= table shows a hot air balloon's height h, in feet, during a descent at various times t, in seconds.
denpristay [2]

Answer:

A. Slope is -12 feet per second

B. Yes, it is constant.

<u>Skills needed: Linear Equations, Substitution and Division</u>

Step-by-step explanation:

1) Solving Part A (we need to find the slope):

  • The slope is \frac{y_2-y_1}{x_2-x_1} --> y_1, y_2, x_1, and x_2 are all values from the table. We know that the left column is the x-values, and the right column is the y-values as that is the conventional way of depicting them.

2) Using the y-values of 1150 and 1090, and their corresponding x-values (5 and 10 respectively), we can get the slope:

- \frac{y_2-y_1}{x_2-x_1} ==> \frac{1090-1150}{10-5} ==> 1090-1150=-60, 10-5=5 ==> \frac{-60}{5}

\frac{-60}{5} =-12, so the slope is -12.

==================================================================

1) Part B (analysis)

We can see that no matter what 2 y-values and their corresponding x values we use, the slope always is the same. This means that the rate of change is constant.

Which table shows the correct methods used to justify the solution steps?
EleoNora [17]

Answer:

x = 8

Step-by-step explanation:

Step 1 : Simplify the equation

3(x-5) + 7x = 65

3x - 15 + 7x = 65

Step 2 : Make x the subject

3x + 7x = 65 + 15

10x = 80

x = 80/10

x = 8

A 95% confidence interval for a population proportion was constructed using a sample proportion from a random sample. Which of t
liraira [26]

Answer:

All but last statement are correct.

Step-by-step explanation:

  • <em>If we were to use a 90% confidence level, the confidence interval from the same data would produce an interval wider than the 95% confidence interval.</em>

True. Confidence interval gets wider as the confidence level decreases.  

  • <em>The sample proportion must lie in the 95% confidence interval. </em>

True. Confidence interval is constructed around sample mean.

  • <em>There is a 95% chance that the 95% confidence interval actually contains the population proportion.</em>

True. Constructing 95%. confidence interval for a population proportion using a sample proportion from a random sample means the same as the above statement.

  • <em>We don't know if the 95% confidence interval actually does or doesn't contain the population proportion</em>

True. There is 95% chance that confidence interval contains population proportion and 5% chance that it does not.

  • <em>The population proportion must lie in the 95% confidence interval</em>

False. There is 95% chance that population proportion lies in the confidence interval.
