come is 4, out of 9 chances it was 4 so there is a 1/9 of getting 4
Answer:
n = 3.68
Explanation:
We know that:
1 mg is equivalent to 0.0001 dag
To convert 38600 mg to dag, we will simply use cross multiplication as follows:
1 mg ..............> 0.0001 dag
38600 mg ......> n
n = (38600*0.0001) / 1
n = 3.68
Hope this helps :)
