Answer:
Gustavo used an experiment where the data is quantitative.
Step-by-step explanation:
Gustavo is trying to determine the probabilities of winning each of the four possible prices. Since he is calculating a number, e.g. 30% chance of winning a video game system, he is analyzing quantitative data. Quantitative data basically refers to numerical data or information. On the other hand, qualitative data refers to aspects or characteristics of things, e.g. blue color, soft/hard, etc. It does not deal with numbers.
This can be considered an experiment because it deals with causal relationships between variables (this causes that), while simulations only require some type of correspondence between variables.
Answer:
3.5 ( 12 + h)
Step-by-step explanation:
From the given information:
The expression 42 + 3.5h is factored out by taking the coefficient of the variable term is 3.5
So factoring 3.5 from the expression 42 + 3.5h, we get:
= 3.5 ( 12 + h)
3 minutes because half of 6 is 3 so 3 is the anwser.
