A supervisor finds the mean number of miles that the employees in a department live from work. He finds x=29 and s=3.6 . Which s

qwelly [4]

Answer:

Option 3 is right

z37 is between 2 and 3 standard deviations of the mean.

Step-by-step explanation:

Let X be a random variable which represents the mean number of miles that the employees in a department live from work

X is normal (N(29,3.6)

WE have to find Z score for X

Z = $\frac{x-29}{3.6}$

=2.22

i.e. 37 is 2.22 std deviations from the mean.

In other words, z37 is between 2 and 3 standard deviations of the mean.

If f(x)=4-x^2 and g(x) =6x which expression is equivalent to (g-f)(3)

MArishka [77]

Answer:

-18

Step-by-step explanation:

Given:

f(x)=4-x^2 and g(x) =6x

h(3) = (g-f)(3)

= 6x - (4x^2)

= 6*3 -(4*3^2)

= 18 - 4*9

= -18

Solve this question g(3)=

Virty [35]

Answer:

Step-by-step explanation:

Where g is 3, the value is 4.

To find the values, the number in the parentheses tells you the x coordinate of the point. Find the point that corresponds to the coordinate to see where it lines up on the y-axis. The answer is the y-value.

So, another way of looking at is x(3). Where x is 3, y is 4.
