7 0

Answer:

(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

Step-by-step explanation:

Formulas are used to factorize the polynomials.

In the given question, we can see a difference of squares

the difference of squares can be factorized using the formula

a^2-b^2 = (a+b)(a-b)

Here a^2 and b^2 are squares and factorized as sum and difference of numbers.

So in the given options,

(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

What are the relative frequencies, to the nearest hundredth, of the rows of the two way table?
Nookie1986 [14]

Answer:            A         B

Group A        0.25      0.75

Group B        0.45      0.55

Step-by-step explanation:

Since we have given that

Number of people of A in Group A = 15

Number of people of B in Group A = 45

Number of people of A in Group B = 20

Number of people of B in Group B = 25

Total number of people in Group A = 15+45 = 60

Total number of people in Group B = 20+25 = 45

So, Relative frequencies will be given  below:

Relative frequency of A in Group A is given by

\frac{15}{60}=0.25

Relative frequency of B in Group A is given by

\frac{45}{60}=0.75

Relative frequency of A in Group B is given by

\frac{20}{45}=0.45

Relative frequency of B in Group B is given by

\frac{25}{45}=0.55

Hence,             A         B

Group A        0.25      0.75

Group B        0.45      0.55
