The answer is k=-1.........
Answer:
See explanation below
Step-by-step explanation:
We need to define the null hypothesis and the alternative hypothesis.
The null hypothesis is the hypothesis that states that the population results are actually what they claimed to be.
So, in this case, the null hypothesis (H₀) would be:<u> P(student buys a hard copy) = 0.60 P(student prints book from the web) = 0.25, P(student reads book online) = 0.15</u>
The alternate hypothesis states that the results were not the expected ones, in this case, any alternate hypothesis with different probabilities of any of the three cases will do.
<u>Hₐ= The percentages of students for any of the three cases is different (either greater or lower)</u>

1. At 
2. At 
The average rate of change is
Answer:
10
Step-by-step explanation:
Compare the given y = 10x to the standard form y = kx. Obviously k must be 10.
