Jerick's Math Blog Post

Hello Everyone !
I would like to welcome you to my MATH BLOG POST
yesterday my classmates and I were assigned quetions from the math book

My question was from 2.2 number #18

Determine the mean of each set of numbers. Express your answers to the nearest hundreth, if necessary.

a) 0, -4.5, -8.2, 0.4, -7.6, 3.5, -0.2
b) 6.3, -2.2, 14.9, -4.8, -5.3, 1.6

To determine the mean ,
all you do is add up all the numbers and divide by how many number there are

ANSWERS
a.
0+(-4.5) = -4.5
-4.5 + - 8.2 = -12.7
-12.7 + 0.4 = -12.3
-12.3 + -7.6 = -19.9
-19.9 + 3.5 = -16.4
-16.4 + -0.2 = -16.6
-16.6/ 7 = -2.37

b.
6.3+ (-2.2) = 4.1
4.1+14.9= 19
19+ (-4.8)= 15.1
15.1+ (-5.3)= 9.8
9.8+ 1.6= 10.4
10.4/ 6 = 1.73
