Answer:

average of the Sophmores = 117.8

Explanation:

given data

group of college students = 90

average for group = 113

Freshmans  = 40

average score = 107

solution

we get here total of group points for all people is

total of group points =  90 × 113 = 10170

and

here Freshman came from group

Freshman came = 40 × 107 = 4280

so

Sophmores  is =  10170  - 4280  = 5890

so

average of the Sophmores is

average of the Sophmores = \frac{5890}{90-40}  

average of the Sophmores = 117.8

Which sentence is punctuated correctly? A. My friend, Greg, likes to bake cookies for the people in the office. B. My friend, Gr
Fiesta28 [93]

Answer:

The correct answer is letter A. My friend, Greg, likes to bake cookies for the people in the office.

Explanation:

What we have in this sentence is an appositive, a word or phrase immediately following and renaming another word or phase. Our appositive here is "Greg", which is renaming the noun "friend". Since "Greg" is only giving additional but not essential information, it could easily be removed from the sentence. Notice how the sentence would still make sense: " My friend likes to bake cookies for the people in the office." Since this appositive is not a restrictive one, it should be framed by commas. That is why the best option is letter A.
