<u></u>1 \frac{32}{99}<u></u>

To easily convert repeating decimals into fraction most of them will have a denominator of 3, 7, or 9. Or multiples of those numbers. Note these are mainly prime. There are videos to help walk you through the process.  In your situation 2 places are repeating which means you take the numbers/99.

If you had 3 or 4 repeating decimals you would divide by 999 or 9999.

Many times the fractions can be simplified but in your case it cannot be simplified.

Your answer is<u> 1 and  32/99</u>

Why do we use a coeficient to remove the propotionality
Salsk061 [2.6K]
Constant is the scale term in proportionality. Suppose one variable is dependent on the other and one variable become twice, other becomes also twice and if one becomes half, other too becomes half., but they are two different variables which are no-where linked (like cost(money) vs quantity). Quantity and cost are two different things but they abridge a mathematical relation of proportionality. So in the mathematics to abridge these two different variables, we need something. Constant serves that purpose.

elena-14-01-66 [18.8K]

Answer:

a. z-score = -1.2

b. The age 23 years old is -1.2 standard deviations below the mean

c. The age is not unusual

Step-by-step explanation:

a. Transformation to z-score

Mathematically;

z-score = (x - μ)/σ

where σ and μ are the standard deviation and the mean respectively.

From the question, x = 23, μ = 27.2 and σ = 3.5

Let’s put these into the equation;

z-score = (23-27.2)/3.5 = -1.2

b. Interpretation of result

The interpretation is that 23 years old is -1.2 standard deviations below the mean

c. Determination

The age is not unusual. This is because any z-value below -2 or above 2 is considered unusual

-1.2 is above -2 and thus it is not unusual
