Answer:
Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.
Step-by-step explanation:
we know that
The amount of paper needed to make the wrapper is equal to the surface area of the chocolate bar
The surface area of a rectangular prism (chocolate bar) is equal to

where
B is the area of the base
P is the perimeter of the base
H is the height of he prism
In this problem we have

<em>Find the area of the base</em>

<em>Find the perimeter of the base</em>

<em>Find the surface area</em>

Answer:
The land area of Florida is 
Step-by-step explanation:
Let
x -----> the land area of Alaska in square miles
y -----> the land area of Florida in square miles
we know that
The linear equation that represent this problem is equal to
----> equation A
----> equation B
substitute equation B in equation A and solve for y

Remember that
Florida's land area is one-tenth the size of Alaska is the same as to say that Alaska's land area is ten times the size of Florida
Answer:
We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.
Step-by-step explanation:
Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.
In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.
Confidence Interval can be calculated using M±ME where
- M is the sample mean difference between Store A and Store B purchase amounts
- ME is the margin of error from the mean
