a small business has an average income of 3000 per month with a standard deviation of 250. if the income in a given month is 330

Vika [28.1K]

Answer:

The correct answer is z = 1.2

Step-by-step explanation:

μ or average income = US$ 3,000

σ or standard deviation = US$ 250

Income in a given month = US$ 3,300

For calculating the z score, we use the following formula:

z = (x – μ) / σ

z = (3,300 – 3,000 / 250)

z = 300/250

z = 6/5 = 1.2

Interpreting z

A Z score tells us how many units of standard deviation (1.2 in this case)from the average a given score is, that is, we do not count in quantity of points, but in quantities of standard deviations. To use the Z score we require the distribution to be normal and to know the average and standard deviation of the scores.

Here's another Math one worth 10.

tia_tia [17]

In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The short leg is the side opposite the 30 degree angle. If the short leg =x, then the hypotenuse = 2x

The ratio of the short leg to the hypotenuse in the given triangle is cos(60°)

$
cos(60^o) = \frac{adjacent \ side}{hypotenuse } = \frac{x}{2x} = \frac{1}{2}$
