Soda is often packaged in cans that are supposed to contain 12 ounces. However, no
manufacturing plant is perfect and so there might be slight errors. For example, Sam's Splendid
Soda company has verified that the amount of soda in their cans has a normal distribution with
a mean of 12 ounces and a standard deviation of 0.7 ounces. Although this is made up, it's not
completely divorced from the truth.
1. You open a can of Sam's and realize there are only 11.6 oz in the can. What is the
probability that a single can will contain 11.6 ounces or less of soda? (2 points)
2. Troubled by the under-filled soda, you decide to empty out all the cans in a six pack of Sam's
Soda and find that the mean amount of soda in all the cans is 11.6 ounces. What is the
probability that six pack will have a mean of 11.6 ounces or less of soda? (2 points)
3. Not satisfied with the information you figured out in #2, you take a case (36 cans) and
empty out all the cans of Sam's Soda and find that the mean amount of soda in all the cans is
11.6 ounces. What is the probability that case will have a mean of 11.6 ounces or less of soda?
(2 points)
4. Draw three normal distributions on the same set of axes or with the same scale to show
how the probabilities decrease from one can to six cans to 36 cans even though we're looking
at "less than 11.6 ounces." (2 points)
5. Use the graphs and your own understanding of the Central Limit Theorem to write a few
sentences explaining what is happening here. (2)
The probability that a single can will contain 11.6 ounces or less of soda is 0.2843
Probability that a can contains 11.6 ounces or lessThe given parameters are:
x = 11.6
Mean = 12
Standard deviation = 0.7
Calculate the z value using:
[tex]z = \frac{x - \bar x}{\sigma}[/tex]
This gives
[tex]z = \frac{11.6-12}{0.7}[/tex]
z = -0.57
The probability is then calculated as:
P(x ≤ 11.6) = P(z ≤ -0.57)
Using the z table of probabilities, we have:
P(x ≤ 11.6) = 0.2843
Probability that a pack contains 11.6 ounces or lessIn (a), the probability that a can contains 11.6 ounces or less is 0.2843
The probability that all cans in a pack contains 11.6 ounces or less is
P(6) = 0.2843^6
P(6) = 0.00053
Probability that a case contains 11.6 ounces or lessIn (a), the probability that a can contains 11.6 ounces or less is 0.2843
The probability that all cans in a case contains 11.6 ounces or less is

16. You found a shortcut to school that saves 5 minutes off of taking the freeway. About 1 in every 10 trips
you get stuck behind a bus and it ends up taking you 20 minutes longer than the freeway. What is the expected
value of the shortcut?
Answer:
it saves 2.5 minutes
Step-by-step explanation:
The expected value of a random variable is the sum of products of possibilities and the probability of each.
Here, you have a probability of 0.9 of saving 5 minutes, and a probability of 0.1 of adding 20 minutes.
__
The expected value of the shortcut is ...
0.9(-5) +0.1(20) = -4.5 +2.0 = -2.5
The shortcut is expected to save 2.5 minutes on average.

The probability of 0.9 comes from the 9 of 10 trips that result in a time saving.

The equation of Q(n) is [tex]Q(n) = \frac89 * (88n + 23)[/tex]
How to determine the formula of Q(n)?The functions are given as:
[tex]R(d) = \frac89 d[/tex]
[tex]P(n) = 88n + 23[/tex]
From the question, we understand that:
d = P(n)
This means that:
d = 88n + 23
Substitute d = 88n + 23 in R(d)
[tex]R(n) = \frac89 * (88n + 23)[/tex]
Also, from the question
Q(n) = R(n)
So, we have:
[tex]Q(n) = \frac89 * (88n + 23)[/tex]
Hence, the equation of Q(n) is [tex]Q(n) = \frac89 * (88n + 23)[/tex]

32 pints of each of the two existing types of drink must be used to make 40 pints of a mixture that is 45% pure fruit juice.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let x be the pints of 60% pure fruit juice
0.60x + 0.35(40 - x) = 0.40(40)
x = 8
= 40 - 8 (pints of 35% juice)

by what percent will the fraction change if its numerator decreased by 20 and its denominator is decreased by 60
I consider the original fraction: x/y.
If the numerator "x" increases by 20%, it can be interpreted in this way:
"x" represents 100% (the unit) and when increasing by 20% we have that the value of "x" becomes 120%
120% of "x" is [tex]\bf{\frac{120*x}{100}=1,2x }[/tex]
This is what we have left in the numerator.
By the same reasoning, in the denominator "y" remains:
100% - 40% = 60% of "and"
60% of "y" is...[tex]\bf{\frac{60*y}{100}=0.6 y }[/tex]
The new fraction is: 1,2x / 1,6y.
...simplifying by dividing top and bottom by 0.6,... 2x / y
To find out the percentage by which the original fraction has changed, we first find the relationship or ratio between the original fraction and the new fraction with the fraction quotient:
[tex]\bf{\dfrac{\frac{2x}{y} }{\frac{x}{y} }=\frac{2xy}{xy}=2 }[/tex]
... that is to say that the new fraction has doubled in relation to the original.
Therefore, the percentage of variation per increase is 100%.
Pisces04A contemporary building has a window in the shape of a parallelogram with a base of 90 in and an adjacent side of 40 in. How many inches of trim are needed to surround the window?
260 inches of trim are needed to surround the window.
What is the surface area?The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.
Actually, all we need is a trim that is the same size as our window and equal to the parallelogram's circumference, which is
The sum of the side is;
⇒Length of lower side + Length of the upper side
⇒ 90+90
⇒180 inches
The sum of adjacent sides;
Sum of adjacent sides = 40+40
Sum of adjacent sides = 80 inches
The length you should trim is needed to surround the window is found as;
⇒ 180 inches + 80 inches
⇒260 inches
Hence,260 inches of trim are needed to surround the window.

By writing Z in polar form, we will see that:

How to get the value of Z³?
First, we can see that:
z = (-1 - i)
If we write it in polar form, we get:
[tex]z = \sqrt{2} *e^{i(\pi + \pi/4)[/tex]
If we apply the power 3, we get:
[tex]z^3 = (\sqrt{2} *e^{i(\pi + \pi/4)})^3\\\\z^3 = 2^{3/2}*e^{i*(3\pi + 3\pi/4)}\\\\z^3 = 2^{3/2}*e^{i*15\pi/4}[/tex]
Notice that:
[tex]\frac{15\pi}{4}[/tex]
Is an angle equivalent to:
[tex]\frac{15\pi}{4} - 2\pi = \frac{15\pi}{4} - \frac{8\pi}{4} = \frac{7\pi}{4} = 1.75\pi[/tex]
