Answer:
x4 = 8
Step-by-step explanation:
To find the mean, add the values and divide by the number of values.
mean = (x1 + x2 + x3 + x4)/4
(3 + 12 + 7 + x4)/4 = 8
x4 + 22 = 32
x4 = 10
127 is already in the simplest form. It can be written as 1.714286 in decimal form
8 x 6 = 42 add two zeros so 4200
19 divides by 217.4 equals to 0.08739
