The heights of North American women are nor-mally distributed with a mean of 64 inches and a standard deviation of 2 inches. a.
serious [3.7K]

Answer:

0.1587

Step-by-step explanation:

Given the following :

Mean (m) of distribution = 64 inches

Standard deviation (sd) of distribution = 2 inches

Probability that a randomly selected woman is taller than 66 inches

For a normal distribution :

Z - score = (x - mean) / standard deviation

Where x = 66

P(X > 66) = P( Z > (66 - 64) / 2)

P(X > 66) = P(Z > (2 /2)

P(X > 66) = P(Z > 1)

P(Z > 1) = 1 - P(Z ≤ 1)

P(Z ≤ 1) = 0.8413 ( from z distribution table)

1 - P(Z ≤ 1) = 1 - 0.8413

= 0.1587

Explain why x^2 + y^2 -6x +10y = -34 is NOT a circle. What is it?
kenny6666 [7]

Answer:

(See explanation for further details)

Step-by-step explanation:

The expression is transformed into its standard form:

x^{2} + y^{2} - 6\cdot x + 10\cdot y + 34 = 0

x^{2} - 6\cdot x + 9 + y^{2} + 10\cdot y + 25 = 0

(x-3)^{2} + (y+5)^{2} = 0

The function does not represent a circle, as radius is a positive number.
