Answer:
Data Set 2 has the same mean as Data Set 1.
and
Data Set 2 has a larger standard deviation than Data Set 1
Step-by-step explanation:
Mean of both data sets is the same = 6
Data set 2 has a larger standard deviation since the data values are further away from the mean than the data values in data set 1 are from the mean and standard deviation is a measure of variance i.e. how far data set values are from the mean
60 is the last option

flor compró 2 enterOS 5/8 m de la tela roja, 1 entero 1/3 m de la tel< azul y 3 enteros 1/6m de la tela amarilla ¿cuantos metros de tela compró en total.
The fraction of the fabric is 7 3/24m.
How to calculate the fraction?It should be noted that from the information, Flor bought different fractions of fabric and we want to calculate the total.
Therefore the total fractions will be:
= 2 5/8 + 1 1/3 + 3 1/6
= 2 15/24 + 1 8/24 + 3 4 / 24
= 6 27 / 24.
= 7 3/24
The total fraction is 7 3/24 m.

Consider the infinite geometric sequence that has a third term equal to -1/6 and a sixth term equal to -1/1296. What is the sum to infinity of the terms of this sequence?
The sum to infinity of the terms of this sequence is -36/5
What is the sum to infinity of the terms of this sequence?The given parameters are
T3 = -1/6
T6 = -1/1296
The nth term of a geometric sequence is
Tn = a * r^(n-1)
So, we have
T3 = ar^2
T6 = ar^5
Divide both equations
T6/T3 = ar^5/ar^2
Evaluate the quotient
T6/T3 = r^3
Substitute T3 = -1/6 and T6 = -1/1296 in T6/T3 = r^3
(-1/1296)/(-1/6) = r^3
Evaluate the quotient
1/216 = r^3
Take the cube root of both sides
r =1/6
Substitute r =1/6 in T3 = ar^2
T3 = a(1/6)^2
This gives
T3 = a/36
Substitute T3 = -1/6 in T3 = a/36
a/36 = -1/6
This gives
a = -6
The sum to infinity of the terms of this sequence is
S = a/(1 - r)
This gives
S = -6/(1 - 1/6)
This gives
S = -6/(5/6)
Evaluate
S = -36/5
Hence, the sum to infinity of the terms of this sequence is -36/5

The statement "Is $24 Dave’s after 3 weeks;$52 saved after 7 weeks equivalent" is false
This is further explained below.
What is equivalence?Generally, Expressions are considered to be equivalent if their function is the same despite their appearance being distinct.
If two algebraic expressions are equivalent to one another, then those two expressions will provide the same result when we use the same value for the variable in each expression.
In conclusion,
Firstly, we consider what Dave saves in one week will be,
Since $24 Dave’s after 3 weeks we have

How to fine the line that is parallel to the given lineGiven data
line y = -2x/3 + 1
The equation of a line is represented as y = mx + c where m represents the slope. The unique feature of parallel line is that the slopes are equal.
Hence we find the line that has same value of m which is the slope
using the second option: 2x+3y=-18
2x + 3y = -18

What would be the combined cost of 1 yard of blue fabric and 1 yard of green fabric? LaTanya buys 5 yards of blue fabric and 8 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $62. What would be the combined cost of 1 yard of blue fabric and 1 yard of green fabric?
The price of green fabric = $4 and the price of blue fabric is $6.
How to illustrate the information?It should be noted that LaTanya buys 5 yards of blue fabric and 8 yards of green fabric and the blue fabric costs $2 more per yard than the green fabric.
Let the price of the green fabric = x
Price of blue fabric = x + 2
Therefore, the expression will be:
5(x + 2) + 8(x) = 62
5x + 10 + 8x = 62
13x = 62 - 10
13x = 52
Divide
x = 52/13
x = 4
The price of green fabric = $4
The price of blue fabric = $4 + $2 = $6

The coordinates of the vertices of quadrilateral ABCD are (−6,−1), (−5,2), (−1,−5), and (0,−2). Parker states that quadrilateral ABCD is a parallelogram. Prove or disprove Parker’s statement.
As the length of the sides AD ≠ BC the given quadrilateral ABCD is not a parallelogram.
What approach proves the lines are parallel?To prove that the given lines are parallel we have to determine their slope if the slope if equal then the lines are parallell.
We know that a quadrilateral is a parallelogram when opposite lines are of the same length and opposite lines are parallel to each other.
Given a quadrilateral, ABCD has coordinates A(−6,−1), B(−5,2), C(−1,−5), and D (0,−2).
∴ The quadrilateral ABCD t be a parallelogram length of AB = DC and length of AD = BC.
We know the distance formula is [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
So, lenght of AB = [tex]\sqrt{ (-5+6)^2 + (2 + 1)^2[/tex].
AB = [tex]\sqrt{ 1 + 9}[/tex].
AB = [tex]\sqrt{10}[/tex] units.
Lenght of DC = [tex]\sqrt{(0+1)^2 + (-2+5)^2}[/tex].
DC = [tex]\sqrt{10}[/tex] units.
Now length of AD = [tex]\sqrt{0+6)^2 + (-2+1)^2[/tex].
AD = [tex]\sqrt{ 37}[/tex] units.
Length of BC = [tex]\sqrt{(-1+5)^2 + (-5+2)^2[/tex].
BC = [tex]\sqrt{25}[/tex].
BC = 5 units.
As BC ≠ AD therefore quadrilateral ABCD is not a parallelogram.
