Which equation is correct?
8 dot 8 equals 8 Superscript 2 equals 16.
9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18.
10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100.
11 dot 11 equals 11 Superscript 2 equals 121.
The equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)
From the question,
We are to determine which of the options is correct.
To determine which of the options is correct, we will evaluate the options one after the other.
For the first option8 dot 8 equals 8 Superscript 2 equals 16
That is,
8.8 = 8² = 16
Evaluating properly
8.8 = 8² = 8 × 8 = 64
Then, 8.8 = 8² ≠ 16
∴ This is NOT correct
For the second option9 dot 9 equals 2 left-parenthesis 9 right-parenthesis equals 18
That is,
9.9 = 2(9) = 18
Evaluating properly
9.9 = 9 × 9 = 9² = 81
Then, 9.9 ≠ 2(9) = 18
∴ This is NOT correct
For the third option10 dot 10 equals 2 left-parenthesis 10 right-parenthesis equals 100
That is,
10.10 = 2(10) = 100
Evaluating properly
10.10 = 10 × 10 = 10² = 100
Then, 10.10 ≠ 2(10) ≠ 100
∴This is NOT correct
For the fourth option11 dot 11 equals 11 Superscript 2 equals 121
That is,
11.11 = 11² = 121
Evaluating properly
11.11 = 11² = 11 × 11 = 121
Then, 11.11 = 11² = 121
This is correct.
Hence, the equation that is correct is 11.11 = 11² = 121. The correct answer is the fourth option: 11 dot 11 equals 11 Superscript 2 equals 121 (11.11 = 11² = 121)

Given lines are parallel, find the value of x.
Then determine the measure of the angle.
Answers:
x = 45angle measure = 104 degrees============================================================
Explanation:
These angles are on alternating sides of the transversal line, and they are exterior of the parallel lines. Therefore, these are alternate exterior angles.
Alternate exterior angles are congruent when we have parallel lines like this.
Set the two expressions equal to each other. Solve for x.
3x-31 = x+59
3x-x = 59+31
2x = 90
x = 90/2
x = 45
Then we can find that:
3x-31 = 3*45-31 = 135-31 = 104x+59 = 45+59 = 104Both alternate exterior angles are 104 degrees each, which confirms we have the correct x value.

When graphing data from a study the scale of the data:
A, may make the data misleading
B, should always be presented using a factor of 2.
C, is not important.
D, will not change how the data appears.
Answer:
B
Step-by-step explanation:
B no steps needed to do this
The scale factor enlarges or reduces the graph of the data set thus it will not change the shape thus option (D) is correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
The scale factor is used to enlarge any data set by the same multiplier.
For example, a coordinate (x,y) will be enlarged by (9x,9y) so 9 will be the scale factor.
The scale factor is useful to work with data which not lie in the range of the given axis in coordinate geometry.
When we apply the scale factor it will either enlarge or reduce the plot size but the shape will remain the same so the data representation will be the same.
Hence "The scale factor enlarges or reduces the graph of the data set thus it will not change the shape".

What is the slope of the line in the xy plane that passes through the points {-5/2 ,1} and {-1/2, 4}?
Answer:
m=3/2
Step-by-step explanation:
the line: y=mx+b
This line passes through the points
-> These points (x,y) are on the line
(-5/2,1) : x=-5/2 y=1
1=-5/2m+b
(-1/2,4) : x=-1/2 y=4
4=-1/2m+b
We have a system of equation:
1=-5/2m+b
4=-1/2m+b
After solving this, we have m=3/2 b=19/4
-> The slope is 3/2

The number of ways Kyle’s choose eight to attend his birthday party is 43263.
What is a combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by nCr and it is given by, ⁿCr=n!/r!(n−r)!,where 0 ≤ r ≤ n.
Given that, there are 24 student in Kyle’s kindergarten class.
He choose eight to attend his birthday party
Now, number of ways is
²⁴C₈= 24!/8!(24-8)!
= 24×23×22×21×20×19×18×17×16!/8! 16!
= 24×23×22×21×20×19×18×17/8×7×6×5×4×3×2×1
= 3×23×11×3×4×19×3×17/4×3
= 3×23×11×3×19
= 43263
Therefore, the number of ways Kyle’s choose eight to attend his birthday party is 43263.
