Answer:

  • Architect - $83000
  • Lawyer - $128000

Step-by-step explanation:

  • Salary of a lawyer = l
  • Salary of an architect = a

<u>According to the question we have:</u>

  • l = 2a - 38000
  • l + a = 211000

<u>Substitute l into the second equation and solve for a:</u>

  • 2a - 38000 + a = 211000
  • 3a = 211000 + 38000
  • 3a = 249000
  • a = 249000/3
  • a = 83000

<u>Find the value of l:</u>

  • l = 211000 - 83000
  • l = 128000

Answer:

Relative frequency is 7.41% or 0.0741

Step-by-step explanation:

Given

The Attached Table

Required

Calculate the relative frequency of the class with lower limit 27

Relative Frequency is calculated by dividing individual frequency by the total frequency

Mathematically,

Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}

The total frequency of the given data is 6+8+4+2+5+2

Total\ Frequency = 27

The class with lower limit 27 has a frequency of 2;

Hence;

Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency} becomes

Relative\ Frequency = \frac{2}{27}

Relative\ Frequency = 0.07407407407

Relative\ Frequency = 0.0741 (Approximated)

You may also leave your answer in percentage form

Relative\ Frequency = 0.0741 * 100\%

Relative\ Frequency = 7.41 \%

Hence, the relative frequency is 7.41% or 0.0741
