Identify all of the necessary assumptions for a significance test for comparing dependent means. Group of answer choices Random Samples or Random application of treatments Both sample sizes are greater than 30 or Both population distributions could be Normally Distributed Quantitative Data n is greater than or equal to 30 OR Population of Differences could be Normally distributed. At least 15 successes and 15 failures in both groups Categorical Data

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.
