Given A={2,4,6,8,…}

B={3,6,9,12,…}

C={1,2,3,6}

U= {1,2,3,4,5,6,7,8,9,10}

A’ = {1,3,5,7,9}

B’ = {1,2,4,5,7,8,10}

C’ = {4,5,7,8,9,10}

A’nB’nC’ = {5, 7}

Cost of each premiere ticket = $18.50

At bulk purchase, cost of each = $80.00/50 = $16.00

Amount saved = $18.50 – $16.00

=$2.50

2ai).

p = (rk/Q -ms)2/3

p3/2 = (rk/Q -ms)2/8 * 3/2

p3/2 = rk/Q = ms

p3/2 + ms = rk/Q

q(p3/2 + ms ) = rk

Q =rk/p3/2 + ms

2aii)

Where :

r = 10, k = 4, s = 0.2

p = 3, m = 15

Q = 10 * 4/3^3/2 + (15 * 0.2)

Q = 40/5.2 + 3

Q = 40/8.2

Q = 4.88

But m= 3 n = -2 x= -1

= 2*3*(-2)^2*(-1)/3(3)-(-2)

= 2*3*4*-1/9+2

= -24/11

Total income = 32+m+25+40+28+45

=170+m

PR(Â²)=m/170+m = 0.15/1

M=0.15(170+m)

M=25.5+0.15m

0.85m/0.85=25.5/0.85

M=30

**(5b)**

Total outcome = 170 + 30 = 200

PR(even numbers) = 30+40+50/200

**11b)** 8y = – 4x + 24

Y = – 4/8 x + 24/8

Y = – 1/2 x + 3

Gradient = m = – 1/2

:. Y- y1 = m(x-x)

Y- 12 = 1/2 (x + 8)

2(y-12) = 1 (x+8)

2y – 24 = -x-8

X + 2y – 24 + 8 = 0

X + 2y – 24 + 8 = 0

X + 2y – 16 = 0

Is the line above
