Doctors sometimes use this formula to calculate how much medicine to give a child. A child who is 4 years old needs some medicin
AnnyKZ [126]

Answer:

A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity

Step-by-step explanation:

Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.

...

Example 2.

Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day

Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose

Answer:

Rational form:

399/100 = 3 + 99/100

Continued fraction:

[3; 1, 99]

Possible closed forms:

399/100 = 3.99

log(54)≈3.988984

8/(3 π) + π≈3.9904190

1/2 (e! + 1 + e)≈3.989551

-(sqrt(3) - 3) π≈3.983379

(14 π)/11≈3.9983906

25/(2 π)≈3.978873

(81 π)/64≈3.976078

(2 e^2)/(1 + e)≈3.974446

(π π! + 2 + π + π^2)/(3 π)≈3.988765

2 π - log(4) - 3 log(π) + 2 tan^(-1)(π)≈3.987955

2 - 1/(3 π) + (2 π)/3≈3.988291

In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product,
Vadim26 [7]

Answer: 0.2872

Step-by-step explanation:

Given : In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 260 of these people said they never did so.

i.e. n= 1000 and x= 260

⇒ Sample proportion : \hat{p}=\dfrac{260}{1000}=0.26

z-value for 95% confidence interval : z_c=1.960

Now, an upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate. :-

\hat{p}+ z_c\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

=0.26+ (1.96)\sqrt{\dfrac{0.26(1-0.26)}{1000}}

=0.26+ (1.96)(0.01387)=0.26+0.0271852=0.2871852\approx0.2872

∴ An upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate : 0.2872

What pair of points have a slope of -3/5
sergey [27]

Answer:

(5,0) and (0,3) have a slope of -3/5

Step-by-step explanation:

Here, we want to state a pair of points that have a slope of -3/5

Mathematically, we can have the slope of a straight line calculated as;

m = y2-y1/(x2-x1)

This could give points like (5,0) and (0,3)
