Answer with explanation:</h2>
Given : The proportion of U.S. employers were likely to require higher employee contributions for health care coverage in 2009 : p=0.52
Sample size : n= 800
Significance level : ![\alpha=1-0.95=0.05](https://tex.z-dn.net/?f=%5Calpha%3D1-0.95%3D0.05)
Critical value : ![z_{\alpha/2}=1.96](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D1.96)
Margin of error : ![E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=E%3Dz_%7B%5Calpha%2F2%7D%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
![\\\\\Rightarrow\ E=(1.96)\sqrt{\dfrac{0.52(1-0.52)}{800}}=0.03462050259\approx0.03](https://tex.z-dn.net/?f=%5C%5C%5C%5C%5CRightarrow%5C%20E%3D%281.96%29%5Csqrt%7B%5Cdfrac%7B0.52%281-0.52%29%7D%7B800%7D%7D%3D0.03462050259%5Capprox0.03)
The 95% confidence interval for the proportion of companies likely to require higher employee contributions for health care coverage in 2009 will be :_
![p\pm E\\\\=0.52\pm0.03=(0.52-0.03,0.52+0.03)=(0.49,\ 0.55)](https://tex.z-dn.net/?f=p%5Cpm%20E%5C%5C%5C%5C%3D0.52%5Cpm0.03%3D%280.52-0.03%2C0.52%2B0.03%29%3D%280.49%2C%5C%200.55%29)
Step-by-step explanation:
2y - 4x + 6 = 0
2y = 4x - 6
y = 4x/2 - 6/2
y = 2x - 3

Answer:
0.0726mL
Step-by-step explanation:
Let's find the answer by using the following formula:
(subcutaneous dose)=(milliliters of the injection)*(drug concentration)/(child weight)
Using the given data we have:
(0.01mg/kg)=(milliliters of the injection)*(1mg/mL)/(16lbs)
milliliters of the injection=(0.01mg/kg)*(16lbs)/(1mg/mL)
Notice that the data has different units so:
1kg=2.20462lbs then:
16lbs*(1kg/2.20462lbs)=7.25748kg
Using the above relation we have:
milliliters of the injection=(0.01mg/kg)*(7.25748kg)/(1mg/mL)
milliliters of the injection=0.0726mL
