The scale factor enlarges or reduces the graph of the data set thus it will not change the shape thus option (D) is correct.

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".

Answer:

Step-by-step explanation:

30=17+x-12

Answer:

Step-by-step explanation:

let the width be w

p=l*w

1200= 200*w

1200= 200w

1200 = 200w

6 feet = w

width is 6 feet

let the length be a

p = l* w

1200 = a* 6

1200 = 6a

1200 = 6a

200 feet  = a

length is 200 feet

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

We use the nCr combination formula because order doesn't matter.

The number of ways Kyle’s choose eight to attend his birthday party is 43263.

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.

Answer:

No

Step-by-step explanation:

two thirds of 12 is 8

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.

8 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

9 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

10 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

11 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)

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:

Both alternate exterior angles are 104 degrees each, which confirms we have the correct x value.
