Learning about the connections between finding the GCF of numbers, the distributive property, multiplying polynomials, and factoring has helped me understand how to simplify and solve for equations. The distributive property taught me about how to easily simplifying equations, since the requirement is to just distribute the given to the number(s). Factoring has taught me how to make an equation easier to solve. For example, when I'm given a problem that has very large numbers, I can see if they have a GCF and this will help me solve the problem in no time!
I enjoyed learning about this and I found this module easy! Thank you!

Question:
A party pack consists of x chocolate bars and x cans of drinks. Each chocolate bar costs $3 and each can of drink costs $1. The total cost for the chocolate bars and drinks in a party pack is more than $10. Find the minimum number of choclate bars in a party pack.
Btw, my teacher told me that the ans was 3. I'm kind of confused.
Answer:
3
Step-by-step explanation:
Your teacher is correct. The reason is because it is the total cost of both the chocolate and the can… if the choc is $3 and can is $1, you can have 3 chocolate bars because when you add the one can which is one dollar, it equals $10
3x3 = 9
9+1 = 10
Therefore 3 is the answer
Special right triangles please help!
Find the variable
Answer:
11. s = 14
12. k = 24
Step-by-step explanation:
There are two "special" right triangles that show up in trig and geometry problems.
The isosceles right triangle has angles of 45°-45°-90°, and side length ratios 1 : 1 : √2.
The half-equilateral triangle has angles of 30°-60°-90°, and side length ratios 1 : √3 : 2.
You will do yourself a favor if you remember and learn to recognize these triangles.
__
11.)The hypotenuse of the isosceles right triangle is 14√2. This tells you the basic ratio has been multiplied by 14. The side length is ...
s = 14
__
12.)The half-equilateral triangle has middle-length side 12√3. This means the basic ratio has been multiplied by 12. The triangle short side is 12, and the long side is twice that:
k = 24

A merchant bought a table for ₹8250 and spent ₹175 on its transportation. He
sold the table for ₹7500. Find its gain or loss?
Answer: Loss of 925
==============================================
Work Shown:
Total cost = 8250+175 = 8425
Total revenue = 7500
Profit = revenue - cost = 7500 - 8425 = -925
Profit = -925
The negative profit means the merchant lost money.
Answer: The merchant lost 575 dollars or whatever you call them.
Step-by-step explanation:
7500+175=7675
8250-7675= 575

Your job is to figure out how to make a "silver mile". Here in the United States we could do this with nickels, dimes, quarters, half-dollars, or silver dollars. I found on the United States Mint website that the Susan B. Anthony silver dollar was 1.04 inches in diameter. Making a mile using just this coin would be an easy calculation. We need a more interesting challenge. We are going to create a silver mile following a specific set of rules. You may need to cover a little more than the required distance since you cannot use fractional parts of the coins. Here are the rules:
1) Lay down enough Susan B. Anthony silver dollars to cover half of the mile.
2) Cover one-third of the remaining distance with half-dollars.
3) Use quarters to cover one-fourth of the remaining distance.
4) With dimes, cover one-fifth of the remaining distance,
5) Fill in the remaining distance with nickels.
What is the total value of the coins in this mile?
Please support this by showing evidence. Thanks a lot :)
The total value of coins to create a silver mile following the specific rules stated is $38,114.18
Distance left:63360 - 31650.48 = 31679.52 inches
A third of the distance is missing: 10559.84 inches
Diameter of the half-dollar: 1.205 inThis means 10,559.84 inches/ 1.205 in = 8763.35 rounded to 8764
Total distance coverd 8,764 x 1.205 in = 10560.61
Total distance left: 31679.52 - 10560.61 = 21118,91 / 4 = 5279.72
Diameter of quarters: 0.750 inchesThis means 5279.72 / 0.750 =7039.62 rounded to 7040
7040 x 0.750 = 5280
Total distance left = 21118,91 - 5280 = 15,838.91 / 5 = 3167.782
Diameter of dimes: 0.705This means 3167.82 / 0.705 = 4493.36 rounded to 4494
0.705 x 4494 = 3168.27
Total distance left = 15,838.91 - 3168.27 = 12670.64
Diameter of the nickel: 0.835This means 12670.64/ 0.835 = 15174.41 rounded to 15175
How much money was used?For this change the coins to dollars:
Susan B. Antony Silver dollars: 30462 = $30462
Half-dollars: 8764 = $4382
Quarters: 7040 = $1760
Dimes: 4494 = $561.75
Nickels: 15175 = $948.43
Total: $38114,18

The sides of a triangle are 20, 51, and 50. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse. The triangle is because the square of the largest side the sum of the squares of the other two sides.
Answer: Obtuse Triangle
Step-by-step explanation:
It is not right, because a^2 + b^2 doesn’t equal c^2. It is Actually obtuse because a^2 + b^2 is greater than c^2 because 20^2+50^2 =2900 which is greater than 2601 or 51^2.
Which of the following z-values, standard deviations, and sample sizes produce a margin of error of 0.95? m e = startfraction z times s over startroot n endroot endfraction z = 2.14; s = 4; n = 9 z = 2.14; s = 4; n = 81 z = 2.14; s = 16; n = 9 z = 2.14; s = 16; n = 81
The z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is z = 2.14; s = 4; n = 81.
What is the margin of error?The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The formula of the margin of error is given by the formula,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
A.) z = 2.14; s = 4; n = 9
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{4}{\sqrt{9}}\\\\\\MOE =2.85[/tex]
B.) z = 2.14; s = 4; n = 81
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{4}{\sqrt{81}}\\\\\\MOE =0.9511[/tex]
C.) z = 2.14; s = 16; n = 9
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{16}{\sqrt{9}}\\\\\\MOE =11.413[/tex]
D.) z = 2.14; s = 16; n = 81
The margin of error is,
[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]MOE = 2.14\times \dfrac{16}{\sqrt{81}}\\\\\\MOE =3.80[/tex]
hence, the z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is z = 2.14; s = 4; n = 81.

A popular video game claims that the average time needed to reach level 10 paladin is 3 hours with a standard deviation of 0.4 hours. james thinks that he and his four friends are more skilled than the average gamer because it took them an average of only 2.5 hours. which of the following is the most restrictive level that would validate his claim? upper-tail values a 5% 2.5% 1% critical z-values 1.65 1.96 2.58 1% 2.5% 5% 10%
The probability that the claim of James is correct is 1%.
What is a standard error?The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is its standard error. The standard error of the mean is the term used when the statistic is the sample mean.
In order to know if the claim of James is correct or not, firstly we need to determine the standard error. The standard error is the ratio of the standard deviation and the square root of the sample. Therefore, the standard error can be written as,
[tex]\rm Standard\ Error, SE =\dfrac{\sigma}{\sqrt n} = \dfrac{0.4}{\sqrt5} =0.178[/tex]
Thus, the standard error is 0.178.
Further, The z-score is defined as the distance from the sample to the population mean in units of standard error. Therefore, the z-score can be written as,
[tex]z = \dfrac{X-\mu}{SE}=\dfrac{(3- 2.5)}{0.178} = 2.81[/tex]
Using the Z-table in order to know the probability of the claim of James is correct or not, therefore, at this z-score, the probability is 0.9974≈1.00%.
Hence, the probability that the claim of James is correct is 1%.
