Explain how looking at a line can tell us whether its slope is negative, positive, undefined, or zero. Choose the correct answer below.
O A. A line with a negative slope decreases from left to right, while a line with a positive slope increases from left to right. A line with a slope of zero is a vertical line, and a line with undefined slope is a horizontal line.
O B. A line with a negative slope increases from left to right, while a line with a positive slope decreases from left to right. A line with a slope of zero is a horizontal line, and a line with undefined slope is a vertical line
OC. A line with a negative slope increases from left to right, while a line with a positive slope decreases from left to right. A line with a slope of zero is a vertical line, and a line with horizontal slope is a vertical line
OD. A line with a negative slope decreases from left to right, while a line with a positive slope increases from left to right. A line with a slope of zero is a horizontal line, and a line with undefined slope is a vertical line

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
