One way to measure self-discipline is the $1-now or $2-later test (which the researchers call the Delay Choice Task) in which we

see if a subject would decline to accept a dollar bill now when told they could wait a week and get two dollars. Highly self-disciplined adolescents outperformed their more impulsive peers on every academic-performance variable, including report card grades. Which of the following is correct?
A. This study is an experiment, since it was based on a random sample.
B. This study is an observation study since the researchers did not assign the students to one of the self-discipline categories.
C. This study is an experiment, since each subject was classified into a self-discipline category ($1-now or $2-later) and to report card grades.
D. This study is an experiment, since it was based on a random sample

Use the quadratic formula to solve the equation
azamat

Answer:

=3

=2

Step-by-step explanation:

12−5+6=0

using the Quadratic Formula where

a = 1, b = -5, and c = 6

=−±2−4‾‾‾‾‾‾‾‾√2

=−(−5)±(−5)2−4(1)(6)‾‾‾‾‾‾‾‾‾‾‾‾‾‾√2(1)

=5±25−24‾‾‾‾‾‾‾√2

=5±1‾√2

The discriminant 2−4>0

so, there are two real roots.

Simplify the Radical:

=5±12

=62=42

which becomes

=3

=2

hope this helps :)
