Answer:
Choice D is correct
Step-by-step explanation:
The eccentricity of the conic section is 1, implying we are looking at a parabola. Parabolas are the only conic sections with an eccentricity of 1.
Next, the directrix of this parabola is located at x = 4. This implies that the parabola opens towards the left and thus the denominator of its polar equation contains a positive cosine function.
Finally, the value of k in the numerator is simply the product of the eccentricity and the absolute value of the directrix;
k = 1*4 = 4
This polar equation is given by alternative D

This is a normal distribution with the mean of 14 g/dL and a standard deviation of 1 g/dL.
For less than 13 ( 13 = mean - 1 standard deviation and less ):
16 %<span> of 200, 0.16 * 200 = </span>32 people.
For greater than 14 ( mean and greater ): 50 %<span> of 200 = </span>100 people.<span> </span>
