Step-by-step explanation:
Notepads of the same color = 4
As we have two sizes then total for the same color =
Notepads of the different colors as we have to choose 3 different colors out of 4 = 4C3 = 4
For two sizes the total for the different color =
We can group these like - Same size same color package:
There are eight combinations
Size 1:
BBB
GGG
YYY
PPP
Size 2:
BBB
GGG
YYY
PPP
Next groups form like : Same size different color
Size 1:
BGY
BYP
GYP
BGP
Size 2:
BGY
BYP
GYP
BGP
So, we get total =
Using the normal distribution, it is found that 2.64% of all the nails produced by this machine are unusable.
In a <em>normal distribution</em> with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 3 inches, hence .
- The standard deviation is of 0.009 inches, hence .
Nails that are <u>more than 0.02 inches</u> from the mean are unusable, hence:
The proportion is P(|Z| > 2.22), which is <u>2 multiplied by the p-value of Z = -2.22</u>.
Z = -2.22 has a p-value of 0.0132.
2 x 0.0132 = 0.0264
0.0264 x 100% = 2.64%
2.64% of all the nails produced by this machine are unusable.

Answer:
9 minutes per mile.
Step-by-step explanation:
3 miles takes 27 minutes, so:
1 mile takes 27/3 = 9 minutes.
