The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24? y – 20 y – 14 y – 8 y – 6

aniked [119]

Just for future reference always put ^ for exponents. The answer is y-6 though.
(y-4)(y-6) create that trinomial. You can prove that by using the FOIL algorithm

What does the 3 represent in 3(20 15)?

Andre45 [30]

Depending on what you're supposed to do, the three could either mean to distribute it into the equation, giving you
either
(3*2015) or (3*20)*(3*15) or (3*20) +/- (3*15)

Or an example of factoring where they took 3 out of 60 and 45.

There are no instruction on what to do in this question.

Answer correclty

kolezko [41]

Answer:

2. B) The events have a strong positive linear correlation.

1. C) Find the slope using the slope formula:

$\frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

2. The correlation coefficient is 0,02, which is positive, so this would be the obvious choice.

1. You CANNOT write a linear equation without FIRST finding the rate of change [slope]. You will ALWAYS need the rate of change in order to write any linear equation.

I am joyous to assist you anytime.
