@hero Which is the conclusion of this statement? If a and b are both negative then a • b = |a| • |b|. A. If a and b are both negative, a • b = |a| • |b|. B. a • b = |a| • |b| if a and b are both negative. C. a and b are both negative. D. a • b = |a| • |b|. <--- Again two parts, and the conclusion part is D because a and b are both negative. It says it inside the sentence. :) Right? 0_0
Correct
It says "If both a and b are negative..." The key word is "If", but a • b = |a| • |b| is in the conclusion portion of the statement.
So therefore, what you chose for the answer choice is correct.
@hero Theo finds a large container of batteries in a basement. He randomly selects and tests 14 of the batteries and finds that 4 of them do not work. There are 76 batteries in the container. Which is the best prediction for the number of batteries that will not work? A. 5 B. 18 C. 22 D. 29 76/14=5 5x4=20 22 is the closest, to 20. You'll have to explain it to me if I did it wrong. This one confused me. :)
So...C?
Yes C. You can also set up a proportion: \[\frac{4}{14} = \frac{x}{76}\] and solve for x to figure it out.
Each fraction in the proportion represents \[\frac{\text{no of batteries that don't work}}{\text{total number of batteries tested}}\]
