A company has two packaging machines in a unit, each with a different daily capacity. The capacity of machine 1 is defined by th

ollegr [7]

Total capacity = sum of the individual production capacities.

Here,

Total capacity = sum of f(m) = (m + 4)^2 + 100 and g(m) = (m + 12)^2 − 50.

Then f(m) + g(m) = (m + 4)^2 + 100 + (m + 12)^2 − 50.

We must expand the binomial squares in order to combine like terms:

m^2 + 8 m + 16 + 100

+m^2 + 24m + 144 - 50

---------------------------------

Then f(m) + g(m) = 2m^2 + 32m + 160 + 50

f(m) + g(m) = 2m^2 + 32m + 210, where m is the number of

minutes during which the two machines operate.

The number of column inches of classified advertisements appearing on Mondays in a certain daily newspaper is normally distribut

lana66690 [7]

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:

Step(i):-

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

$Z = \frac{x-mean}{S.D} = \frac{280-320}{20} = -2$

Let 'X' = 360

$Z = \frac{x-mean}{S.D} = \frac{360-320}{20} = 2$

Step(iii):-

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
