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.

To ship a package, Company 1 charges $10 for the first pound and 0.45 for each additional pound. Company 2 charges $14 for the first pound and 0.30 for each additional pound.

What is the equation for "p", the number of pounds it would take for the cost of the two shipping companies to be the same?

Answers

Answer:

answer is on the bottom

Step-by-step explanation:

Company 1: y=0.45x+10

company 2: y=0.30x+14

To find when they are both the same, put an equal sign and solve:

0.45x+10=0.30x+14

         -10             -10

0.45x=0.30x+4

Answers

Answer: 8,700

Step-by-step explanation:

lets say you have 500 animals, and you decide to get another 500, but you decide that you want an extra 500, and then your kid says that they want another 500 animals. You now have 2000 animals, but you also need 4000 chickens so you now have 6000 animals. Then you need 900 pounds of animal food, but 900 pounds is weird so you get an extra 100 to make your total 1000. But now you need 800 dogs so you now have 2800 animals.

4000 + (500 x 4) + 900 + 100 + 800 = 8,700

Answer:

The answer would be 8700

5.906 x 10^8

2.81 x 10^9

2.81 x 10^1

Answers

Answer:

5.906 x 10^9

Step-by-step explanation:

(6.25 x 10^9) − (3.44 x 10^8).

step 1: make the exponents have common value

Move decimal point of 3.44 to the left once and add 1 to it's exponents.

that is 3.44 x10^8 becomes 0.344 x 10^9

= 6.25 x 10^9 - 3.44 x 10^8

= 6.25 x 10^9 - 0.344 x 10^9

step 2: bring out the common factor 10^9 since the exponents are the same.

Also, subtract the decimal numbers.

= (6.25 -0.344) 10^9

6.25 - 0.344 = 5.906

Therefore, the result is 5.906 x 10^9.

Answer is A. 5.906 X 10^9

What is the measure of 1 if 1 is (4x - 4) and 2 is (4x)?

What is the measure of 1 if 1 is (4x - 4) and 2 is (4x)?

Answers

Since the graph given to us is a straight line we know that the value of it is 180° since the value of a straight line is always 180°. Now we have to solve for x and to do that we add the 2 values given to us and set it equal to 180°.

4x-4+4x=180

Now we combine the like terms on the left side of the equation.

8x-4=180

Now we have to add the 4 to both sides.

8x=184

Now to get the x by itself (find the value of x) we have to divide the 8 on both sides.

x=23

Now that we have found x we can plug it back into the equation for number 1 [(4x-4)] and solve to find the value of number 1.

4(23)-4=88

Answer: 88°

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.


Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside


Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

B.
The function will become quadratic.

C.
The y-intercept will change.

D.
The second population will increase less rapidly.

Answers

Answer:

C

Step-by-step explanation:

First, we have to find the equation that will give the rabbit population as a function of time and the initial population.

The equation we need turns out to be Population = a0 x 3y  where a0 is the initial population and y is the number of years,

To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.  

You can now find the difference in the number of rabbits at year 3 for the different starting populations.

Describing that distance in such tiny units (such as millimeters) is ridiculous. Yes, 5 Km is the same as 5,000,000 mm, but I can't picture what 5,000,000 of anything really looks like.

To find what percent of 200 is 120, substitute the values into the percentage formula:

\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)

Therefore, 120 is 60% of 200.
