Find the numerical values of -3|x|+2x-1 if x=-5. PLSSSS HELP
Kisachek [45]

Answer:

26

Step-by-step explanation:

Since x = -5, we can replace x with it's numerical -5, right? The problem tells you that x is equal to -5. So, just replace any x you see with -5.

So in this case,

-3|x|+2x-1

turns into:

-3|(-5)|+2(-5)-1

You can use a calculator or solve it by hand to see what the answer is.

-3|(-5)|+2(-5)-1\\-3(5)+2(-5)-1\\-15+(-10)-1\\-25-1\\-26

A forester wishes to predict the volume (in cubic feet) of usable lumber in a certain species of tree using the height (in feet)
alex41 [277]

Answer: The response variable = Volume

and explanatory variable(s) in this study are: Height and Diameter.

Step-by-step explanation:

Important definitions:

  • The explanatory variable is a type of independent variable manipulated by the experimenter for the ongoing experimental study.
  • The response variable is a type of dependent variable which depends on the explanatory values provided by the experimenter.

Given: A forester wishes to predict the volume (in cubic feet) of usable lumber in a certain species of tree using the height (in feet) and diameter (in inches) of the trees.

Here, Volume directly depends upon the height and diameter of the tree.

Also, forester ( Experimenter) wants to predict volume by cutting tree that means it is an response variable and it depends on height and diameter , so height and diameter are explanatory variable.

Hence, The response variable = Volume

and explanatory variable(s) in this study are: Height and Diameter.
