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.

Digiron [165]

Answer:

About 11.299 hours.

Step-by-step explanation:

To solve this problem, you can set up an equation to model the decay of the medicine. Let's call the time that medicine has been in the body x.

(1-0.0595)^x=0.5

0.9405^x=0.5

Taking the log x of both sides, you get

x=\log_{0.9405} 0.5

x\approx 11.299 hours. Hope this helps!

Then, you only need to replace the value of the angle in the function, to obtain the requested area.

<span>A(Θ) = 16 sin Θ • (cos Θ + 1).

Θ = 60°

A(</span>60°<span>) = 16 sin(</span><span>60°) * [cos(</span><span>60°) + 1 ] = 16 * (√3) / 2 * [1/2 + 1] = 8(√3) * 3/2 = 12√3 ≈ 20.79
