Answer:
a) 
b) 
c) 
Step-by-step explanation:
<u>For the question a *</u> you need to find a polynomial of degree 3 with zeros in -3, 1 and 4.
This means that the polynomial P(x) must be zero when x = -3, x = 1 and x = 4.
Then write the polynomial in factored form.

Note that this polynomial has degree 3 and is zero at x = -3, x = 1 and x = 4.
<u>For question b, do the same procedure</u>.
Degree: 3
Zeros: -5/2, 4/5, 6.
The factors are

--------------------------------------

--------------------------------------

<u>Finally for the question c we have</u>
Degree: 5
Zeros: -3, 1, 4, -1
Multiplicity 2 in -1

--------------------------------------

You can evaluate / find
<span>8.64 x 10^6
-----------------
4.32 x 10^3
by first dividing 8.64 by 4.32 and then dividing 10^6 by 10^3:
2*10^3 (answer)

Answer: B
Step-by-step explanation:because my teacher said she having trouble
P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..
A. All remaining numbers are in Q because it goes "even" left, and "odd" right.
B. Probability of it not being in Q is 1/2
