Which is the most ethical response if an experiment fails to confirm a hypothesis?
miv72 [106K]
In this circumstance one should revise the hypothesis and develop a new experiment to test it.An example could be the theory of Agraham Gottloeb Werner that all rocks were precipitated from water including not just sedimentary rocks but also volcanic, plutonic and metamorphic rocks. The more the earth was studied, especially by James Hutton in Scotland, the more it became obvious that granites for example were deposited in a molten state, thus disproving that hypothesis or theory.

Jade wants to stop for coffee on her way to school. the distance from jade's house to the coffee shop is 3 miles more than twice
Serga [27]

The total distance from jade's house to school is 5 times the distance from the coffee shop to her school =  7.5 miles

Distance is the overall movement of an object without any regard to path. we will outline distance as to how a lot ground an object has protected regardless of its starting or finishing point.

Equation;

Let the distance between coffee shop and school = X

Distance from Jade's house to coffee shop = 3 miles +2x

Total distance from Jade's house to school = 5*X

∴ the total distance = house to coffee shop + coffee shop to school

                        ⇒    5X =  (3 + 2X + X)

                        ⇒     5X = ( 3 +3X)

                         ⇒     2X = 3

                          ⇒      X = 1.5 miles

Therefore,

            Distance = house to school = 5 * 1.5 = 7.5 miles

                               coffee shop to school = 1.5 miles

                               house to coffee shop = 3 + 2*1.5 = 6 miles

Hence, The total distance from jade's house to school is 5 times the distance from the coffee shop to her school =  7.5 miles
