The volume of a cube depends on the length of its sides. This can be written in function nation as v(s). What is the best interp
PSYCHO15rus [73]

Alright, lets get started.

We have given that volume of cube depends on the lenght of side.

In cube we know that each side is of similar size.

Suppose the side lenght of cube is a, the volume of that cube will be a^3.

We have given in question notation of volume V(s).

V(3) = 27

Which shows the lenght of side of cube is 3 and the volume of cube is 27, which satisfies the formula also.

3 ^3 = 27 the volume given

So, the best interpretation of V(3) = 27 is the lenght of the cube side is 3 and the volume of the cube is 27. : Answer

Hope it will help :)

A social psychologist predicted that ratings of an individual’s social desirability would be influenced by their physical attrac
marshall27 [118]

Answer:

It is stated in the query that the more attractive the individual, the higher their rank of desirability.

Step-by-step explanation:

This means that we should conclude that the alternative explanation of "higher degree of desire contributes to higher levels of social attractiveness"

In the event of a null hypothesis, we will believe that the degree of attractiveness has no impact on the score of cultural desirability.

(1) Null hypothesis:- The level of attraction does not have an impact on the rating of social desirability.

(2) Alternate hypothesis:- The level of attraction has a positive effect on the ranking of social desirability.

(3) The error of Type I is characterized as the rejection of the true null hypothesis. Therefore, in this case, the type I mistake would be that "the level of attraction has a positive effect on the rating of social desirability while the level of attraction does not have an impact on the rating of social desirability."

(4) The error of type II is characterized as the failure to reject the false null hypothesis. Thus, in this situation, the Type II error would be that "the level of attraction has no impact on the rating of social desirability while the real level of attraction has a positive effect on the rating of social desirability."

(5) We know that the likelihood of having a Form I error is equal to the degree of significance (in percent terms). The significance level, in this case, is 0.05, so the likelihood of making a form I error is 0.05 * 100=5 percent.

Therefore, there is a 5 percent risk of making a Type I mistake.

2 pm to 6pm is 4 hours

10 feet - 2 feet = 8 feet

 8 feet / 4 hours = 2 feet per hour
