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.

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

Answer:

You can tell they are scaled copies because they retain the same shape as each other, even though they are different sizes. Another way you can tell is to find the measure of all the sides for both shapes and see if the ratio from the original to image is the same for all sides (indicating that all sides were scaled by the same amount)

Answer:

  it has 10 times the value

Step-by-step explanation:

In a base-10 number system, each digit to the left has a value 10 times the one to its right.

  3 in the thousands place has a value of 3000

  3 in the hundreds place has a value of 300

The digits values are related by a factor of 3000/300 = 10. The digit in the thousands place has 10 times the value of the digit in the hundreds place.

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".
