Answer:
Option D) s = 1
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 69
X = 68
Formula:
Computing z-scores for different standard deviation:
The standard deviation with highest z-score gives the most extreme position in the distribution.
Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.
Option D) s = 1
Answer:
(2, 5)
Step-by-step explanation:
Rotation clockwise 90° can be accomplished by the transformation ...
(x, y) ⇒ (y, -x)
so
(-5, 2) ⇒ (2, 5)
Answer:
$2,459.21
Step-by-step explanation:
(see attached for reference)
recall that the formula for compound interest is:
A = P [ 1 + (r/n)^ (nt) ]
where,
A = Final amount ( we are asked to find this)
P = principal amount = given as $2,340
r = Annual Interest Rate = given as 5% = 0.05
n = number of times compounded in a year = 4 (compounded quarterly)
t= time = 1 year
Substituting the values into the equation,
A = P [ 1 + (r/n)^ (nt) ]
A = 2,340 [ 1 + (0.05/4)^ (4·1) ]
A = $2,459.21
