To answer your questions:
1. The aim of the person who threw the darts in the picture can be determined by analyzing the precision and accuracy of the throws.
- If the person's aim was both precise and accurate, then statement A is true.
- If the person's aim was precise but not accurate, then statement B is true.
- If the person's aim was accurate but not precise, then statement C is true.
- If the person's aim was neither precise nor accurate, then statement D is true.
To determine which statement is correct, it would be helpful to see the picture and evaluate the position of the darts relative to the intended target.
2. The measurement of the volume of a liquid given as 40 mL has two significant figures.
To determine the number of significant figures, you should follow these rules:
- Non-zero digits are always considered significant.
- Zeroes between non-zero digits are considered significant.
- Leading zeros (zeros at the beginning of a number) are not considered significant.
- Trailing zeros (zeros at the end of a number) are significant if there is a decimal point present.
In this case, the number 40 has two significant figures because it doesn't have a decimal point and the zero is not significant.
3. To calculate the area of a rectangular room that is 14.10 m wide by 15.0 m long with the appropriate number of significant figures, we multiply the width and length.
- The width, 14.10 m, has four significant figures.
- The length, 15.0 m, has three significant figures.
When multiplying or dividing measurements, the result should have the same number of significant figures as the measurement with the fewest significant figures. Thus, the answer should have three significant figures.
Calculating the area: 14.10 m * 15.0 m = 211.5 m^2
Therefore, the correct answer is B: 211.5 m^2.
