Answer:
Casey will take 3 minutes to clean 
part of the section.
Step-by-step explanation:
∵ Casey takes the time to cleans 
of a section = 1 minute
∴ He will take the time to clean complete section = 
= 
= 3.6 minutes
Now time taken to clean part of the section = 
= 3 minutes
Therefore, left part of the section will be cleaned by Casey in 3 minutes.
Using the normal distribution, it is found that the correct option is:
- P(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces
In a normal distribution 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:
- Mean of 20 ounces, hence
.
- Standard deviation of 2.3 ounces, hence
P(Y < 16) is the <u>p-value of Z when X = 16</u>, hence:
has a p-value of 0.041.
This is valid for the entire population, hence, the correct interpretation is:
- P(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces

Yes, because if you devide 2 by 5 it equals a decimal of .4

Answer:108.54
Step-by-step explanation:
Answer:
if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6
we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls
