Answer:
a. P= 0.6364
b. P = 0.3636
c. Q = $21.25
d. P = 0.5
Step-by-step explanation:
given data
value of a stock varies = $13 to $24
solution
P (stock value is more than $17)
P =
P =
P = 0.6364
and
P (value of the stock is between $17 and $21)
P =
P =
P = 0.3636
and
Let the upper quartile be Q
(24 - Q) = 2.75
so
Q = $21.25
and
P(X > 20 | X > 16)
P =
P =
P = 0.5
Answer:
13
Step-by-step explanation:
(3 - 2i)(3 + 2i)
Expand
(9 + 6i - 6i - 4i^2)
Add
(9 - 4i^2)
Convert i^2
i^2 = ()^2 = -1
(9 - 4(-1))
Add
(9 + 4)
= 13
