Answer:
X probability = 0.02
Cumulative frequency at x ( 6 ) = 1
Step-by-step explanation:
X P ( X ) Cf ( X )
1 0.58 0.58
2 0.18 0.58 + 0.18 = 0.76
3 0.10 0.76 + 0.10 = 0.86
4 0.07 0.86 + 0.07 = 0.93
5 0.05 0.93 + 0.05 = 0.98
6 0.02 0.98 + 0.02 = 1
a) Reduction because the second figure is smaller than the original one.

<span>5y^2+4y-1
= 5y^2 + 5y - y - 1
= 5y(y+1) - 1(y+1)
= (y+1)(5y -1) or
= (5y-1)(y +1)
answer
</span>(5y-1)(y +1)
