Each respondent in the Current Population Survey of March 2005 was classified as employed, unemployed, or outside the labor forc

e. The results for men in California age 35-44 can be cross-tabulated by marital status, as follows:Employed: 790 (Married), 98 (Widowed, divorced or separated), 209 (Never married)Unemployed: 56 (Married), 11 (Widowed, divorced or separated), 27 (Never married)Not in labor force: 21 (Married), 7 (Widowed, divorced or separated), 13 (Never married)Men of different martial status seem to have different distributions of labor force status. Or is this just chance variation? (You may assume the data came from a simple random sample.)

We know that college GPA is positively correlated with salary after college. If we use knowledge of a student's GPA to predict h
anygoal [31]

Answer:

Step-by-step explanation:

Given that college GPA is positively correlated with salary after college

This means there is a positive linear relationship between GPA and salary after college.

Or we can write one as dependent and another as independent.

Since in the given question Salary is to be found out for given GPA we can make GPA as independent variable and Salary after college dependent variable

We will find a linear relationship as

Salary = slope * GPA + intercept

So

If we use knowledge of a student's GPA to predict his or her salary, the criterion variable is __GPA_____ and the predictor variable is __Salary after college._____.

Kumar has twice the number of goals as Jacob. Make an algebraic expression. Plzzzz help
alekssr [168]

The algebraic expression is x = 2y where, "x" is the number of goals with Kumar and "y" is the number of goals with Jacob

<em><u>Solution:</u></em>

Given that Kumar has twice the number of goals as Jacob

To find: algebraic expression

An algebraic expression is a mathematical expression that consists of variables, numbers and operations

<em><u>Let us first define the variables</u></em>

Let "x" be the number of goals with Kumar

Let "y" be the number of goals with Jacob

Then from given statement,

Number of goals with kumar = twice the number of goals as Jacob

Number of goals with kumar = 2(number of goals with Jacob)

x = 2y

Thus the algebraic expression is found

What is x over 2+ 4&lt;7
N76 [4]
 x/2 + 4 < 7

multiply both sides by 2
x/2 * 2 + 4 * 2 < 7 * 2
which equals
x + 8 < 14
subtract 8 from both sides
x + 8 - 8 < 14 - 8
x < 6

Let f (x) be a polynomial function with a zero of multiplicity of 1 at 2 and a zero of multiplicity of 2 at 1. Let g(x) be the r
Stella [2.4K]

The polynomial functions in their expanded form is given as follows. It is right to state that there are no breaks in the domain of h(x).

<h3>

What is a polynomial function?</h3>

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.

For instance, the polynomial 3x+4 has an exponent of 1.

Part A: F(x) has zero at 2 and multiplicity of 1; and

1 at the multiplicity of 2

f(x) = x-2) (x-1)²

= (x-2) (x² - 2x + 1)

= x³ - 4x² + 5x -2

Part B: h (x) = \left \{ {{x^3 -4x^2 + 5x -2; X < 0} \atop {\sqrt[3]{x-2} ; X\geq 0 }} \right.

The domain of X is X ∈ R

Hence it is correct to state that there are no breaks in the domain of h(x).
