Answer:

The price of the kilogram of cookies is $ 1.8

Step-by-step explanation:

Call x the price of the kilogram of candy and call y the price of kilogram of cookies

Then we know that

0.600x + 1.5y = 4.62

We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy

So

y = x-1.40

We solve this equation for x and then we substitute it in the first equation.

x = y + 1.40

0.60 (y +1.40) + 1.5y = 4.62\\\\0.60y + 1.5y = 4.62 - 0.84\\\\2.1y = 3.78

y = \$1.8

PilotLPTM [1.2K]

The markup value = $62.25

The mark up percentage = 15%

Step-by-step explanation:

Step 1 :

Cost price of the video game = $415

Selling price of the video game = $477.25

We need to find the mark up value and the markup percentage

Step 2 :

The markup value can be computed by taking the difference of the selling and the cost price.

Hence the markup = $477.25-$415 = $62.25

The markup percentage is computed on the cost price

so the mark up percentage =( 62.25 ÷ 415) × 100 = 15%

Step 3 :

Answer :

The markup value = $62.25

The mark up percentage = 15%

A study of 31,000 hospital admissions in New York State found that 4% of the admissions led to treatment-caused injuries. One-se
vovikov84 [41]

Answer:

Step-by-step explanation:

a) probability a person admitted to the hospital will suffer a treatment-caused injury due to negligence

P(injury) = 4%

P(negligence) = 1/4 = 0.25

We need to find probability (injury)(negligence)

P(injury) * P(negligence) = 0.04*0.25 = 0.01

b) probability a person admitted to the hospital will die from a treatment-caused injury

P(injury) = 4%

P(death) = 1/7

P(Injury) *P(death) = 0.04/7 = 0.00571

c) In the case of a negligent treatment-caused injury, what is the probability a malpractice claim will be paid

P(claim) = 1/7.5

P(payment) = 1/2

P(claim)*P(payment) = 1/7.5 * 1/2 = 0.06
