Answer:

A.This is the number of combinations of 6 from 15

= 15C6

=  15! / (15-6)! 6!

= 5,005 ways.

B.  This is the number of permutaions of 6 from 15:

= 15! / (15-6)!

= 3,603,600 ways.

Answer:

3x(x2 + 4)

Then use the distributive property

SO the final answer would be: 3x^3 +12x

To answer that question we need to use THE RULE OF THREE, this rule will help us solving linear relation problems.

Solution is:

The hour hand will turn (1/36)×π

The Table

Step      minute hand                hour hand

0-5         (1/6)×π                            (1/72)×π

  10        (2/6)×π                           (1/36)×π

  15        (3/6)×π   = π/2                (1/24)×π

  20       (4/6)×π   = (2/3)×π          (1/18)×π

  25       (5/6)×π                           (5/72)×π

  30       (6/6)×π   = π                   (1/12)×π

  35        (7/6)×π                          (7/72)×π

  40        (8/6)×π                          (8/72)×π

  45        (9/6)×π  = (3/2)×π         (3/24)×π

  50        ( 10/6)×π                       ( 10/72)×π

  55        (11/6)×π                          (11/72)×π

  60         (12/6)×π  = 2×π            (12/72)×π    = π/6

  • We know that each complete minute hand turn, is a 2×π angle turn, then a 5 minutes turn is (1/12) × 2×π = (π/6)
  • We will use that relationship to build the table and answer the question

If   2×π  angle for a minute hand turn is equal to 1 hour, then

(2/6) angle for a minute hand turn is equal to  "x" turn in the hour hand

So by Rule of Three, we proceed

2×π         ( Of minute hand)   ⇒    (1/6)×π   (of hour hand)

(2/6)× π   ( Of minute hand)   ⇒        x

Solving for x

2×π × x   = (2/6)× π × (1/6)×π

2× x  =  (2/36)×π

x = (1/36)×π

Now to build the table in 5 minutes steps:
