Answer:
In Data Set A mean , standard deviation are better measure of center as they give more information about the center of data.
In Data Set B mean , standard deviation are better measure of center as they give more information about thecenter of data.

Mean of Set A= 1+3+3+2+4+0+4+3+3+5+2/ 11= 30/11= 2.7272
Median of Set A= 0,1,2,2,3,3 ,3,3,4,4,5
Median ( the middle value)=3
Mode( the repeated value)= 3
Quartiles
1st Quartile= n/4 value= 30/4= 7.5 which lies between 4th and 5th value
3rd quartile= 3n/4= 90/4= 22.5 which lies between 10 th and 11th value
Range= highest value- lowest value= 5-0=5
Standard Deviation = 1.354
In this mean ,median, mode and standard deviation are better measure of center as they give more information about the data.
The range and quartiles are better measure of spread.
Mean of Set B= 3+5+5+4+6+1+6+6+6+6+5/11=53/11=4.81818
Median of Set B= 1,3,4,5,5,5,6,6,6,6,6
Median ( the middle value)= 5
Mode ( the repeated value)= 6
Quartiles
1st Quartile= n/4 value= 53/4= 13.25 which lies between 4th and 5th value
3rd quartile= 3n/4= 159/4= 39.75 which lies between 9 th and 10 th value
Range= highest value- lowest value=6-1= 5
Standard Deviation= 1.5266
In this mean , standard deviation are better measure of center as they give more information about the data.
The median mode quartiles and range are better measure of spread.
A smaller standard deviation indicates that most of the observations are close to the mean while a large value implies that the observations are scattered widely about the mean.
The quartiles must be having values near 25% and 75% of the data.
The center gives a value which is located around the center
Mean: It gives the average value.
Median:It is the middle value when data is ordered from least to greatest.
The spread gives the value showing where the data may variate.
Range: Total spread is given by the range.
Standard deviation: How far a data point is from the mean.

find the value of x and of the measure of the angle labeled 3x
Answers
Answer:
x is 9; angle measure is 27
Step-by-step explanation:
Rules used:
Angles on a straight line add up to 180.
Angles at a point add up to 360.
180 - 27 = 153
That is the magnitude for the angle between the 3x and 27.
180 - (45 + 27) = 108
That is the magnitude of the angle between 27 and 45.
360 - (153 + 27 + 108 + 45)
= 360 - 333
= 27
3x = 27
x = 9
The following table shows the values of y for different values of x:

Step-by-step explanation:
Hello There!
The figure shown is a composite figure ( so we can't find the area of it using one formula )
That being said we want to break the irregular figure into regular figures in which the area can simply be found using a formula
The figure would be broken in to the following shapes
A rectangle with a width of 4 ft and a length of 9 ft
A rectangle with a width of 8 ft and a length of 9 ft
A triangle with a height of 5 ft and a base of 9 ft
Now that we have broken the irregular figure into regular shapes we want to find the area of each individual shape
For the smaller rectangle:
The area of a rectangle can simply be calculated by multiplying the width and length
So A = 9 * 4
9 * 4 = 36
so the area of the smaller rectangle is 36ft²
For the larger rectangle
Once again the area can simply be found by multiplying the width and length
A = 8 * 9
8 * 9 = 72
so the area of the larger rectangle is 72ft²
For the triangle
To find the area of a triangle we want to use this formula
[tex]A = \frac{bh}{2}[/tex]
where b = base and h = height
We have already identified the base and height so all we have to do is plug in the values into the formula
[tex]A=\frac{5*9}{2} \\5*9=45\\\frac{45}{2} =22.5[/tex]
so the area of the triangle is 22.5ft²
Finally we add the areas of each regular figure
22.5 + 72 + 36 = 130.5
so we can conclude that the area of the composite figure is 130.5ft²
Dorothy opens a savings account with $80 that earns 8.5% interest
per year, not compounded.
How much money, to the nearest penny, will Dorothy have in 1 year?
Give your answer in dollars.
Answers
Answer:
$86.8
Step-by-step explanation:
Given that,
Principal, P = $80
Rate of interest, R = 8.5%
We need to find the money he will have in 1 year. As the interest is not compounded, it must be simple interest. The simple interest can be calculated by the formula,
[tex]I=\dfrac{PRT}{100}\\\\I=\dfrac{80\times 8.5\times 1}{100}\\\\=\$ 6.8[/tex]
We know that,
Amount = Principal + interest
= $80 + $6.8
= $86.8
Hence, the amount will become $86.8.

