Answer:

A and C

Step-by-step explanation:

The meaning of an event being independent is that one event doesn't effect the probability of they other event happening. So B is wrong because whether yo sleep or not can affect whether you dream or not and D is wrong because you earning and allowance is based off whether you do your chores or not.

Answer:

C. 3.2\times 10^{1}

Step-by-step explanation:

d_r = Diameter of a red blood cell = 0.0008\ \text{cm}

d_w = Diameter of a whooping cough virus = 2.5\times 10^{-5}\ \text{cm}

Ratio of the diameter of the red blood cell to the diameter of the whooping cough virus

\dfrac{d_r}{d_w}=\dfrac{0.0008}{2.5\times 10^{-5}}=\dfrac{0.0008}{25\times 10^{-6}}=\dfrac{0.0008\times 10^6}{25}\\\Rightarrow \dfrac{d_r}{d_w}=\dfrac{800}{25}\\\Rightarrow \dfrac{d_r}{d_w}=32=3.2\times 10^{1}

The required ratio is 3.2\times 10^{1}.
