Answer:
1.The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
2.The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.
3.There are no outliers. Explanation: An observation is an outlier if it falls more than above the upper quartile or more than below the lower quartile.
4.20. The "average" you're talking about is actually called the "mean". It's not exactly answering your question, but a different statistic which is not affected by outliers is the median, that is, the middle number. {90,89,92,91,5} mean: 73.4 {90,89,92,91,5} median: 90.

Use the drop down to answer the question about converting to a fraction.How many repeating digits are in ?What value is multiplied on both sides of the equals sign?What fraction represents ?
The decimal is a repeating decimal, and the actual fraction represented by 0.64⁻ is 64/99
The number of repeating digitsThe decimal number is given as:
0.64⁻
There are two numbers after the decimal point
So, the number of repeating digits is 2
The value multiplied on both sides of the equals signIn (a), we have the number of repeating digits to be 2.
So, the value multiplied on both sides is:
Value = 10²
Value = 100
Hence, the value multiplied on both sides of the equals sign is 100
The actual fractionThe number is the decimal points is 64.
And the value multiplied on both sides of the equals sign is 100.
So, the fraction is:
64/(100 - 1)
This gives
64/99
Hence, the actual fraction represented by 0.64⁻ is 64/99

Step-by-step explanation:
Un arquitecto ha pagado en un corralón un total de $ 130 por 20 Ladrillos, 5 kg de Arena y 10 kg de Cemento. Calcular el precio de cada articulo, sabiendo que 1 kg de Cemento cuesta el triple que 1 Ladrillo y que 1 kg de Arena cuesta igual que 4 kg de Cemento más 4 Ladrillos. Siendo: número de ladrillos y: kg de arena kg de cemento
Answer:
1 ladrillo cuesta 1 dólar. 1 brick costs 1 dollars.
1 kg de cemento cuesta 3 dólares: 1 kg cement costs 3 dollars
1 kg de arena cuesta $ 16: 1 kg sand costs $ 16
Step-by-step explanation:
Spanish
Deje que los ladrillos, la arena y el cemento se denoten por b, sy c. Luego, de acuerdo con la condición dada
20b + 5s + 10c = $ 130 --- ecuación 1
1c = 3b ------ ecuación 2
1s = 4c + 4b ------ ecuación 3
Poniendo la ecuación 2 en la ecuación 3
1s = 4 (3b) + 4b
1s = 16b ---------- ecuación 4
20b + 5s + 10 (3b) = $ 130
50b + 5s = 130 --- ecuación 5
Poniendo la ecuación 4 en la ecuación 5
50 b + 5 (16b) = 130
50 b + 80b = 130
130 b = 130
b = 130/130 = $ 1 ------- ecuación a
1 ladrillo cuesta 1 dólar.
Poner el valor de costo de 1 ladrillo en estas ecuaciones
1c = 3b ------ ecuación 2
1s = 4c + 4b ------ ecuación 3
1c = 3 (1) = $ 3 -------- ecuación b
1 kg de cemento cuesta 3 dólares
1s = 4c + 4b
1 s = 4 (3) + 4 (1)
1 s = 12 + 4
1s = $ 16 ------ ecuación c
1 kg de arena cuesta $ 16
Poner valores de la ecuación a, b, c en la ecuación 1
20b + 5s + 10c = $ 130
20 (1) + 5 (16) + 10 (3) = 130
20 + 80 + 30 = 130
130 = 130 ------------ por lo tanto probado
English
Let the bricks , sand and cement be denoted by b, s and c. Then according to the given condition
20b+ 5s+ 10c= $130--- equation 1
1c= 3b------ equation 2
1s= 4c+4b------ equation 3
Putting equation 2 in equation 3
1s= 4(3b) + 4b
1s= 16b---------- equation 4
20b+ 5s+ 10(3b)= $130
50b + 5s= 130--- equation 5
Putting equation 4 in equation 5
50 b + 5 (16b) = 130
50 b+ 80b= 130
130 b= 130
b= 130/130= $1------- equation a
1 brick costs 1 dollars.
Putting the cost value of 1 brick in these equations
1c= 3b------ equation 2
1s= 4c+4b------ equation 3
1c= 3(1)= $3-------- equation b
1 kg cement costs 3 dollars
1s= 4c+4b
1s= 4(3) + 4(1)
1s= 12+4
1s= $16 ------ equation c
1 kg sand costs $ 16
Putting values from equation a, b, c in equation 1
20b+ 5s+ 10c= $130
20 (1) + 5 (16) + 10 (3)= 130
20 + 80 + 30 = 130
130 = 130 ------------ hence proved

If each serving of the stew will contain 1 4 14 pound of meat, how many servings of the stew can the club make? Enter your answer in the box.
Complete question :
The line plot shows the weights of packages of meat that members of a club bought. The meat will be mixed with vegetables to make stew for a club dinner. Each serving of the stew contains 1/4 pound of meat. How many servings of the stew can the club make?
Answer:
36 servings
Step-by-step explanation:
From the plot ; we take the sum of total weight of meat packages :
(5/8 * 2) + 6/8 + 1 + (9/8 * 3) + 10/8 + 11/8
10/8 + 6/8 + 8/8 + 27/8 + 10/8 + 11/8 = 72 / 8 = 9 meat packages
Each serving of meat = 1/4
Number of servings the club can make :
Total meat package / pound of meat per serving
(9 ÷ 1/4)
9 * 4/1
= 36 servings
Answer:
36 hope this help

Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 10 men was 35 minutes per day. The standard deviation was 10 minutes per day. The mean listening time for a sample of 12 women was also 35 minutes, but the standard deviation of the sample was 12 minutes. At the 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women

Step-by-step explanation:
Given ;
s2 = 10 ; n2 = 10 ; s1 = 12 ; n1 = 12
Hypothesis :
H0 : σ1² = σ2²
H1 : σ1² ≠ σ2²
The test statistic :
Ftest = s1² / s2² = 12² / 10² = 144 / 100 = 1.44
The Pvalue using the Pvalue from Ftest calculator :
Numerator df = 12 - 1 = 11
Denominator df = 10 - 1 = 9
Pvalue = 0.2969
At α = 0.1
If Pvalue > α ; Fail to reject H0
0.2969 > 0.1 ; Hence, we fail to reject the Null
Hence, we cannot conclude that variation exists

5. the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution
Step-by-step explanation:
5. 8 = -4(-2) => 8 = 8 (true)
8 = 1/2(-2) + 7 => 8 ≠ 6 (false)
the given ordered pair is not a solution
6. 3 + 5(1) = 8 => 8 = 8 (true)
4(3) - 5(1) = 7 => 7 = 7 (true)
the given ordered pair is a solution
7. -5 = 4 - 9 => -5 = -5 (true)
4 + (-5) = -1 => -1 = -1 (true)
the given ordered pair is a solution
Give coordinates for any three points that are on the same vertical line. Include at least one point that has a mixed number as a coordinate. (Can the numbers be made up? I put in (1 1/2,4), (2,4), (5,4) as the answer. Is that correct?)
Answer: No
Step-by-step explanation:
Points inserted are
[tex](1\ \frac{1}{2},4), (2,4), (5,4)\\[/tex]
As all the points have the same y-coordinate, therefore, they must lie on the same horizontal line of [tex]y=4[/tex]
So, the ingested points are not correct.
Points maybe [tex](1,2), (1, 3), (1,3\ \frac{1}{2})[/tex] as they line on the same vertical line.
