ANSWER
circle
EXPLANATION
The given equation is
To determine the type of conic, we analyze the coefficient and sign of the quadratic terms.
If the coefficient of the quadratic terms are equal and have the same sign,then the conic is a circle.
If the coefficient of the quadratic terms are equal and have opposite signs,then the conic is a hyperbola.
If the coefficient of the quadratic terms are not equal and have the same sign,then the conic is an ellipse.
Since the coefficients are all 1 and the signs are positive, the given conic is a circle.

Answer:
(a) Minimum red blood cells 5.744 million cells per micro liter
(b) Maximum red blood cells 5.068 million cells per micro liter.
Step-by-step explanation:
Z-score formula is =
Z-score =
The value of z-score is 0.61 so then x will be;
x = 5.744
The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.
Z-score =
The value of z-score is 0.14 so then x will be;
x = 5.068
The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.
