The average lethal blood concentration of morphine is estimated to be 2.5 µg/mL with a standard deviation of 0.95 µg/mL. The dat

dmitriy555 [2]

Answer:

The probability associated with the range lethal morphine blood levels is 0.9902.

Step-by-step explanation:

Let <em>X</em> = lethal blood concentration of morphine.

The random variable <em>X</em> is normally distributed with parameter <em>μ</em> = 2.5 μg/ mL and <em>σ</em> = 0.95 μg/ mL.

Compute the probability of <em>X</em> within the range 0.05 to 4.95 μg/ mL as follows:

$P(0.05$

*Use a <em>z</em>-table for the probability.

Thus, the probability associated with the range lethal morphine blood levels is 0.9902.

Find the first partial derivatives of the function. (sn = x1 + 2x2 + ... + nxn; i = 1, ..., n. give your answer only in terms of

liq [111]

Answer:

∂u/∂xi = i·cos(sn)

Step-by-step explanation:

For u = sin(v), the partial derivative of u with respect to xi is ...

∂u/∂xi = cos(v)·∂v/xi

In this case, v=sn, and ∂sn/∂xi = i, so the derivatives of interest are ...

∂u/∂xi = i·cos(sn)

A bug was running along a number line at a speed of 11 units per minute. It never changed its direction. If at 7:15 pm it was at

Minchanka [31]

Answer:

155 Units

Step-by-step explanation:

Rate of Bug (given) = 11 units PER MINUTE

It never changed direction, so it was going in positive direction (assume).

In 7:15 pm (evening), it was at Point 100,

We want the point at which it was at 7:20 pm.

7:20pm - 7:15pm = 5 minutes

So, time passed 5 minutes. It's rate is 11 units PER MINUTE, so in 5 mins:

11 * 5 = 55 units

<em>Assuming he is going in positive direction</em>, the bug will be at:

100 + 55 = <u>155 Units</u>
