I hope its correct..Cause Even I am not so good at maths..I tried
Answer: 
Step-by-step explanation:
By definition, the slope of the line is described as "Rate of change".
You need to use the following formula to calcualte the slope of the line;
In this case you know that the line passes through these two points: (8, -10) and (-6, 14).
Then, you can say that:
Knowing these values, you can substitute them into the formula for calculate the slope of a line:
Finally, you must evaluate in order to find the slope of this line. You get that this is:
Answer:
1. False
2. True
3. True
4. True
5. False
Step-by-step explanation:
1. False - they sell 3 cases in 20 min as shown in the table
2. True - If they sold 3 cases in 20 min and 6 cases in 40 min, then they would sell 9 cases in an hour, and 12 cases in 1 hour and 20 min
3. True - Building off of our answer in 2, student council would have sold 15 cases in 1 hour and 40 min, and 18 in 2 hours
4. True - In 40 min, student council sold 6 cases, and in 2 hours, 18 cases, so in 2 hours and 40 min, they would have sold 24 cases
5. False - In one hour - 9 cases. In 2 hours - 18 cases. In 3 hours - 27. And in 20 min - 3 cases, so they would sell 30 cases in 3 hours and 20 min.
Answer:
(a) 36.36%
(b) 0.36%
(c) 0.06%
Step-by-step explanation:
Given that the time intervals measured with a stopwatch have an uncertainty of about 0.2 s.
We want to know what is the percent uncertainty of a hand-timed measurement of:
(a) 5.5 s
Percentage = (0.2/5.5) × 100
≈ 36.36%
(b) 55 s
Percentage = (0.2/55)×100
≈ 0.36%
(c) 5.5 min
5.5 min = 5.5 × 60 s
= 330 s
Percentage = (0.2/330)×100
≈ 0.06%
