If complex coefficients are allowed, the answer is 3.
If the polynomial must have real coefficients, then each complex root comes as a pair of complex conjugate roots.
Root -5 is real, so that is 1 root, and degree 1.
Root 1 + 4i is complex, so it must come with its complex conjugate, 1 - 4i. This adds 2 roots to the polynomial, and now we're up to degree 3.
Root -4i is also complex. It also must come with its complex conjugate, 4i. That adds two more roots, and the degree is 5.
Answer: The least possible degree is 5 with real coefficients.
Divide 100 to 56 = 56/100= 0.56 then you wanna times it by 50 so then it would be.56x50=28
Step-by-step explanation:
2 2 5 9 and 12
mode= 2
median = 5
Range : 12- 2 =10
Mean: 2+2+ 5+ 9+ 12=30
30÷ 5 = 6
Answer:
1.5
Step-by-step explanation:
The mean is 2.5
1-2.5=1.5
5-2.5=2.5 This is the absolute distance from the mean
3-2.5=0.5
1-2.5=1.5
1.5+2.5+0.5+1.5=6
6/4=1.5
