1 Determine whether the given ordered pair is a solution to the system of equations. 8xy =4 x+8y =2 Ordered pair: (4,0) 2 In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 37% with a margin of error of 2.2%. Describe the conclusion about p using an absolute value inequality. 3. Describe all numbers x that are at a distance of 2 from the number 9. Express this using absolute value notation. The answer field below uses the symbol mode option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbol mode will automatically convert that to . In the same way, if you type in > and then =, the symbol mode will automatically convert that to . The answer field below uses the symbolic entry option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbolic entry option will automatically convert that to . In the same way, if you type in > and then =, the symbolic entry option will automatically convert that to . sure to use decimal numbers in your answer (such as using 0.40 for 40%). 4 Find the x- and y-intercepts of the graph of the function f(x)=2|x3|+4. Enter your answers as points, (a,b). Enter the x-intercepts in order of increasing x-value. If there are no x-intercepts, enter NA in both answer areas. x-intercepts: y-intercept
