You’ve observed the following returns on Crash-n-Burn Computer’s stock over the past five years: 8 percent, −15 percent, 19 perc
sattari [20]

Answer:

a). Arithmetic average return=12.80%

b). The variance of the company's returns=116.2

c). Standard deviation=10.78

Explanation:

a). The arithmetic average return can be expressed as;

Arithmetic average return=Sum of returns/Number of returns

where;

Sum of returns=8%+(-15%)+19%+31%+21%=64

Number of returns=5

replacing;

Arithmetic average return=64/5=12.80%

b). Variance of the company's returns

Step 1: Write down formula for variance

Variance=∑(Xi-X)²/n-1

where;

Xi=term in data set

X=sample mean

∑=sum

n=sample size

Step 2: write down each data set

X1=8%, X2=-15%, X3=19%, X4=31%, X5=21%

Step 3: Subtract the mean from each data set

Take the absolute value of each data

X1-X=8-12.8=-4.8

X2-X=15-12.8=2.2

X3-X=19-12.8=6.2

X4-X=31-12.8=18.2

X5-X=21-12.8=8.2

Step 4: Square each result and sum

∑(Xi-X)²=4.8²+2.2²+6.2²+18.2²+8.2²=464.8

Step 5: Divide by n-1

n=number of data points=5

n-1=5-1=4

∑(Xi-X)²/n-1=464.8/4=116.2

The variance of the company's returns=116.2

c). Standard deviation=√variance=√116.2

Standard deviation=10.78

Order: 20,000 units heparin IV in 250 mL to infuse at 25 units/kg/hr. Client weighs 184 lb. How many units per hour will the cli
miv72 [106K]

Answer:

The client will receive 2086.5 units per hour.

Explanation:

This question can be solved by rules of three:

Order

20,000 units heparin IV in 250 mL to infuse at 25 units/kg/hr.

So the number of units per hour that the client will receive is 25 multiplied by his weight, in kilograms.

Client weighs 184 lb.

We have to make the conversion of lb to kg.

Each lb is 0.4536 kg.

So the client weight 184*0.4536 = 83.46kg.

How many units per hour will the client receive?

83.46*25 = 2086.5.

The client will receive 2086.5 units per hour.
