_______ the problem by formulating assumptions and recognise certain variables and their relations
patriot [66]

Answer:

Research Hypothesis solves the problem by .....

Step-by-step explanation:

Research Hypothesis is a set of assumed statements, consisting certain variables & their relationships

The variables whose relationship are to be checked by hypothesis testing, are independent & dependent variables. The causal variable(s) are independent variables & the effected variable is the dependent variable.

  • Null Hypothesis : It is the hypothesis assuming no statistically significant relationship between independent & dependent variables
  • Alternate Hypothesis : It is the hypothesis assuming statistically significant relationship between independent & dependent variable

Example : To check the research question, of relationship between research variables, by formulating hypothesis assumed statement

Y = b0 + b1X ; where

Y = dependent variable, X = independent variable, b0 = autonomous, b1 = X intercept on Y  

  • H0 : b1 = 0 {No significant relationship between X & Y}
  • H1 : b1 ≠ 0 {Significant relationship between X & Y}

This way : Research hypothesis solves the problem by - formulating hypothesis assumptions, which recognise the variables & their relations. At last, acceptance of null  or alternate hypothesis gives the final research conclusion & interpretation

What is the markup percent on a diamond for which the markup is $870 and the selling price is $2870?
ryzh [129]

Answer:

30.31%

Step-by-step explanation:

Mark up on selling price is given by markup*100%/selling price

In this case, markup is given as $870 while the selling price is $2870 hence the percentage of narkup to selling price will be given by \frac {870\times 100}{2870}=30.313588850174\approx 30.31

Therefore, the percentage of markup to selling price is approximately 30.31%

Find variable values for two variables in an equation
never [62]

Simplifying

2x + 3y = 12

Solving

2x + 3y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

2x + 3y + -3y = 12 + -3y

Combine like terms: 3y + -3y = 0

2x + 0 = 12 + -3y

2x = 12 + -3y

Divide each side by '2'.

x = 6 + -1.5y

Simplifying

x = 6 + -1.5y

rewrite as equivalent rational expressions with denominator (3x−8)(x−5)(x−3). 4/3x2−23x+40,9x/3x2−17x+24
saul85 [17]

Answer:

Step-by-step explanation:

\frac{4}{3x²-23x+40}

=\frac{4}{3x²-15x-8x+40}

=\frac{4}{3x(x-5)-8(x-5)}

=\frac{4}{(x-5)(3x-8)}

=\frac{4(x-3)}{(x-5)(3x-8)(x-3)}

2.

\frac{9x}{3x²-17x+24}

=\frac{9x}{3x²-9x-8x+24}

=\frac{9x}{3x(x-3)-8(x-3)}

=\frac{9x}{(x-3)(3x-8)}

=\frac{9x(x-5)}{(3x-8)(x-5)(x-3)}
