nlexa [21]

Answer:

The answer is : b) a confound

Step-by-step explanation:

While manipulating, is possible that some factors like noise in the hall, can affect learning in one of the groups but not in the other.

This possibility reflects the presence of a confound.

We can define a confounding variable as an external influencing factor which results in bringing changes in the effects of a dependent and independent variable.

This variable changes the outcome of an experiment and produces useless results.

Last week, it rained g inches. This week, the amount of rain decreased by 5%. Which expressions represent the amount of rain tha
dybincka [34]

Answer:

The correct answers are:

0.95g

g - 0.05g

(1 - 0.05)g

Step-by-step explanation:

Amount of last week's rain = g inches

this week = 5% decrease on last week's amount

5% of last week's amount = 5/100 × g = 0.05g

∴ This week's amount of rain = 0.05g decrease

∴ Amount of rain this week = (Amount of rain last week) - 0.05g

∴ Amount of rain this week = g - 0.05g

This can be simplified by factorizing the common term "g"

g - 0.05g = g(1 - 0.05) = 0.95g
