A. steve received the following test scores: 78, 83, and 79. find steve’s test average.  b. six packages had weights of 2 lb, 5 lb, 7 lb, 5 lb, 9 lb, and 8 lb. what’s the average weight of the packages?

Average =total sum of all the numbers / number of items in the set.

In other words, to find the average, add up all of the numbers in the set, and then divide by however many items you have.

A.

Test scores: 78,83 and 79

average =(78+83+79)/3 = 80

B.

weights : 2 lb, 5 lb, 7 lb, 5 lb, 9 lb, and 8 lb.

average = (2 lb+ 5 lb+ 7 lb+ 5 lb+ 9 lb+ +8 lb)/6 = 36/6 = 6lb

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
