Answer: The answer is 32%
Step-by-step explanation: <u>10% is the wrong answer!</u> I see everybody saying 10% but it is wrong let me show you:
I linked the table down below and by doing simple math like addition and subtraction I filled in the missing numbers on the 2-way table. So what you have to do to get the percentage is take 38% (which is the total of of no-canoe and no-trek students) and divide it by 120 (the overall total). This will get you a long decimal of 0.31666667, but then you are going to multiply the decimal by 100; 0.31666667*100, to get 31.666667 which is your percentage and we will round it up to <u>32%</u>
good luck
PS. I took the test and got it right
- Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
So firstly, remember that <u>perpendicular lines have slopes that are negative reciprocals to each other.</u> To find the slope of L1, the easiest method is to convert it into slope-intercept form.
Firstly, subtract 5x on both sides of the equation:
Next, divide both sides of the equation by 8 and your slope-intercept form will be
Now looking at this equation, the slope appears to be -5/8 for L1. <u>Since L2 is perpendicular, this means that the slope of L2 is 8/5.</u>
Next, to find the y-intercept, put the slope into the m variable and put (10,10) into the x and y placeholders to solve for b as such:
<u>Putting it together, your equation is , with m = 8/5 and b = -6.</u>
Next, to find the sum you first need to convert -6 so that it has a denominator of 5. To do this, multiply -6 by 5/5 as such:
Next, add the numerators together:
<u>Your final answer is -22/5.</u>
