Cindy needs to buy 8 packs of invitations.
Hey! So, you know she bought two clipboards. You're going to want to add 2.23 and 2.23 together, which is 4.46. Sheila only bought one notebook, so you simply add 4.46 and 0.58 together, which is 5.05. But, wait! She paid with a 10 dollar bill. Now, we have to take 5.05 out of 10.00, which is 4.95. Now, our answer is going to be $4.95 in change. I hope I helped! :)
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>
Answer:
4) 5
Step-by-step explanation:
3x-x+2=12
First, you combine similar terms, so 3x-x which is 2x.
Second, you subtract 2 on both sides which is going to give you 2x=10.
Finally, you divide by 2 on both sides, so the final answer is going to be x=5.
