Find the probability of the following.
A. P(z < 2.45)
B. P(1.2<z<1.4)
What is the probability or 4 out of 5 hands (dealer plus 4 players) receiving a "blackjack" (an Ace plus any 10 value card) all at the same time assuming all 104 cards are in play? Thank you
Let O be the set of odd numbers and O’ = {1, 5, 9, 13, 17, ...} be its subset. Define
the bijections, f and g as:
f : O "\\to" O’, f(d) = 2d - 1, "\\forall" d "\\in" O.
g : "\\Nu" "\\to" O, g(n) = 2n + 1, "\\forall" n "\\isin" "\\Nu" .
Using only the concept of function composition, can there be a bijective map from "\\Nu"
to O’? If so, compute it. If not, explain in details why not.
Consider the statement form (P↓Q)↓R.
Now, find a restricted statement form logically equivalent to it, in
a) Disjunctive normal form (DNF).
b) Conjunctive normal form (CNF).

Solve the equation
(a) 5(2 − x) ≤ 3x + 2 < 8
(b) 1/8 = 23x−4,
(c) logbx + logb(x − 4) = logb21
(d) log42x = 2
A passenger in an airplane at an altitude of 10 kilometers sees two towns directly to the east of the plane. The angles of depression to the towns are 𝛽 = 21° and 𝜃 = 59° (see figure). How far apart are the towns? (Round your answer to one decimal place.)

A conveyor is used to lift paper to a shredder. The most efficient operating angle of elevation for the conveyor is 37.8°. The paper is to be elevated 16.0 m. What length (in m) of conveyor is needed? (Round your answer to three significant digits.)
A bullet is found embedded in the wall of a room 3.2 m above the floor. The bullet entered the wall going upward at an angle of 34.3°. How far from the wall was the bullet fired if the gun was held 1.5 m above the floor?
Fire tower A is x = 29 kilometers due west of tower B. A fire is spotted from the towers, and the bearings from A and B are 𝜃 = N 78° E and φ = N 54° W, respectively (see figure). Find the distance d of the fire from the line segment AB. (Round your answer to two decimal places.)
