Answer:

Step-by-step explanation:

You take 1/2 the linear term's coefficient and square it.

The linear term is the term that contains just an x and a number -- in this case 12x

Take 1/2 12 = 6

and square it

6^2 = 36

So when you've done that you should get

x^2 + 12x + 36 = 11 + 36

x^2 + 12x + 36 = 47

1.) Any measure representing the center of a set of data arranged in a decreasing or increasing order of magnitude.

Marrrta [24]

Answer: The median is defined the measure of the central value when arranged in ascending or descending order of magnitude.
An average is a single number that represents the “middle” value of all the numbers in a list or set. There are three different types of average. These are called the mean, the median, and the mode.
When the given data is arranged in ascending (or descending) order, then the middle most observation is the median of the data. Mean, median and mode are the representative values of a group of observations. They are also called the measures of central tendency of the data.
If there are two numbers that appear most often (and the same number of times) then the data has two modes. This is called bimodal. If there are more than 2 then the data would be called multimodal. If all the numbers appear the same number of times, then the data set has no modes.
mode
The median is the middle score in a set of given numbers. The mode is the most frequently occurring score in a set of given numbers.

What is the five-number summary of the data set? 65 39 45 57 32 68 48 70 50

olga2289 [7]

List in ascending order:-

32 39 45 48 50 57 65 68 70

Q1 = (39+45)/2 = 42

Q2 = 50

Q3 = (65+68)/2 = 66.5

Correct option is the first one.

What is the perimeter of triangle DEF?

Mrac [35]

Answer:

(4.2 units)

Step-by-step explanation:

By inspection of the illustration we can see that leg DE has length 3 and that leg DF also has length 3. By the Pythagorean Theorem, 3^2 + 3^2 = 2(3^2); thus, the length of the hypotenuse EF is 3√2, or approximately 4.24 units. The third answer choice (4.2 units) is the correct one.
