Hi there! I can help you! 8 + (-9) + (-2). When adding negative integers, you have to subtract. 8 - 9 is -1 and -1 - 2 is -3. You would have to start at 8 and go to the left 11 times to land on -3. The sum to the problem is -3.
<span>Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 x = 18.75 lb of water evaporated : ; Check; amt of salt remains the same, only the percentage is different, right? .05(50) = .08(50-18.75) .05(50) = .08(31.25) 2.5 = 2.5</span>
$3.15 because you multiply 4.50 by .30 because you change the percent into a decimal so you get 1.35.Now you subtract 4.50 and 1.35 because it is a discount.
Answer:
Scatter plots can be a little confusing, but all you need to do is look for an association (what direction the dots appear to be going in). Positive association resembles this / whereas negative association resembles this / flipped the other way. It could also be a curved line, which would be a nonlinear association. If it appears to have no direction at all it has no association. Other wise, all you have to do is read the data to answer the questions. e.g. for the first question find the highest score in the right side of the table and then the corresponding number in the left side. Hope this helps!
