Answer:
2995
Step-by-step explanation:
The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set
1127
1482
2995
3009
3250
3250
3445
3449
4000
6120
rearranging the data sets from the least to the highest
the middle number of the data sets is 3250
the middle number between the smallest number and the median of the data set is 2995

Answer:
2 complex roots
Step-by-step explanation:
The function f(x)=x^5+4x^3−5x can be factored as follows:
f(x)=x(x^4+4x^2−5). One root, a real root, is zero.
That leaves g(x) = x^4+4x^2−5. Substitute p = x^2, obtaining p^2 + 4p - 5 = 0. This factors as follows: (p+5)(p-1) = 0. Thus, p = -5 and p = 1.
Recalling that p = x^2, we have -5 = x^2 and +1 = x^2. The latter yields x = 1 and x = -1. The former yields +i√5 and =i√5.
Thus, the given poly has 3 real zeros: -1, 1 and 0. Due to the imaginary roots shown above, this means that this poly has 2 complex roots.
