Suppose you are designing and conducting a poll to see which of the Congressional candidates are popular in your area. Use the terminology and concepts that we are learning in Lesson 1 - population, sample, sampling methods, representative sample, and presentation of data....
1. Discuss the following in your own words :
the population that you are trying to predict,
where and how are you selecting your sample,
what sampling method would you use,
how would you assure that you are selecting a representative sample, and
show an example of how you would present your data.
The population we're trying to predict is the population that is going to be Voters in our area, the where should probably be well as above our area, and the how now, generally speaking, we want to do a simple, random, or a random sample of some sort, random sample.
For instance, what you could do would be something like choose: random addresses in the area and send a survey, but sending a survey could introduce self-selection bias. So it would be ideal to visit in person basically and ask a few questions making sure the representative sample or how to ensure that we're getting a representative sample would be to, for instance, filter the random results and make sure that we have an even distance.
Ensure that there's an equal number within each quadrant of the town, basically split up the town. Split towns into regions of populations or population densities and make sure we get the same proportion from each region. However, we end up splitting the town into different regions. We show the proportion or show who is the most popular candidate in each 1 of the regions, so it could be something like this. That was supposed to be an alternative to a bar graph. The number of results for each different candidate depends on whether or not there's a sort of well-defined districts or areas in the town, but most sorts of relatively large cities have things like that. So the idea would be to represent not just the location, but also the information that you gain separately.

Split up the town so that there are an equal amount in each of its four quadrants. Make sure we receive the same proportion from each region by dividing towns into population or population density regions. But ultimately, we divide the town into many parts. It might look something like this since we display the percentage or the candidate who is most supported in each location. That was meant to be a bar graph substitute. Whether or not a town has clearly defined districts or areas affects the amount of results for each candidate, although this is true of most types of moderately large cities.

christopher is working two summer jobs, making $7 per hour babysitting and making $10 per hour washing cars. in a given week, he can work no more than 16 total hours and must earn a minimum of $130. if xx represents the number of hours babysitting and yy represents the number of hours washing cars, write and solve a system of inequalities graphically and determine one possible solution.
Christopher can work average 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.
Christopher is working two summer jobs and has a maximum of 16 hours to work in a given week. He is making $7 per hour babysitting and $10 per hour washing cars. To meet the minimum wage requirement of $130, he needs to make a total of $130 in a week. We can represent this using a system of inequalities. The first inequality is 7xx + 10yy ≥ 130, which means that the total wages (7 times the hours babysitting plus 10 times the hours washing cars) must be greater than or equal to $130. The second inequality is xx + yy ≤ 16, which means that the total hours (babysitting plus washing cars) must be less than or equal to 16. Graphically, we can solve this system of inequalities to find the possible solutions. One possible solution is x = 9 and y = 7, meaning Christopher can work 9 hours babysitting and 7 hours washing cars in a given week to meet the minimum wage requirement and not exceed the maximum hours he can work.
Graphically:
7xx + 10yy ≥ 130
xx + yy ≤ 16
7xx + 10yy = 130
xx + yy = 16
Therefore, the solution is x = 9 and y = 7.

Empirical Rule 06
IQ scores can be described using a Normal distribution with a mean of 100 and a standard deviation of 15.
Using the Empirical '68-95-99.7' Rule, what percent of IQ scores are above 130?
Answer:
The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, 95% lies within two standard deviations, and 99.7% lies within three standard deviations.
In this case, the mean is 100 and the standard deviation is 15, so approximately 95% of the data lies within two standard deviations of the mean. Since two standard deviations of 100 is 30 (15 * 2), this means that approximately 95% of the data lies within the range of 70 to 130. Therefore, approximately 5% of the data lies outside of this range, with 2.5% lying below 70 and 2.5% lying above 130.
Therefore, the percent of IQ scores that are above 130 is approximately 2.5%.

2. A local manufacturing firm produces four different metal products, each of which must be machined, polished and assembled. the specific times requirements ( in hours) for each products are as follows
Machining hours Polishing hours Assembling hours
Product I 3 1 2
Product II 2 1 1
Product III 2 2 2
Pruduct IV 4 3 1
Step-by-step explanation:
To find the total time required to produce each product, we can add up the machining, polishing, and assembling hours for each product. For example, for Product I, the total time required would be:
Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours
We can do this for each product to find the total time required for all four products:
Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours
Total time for Product II = 2 hours + 1 hour + 1 hour = 4 hours
Total time for Product III = 2 hours + 2 hours + 2 hours = 6 hours
Total time for Product IV = 4 hours + 3 hours + 1 hour = 8 hours
So, the total time required to produce all four products is 6 hours + 4 hours + 6 hours + 8 hours = 24 hours.

Answer:
In an arithmetic sequence, each term is obtained by adding the common difference to the previous term. In this case, the common difference is 3, so the formula for the nth term of the sequence can be written as:
a^n = a^1 + (n-1) * d
where a^1 is the first term of the sequence, and d is the common difference.
Since the first term of the sequence is -25 and the common difference is 3, we can plug these values into the formula to find the 30th term of the sequence:
a^30 = (-25) + (30-1) * 3
= (-25) + 29 * 3
= (-25) + 87
= 62
Therefore, the 30th term of the sequence is 62.

