You're looking for a value
such that
Because the distribution is symmetric, the value of
in either case will be the same.
Now, because the distribution is continuous, you have that
The mean for the standard normal distribution is
, and because the distribution is symmetric about its mean, it follows that
.
You can consult a
score table to find the corresponding score for this probability. It turns out to be
.
Multiply 50 by 0.90 because you take a discount of 10% off. 1.00 = 100% 0.10 = 10% 0.01 = 1% if you multiply 50 by 0.10 instead you get the amount that is discounted instead of the new selling price.
ANSWER
D.
EXPLANATION
The given function is
Comparing to the general form of a trigonometric sine function,
The amplitude is absolute value of A
The period is given by
is a shift to the right of 4 units.
and
is an upward shift of 9 units
Therefore the phase shift is (4,9).
The correct answer is D
The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.
<h3 /><h3>How to get the angle in radians?</h3>
Remember the relation:
180° = 3.14 radians.
Then:
60° = (60°/180°)*3.14 rad = 1.05 rad.
Now, for a circle of radius R, an arc defined by an angle θ has a length:
L = θ*R
Then the length of this arc is:
L = 1.05*1 unit = 1.05 units.
