Answer:
10.375
Step-by-step explanation:
To find the mean, you need to add up all of the numbers and then divide by the amount of numbers.
4 + 5 + 8 + 12 + 12 + 13 + 14 + 15 = 83
83 ÷ 8 = 10.375
Answer:
x= {2+ i}/2 , {2- i}/2 = C
Step-by-step explanation:
4x² - 8x +5 = 0
using quadratic formula
x= {-b±√b²-4ac}/2a
x= [-(-8)±√(-8)²-4(4)(5)] /2x4 = [8±√64-80]/8= [8±√-16]/8 = {8±4 i}/8
x= {8+4 i}/8 , {8-4 i}/8
x=4 {2+ i}/8 , {2- i}/8
4 divides 8
x= {2+ i}/2 , {2- i}/2 = c
