Alocal university produced a study in which it chose 1000 students to participate. the study asked each student to write down the number of hours spent studying in a one week period. which element of experiment design is known to be a part of this study?

The correct answer is REPLICATION

Step-by-step explanation:

Replication is important for the support of the study. It is when a procedure repeats using the same methods, different subjects and experiments. It also involves the application of the theory of the study in new situations in order to generalize it. Replication assurances the validation and reliable of the results, generalize them

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
