Answer:
The probability there will be between 280 and 360 column inches of classified advertisement
P(280≤X≤360) = P(-2≤Z≤2) = 0.9544
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean the population = 320
The standard deviation of the Population = 20
Let 'X' be the random variable in a normal distribution
Let 'X' = 280

Let 'X' = 360

<u><em>Step(iii):-</em></u>
The probability there will be between 280 and 360 column inches of classified advertisement
P(280≤X≤360) = P(-2≤Z≤2)
= P(z≤2) -P(z≤-2)
= P(z≤2)+P(z≤2)
= 2P(z≤2)
= 2×0.4772 ( from normal table)
= 0.9544
simplify the expression (4g^10)^4
<h2><em><u>
A.256g^40</u></em></h2>
B. 4g^40
C.256g^14
So hundreth is the 2nd number after the decimal point
that is the 6
so to round you take the numer before it so
69
if number is <u>></u>5 round up
if number is <5 round down
9 is >5 so round up
7
