Sophia has an ear infection. The doctor prescribes a course of antibiotics. Sophia is told to take 500 mg doses of the antibioti
olganol [36]

Answer:

Dosage= 500 mg

Frequency= twice a day (every 12 hours)

Duration= 10 days

Number of dosage= 10*2= 20

residual drug amount after each dosage= 4.5%

We can build an equation to calculate residual drug amount:

  • d= 500*(4.5/100)*t= 22.5t, where d- is residual drug, t is number of dosage
  • After first dose residual drug amount is: d= 500*0.045= 22.5 mg
  • After second dose: d= 22.5*2= 45 mg

As per the equation, the higher the t, the greater the residual drug amount in the body.

Maximum drug will be in the body:

  • d= 20*22.5= 450 mg at the end of 10 days

Maximum drug will be in the body right after the last dose, when the amount will be:

  • 500+19*22.5= 927.5 mg

Paul [167]

Answer:

.0166

Step-by-step explanation:

Central Limit Theorem for proportions:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation \sigma_{p} = \sqrt{\frac{p(1-p)}{n}}

In this question:

n = 900, p = 0.55

What is σρˆ?

The standard deviation of the sample proportion, which is:

\sigma_{p} = \sqrt{\frac{0.55*0.45}{900}} = 0.0166

This recipe makes 8 pancakes.
Goryan [66]

Answer:

If Sanjay wants to make 24 but the recipe makes 8, then do the recipe 3 times to get 24 (8 x 3 = 24)

135 x 3 = 405

1 x 3 = 3

2 x 3 = 6

130 x 3 = 390

1 x 3 = 3

2 x 3 = 6

So Sanjay would need the following to make 24 pancakes:

405g flour

3tsp baking powder

6tbsps sugar

390mL milk

3 eggs

6tbsps oil