Jarred went to the bookstore,
He bought a softcover book which was on sale for 10%
off. He spent $18 on the book, What was the original
price?
Answers
Answer:
the original price of the book is $20
Step-by-step explanation:
sometimes in a question, they put things in the question that don't actually help us get to the answer. usually we ignore it, but i'm going to list them out just to help you a bit more.
Things that are useless:
his name is Jarred (his name could be gary, it doesn't affect us getting the answer)he went to a bookstore (he could've gone to the library, it wont affect us getting to the answer)the book is softcover (it could be any type of book, wont affect us getting to the answer)the item is a book (it could be anything that he bought, wont affect us getting to the answer.)Things that are helpful:
the book was on sale (helps us know that the price was reduced)the book was on sale 10% (helps us know how much it was reduced by)he spent $18 for the reduced price (helps us know how much he spent)Ok, now that we know those, let's work on the question.
let b be the original book price
we need to find 10% so we have to use 90% (because 100 - 10 = 90)
if we needed to find 20% we would use 80% (because 100 - 20 = 80)
and so on.
90% of b = 18 (90% of the og. book price equals 18)
90/100 × b = 18 (write a correct equation and make the percent a fraction)
9/10 × b = 18 (simplify both sides of the equation)
9 × b = 180 (multiply both sides of the equation to get rid of fraction)
b = 20 (divide both sides of the equ. to get b by itself)
the original price of the book is $20

(a) The mean of C is 1.0 and the standard deviation is 1.0.
(b) The mean of the total number of adult and child tickets purchased is 3.0, and the standard deviation is approximately 1.56.
(c) The mean amount spent per purchase is $65, and the standard deviation is approximately $33.54.
(a) To compute the mean of C, we multiply each value of C by its corresponding probability and sum them up:
Mean (μ) = (0 * 0.4) + (1 * 0.3) + (2 * 0.2) + (3 * 0.1) = 0 + 0.3 + 0.4 + 0.3 = 1.0
To compute the standard deviation, we first need to calculate the variance. The variance (σ²) is found by summing the squares of the differences between each value of C and the mean, weighted by their corresponding probabilities:
Variance (σ²) = [(0 - 1)² * 0.4] + [(1 - 1)² * 0.3] + [(2 - 1)² * 0.2] + [(3 - 1)² * 0.1] = 0.4 + 0 + 0.2 + 0.4 = 1.0
Finally, we take the square root of the variance to obtain the standard deviation (σ):
Standard Deviation (σ) = √(1.0) = 1.0
(b) Since the numbers of child tickets and adult tickets purchased are independent, the mean of the total number of adult and child tickets purchased is the sum of their individual means:
Mean (μ) = Mean of child tickets (μ c) + Mean of adult tickets (μ a) = 1.0 + 2 = 3.0
The variance of the total number of tickets purchased is the sum of the variances of the child and adult tickets:
Variance (σ²) = Variance of child tickets (σ c²) + Variance of adult tickets (σ a²) = 1.0 + (1.2)² = 2.44
The standard deviation of the total number of tickets purchased is the square root of the variance:
Standard Deviation (σ) = √(2.44) ≈ 1.56
(c) To compute the mean and standard deviation of the total amount spent per purchase, we need to multiply the number of child tickets and adult tickets purchased by their respective prices and sum them up.
Mean (μ) = Mean number of child tickets (μ c) * Price of child ticket + Mean number of adult tickets (μ a) * Price of adult ticket
Mean (μ) = 1.0 * $15 + 2 * $25 = $15 + $50 = $65
Variance (σ²) = Variance of child tickets (σ c²) * (Price of child ticket)² + Variance of adult tickets (σ a²) * (Price of adult ticket)²
Variance (σ²) = 1.0 * ($15)² + (1.2)² * ($25)² = $225 + $900 = $1125
Standard Deviation (σ) = √(1125) ≈ $33.54
Therefore, the mean amount spent per purchase is $65, and the standard deviation is approximately $33.54.

An isosceles triangle has two identical angles.
The three angles need to add up to 180 degrees.
If one angle is 100 then the other two angles added together need to equal 180-100 =‘80 degrees.
Since two angles need to be the same the other angles are 80 / 2 = 40 degrees each.
The answer is 40
Answer:
A. first answer on the left.
Step-by-step explanation:
If one of the angles is 100 then if the triangle is isosceles then the two remaining angles have to be either 100 and - 20 (which is impossible because at this level of math there is no such thing as an angle with a measure of - 20).
The minus 20 comes from every triangle having 180 degrees. 100 + 100 adds to 200, which means the third angle has to be the impossible measure of - 20.
The other possibility is that the given angle of 100 is the top angle and that leaves 80 degrees for the two isosceles angles.
2x = 80
x = 80/2
x = 40
The only possible answer is 40 - 40 - 100
