Answer:
Ann would need 3 h to complete the remainder of the Job.
Step-by-step explanation:
Step 1.
The "speed" that each girl has to do the work is determined as:
- Tina: , it means that Tina complete one twelveth of the job each hour.
- Ann: , it means the Ann completes one eighth of the job each hour.
Step 2.
The amount of work done by Tina in 9 hours, is obtain multiplying by the "speed" calculated in step 1:
Amount of work done= . It means that <em>Tina completes two thirds of the work in 9 h.</em>
Step 3.
The remaining job is calculated as . It means that <em>still remains is one third of the job to be completed</em>.
Step 4.
The time required for Ann to complete the job is calculated dividing the remaining of the job by the "speed" of Ann to do the job.
. It means that <em>Ann would complete the job in another 3 hours</em>.
Answer:
Step-by-step explanation:
.
a. Yolanda only wins if the cup lands upright.
From the experimental data we see that the probability of winning is 5 out of 50, or
10%. Therefore, if Yolanda plays 10 times she can expect to win 10% of 10 times = 1
time. She will lose 9 times. (Note: Ten trials is a very small number of trials, so we should not be surprised if Yolanda’s results are very different from the percentages
produced by the longer experiment.)
b. If Yolanda wins 1 time and plays 10 times, she will have spent $10 to play and won
back only $5, so she would have less money at the end of 10 games.
