Simplify the expression. Explain each step: 1. 3.5 + (x + 2.7) 2. (8 x k) x 4

1 answer:

8 0

In a way, you are adding like terms.
3.5 + 2.7 = 6.2, therefore making the answer 6.2 + x

The brackets can be ignored so you are really just asked 8 x 4 x k. 8 x 4 =32 so you end up with 32k

If A denotes some event, what does Upper A overbar denote? If P(A)equals0.999, what is the value of P(Upper A overbar)? Wh

meriva

Answer:

<h3>The event $P(\overline{A})$ denotes the complement of event A.</h3><h3>The value of $P(\overline{A})$ is 0.001</h3>

Step-by-step explanation:

Given that A denotes some event .

And also given that P(A)=0.999

<h3>To find the value of $P(\overline{A})$ :</h3>

Here the event $P(\overline{A})$ denotes the complement of event A Therefore $P(\overline{A})$ contains all the events that does not occur in A.

We know that the total probability is 1

So we have that

$P(A)+P(\overline{A})=1$

$P(\overline{A})=1 -P(A)$

$=1-0.999$

$=0.001$

Hence the complement of event A is $P(\overline{A})=0.001$

<h3>Therefore the value is $P(\overline{A})=0.001$ </h3>

Demerol 45mg and atropine 400mcg/ml give how much per ml to total volume to inject demerol contains 50mg/ml, atropine contains 4

OverLord2011 [107]

Answer:

Volume injected = 1.65 ml

Step-by-step explanation:

mass of Demerol =45 mg.

density of pre-filled in syringe = 50 mg/ml

Volume = 45/50 = 0.9 ml

For atropine mass = 0.3 mg

density= 400 mcg/ml [ Note : 1 mcg = 0.001 mg]

volume filled = 0.3/400(0.001) = 0.75 ml

So, the total volume filled = 0.75+0.9 = 1.65 ml
