Dylan and Tiffany each constructed a two-color spinner. Dylan spun his spinner 3 times and calculated that the
relative frequency of his spinner landing on blue (0.67) and on red (0.33). Tiffany spun her spinner 200 times
and calculated the relative probability of her spinner landing on blue (0.60) and on red (0.40).
How can Dylan's and Tiffany's calculations be used to evaluate the fairness of the two spinners?

Answers

Answer:

You can calculate the likeliness of the spinner landing on blue or red as the  more spins you have the more accurate the results would be. In this case after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance landing on blue.

The weights (in ounces) of several moon rocks are shown in the table. Find the mean, median, and mode of the weights. Moon Rock Weights (ounces) 2.2 2.2 3.2 2.4 2.8 3.4 2.6 3.0 2.5

Answers

Answer:

the mode that repeats the most is 2.2 becuase to find it you need to find the number that repeats the most in the table. To find the median you add all the numbers and divide them to get the answer that is 2.7 for the mean but to find the median you need to order them from least to greatest and the answer you get for the median is 2.6 so hopefully that is the correct answer for all of them.

Answers

Answer: 80

Step-by-step explanation:

100% - 90% = 10% > 0.1

800 / 0.1 = 80

80 Cards = 10% | 800 x 0.9 = 800, + 80 = 880

The answer is 80 because 10% of 800 is 80

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches

Answers

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

The gasoline consumption of a bus is 30l/100km and of a car is 9l/100km. To go on a 250 km trip, 30 people can either go by car with 5 people in each car or take one bus for all 30 people. Which method of transportation uses less gasoline, and how much less?

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Case 1: Bus

Consumption/ 100Km= 301

and, for 250 Km= 301 /100 x 250

                          = 751

Case 2: Car

Total = 80 people

Total cars= 30/5 = 6

Consumption/ 100Km= 91

and, for 250 Km= 91 /100 x 250

                          = 22.51

Consumption by 6 cars = 6 x 22.51 = 1351

Difference between Gasoline Consumption = 1351-751 = 601
