For this case we have that by definition, a quadratic equation is of the form:

ax ^ 2 + bx + c = 0

Where the roots are given by:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}

We have the following equation:

x ^ 2-3x-2 = 0

Then, according to the definition, the values are:

a = 1\\b = -3\\c = -2

Answer:

a = 1\\b = -3\\c = -2

Answer:

The values of a, b, and c in the quadratic equation are:

a=1\\b=-3\\c=-2

Step-by-step explanation:

The general form of a quadratic equation is as follows

ax^2 + bx +c

Where a, b and c are real numbers that represent the coefficients of the quadratic equation and a \neq 0

In this case we have the following quadratic equation

x^2 - 3x - 2

Therefore, notice that:

a=1\\b=-3\\c=-2

y=3x+6

Use

y=mx+b

to calculate the equation of the line, where

m

represents the slope and

b

represents the y-intercept.

Slope is equal to the change in

Which set of values are in the solution set of 3x + 2 > 8?
devlian [24]

9514 1404 393

Answer:

  D.  3, 4, 5, 6

Step-by-step explanation:

  3x + 2 > 8 . . . . . . given

  3x > 6 . . . . . . . . . subtract 2 from both sides

  x > 2 . . . . . . . . . . divide both sides by 2

Any set of values that includes 2 or any smaller numbers is NOT a solution set. The only set with numbers greater than 2 is ...

  D.  3, 4, 5, 6

Using the formula below or Excel, find the correlation coefficient, r, for this set of scores. Answer choices are rounded to the
RideAnS [48]

The correlation coefficient measures the relationship between the two variables

The correlation coefficient is 0.234

<h3>How to determine the correlation coefficient</h3>

The formula of correlation coefficient is:

r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})

Using the dataset from the complete question, we have:

r = \frac{1}{5 - 1} * 0.9375

Evaluate the difference

r = \frac{1}{4} * 0.9375

Evaluate the quotient

r = 0.234375

Approximate

r = 0.234

Hence, the correlation coefficient is 0.234
