Answer:
0
Step-by-step explanation:
Given :
Mean = 40 ; Standard deviation = 2
P(x < 28)
Obtain the Zscore :
Z = (x - mean) / standard deviation
P(Z < (28 - 40) / 2))
Z = (28 - 40) / 2
Z = - 12 / 2
Z = - 6
P(Z < - 6) = 0.000000
Let the width be w
Width = w
Length = w + 6
Area = a
a = w(w + 6)
a = w² + 6w
Answer: a = w² + 6w

<u>Answer:</u>
○ 
<u>Step-by-step explanation:</u>
Given the equation:
,
to solve for 
, we have to rearrange the equation to make its subject.
⇒ 
[expand brackets]
⇒ 
⇒ 
[add 
to both sides]
⇒ 
⇒ 
[subtract 96 from both sides]
⇒ 
⇒ 
[divide both sides by 20]
⇒
