The answer is No because the sample is not representative of the whole population. The standard deviation of the sample is not a good estimate of the variation of the salaries of the TV personalities in general because a single sample is not counted as a whole. Standard Deviation is a quantity that is calculated to indicate the extent of deviation of the population or group as a whole. Standard deviation also represented by the symbol σ means sigma in Greek letter or s in Latin letter. It is also the measurement of a set of data values that are used to quantify the amount of variation.
Their could be 14 people who order the deluxe and 18 people who get regular meals
Answer:
The concentration of a drug in an organ at any time t (in seconds) is given by s 0.25t - 15(1 - e-t/60) if osts 20 | 15e-t/60 – 10e-(t - 20)/60 if t> 20 where c(t) is measured in milligrams per cubic centimeter (mg/cm3). (a) What is the initial concentration of the drug in the organ? 0 mg/cm3 (b) What is the concentration of the drug in the organ after 14 sec? (Round your answer to three decimal places.) x mg/cm3 38 (c) What is the concentration of the drug in the organ after 40 sec? (Round your answer to three decimal places.) mg/cm3 Need Help? | Read It
You first have to set up the two equations. Y is equal to the total number of gallons in a tank and x is equal to the number of hours the tanks are filling.
Since the two equations both equal y I can make them equal each other. I then solved for x as you see and got -4.
Once I found my x value I now needed to find my y. You only needed to chose one equation to solve for y, so I decided to do the first one. I plugged in -4 where my x value currently was and solved for y. I got 2.
If you have any questions please comment!! Hope this helps!!
