Answer:

2.12

Explanation:

PED = % Change in Quantity demanded / % Change in price

✔️Price when quantify demanded was 8:

Substitute Q = 8 into P = 50 - 2Q

Thus:

P = 50 - 2(8)

P = 50 - 16

P = 34

✔️Price when quantify demanded was 12:

Substitute Q = 12 into P = 50 - 2Q

Thus:

P = 50 - 2(12)

P = 50 - 24

P = 26

✔️% change in price = (old price - new price)/old price × 100

Old price = 34

New price = 26

% change in price = (34 - 26)/34 × 100 ≈ 23.53 (2 d.p)

✔️% change in quantity demanded = (old quantity - new quantity)/old quantity × 100

Old quantity = 8

New quantity = 12

% change in quanty demanded = (8-12)/12 × 100 = 50%

✔️ Elasticity (PED) = 50/23.53 = 2.12 (2 d.p)

D) Wind caused her mobile to move, and she smiled.

Explanation:

Our medulla oblongata is a neuronal mass responsible for transmitting signals between the spinal cord and the higher parts of the brain. The medulla oblongata also controls autonomic activities - involuntary body functions and actions such as heartbeat, respiration, vasodilation, coughing, sneezing, and swallowing. Notice that letter D is, out of the options, the only one that does not mention an autonomic activity. Therefore, we can choose it as the one that was NOT controlled by Heather's medulla.
