Kisachek [45]
The mean of the data ser is 33.8
Answer:
x=62 and y=59
Step-by-step explanation:
59+59=118
180-118=62=x
180-62=118
118/2=59=y
The answer is <span>x4 + 2x2 + 2,
proof
if a is a (real) is a root of </span><span>x4 + 2x2 + 2, so
a4 +a2 +2 =0, it is impossible, because a4>0, a2>0 and 2>0
</span>a4 +a2 +2 must be >0, so x4 + 2x2 + 2 doesnt have real roots
