Answer: $490,000
Explanation:
you take the gross income (annual in this case) and first multiply it by 70%(0.70). Then multiply it again by 7.
$100,000 x 0.70 = 70,000
70,000 x 7 = $490,000
Z = (x -μ)/σ
.. = (99 -88)/5

.. = 2.2
The z score is 2.2.
Answer:
Solving for the Percent by Volume
The v/v concentration of acetic acid in the stop bath is 24.6%.
Explanation:
To answer the question, we need to identify certain information stated in the question. Let us write down what’s given:
Volume of solute = 160 mL
Volume of solution = 650 mL
Next, we need to determine what is required, in this case, the percent by volume. Now, let us look at the formula:
v/v concentration = (solute volume / volume of the solution) * 100
Solution:
Percent by Volume = (160 / 650) * 100
Percent by Volume = 0.2461538461538462 * 100
Percent by Volume = 24.61538461538462
Rounded off = 24.6%
Therefore, the final answer is 24.6%
