The newspaper in Haventown had a circulation of 80,000 papers in the year 2000. In 2010, the circulation was 50,000. With x = 0
2 answers:
Answer:
-3000
Explanation:
The missing number is the slope of the line.
To calculate the slope, we use the formula
Using the points (0, 80000) and (10, 50000) [<em>remember</em>, the year 2000 is at x = 0; this means the year 2010 would be at x=10] we have:
m = (50000-80000)/(10-0) = -30000/10 = -3000
The missing number, the slope, is -3000.

Answer:
H0: p ≥ 0.03 Ha: p < 0.03
Step-by-step explanation:
1) Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
2) Solution to the problem
On this case we want to test is , where:
represent the true proportion for the population of broken pieces
What we want to proof need's to be on the alternative hypothesis and the complement on the null hypothesis.
So the correct system of hypothesis for this case would be:
Null hypothesis:
Alternative hypothesis:
H0: p ≥ 0.03 Ha: p < 0.03
Answer:
is the required inequality
Step-by-step explanation:
Let the number of songs = m.
The cost of downloading 1 songs = $1.29
So, the cost of downloading 'm' songs = dollars
Since, the maximum amount she can spend on downloading songs is $20.
So, we get the inequality,
Hence, the inequality representing the situation is .
