Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get

which expression is equivalent to -4/7 - 8/9 + 4/7 - 9/8
Answer:
I misunderstood the question before, but here are two expressions equivalent to -4/7 - 8/9 + 4/7 - 9/8.
71/72 + 70/72 +4/72
-1/7 - 3/7 - 5/9 - 3/9 + 2/7 +2/7 - 4/8 - 5/8
Solved: -2 1/72
Step-by-step explanation:
I could simply take the answer you get when combining all of the fractions, and I can make a new expression out of it. For example, I could use: 71/72+ 70/72+4/72. Or I could break apart all of the original fractions into smaller fractions. Example: -1/7 - 3/7 - 5/9 - 3/9 + 2/7 +2/7 - 4/8 - 5/8.
To solve: Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16

Luis wants to buy a skateboard that usually sells for $79.85. All merchandise is discounted by 12%. What is the total cost of the skateboard if Luis has to pay a state sales tax of 7.25%? Round your intermediate calculations and answer to the nearest cent.
this is how it solved now use this to solve the next question pls if it is right I will mark you brainliest it is obviously wrong that I don't have to think about it then I will report you
Analyze Information
The skateboard costs $79.85.
The discount is 12%, or 0.12.
The sales tax is 7.25%, or 0.0725.
Formulate a Plan
Calculate the discount and subtract it from the original total. Calculate the sales tax and add it to the discounted price.
Solve
Discount: 0.12 × $79.85 ≈ $9.58
Skateboard − Discount = Sale Price
$79.85 − $9.58 = $70.27
Sales tax: 0.0725 × $70.27 ≈ $5.09
Sale Price + Sales Tax = Final Price
$70.27 + $5.09 = $75.36
The total cost of the skateboard is $75.36.

Luis wants to buy a skateboard that usually sells for $79.26. All merchandise is discounted by 12%. What is the total cost of the skateboard if Luis has to pay a state sales tax of 6.25%? Round your intermediate calculations and answer to the nearest cent.
The total cost of the skateboard is $_____?
Answer:
Luis wants to buy a skateboard that usually sells for $79.99
all merchandise is discounted by 12% = 0.12
Discount amount = sale price * discount percentage
= 79.99 * 0.12 = 9.5988
Selling price after discount = 79.99 - 9.5988 = 70.3912
Now we apply sales tax for the price after discount
sales tax of 6.75 % = 0.0675
Tax amount = price after discount * tax percentage
= 70.3912 * 0.0675= 4.751406
the total cost of the skateboard = Price after discount + tax amount
=70.3912 + 4.751406 = 75.142606
$75.14 is the total cost of the skateboard

Answer: $77:51
Step-by-step explanation:79.85-12%=70.26

At the store you want to buy a bunch of 3d printed Christmas gifts for your family. Each large tree costs $4.50 , and each small tree costs $2.25, If you buy 4 large trees, and can spend a total of $50. Write and solve an inequality for number of small trees (s) you can buy
We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.
If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.
The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.
To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:
s * $2.25 = $32
s = $32 / $2.25
s = 14.22
Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.
Answer:
If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

A researcher asked five of his doctor friends if they thought the new Brand X medicine that he
developed was effective. Four responded "yes." The researcher used the results to write a TV
advertisement claiming that "4 out of 5 doctors prefer Brand X medicine." Is this a valid inference?
Explain.
Use pencil and paper. Explain all of the factors that are necessary for an inference to be valid.
Is the inference valid? Explain. Choose the correct answer below.
OA. No, because the doctors asked are not a representative sample of the population of doctors.
OB. No, because 4 doctors said yes out of 9 who were asked.
OC. Yes, because 4 doctors said yes out of 5 who were asked.
OD. Yes, because the doctors asked are a representative sample of the population of doctors.
Answer:
OA
Step-by-step explanation:
First of all, this is not math its common sense
4/5 is just an ifference. in order to prove this, the general term would be asking a factor of the doctors such as 10, and then ask.
To prove this , use algebra.
4x/5x
Shorten to 1
0.8x/1x
So you would theoretically be getting infinite amounts of doctors. but still 4/5 of them will say yes.
This is false because N0 is a cardinal number system where is omega is a ordinal.
asking five people is indefinitely not enough to determine a representatoive sample of every doctor in the world.

In a Euler diagram, “No X are Y” would be represented how?
Answer: Two separated circles, one called X and the other called Y.
(so there is no element of the set X that is also in the set Y)
Step-by-step explanation:
"No X are Y"
This means that there is not a single element in the set X that is also in the set Y.
So in an Euler diagram, you can represent this as two circles, one called Y and other called X, where the circles do not intersect or touch at any point.
This particular case is represented similarly to how you would represent it in a Venn diagram
