Unit 8 Day 16 Ch. 11-13 Partner Test

This is a partner test. I am assessing your understanding level of the material we have covered.

The test should be done with only the assistance of your notes, class slide decks or the posted Ch. 11-13 slide decks and your partner. You should not request or accept the assistance of a friend, family member or neighbor. Submitting answers and/or work done by or with the assistance of someone else is grounds for an Academic Integrity write-up.

After reading the text above, select your response.

To be clear, selecting "No" does not free you of the consequences of your actions. Rather, it means I will disable your test until we can talk one-on-one so that you better understand before proceeding.

The famous Rose Bowl Parade features floats that are decorated with roses and other flowers from around the world. Based on past experience, one float decorator found that
10% of the bundles of roses delivered will not open in time for the parade,
20% of the bundles of roses delivered will have bugs on them and be unusable,
60% of the bundles of roses will turn out to be beautiful,
the rest of the bundles of roses delivered will bloom too early and then discolor
What percent of the bundles of roses will bloom too early and then discolor?

You will use a list of random numbers to conduct a simulation to estimate the number of bundles of roses the float decorator will need to purchase to have 10 good bundles of roses for decorating the float'.

How will you represent the bundles using numbers on a random number list?
Explain clearly - this is the component.

4

Using the information in the previous question, what is the response variable?

4

You how would you conduct a simulation to estimate the number of bundles of roses the float decorator will need to purchase to have 10 good bundles of roses for decorating the float?

Explain your method clearly for conducting 10 trials using the TI-84 calculator.
It needs to be clear enough so someone from an Algebra 2 class could conduct the simulation.

You DO NOT need to actually conduct the trials, just explain how you would do it 👌

4

Imagine that you've conducted a simulation to estimate the number of bundles of roses the float decorator will need to purchase to have 10 good bundles of roses for decorating the float, you found that an average of 18 bundles were required.

Based on the summary above, give your conclusion.

Hint: what did the simulation suggest?

Many clubs have to find creative ways to do fund raising at Alamo Heights High School.
One popular way to raise money is the selling of Bubble Teas.

During Bubble Tea sales at lunch, student leaders have determined that:
26% of AHHS students prefer jasmine milk tea,
23% prefer taro milk tea,
18% prefer strawberry milk tea,
21% prefer chocolate milk tea,
and the remainder prefer plain milk tea.
