Answer:

<h2><u>#1: </u></h2>

The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:  

4 lbs / $3  = 1lb / x     = cross-multiply  

4x = 3   =  divide by 4  

x = 3/4 dollars = $.75 per pound

----------------------------------------------------  

<h2><u>#2: </u></h2>

The point (8,6) means that 8 lbs. of potatoes = $6.

---------------------------------------------------------------------------------------

Hope this helps!

Answer:

A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)

 

The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:

4 lbs / $3  = 1lb / x       cross-multiply

4x = 3      divide by 4

x = 3/4 dollars = $.75 per pound

 

The point (8,6) means that 8 lbs. of potatoes = $6.

A nonprofit organization sent mailing labels along with a request for donations to a random sample of 75,000 potential donors on
Law Incorporation [45]

Answer:

Check the explanation

Step-by-step explanation:

The null and alternative hypotheses in symbols and words are as follows:

: p ≤ 0.06 (There has been no change in the contribution rate due to addition of the mailing labels)

: p > 0.06 (The addition of the mailing labels has increased the contribution rate)

Test Statistics

The following information is provided: The sample size is N = 75000, the number of favorable cases is X = 5625, and the sample

The z-statistic is computed as follows:

- P_0 (1 -

Test statistic z = 17.297

P-value

P-value corresponding to z = 17.297 for a two tailed test is obtained using standard normal table.

p-value = 0.0000

90% Confidence Interval Calculation

Kindly check the attached image below.

Conclusion

Since p-value = 0.0000 < α = 0.05, we reject null hypothesis .

At 0.05 significance level, there is enough evidence to conclude that the addition of the mailing labels has increased the contribution rate.

Since the 90% confidence interval (0.073, 0.077) does not contain the hypothesized value 0.06, the result is significant and we reject null hypothesis.

In other words, at 0.10 significance level, there is enough evidence to conclude that the addition of the mailing labels has increased the contribution rate.
