If you suspect that "hours studied" and "score on a math test" are positively correlated, what does that mean?

Answer:

D. Both A and B are true

Step-by-step explanation:

Why would you study to decrease scores? so C. Is automatically wrong. Now A. is true and B. is true. D says both A and B are true so D is correct.

Using the 4 train car strategy for factoring polynomials, what is the green common factor for the 1st two train cars and the gre
koban [17]

The completely factored expression of 2x^2 + 4x + 3xy + 6y is (2x + 3y)(x + 2)

<h3>How to factor the polynomial?</h3>

The expression is given as:

2x^2 + 4x + 3xy + 6y

Group the expression into two

[2x^2 + 4x] + [3xy + 6y]

Factor out each group

2x(x + 2) + 3y(x + 2)

Factor out x + 2

(2x + 3y)(x + 2)

Hence, the completely factored expression of 2x^2 + 4x + 3xy + 6y is (2x + 3y)(x + 2)

Correct function combinations to x2-7x-18
Natasha_Volkova [10]

The factors of the function after factorization f(x)=x^{2} -7x-18 is (x+2) and (x-9)

Given Function  f(x)=x^{2} -7x-18 and we have to find the factors of the given function.

The function whose factors are to be found is   f(x)=x^{2} -7x-18

Factorization means finding various expressions which when together multiplied will give the  function itself. Correct combination can only be found by finding the factors of the function. Without finding factors no one can find the solution of an equation or expression also.

f(x)=x^{2} -9x+2x-18

=x(x-9)+2(x-9)

=(x+2)(x-9)

Hence the  factors which when combine together gives function f(x)=x^{2} -7x-18 are (x+2)(x-9).
