The answer is a because when u divide that number by 6 u get a whole number
<span>a)
Z*_Upper = (76 - 62.7)/2.5 = 5.32
Z*_Lower = (57 - 62.7)/2.5 = -2.28
The requirement is to get p(-2.28 < Z < 5.32) = p(Z<5.32) - p(Z<-2.28).
Use normal distribution table to get the answer for p and multiply with 100 to get the percentage.
The other questions are now easy for you to answer on your own. Hope it helps.

Answer:
=x+2
Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
given that y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition x = 2 when y = 11
k = yx = 11 × 2 = 22
y = ← equation of variation
