Expected value    (3 * 8  +   2*6)/10 = 3.6

with one additional '6'

(3*8 + 3*6 ) /11 = 3.82

(a²-2)(a²-3)

4(1250-x) = (1490+x)      solve for x

Slope m, of given line = -2/3        perpindicular slope = - 1/m = 3/2

Point slope form of new line    (y-2) = 3/2 (x+4)    <=====   re-arrange to desired form

(2²)¹⁰ ( 2³)²⁰ (2⁴)³⁰

2²⁰⁰

a =b/c  k       where k  is proportionality constant

ac/b = k

Sub in the values given

  3*9 /5   = 27/5

Sub in the second set of numbers

 4c/3 = 27/5

c = 4.05

h-80 =1/2 (a+80)   

    so    h =1/ 2a +120

then

h-110 = 1/3 (a+110)   

    so    h = 1/3 a + 110/3 + 110

equate the h's

1/2 a+120 = 1/3 a + 110/3 + 110

1/6 a = 110/3 + 110 - 120

a = 160         then    h = 200                   <====== you can add them together

There are   4 x 6 = 24 possible combos of a and b

   the only primes would be   1 * 5     1*7        two out of 24  = 1/12

s/c = 8/5

s = 8/5 c

8/5 c * 20    +     c * 4 = 900

c = 25        then s = 40

rate * time = distance

distance / rate = time

The distance Edwyn must ride his steel horse is a constant.

d/10 = (x +1)    d = 10(x+1)

d/15 = (x-1)      d = 15(x-1)           equate the d's

15(x-1) = 10(x+1)

5x = 25

x = 5   hours                         d = 10 ( x+1) = 60 miles
