Answer:
Option C) 0.57
Step-by-step explanation:
We are given the following in the question:
Average, = 260 calories
Standard deviation, = 35 calories
= 240 calories.
We have to find the Cohen's d effective size.
Formula:
Thus, the Cohen's d effective size is 0.57
Thus, the answer is
Option C) 0.57
Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
The graph is below.
