Answer:

D is the closest, but look at the work below.

Step-by-step explanation:

First let's write what we know.

We have 8 equal sections, they are:

                            1

                     5          2

                 1                     1

                     4          3

                            1

We need to find the probability the pointer will land on an odd-numbered section.

Now we find how many odd numbered sections there are.

                           <em> </em><u><em>1</em></u>

                     <u><em>5</em></u>          2

                 <u><em>1</em></u><u><em> </em></u>                    <em><u>1</u></em>

                     4          <u><em>3</em></u>

                            <u><em>1</em></u>

There are 6 odd numbered sections.

So you have a 6 in 8 chance of spinning an odd number or 6/8.

6/8 can be reduced to 3/4 or .75 05 75%

This doesn't match any of your answers you gave, so double check the question or the answers. D is the closest, but this is a very clear solution and I am wondering if there is an oops somewhere.

If an intravenous solution containing 123 mg of a drug substance in each 250-mL bottle is to be administered at the rate of 200
12345 [234]

Answer:

24.39mL of the solution would be given per hour.

Step-by-step explanation:

This problem can be solved by direct rule of three, in which there are a direct relationship between the measures, which means that the rule of three is a cross multiplication.

The first step to solve this problem is to see how many mg of the solution is administered per hour.

Each minute, 200 ug are administered. 1mg has 1000ug, so

1mg - 1000 ug

xmg - 200 ug

1000x = 200

x = \frac{200}{1000}

x = 0.2mg

In each minute, 0.2 mg are administered. Each hour has 60 minutes. How many mg are administered in 60 minutes?

1 minute - 0.2 mg

60 minutes - x mg

x = 60*0.2

x = 12mg

In an hour, 12 mg of the drug is administered. In 250 mL, there is 123 mg of the drug. How many ml are there in 12 mg of the drug.

123mg - 250mL

12 mg - xmL

123x = 250*12

x = \frac{250*12}{123}

x = 24.39mL

24.39mL of the solution would be given per hour.

PLEASE HELP ASAP!!!
Dafna1 [17]

Answer:

Step-by-step explanation:

Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula

A(t)=P(1+\frac{r}{n})^{(n)(t)}

Here's what we have:

The amount after a certain time that she has in the bank is 4672.12; that's A(t).

The interest rate in decimal form is .18; that's r.

The number of times the interest compounds is 12; that's n

and the time that the money is invested is 3.5 years; that's t.

Filling all that into the formula:

4672.12=P(1+\frac{.18}{12})^{(12)(3.5)} Simplifying it down a bit:

4672.12=P(1.015)^{42} Raise 1.015 to the 42nd power to get

4672.12 = P(1.868847115) and divide to get P alone:

P = 2500.00

She invested $2500.00 initially.
