1 answer:
Answer:
(a) 0.0968 (b) the probability that a randomly selected LU graduate will have a salary of exactly $30,400 is 0.0000 (c) 29.12% (d) 3000 students graduates this year from this university
Explanation:
Solution
For the problem given,
The average salary starting for this year's graduates at a large university (LU) is = 20,000
So,
The mean μ = $ 20,000
Standard deviation is б = $ 8000

Answer:
Final mass of Argon= 2.46 kg
Explanation:
Initial mass of Argon gas ( M1 ) = 4 kg
P1 = 450 kPa
T1 = 30°C = 303 K
P2 = 200 kPa
k ( specific heat ratio of Argon ) = 1.667
assuming a reversible adiabatic process
<u>Calculate the value of the M2 </u>
Applying ideal gas equation ( PV = mRT )
P₁V / P₂V = m₁ RT₁ / m₂ RT₂
hence : m2 = P₂T₁ / P₁T₂ * m₁
= (200 * 303 ) / (450 * 219 ) * 4
= 2.46 kg
<em>Note: Calculation for T2 is attached below</em>
