The z-score of a certain data point in the given statistical data is calculated through the equation,
                                           z-score = (x - m) / sd
where x is the data point, m is the mean and sd is the standard deviation. 
Substituting the known values,
                                           z-score = (51.8 - 52.3) / 1.8
                                           z-score = -0.277
Rounding the answer to the nearest tenth will give an answer of -0.3.

What is the value of x in the equation 3x-1/9=18 when y equals 27
anygoal [31]

Answer: 163/27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x + -1/9 = 18

Step 2: Add 1/9 to both sides.

3x + -1/9 + 1/9 + = 18 + 1/9

3x = 163/9

Step 3: Divide both sides by 3.

3x/3 = 163/9 over 3

x = 163/27

Easiest way to calculate 22% mark up from a cost of say 39.99
satela [25.4K]

Answer:

The markup amount on the cost 39.99 $ will be: 8.78 $

Step-by-step explanation:

Given

  • The cost = 39.99 (Let say in $)
  • Mark up = 22%

As

22% = 0.22

The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

so

Markup amount = 0.22 × 39.99

                           = 8.78 $

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $
