Answer:

factorization and simplification

Step-by-step explanation:

Algebraic equations can be long and complicated. This results in the equations being complicated in themselves. There are several methods that are used to solve the long complicated equations. These involve the following methods:

Factorization  - factorization factors out the common factors and allows the equation to be solved.

Simplification - this is an operative that allows the reduction of the equation to the lowest terms so that it can be solved.

1. use PEMDAS to do the problem in the correct order, put like terms together
2. Inverse operations help by plugging the value back into the equation and ensuring you have the right answer.
3. Construction workers may do the inverse to make sure they have the correct measurements for walls or something.

The long-distance calls made by the employees of a company are normally distributed with a mean of 6.3 minutes and a standard de
Sergio [31]

To solve this problem, we use the formula:

z = (x – u) / s

where z is the z score value which can be obtained from the tables, x is the sample value, u is the mean = 6.3 min, and s is the std dev = 2.2 min

 

at P value = 0.90, the z = 1.28, finding for x:

x = z s + u

x = 1.28 * 2.2 + 6.3

x = 9.116

 

at P value = 1.0, the z = 3.49, finding for x:

x = z s + u

x = 3.49 * 2.2 + 6.3

x = 13.978 ~ 14

 

Therefore the longest 10% calls last about 9.1 minutes to 14 minutes

Order the data from lest to greatest 35, 24,25,38,31,20,27
kolbaska11 [484]

Answer:

Step-by-step explanation:

20,24,25,27,31,35,38

minimum;20

medium: 27

maximum: 38

lower quartile: 24

upper quartile:35

put numbers in number order

the first number is the minimum, the last number is the maximum. the middle number "split" is the median.

quartiles are the numbers in the middle of the data you just "split"

(so like a quarter)

i may be wrong i haven't done this in years
