The width of the confidence interval is twice the margin of error. The lower bound of the confidence interval is the observed score minus the margin of error;
We have to calculate the total weight of the three samples. After that we have to choose the correct answer. Weight of those three samples is: 0.170 grams, 0.204 grams and 2.300 grams. We simply have to find the sum of those weights: 0.170 g + 0.204 g + 2.300 g = 2.674 g. Answer: <span>C. 2.674 grams.</span>
Answer:
![4\times 10^7](https://tex.z-dn.net/?f=4%5Ctimes%2010%5E7)
Step-by-step explanation:
The given number,
38,332,521,
For writing the number as the product of a single digit and an exponent of 10,
We need to move decimal left side 7 times,
Thus, the exponent of 10 in the resultant number is 7,
Also, after shifting the decimal left side 7 times the resultant number is 3.8332521,
i.e. ![38332521=3.8332521\times 10^7\approx 4\times 10^7](https://tex.z-dn.net/?f=38332521%3D3.8332521%5Ctimes%2010%5E7%5Capprox%204%5Ctimes%2010%5E7)
