The psychiatrist to whom she is referred finds that Sandy's thinking and speech is often fragmented and incoherent. In addition, Sandy has an unreasonable fear that someone is "out to get her" and consequently trusts no one. Her condition is most indicative of:
schizophrenia

Her condition is most indicative of:

schizophrenia  (  she heard a voice commanding her to warn other people that eating is harmful)         and               chase mani  (Sandy has an unreasonable fear that someone is "out to get her")

Explanation:

 3.0 × 10¹¹ RBC's    (or)      3E11 RBC's

Solution:

Step 1: Convert mm³ into L;

As,

                                            1 mm³  =  1.0 × 10⁻⁶ Liters

So,

                                         0.1 mm³  =  X  Liters

Solving for X,

                       X  =  (0.1 mm³ × 1.0 × 10⁻⁶ Liters) ÷ 1 mm³

                       X  =  1.0 × 10⁻⁷ Liters

Step 2: Calculate No. of RBC's in 5 Liter Blood:

As given

                        1.0 × 10⁻⁷ Liters Blood contains  =  6000 RBC's

So,

                         5.0 Liters of Blood will contain  =  X  RBC's

Solving for X,

                      X  =  (5.0 Liters × 6000 RBC's) ÷ 1.0 × 10⁻⁷ Liters

                      X  =  3.0 × 10¹¹ RBC's

Or,

                     X  =  3E11 RBC's
