What we want to measure is the taste of coffee.
The following were kept constant during the experimental investigation:
The type of coffee,
The type of percolator,
The same amount and type of water,
The same perking time,
The same electrical sources.
Because these items were kept constant, they are not expected to influence the outcome of the experimental investigation.
Define:
y = the metric used to measure the taste of coffee
x = amount of coffee grounds used for the taste experiment.
Therefore the relationship that arises from the experiment is
y = y(x).
Because x is controllable and is varied during the experiment, it is the independent variable.
Because the measured value of y depends on x, therefore y is the dependent variable.
Answer:
The taste of coffee is the dependent variable.
The amount of coffee grounds used is the independent variable.
The name of this compound is Ethyl propyl ether, CH3CH2OCH2CH2CH3 stands for Ethyl propyl ether.
Answer:
its already in scientific notation form however its ordinary or real form is -0.005682
Explanation:
scientific notation
when a number is expressed with some power of 10 multiplied by a number between 1 to 10 is called scientific notation
