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 teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below. Studied: Did Not Study: Part 1: Calculate the mean of the group that studied, rounded to the nearest tenth. Part 2: Calculate the mean absolute deviation of the group that studied, rounded to the nearest tenth. Part 3: How many of the scores (from the group that studied) are within one mean absolute deviation of the mean.
The evaluation of the figures needed for the considered survey are:
The mean of the considered data is 1667/18 ≈ 92.61The mean of these 18 absolute deviations comes out as [tex]91.8/18 \approx 5.1[/tex]The number of scores which are within one mean absolute deviation of the mean is 10Suppose the data specified is of n sized as [tex]x_1, x_2, \cdots , x_n[/tex]
Let this data's mean be [tex]\bar{x}[/tex]
Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.
It is calculated as:
[tex]M.A.D = \dfrac{\sum_{i=1}^n|x_i-\bar{x}|}{n}[/tex]
The data is missing from the problem statement, and is as shown below:
Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89Calculating the needed figures part by part:
Part 1: Mean of the group that studied, rounded to the nearest tenth.
Mean is the sum of observations divided by number of observations.
The sum of 18 observations: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84
is 1667. Thus, its mean is 1667/18 ≈ 92.61 ≈ [tex]\bar{x}[/tex]
Part 2: The mean absolute deviation of the group that studied:
The absolute deviations of 18 observations: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84
from the mean [tex]\bar{x}[/tex] ≈ 92.61 are approx:
[tex]|92.61 - 88| = 4.6\\|92.61 - 100| = 7.4\\|92.61 - 94| = 1.4\\|92.61 - 79| = 13.6\\|92.61 - 92| = 0.6\\|92.61 - 100| = 7.4\\|92.61 - 95| = 2.4\\|92.61 - 83| = 9.6\\|92.61 - 89| = 3.6\\|92.61 - 99| = 6.4\\|92.61 - 100| = 7.4\\|92.61 - 91| = 1.6\\|92.61 - 89| = 3.6\\|92.61 - 95| = 2.4\\|92.61 - 100| = 7.4\\|92.61 - 93| = 0.4\\|92.61 - 96| = 3.4\\|92.61 - 84| = 8.6\\[/tex]
Their sum is 91.8 approx.
Thus, the mean of these 18 absolute deviations comes out as
[tex]91.8/18 \approx 5.1[/tex]
Part 3: The number of scores which are within one mean absolute deviation of the mean
The range within one absolute deviation of the mean is [tex][92.61 - m.a.d, 92.61 + m.a.d] = [92.61 - 5.1, 92.61 + 5.1] = [87.51, 97.71][/tex]

A line passes through $A(1,1)$ and $B(100,1000)$. How many other points with integer coordinates are on the line and strictly between $A$ and $B$
Answer:
8
Step-by-step explanation:
Integers are whole numbers or opposite of whole numbers.
The slope is 111/11.
How?
Change of y is 1000-1=999.
Change of x is 100-1=99.
The slope is 999/99=111/11.
So if we start at (1,1) and we rise 111 and run 11 right, we get (12,112).
*Rise effects y and run effects x.
If we do that again from (12,112) we get (23,223).
Following the pattern of going up 111 and right 11 from each new location discovered we get all the of these points:
Start (1,1)
(12,112)
(23,223)
(34,334)
(45,445)
(56,556)
(67, 667)
(78, 778)
(89, 889)
(100, 1000) which is the end.
So we just need to count tthe points between begin point and end point which is 8 points.

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
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%.

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

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
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
