I think it is 9 6/9 but im not quite sure .
3 x 4 is equal to 12 I think that’s your answer
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%
(D) -3w2<span> - 9w - 4
I hope this helped :)
