If the sum of a number and 6 is tripled,the result is one less than twice the number ? What is X?

1 answer:

Well 6 is tripled so write a expression/phrase.
3(x + 6)
The result is one less than twice the number.
2x - 1
Put it all together to make an equation and solve.
3(x + 6) = 2x - 1
3x + 18 = 2x - 1
3x - 2x = -1 - 18
x = -19
Check to make sure it works.
3(-19 + 6) = 2(-19) - 1
3(-13) = -38 - 1
-39 = -39 < The equality confirms our solution of x = -19
Hope this helps!

The main purpose of EFA is to find out the relationship between variables.

EFA is an abbreviation for exploratory factor analysis, which is used to determine the link between variables that are assessed.
Exploratory factor analysis is a statistical tool used in multivariate statistics to find the underlying structure of a rather large set of variables. EFA is a factor analysis approach with the overriding purpose of identifying the underlying connections between measured variables.
The common factor concept underpins EFA. Manifest variables are expressed as a function of common components, unique factors, and measurement errors in this model. Each distinct component has an effect on only one manifest variable and does not explain relationships between manifest variables. Common factors impact several manifest variables, and "factor loadings" are measurements of a common factor's influence on a manifest variable.

A. in terms of the number of marked elk, what is the relative frequency of male elk, female elk, adult elk, and baby elk? write

mash [69]

The relative frequency of the marked elks are:

Male Elk = 7/30
Female Elk = 4/15
Adult Elk= 173/450
Baby Elk = 26/22

<h3>How to determine the relative frequency?</h3>

From the complete question, we have:

Male = 105
Female = 120
Adult = 173
Baby = 52
Total = 450

The relative frequency of each is then calculated as:

Male Elk = 105/450

Male Elk = 7/30

Female Elk = 120/450

Female Elk = 4/15

Adult Elk= 173/450

Baby Elk = 52/450

Baby Elk = 26/22

<h3>The number of Elks in the park</h3>

Using the data in (a), we can conclude that:

There are 105 male, 120 female, 173 adult, and 26 baby in the park
