Answer:
Two complex roots.
Step-by-step explanation:
F(x)=2x^4 +5x^3 - x^2 +6x-1
is a polynomial in x of degree 4.
Hence F(x) has 4 roots. There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.
Use remainder theorem to find the roots of the polynomial.
F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0
There is a change of sign in F from 0 to 1
Thus there is a real root between 0 and 1.
Similarly by trial and error let us find other real root.
F(-3) = -1 and F(-4) = 94
SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.
Other two roots are complex roots since no other place F changes its sign
Step-by-step explanation:
<h3> cookbooks : novels </h3><h3> 2 : 11 </h3><h3> So 6 : 33 </h3>
<h3> cookbooks : reference books </h3><h3> 3 : 4 </h3><h3> So 6 : 8 </h3>
novels : cookbooks : reference books
<h3> 33 : 6 : 8 </h3>
The answer is both sets of statistics give the same information:
First, find the mean: 2 • 5 = 10, 3 • 4 = 12, and 10 • 1 = 10
10 + 12 + 10 = 32
Ten dots altogether : 32 ÷ 10 = 3.2
Mean = 3.2
Second, find the median: 2, 2, 2, 2, 2, 3, 3, 3, 3, 10
2, 2, 2, 2, <em>2, 3,</em> 3, 3, 3, 10
2 + 3 = 5
5 / 2 = 2.5
Median - 2.5
