Answer:

Step-by-step explanation:
the information we know about the shape of the stick of butter:



The formula for the volume of a rectangular prism is:

we find the volume by multiplying ll the measurements of the stick.
So we substitute the values to find the volume and we get the following:

the volume of the stick of butter is 
Answer:
0.55199
Step-by-step explanation:
When we have a random number of samples, We solve using z score formula
z = (x-μ)/σ/√n where
x is the raw score
μ is the population mean
σ is the population standard deviation
n is random number of samples
z = 0.83/77/√147
z = 0.13069
Probabilty value from Z-Table:
P(x<48.83) = 0.55199
The probability that the mean of the sample would differ from the population mean by less than 0.83 months is 0.55199
If you don't know what the variable is before you do the equation, you'll end up with an answer that doesn't make sense.<span />
