The long-distance calls made by the employees of a company are normally distributed with a mean of 6.3 minutes and a standard de

Sergio [31]

To solve this problem, we use the formula:

z = (x – u) / s

where z is the z score value which can be obtained from the tables, x is the sample value, u is the mean = 6.3 min, and s is the std dev = 2.2 min

at P value = 0.90, the z = 1.28, finding for x:

x = z s + u

x = 1.28 * 2.2 + 6.3

x = 9.116

at P value = 1.0, the z = 3.49, finding for x:

x = z s + u

x = 3.49 * 2.2 + 6.3

x = 13.978 ~ 14

Therefore the longest 10% calls last about 9.1 minutes to 14 minutes

Which equation represents a parabola that has a focus of (0 0) and a directrix of y = 2

mel-nik [20]

ANSWER

$x ^{2} = - 4(y - 1).$

EXPLANATION

Since the parabola has the (0, 0) and the directrix at y=2.

The equation is of the form

${(x - h)}^{2} = - 4p(y - k)$

where (h,k) is the vertex.

The vertex is half way between the directrix and the focus.

The vertex will be at (0,1)

and is the distance from the vertex to the focus which is 1.

${(x - 0)}^{2} = - 4(1)(y - 1)$

$x ^{2} = - 4(y - 1)$
