1. Find the slope of the graph: 5/3

2. Find the slope of the graph: 4/3

3. Find the slope of the graph: undefined

4. Elyse has $18 on a gift card that she can use to rent movies online. The graph at the fight shows the amount of money remaining on her gift card based on the number of movies she rents. Find the unit rage of the graph and describe what it means in the context of the situation: 3, for every movie she looses $3.

5. Draw two different triangles on the graph that can be used to find the slope. Then explain how the triangles are related.
1, Both triangles have a slope of 1.

6. Explain wether or not the two triangles below could lie on the same line. No, 18 divided by 9 is 2 but 10 divided by 9 is not 2!

7. Draw two different triangles that could lie on a line with a slope of six. draw two triangles, one bigger than the other. On the smaller one write 6 & 1 and on the bigger one write 12 & 2

8. Find the slope of the line that passes through (12,6) and (-8, -4). 1/2

9. Find the slope of the line that passes through (10,8) and (9,13). -5

10. Find the slope of the line that passes through (2, -20) and (1,-20). 0

Plz which expression is equivalent to the expression below?

Listed below are time intervals (min) between eruptions of a geyser. assume that the "recent" times are within the past few years, the "past" times are from around 20 years ago, and that the two samples are independent simple random samples selected from normally distributed populations. do not assume that the population standard deviations are equal. does it appear that the mean time interval has changed? is the conclusion affected by whether the significance level is 0.10 or 0.01? recent 78 90 90 79 57 101 62 87 71 87 81 84 57 80 74 103 62 past 88 89 93 94 65 85 85 92 87 91 89 91 follow the steps of hypothesis testing, including identifying the alternative and null hypothesis, calculating the test statistic, finding the p-value, and making a conclusions about the null hypothesis and a final conclusion that addresses the original claim. use a significance level of 0.10. is the conclusion affected by whether the significance level is 0.10 or 0.01? answer choices below: a) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.01 but is not rejected when the significance level is 0.10. b) no, the conclusion is not affected by the significance level because h0 is not rejected regardless of whether a significance level of 0.10 or 0.01 is used. c) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.10 but is not rejected when the significance level is 0.01. d) no, the conclusion is not affected by the significance level because h0 is rejected regardless of whether a significance level of 0.10 or 0.01 is used.
