Answer:
a) Standard deviation: 3 bluberries
b) We assume, to apply this rule, that the distribution of blueberries per muffin has a bell-curve distribution, approximately normal.
Step-by-step explanation:
We know that the number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries.
a) If we use the Empirical Rule 68-95-99.7, specifically the last term, we have that:
- 99.7% of the data will fall between 3 standard deviations from the mean.
Then, if we consider the range of 20 to 40 containing 99.7%, we can calculate the standard deviation as:
Answer:
x = 30
F = 130
G = 50
Step-by-step explanation:
f and g are supplementary which means they add to 180
5x-20 + 3x - 40 = 180
Combine like terms
8x - 60 = 180
Add 60 to each side
8x-60+60 = 180+60
8x = 240
Divide by 8
8x/8 = 240/8
x = 30
F = 5x -20 = 5*30 -20 = 150 -20 = 130
G = 3x-40 = 3*30 -40 = 90-40 = 50
Well, Gina makes quite a bit to be a waitress...but let's focus on the math!
We can make an equation based on the information given to us...
$6.00 per hour
PLUS tips
Now, notice how <u>6.00 is a constant</u>, it never changes.
Her tips and her hours do change, however, so they must be made into variables.
We can form the equation 6(times how many hours) + (tips)
OR
<em>6x + y = z</em>
X - hours
Y - tips
Z - total money earned
Now we know what the variables mean, let's put these into action!
6(37) + 43 = Z?
Simplify: 6 * 37 = $222.00.
222 + 43 = Z
Simplify: 222 + 43 = $265.00
The total amount she earned altogether is $265.00!

<h3>Answer: 18%</h3>
==================================
Explanation:
Locate the "receives aid" column and "graduate" row. The value 1879 is in this row and column combo.
There are 10730 students total as shown in the bottom right hand corner.
Roughly 1879/10730 = 0.1751 = 17.51% of the students are graduates who receive aid. This rounds to 18%
