Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan C

Vikki [24]

Answer:

a. $435

b. 33.33%

Step-by-step explanation:

P.S - The exact question is -

Let Clara raised money = x

As given,

Ali raised 20% more than Clara

⇒Ali raised money = $x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x$

Also given,

Clara raised $\frac{1}{4}$ times more than Shan

Clara raised money = Shan raise money + $\frac{1}{4}$ times shan raired money

⇒Clara raised money = $\frac{5}{4}$ Shan raised money

⇒Shan raised money = $\frac{4}{5}$ times Clara

⇒Shan raised money = $\frac{4}{5}$ x

As given,

Ali raised $58 more than shan

⇒ $\frac{6}{5}x = \frac{4}{5}x + 58$

⇒ $\frac{6}{5}x -\frac{4}{5} x = 58$

⇒ $\frac{2}{5}x = 58$

⇒x = (29)(5) = $145

∴ we get

Clara raised money = x = $145

Ali raised money = $\frac{6}{5}x$ = $174

Shan raised money = $\frac{4}{5}$ x = $116

a.)

Total raised money = $145 + 174 + 116 = $435

b.)

Percentage of money Clara raised = $\frac{145}{435}$ ×100% = $\frac{1}{3}$ ×100% = 33.33%

Briefly explain how multiple regression enhances the two primary purposes of regression analysis.

maria [59]

The statistical goal of multiple regression analysis is to build a linear equation model that identifies the optimal weighted linear combination of independent variables in the study in order to optimally predict the reference variable.

Regression analysis is usually performed for one of two purposes. Predicting the value of the dependent variable of a person whose information about the explanatory variable is available, or estimating the effect of the explanatory variable on the dependent variable.

In multiple regression analysis, researchers can determine the strength of the relationship between the outcome (dependent variable) and multiple predictors, and the importance of each predictor in the relationship, often the effect of other predictors. It can be evaluated by statistically eliminating it.

Beth purchased a computer, and its value depreciated exponentially each year. Beth will sketch a graph of the situation, where x

Katyanochek1 [597]

What is x?

It is the number of years since purchase. Can this be negative?

NO! Years cannot be negative. So we disregard negative x-axis.

What is y?

It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?

NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.

The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).

ANSWER: Quadrant I only
