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.

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.

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:

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 prime factorization of the given value is 2 × 2×2×√7

Prime factorization is the number of expressions written as a product of its prime factors.

Given the value 2√112

Prime numbers are numbers that can only be divisible by itself and 1.

2√112 = 2(√2×2×2×2×7)

2√112 = 2(√2⁴×7)

2√112 =  2(2²×√7)

2√112 =  2 × 2×2×√7

Hence the prime factorization of the given value is 2 × 2×2×√7

============================================================

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.
