Ronch [10]

Answer:

0.5, 0.15, 0.115, 0.005

Step-by-step explanation:

A number can be written from the greatest to the and the lowest to the highest when given a series of number. This series of number can be in mixed fraction forms, improper fraction or decimal. When a number is said to be written from the greatest to the lowest, it is called descending order but from the lowest to the greatest it is called ascending order.

From the list of the series of the decimal numbers given, writing the numbers in order from the greatest to the least number will choose the form:

0.5, 0.15, 0.115, 0.005

What is the range of y = (x - 5)^2 – 1?

Setler79 [48]

1. The graph is a parabola.

2. The parabola opens up, because there's no negative number in front of $(x-5)^2$ .

3. The vertext is (5,-1), because of the vertex form.

This means that that -1 will be the least y-value used on the graph and the garph will open up from there.

The range is (-1, infinity) or { y | y > -1 }.

The following data set represents the salaries of all seven employees at a small start-up company (expressed in thousands of dol

bogdanovich [222]

Answer:

Step-by-step explanation:

If the data set represents the salaries of all seven employees at a small start-up company (expressed in thousands of dollars). 23, 25, 40, 45, 45, 23, 23 in thousands dollars with variance of 99.14, to get the standard deviation, the formula below will be applicable.

Variance = (standard deviation)²

substituting Variance = 99.14 into the equation we wil have;

99.14 = (standard deviation)²

taking the square root of both sides;

√99.14 = √(standard deviation)²

standard deviation = √99.14

standard deviation = 9.96

The standard deviation of the set of datas is 9.96
