Answer:
- <u><em>The lamp burns 6 ounces of oil per min.</em></u>
Explanation:
That the oil of a lamp burns at a <em>linear rate</em> means that the rate of burn is constant.
Hence, you can calcualte the rate with which the lamp burns the oil using any two ordered pairs.
- Rate of burn = [ change in oil ] / [change in time]
- Rate of burn = [Oil at time 2- Oil at time 1 ] / [time 2 - time 1]
Your two ordered pairs are (13 ounces, 10 min) and (7 ounces, 38 min).
Substituting those pairs in the equation for the rate, you get:
- Rate = [ 7 ounces - 13 ounces ] / [38 min - 10 min]
- Rate = ( - 6 ounces) / (18 min) = - 1/3 oz / min ≈ - 0.33 oz / min
The negative sign just shows that the amount of oil is decreasing (the oil is being burned).
Hence, the lamp burns 6 ounces of oil per min.
Answer:
d. it depends on the research hypothesis
Step-by-step explanation:
Given
Required
Mode of variable conceptualization
In all cases, the research hypothesis serve a guide to determine the variable and what to test in the variable.
It is also through the research hypothesis that the researcher will know the expected output and prediction of the experiment
What does this means?
It means that the researcher have to depend on the research hypothesis before they conceptualize the variable.
