Let: Heifer= x
Cow= x+ 4812
x(x+423)= 8
x2 + 143x = 8
x2 + 143x + C = 8 + C
C= ( b2)2
C=( 143 × 12)2
C= (146)2
x2 + 143x+ (146)2 = 8+ (146)2
(x + 146) 2 = 1219
√ (x + 146) 2 = √1219
x + 146 = ± 113
x = ± 113 - 146
x = 43 or -6
Heifer is x equivalent to 113 years
Cow= 6 years.
*
x2= xy- 4
y = 2x- 3
let:
y= 2x-3
therefore x2 = x(2x-3) – 4
x2 = 2x2 – 3x – 4
then x2- 3x- 4= 0
x2- 3x + C = 4+ C
C= (b2 )2
C=( 32 )2 = 94
(x- 32 ) 2 = 4 + 94
√ (x- 32 ) 2 = √254
(x- 32 ) = ± 52 : x = ±52 + 32
When positive When negative
x= 4 x= -1
y= 5y = -5
f.
* Value of x = 22 given by total frequency less the sum of frequencies to individual classes.
* Modal class is given by the highest frequency (35 – 44)
* Median mark
Median class is given by:
N2 which is higher than cumulati...
