Answers
The weight of a randomly selected party size bag of tortilla chips coming off an assembly line is normally distributed with mean = 16.3 ounces and standard deviation = 0.2 ounces. Suppose we pick 4 bags at random and the sample mean = 16.26. The actual sampling error is 0.04 ounces and the typical sampling error is 0.05 ounces.
What is sampling error? The difference between a population parameter and its corresponding sample statistic is known as sampling error. It's also called estimation error. Sampling error can occur in any type of experiment or study when a sample of data is used to estimate a population's parameters or characteristics. The greater the sample size, the smaller the sampling error; the smaller the sample size, the greater the sampling error.
The sampling error formula is:
Sampling error = sample statistic - population parameter.
What is the actual sampling error?
To compute the actual sampling error, we use the formula:
Actual Sampling Error = Sample Mean - Population Mean.
Given the data we have, Sample Mean = 16.26Population Mean = 16.3
Actual Sampling Error = 16.26 - 16.3= -0.04.
Therefore, the actual sampling error is -0.04 ounces.
What is a typical sampling error? We use the formula below to compute the typical sampling error.
Typical Sampling Error = Standard Deviation / √(Sample Size)Standard deviation = 0.2 ounces
Sample size = 4 bags
Typical Sampling Error = 0.2/√4= 0.1/2= 0.05
Therefore, the typical sampling error is 0.05 ounces.

If 40% of a number is 120 and 55% of the same number is 165, find 15% of that
Number
Answers
If 40% of a number is 120 and 55% of the same number is 165 then 15% of that number is 45.
According to the question,
We have the following information:
40% of a number = 120
55% of the same number = 165
Now, let's take the number to be x.
So, we have the following expression:
40x/100 = 120
Using the cross multiplication method:
40x = 120*100
x = 120*100/40
x = 300
Now, we will find 15% of 300 by following the given steps:
15*300/100
15*3
45
Hence, if 40% of a number is 120 and 55% of the same number is 165 then 15% of that number is 45.

Answers
A discrete-time linear time-invariant filter can be analyzed by drawing the block diagram. The following cases are possible with their corresponding block diagram implementation of the system:
i. Direct form II
The Direct Form II block diagram implementation of the system is as follows:
The input signal enters the diagram from the left side. It is then divided by R before being passed through the delay element. The output of this delay element is then multiplied by the poles before being summed. The output of the zero is then added to the sum and the result is multiplied by R before being passed as the output signal.
ii. Transposed Direct Form II
The Transposed Direct Form II block diagram implementation of the system is as follows:
The input signal enters the diagram from the left side. It is then passed through the zero before being summed. The sum is then passed through the poles before being delayed by a single sample. The delayed output is then multiplied by R before being added to the output of the zero. The result is multiplied by R before being passed as the output signal.
iii. Cascade Form
The Cascade Form block diagram implementation of the system is as follows:
The input signal enters the diagram from the left side. It is then passed through the first zero before being delayed by a single sample. The delayed output is then passed through the second zero before being delayed again. The output of the second delay element is then passed through the first pole before being delayed by a single sample. The delayed output is then passed through the second pole. The result is multiplied by R before being passed as the output signal.

The geometric mean has a set up it must follow in order to "work". If you look at #3, x is a side of the smaller triangle that has a base of 3, but it's also a side of the large triangle that has a base of 3 + 8 which is 11. That means that x is your geometric mean. Setting up the geometric mean will look like this:
\(\frac{3}{x}=\frac{x}{11}\)
where x is the geometric means and the 3 and the 11 (the positions they are in) are the geometric extremes.
Now we cross multiply to solve for x:
\(x^2=33\) and
\(x=\sqrt{33}\)
That's the length of x in #3.
For #4, x is the side of the small triangle with the base of 7 and it's also the side of the large triangle with the base of 7 + 13 which 20. That means that x is the geometric mean. Setting up like above:
\(\frac{7}{x}=\frac{x}{20}\) and
\(x^2=140\) so
\(x=\sqrt{140}\)

Answers
The percentage of the players on the tennis team belongs to 8th graders from the given ratio is equal to 62.5%.
Ratio of the players of 7th graders to 8th graders on the tennis team = 3 : 5
Let the number of 7th graders on the tennis team be represented by 3x.
And let the number of 8th graders on the tennis team be represented by 5x.
Then,
The total number of players on the tennis team is 3x + 5x = 8x.
Percentage of players who are 8th graders,
= (the number of 8th graders (5x))/(the total number of players (8x)) × 100
Substitute the values we have,
⇒Percentage of players who are 8th graders = (5x / 8x) x 100%

Use the given graph to determine the limit, if it exists. (4 points)
A coordinate graph is shown with an upward sloped line crossing the y axis at the origin that ends at the open point 3, 1, a closed point at 3, 7, and a horizontal line starting at the open point 3, 3.
Find limit as x approaches three from the right of f of x. .
Answers
Explanation:
Refer to the graph below. It should be similar to what your teacher gave you, based off the description.
Since we're approaching 3 from the right side, this means we'll be working with the horizontal line portion. We could start at something like x = 3.2 and move closer to 3 by getting to x = 3.1 then x = 3.01 then x = 3.001 and so on. We never actually get to 3 itself.
As x gets closer to 3 from this direction, the y values are approaching 3 since every point on this horizontal line has the same y coordinate. Technically the y value is already at 3, but it's the same idea.
In terms of notation, we can write \(\displaystyle \lim_{x\to3^{+}}f(x) = 3\)
The portion \(x \to 3^{+}\) means we're approaching 3 from the positive side, aka the right hand side on the number line.

h(t) = (-0.0251)(1-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (in feet).
If he runs as well as his best race last year, will this hurdler clear the new height? Why or why not
Answers
Answer:
Something doesn't make sense. The time when his height is 0 is time t=0 and t=25.
The vertex would be halfway in between at time t=(0+25)/2 = 12.5 seconds.
But plugging that in, we get a height of:
3.90625 inches
I think you must have a typo... let's try this equation instead:

In a store, short shelves hold a items, and tall shelves hold b items. Braedyn notices that there are 21 short shelves and 9 tall shelves. How can the expression 21a + 9b help him find the total number of items on the shelves? Explain your reasoning. SOLUTION
Answers
The expression 21a + 9b provides a way for Braedyn to find the total number of items on the shelves by considering the individual quantities of items on the short and tall shelves separately and then combining them.
The expression 21a + 9b can help Braedyn find the total number of items on the shelves because it represents the sum of the number of items on the short shelves and the number of items on the tall shelves.
Let's break down the expression:
21a represents the number of items on the 21 short shelves.
Since each short shelf holds a items, multiplying the number of short shelves by a gives us the total number of items on the short shelves, which is 21a.
Similarly, 9b represents the number of items on the 9 tall shelves.
Each tall shelf holds b items, so multiplying the number of tall shelves by b gives us the total number of items on the tall shelves, which is 9b.
By adding the number of items on the short shelves (21a) and the number of items on the tall shelves (9b), we obtain the total number of items on all the shelves in the store.

Answers
The difference in length between the two bridges with the lengths of 12 m 60 cm and 18 m 63 cm is 6.03 meters.
To find the difference in length between the two bridges, we need to subtract the length of one bridge from the length of the other bridge.
Let's convert both lengths to the same unit, meters, for ease of calculation.
Length of the first bridge = 12 m 60 cm = 12.60 m
Length of the second bridge = 18 m 63 cm = 18.63 m
Now we can subtract the length of the first bridge from the length of the second bridge:
18.63 m - 12.60 m = 6.03 m
Therefore, the difference in length between the two bridges is 6.03 meters.
