Answer:

The value of a is 16    

Step-by-step explanation:

Given the product

(y - 4)(y^2 + 4y + 16)

we have to apply the distributive property express the expression in the form

y^3 + 4y^2 + ay - 4y^2 - ay - 64\text{ to find the value of a}

By distributive property

a(b+c)=a.b+a.c

(y - 4)(y^2 + 4y + 16)

y(y^2 + 4y + 16)-4(y^2 + 4y + 16)

y^3+4y^2+16y-4y^2-16y-64

\text{Compare this equation with }y^3 + 4y^2 + ay - 4y^2 - ay - 64

gives a=16

hence, the value of a is 16

To approximate the P(x<27) we need to find the z-score of the data, this will be given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
x=27, μ=32, σ=4
z=(27-32)/4
z=-5/4
z=-1.25
thus
P(x<27)=P(z<-1.25)
=0.1056
=10.56%

Answer: 10.56%
