Answer
Step-by-step explanation:
Okay so add 276 two times, then divide that answer by 400.
Answer:
roots : 4, -4, i, -i
Step-by-step explanation:
This gets a bit tricky.
We have to substitude x^2 as u in this problem.
Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get
u^2 - 15u - 16 = 0
( u - 16) (u + 1)
U = 16
U = -1
<em>This is not the end of the problem. </em>
Now we have to substitute x^2 back to u.
x^2 = 16 --> we get the roots 4 and -4
x^2 = -1 --> we get the roots i and -i
tadah!
Min = 31
med = 44
max = 57
lq = 38
uq = 51
iqr = 13
The answer to this is 3 bc 47*2=94
100-94=6
6/2=3
