Well first you have to find the unit rate, or how many "p" each pencil costs. So you take 54 and divide it by 6, and you get 9. So each pencil costs 9 p, so you take 9 and multiply it by 8. That gets you 72, so 8 pencils cost 72p.

Step-by-step explanation:
Answer:
The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.
Step-by-step explanation:
The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.
For a normal curve, the mean, median and mode are the same and represents the center of the distribution.
The center of the normal curve below is at the height 63 inches.
Thus, the mean of the distribution of heights of students at a local school is 63 inches.
The standard deviation represents the spread or dispersion of the data.
From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.
So, the standard deviation is 4 inches.
13 is the answer. So, 1/10 of 1/10 of 1/10 of 3,000 is 3, +10= 13.
