Answer:
x = 5.56
Step-by-step explanation:
Sin(17) = 
=> Isolate the "x"
Sin(17) * 19 = x
5.56 = x
Hope this helps!
Answer:
This was an observational study.
Step-by-step explanation:
Given is that parents of children completed a questionnaire on the child’s light exposure both at present and before the age of 2 years.
This was an observational study since there is no treatment or control group.
We know that treatment, control groups or treatment groups are not specific to randomized control experiments.
Answer:
The answer to your question is: (1/2, 5)
Step-by-step explanation:
Parabola f(x) = 8x² - 8x + 7
y = 8x² - 8x + 7
Vertical Parabola equation
( x - h)² = 4p (y - k) Transform the original equation to this form
8x² - 8x = y - 7
8(x² - x + ( )²) = y - 7 Complete squares
8 (x² - x + (1/2)²) = y - 7 + 2 Simplification
8 (x² - x + 1/4) = y - 5
(x - 1/2)² = 1/8 (y - 5)
Finally Vertex
(1/2 , 5)
The general formula for the sum of the n terms of a geometric progression is:
Sn = A1 (1 - r^n) / (1 - r)
In this case, n = 8; A1 = - 11, r = -4
S8 = -11 (1 - (-4)^8) / (1 -(-4)) = 144,177
Answer: option c.