1/a+1/b=1/c, what is the average (arithmetic mean) of a and b?
The arithmetic mean of a and b in the expression 1/a + 1/b = 1/c is 2c.
What is the arithmetic mean or average?Arithmetic mean or average can be obtained by adding all the given values and then dividing the total sum by the number of values.
Given, An expression of the form 1/a + 1/b = 1/c.
We know average of two numbers is sum of those numbers divided by 2.
So, {(1/a) + (a/b)}/2 = 1/c.
Now to keep the equality we also have to divide the RHS by 2.
Therefore, {(1/a) + (a/b)}/2 = (1/c)/2.
{(1/a) + (a/b)}/2 = (1/c)×((1/2).
{(1/a) + (a/b)}/2 = 1/2c.
So, The arithmetic mean of 1/a + 1/b is 1/2c.
Now taking the reciprocal of 1/a and 1/b which is a and b the arithmetic mean is

Find the degree measure of each angle in the triangle.
Answer:
∠N° = 19°
∠M° = 35°
∠L° = 126°
Step-by-step explanation:
Total angle in a triangle: 180°
∠N° = x°
∠M° = ( 2x - 3 )°
∠L° = ( 7x - 7 )°
180 = N + M + L
180 = x + 2x - 3 + 7x - 7
180 = 10x - 10
10x = 180 + 10
10x = 190
Divide both side by 10
x = 19
∠N° = x° = 19°
∠M° = ( 2x - 3 )° = ( 2(19) - 3 )° = 35°
∠L° = ( 7x - 7 )° = ( 7(19) - 7 )° = 126°

You want to find the dimensions, perimeter, and area of a foundation such that the length is 6 feet more than twice the width, and the area is 1046 more that the value of the perimeter.
SetupWe can let x and y represent the length and width, respectively. Then the given relations translate to the equation ...
A = LW . . . . . . . area formula
P = 2(L +W) . . . . perimeter formula
y = 2x +6 . . . . . relation between dimensions
xy = 2(x +y) +1046 . . . . . relation between perimeter and area
SolutionUsing the first equation to substitute for y, we have ...
x(2x +6) = 2(x +(2x +6)) +1046
2x² +6x = 6x +1058 . . . . . . . . . . . . eliminate parentheses
x² = 529 . . . . . . . . . . . . . subtract 6x and divide by 2
x = √529 = 23 . . . . . . . . . width; matches B
y = 2(23) +6 = 52 . . . . length
area = (23)(52) = 1196 . . . area; matches A
perimeter = 2(23 +52) = 2(75) = 150 . . . . matches C
The area is 1196 square feet. (A)
The width is 23 feet. (B)
The perimeter is 150 feet. (C)

Emilio buys liter bottles of shampoo when the store has the promotion shown. Write an expression in two different ways to represent the total cost 0f 3 liters of shampoo. Let L be the regular price of a liter bottle.
The expressions for the total costs are 2L + 0.7L and 2.7L
How to determine the expression for the total cost?From the question, we have the following parameters that can be used in our computation:
Number of litres = 3
Regular price = L
Discount = 30%
This means that there is a discount on the third item
So, we have the following expression
Total amount = 2 * L + L * (1 - discount)
Substitute the known values in the above equation, so, we have the following representation
Total amount = 2 * L + L * (1 - 30%)
Total amount = 2 * L + L * 0.7
This gives
Total amount = 2L + 0.7L
Evaluate the sum
Total amount = 2.7L
Hence, the expression is 2.7L

The expression for the total cost of 3 liters of shampoo is written as
2.7 L2L + 7L/10How to write the expressionLet L be the regular price of a liter bottle
The expression is written in decimal and in fraction
For the promotion buy 2 liters get 30% of 3rd liter
30% off = 0.3 off
= (1 - 0.3)
= 0.7
The total cost will be
= 2 * L + 0.7 * L
= 2L + 0.7L
= 2.7 L
The cost of three bottles of shampoo is 2.7L
In another way
= 2L + (1 - 0.3)L
= 2L + 0.7L

The total monthly rent for these three stores is $8,786.25.
What is total ?
Total refers to an entire or complete amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.
The outcome of adding two or more numbers or phrases is known as the sum in mathematics. The sum is a method of bringing things together as a result. To put it another way, adding two or more numbers together results in a new result or total.
The monthly cost for a square foot of rental space in each city is as follows:
Place Monthly Cost for a Square Foot
Los Angeles $5.75
San Francisco $6.95
Seattle $4.25
It is also provided that the store in Los Angeles will be 580 square feet, the store in San Francisco will be 500 square feet, and the store in Seattle will be 465 square feet.
Compute the total monthly rent for these three stores as follows:
Total Monthly Rent = Monthly Cost for a Square Foot × Area
= (5.75 * 580) +(6.95 * 500) +(4.25 * 465)
= 3335 + 3475 + 1976.25
= 8786.25
Thus, the total monthly rent for these three stores is $8,786.25.
