Pl wi th th is and tell me the steps plzz

Step-by-step explanation:

The mean (also called an average) is obtained by adding all the terms together then dividing the result by the number of terms in the set.

96 + 74 + 81 + 94 + 75

420/5 = 84

Mean of 7th Grade Math Exam Results: 84%

73 + 60 + 86 + 72 + 81

372/5 = 74.4

Mean of 8th Grade Math Exam Results: 74.4%

Comments: The 7th graders got, on average, almost 10% more on their exams than did the 8th graders. Also, none of the 8th graders got an A, whereas two 7th graders got an A on their exam. My inference is that 8th grade math is harder than 7th grade math, so that is why the scores are lower.

I'm always happy to help :)

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
