Answers

Answer 1

Answer:

100% = 168

1% = 1.68

17.5% =

1.68 x 17.5 = 29.4

168 + 29.4 = 197.4 which is the increased amount in pounds

HHHEEELLLPPP!!!! MY ENTIRE SUMMER DEPENDS ON THIS!!IF YOU CAN’T LEGITIMATELY ANSWER, DON’T BOTHER EVEN TRYING.Test to see how many boxes of Lucky Chocolate Oat Crunch need to be purchased to collect all eight dinosaurs. Use the spinner provided to simulate the purchase of the cereal boxes. Each time the spinner is spun, it represents the purchase of one cereal box. As you spin, you will need to keep track of your results. You will use the results to compute the experimental probability, which you will compare with the theoretical probability. Use the spinner below to determine how many boxes of cereal you might need to purchase to collect all eight dinosaurs. Continue until the spinner has landed on each dinosaur once. Be sure to stop spinning once the spinner has landed on each dinosaur one time. Each number on this spinner represents a different dinosaur. You need to complete the simulation three times. That is, after each dinosaur has been spun one time, record your results. Then, create a new chart for the next set of results. When you are finished, you will have three sets of data that will most likely not match. (ALREADY COMPLETED THIS PART, THE CHARTS ARE BELOW)Use all three sets of data to answer the following questions in complete sentences. For this exercise, the probabilities refer to the probability of getting any one dinosaur when making any one purchase. You do not need to determine the probability of the compound event of getting all eight of the dinosaurs. Make sure to have all three simulations done to help you answer these questions in the writer's box:(NEED HELP WITH THIS. ANSWERED A FEW ALREADY, NEED HELP WITH THE ONES SHOWN)1. How does the number of spins correlate to the number of boxes of cereal that you would need to purchase?2. What was the experimental probability for EACH dinosaur from Trial 1? Trial 2? Trial 3?3. How does the experimental probability of getting each dinosaur differ from the theoretical probability? Here, you are comparing the experimental vs. theoretical probability of getting each type of dinosaur in a single purchase. In other words, you are determining the probability for a single event, not a compound event.4. If someone bought eight boxes of cereal and got all eight dinosaurs, would you be surprised? Why or why not?5. How did the experimental probabilities change between the trials?6. What are the advantages of using a simulation versus actually buying boxes of cereal?

The expression 2b+8 factored is

Answers

we can see we can divide both by 2
remember revers distributive
ab+ac=a(b+c)

so
2b=2(b)
8=2(4)
2b+8=2(b)+2(4)=2(b+4)

the factored form is 2(b+4)

What is 9.375 Rounded to the nearest hundredth

Answers

Note the hundredth place value (underlined and bolded):

9.375

Look at the number to the right of the hundredth place value. It is a 5. Because you round up if the number is 5 or greater, you round up in this case (you round down if it is 4 or less).

9.375 rounded to the nearest hundredth is 9.38

9.375 Rounded to the nearest hundred is

9.38 that's your answer Hope this helps :)
