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?
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.

State whether the following is reasonable or not. Explain your answer. Josefina gave away 130% of her stamp collection.
Answer:
Hey there!
That wouldn't be possible.
130% of something is more than the total amount.
For example, if she had 100 stamps, and gave away 130%, she would have -30 stamps, which is unreasonable.

Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.
What are the values a, b, and c in the following quadratic equation?
−6x2 − 8x + 12 = 0
a = −6, b = −8, c = 12
a = 6, b = 8, c = 12
a = 8, b = 12, c = 0
a = −8, b = 12, c = 0
Answer: A!
Step-by-step explanation: The quadratic formula is ax2+bx+c, so you just plug in and see which ones go with the equation, a=-6 (-6x2) b=-8 (+-8 or -8) and c=12 (+12) Hope this helps
The sum of four consecutive odd numbers is -72. What are the four numbers?
Write a let statement (or statements).
Answer:
So the four consecutive odd integers are: 51 , 53 , 55 and 57
Step-by-step explanation:
I wish i can help
Answer:
- 15, - 17, - 19, - 21
Step-by-step explanation:
let the 4 consecutive odd numbers be
n , n + 2, n + 4, n + 6 ( that is 2 between each odd number ) , then
n + n + 2 + n + 4 + n + 6 = - 72
4n + 12 = - 72 ( subtract 12 from both sides )
4n = - 84 ( divide both sides by 4 )
n = - 21 , then
n + 2 = - 21 + 2 = - 19
n + 4 = - 21 + 4 = - 17
n + 6 = - 21 + 6 = - 15
The 4 numbers are - 15, - 17, - 19, - 21

The graph relates the distance traveled by Train A, in miles, and the time taken, in hours. The table shows the distance traveled by Train B, in miles, and the time taken, in hours.
Answer:A)
Yes, the relationship is proportional.
B)
66,000 miles.
Step-by-step explanation:
A)
Yes, the graph represents a proportional relationship.
Since, A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:
y=kx
for some constant k , called the constant of proportionality .
As y=12000x hence the relationship is proportional.
B)
We calculate the equation of the graph with the help of two points on the graph namely (2,24000) and (4,48000) with the help of slope-intercept form of the line.
y=mx+c where m denotes the slope of the line and c denotes the y-intercept of the line.
Here when x=2 y=24000 and when x=4 y=48000
Hence, 24000=2x+c
and 48000=4x+c
on subtracting the above two equations we have:
m=12000 and c=0
Hence, the equation of line is y=12000x
Now the value at x=5.5 is:
y=12000×5.5=66,000
Hence, the number of miles the probe travels in 5.5. hours is 66,000 miles.
Step-by-step explanation:
After 1 year, $50,000 deposited in a savings account with simple interest had earned $2,500 in interest. What was the interest rate?
pls explain how as well if you don't mind
Answer:
5%
Step-by-step explanation:
The formula for calculating simple interest is:
Interest = Principal × Rate × Time
Where:
Interest is the amount of money earned as interest
Principal is the initial amount of money deposited
Rate is the interest rate (expressed as a decimal)
Time is the duration for which the money is invested or the time period over which interest is calculated
In this scenario, the principal amount is $50,000, and the interest earned is $2,500. The time period is given as 1 year.
We can rearrange the formula to solve for the rate:
Rate = Interest / (Principal × Time)
Plugging in the given values:
Rate = $2,500 / ($50,000 × 1)
The calculation simplifies to:
Rate = $2,500 / $50,000
Dividing $2,500 by $50,000 gives us the decimal value of the interest rate:
Rate = 0.05
To express the interest rate as a percentage, we multiply the decimal value by 100:
Rate = 0.05 × 100
Rate = 5%
Therefore, the interest rate for the savings account is 5%.
Answer:
Interest Rate = 5%
Step-by-step explanation:
Principal = $50, 000
Rate = ?
Time = 1 yr
S.I = PRT/100
2,500/1 = 50,000 × R × 1/100
50,000R = 2,500 × 100
50,000R = 250,000
50,000R/50,000 = 250,000/50,000
R = 5 %

I need help with this question, I'm not very good at math and all help is appreciated!
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

A swimming pool is being drained at a rate of 50 gallons per hour. How many milliliters per second is this? Round to the nearest tenth.
Answer: 3154.16 milliliters / second
Step-by-step explanation:
1 gallon = 3.785 liters
1 liter = 1000 milliliters.
So multiply to convert: 1 gallon x 3.785 liters/gallon x 1000 milliters/liter = 3785 milliters ; 50 gallons = 50*3785 = 189250 milliliters
1 hr = 60 seconds 50 gallons per hour = 189250 mililiters/60 seconds =3154.16 milliliters/second
result : 50 gallons per hour = 3154.16 milliliters / second
Find the mean of absolute deviation for the set of values

Find the mean of absolute deviation for the set of values
12.2, 6.8, 3.4, 8.8
I hate 7th grade math man sksksksj
(1) The mean absolute deviation for the given data set is 18.
The mean absolute deviation (MAD) is a way of measuring of data variability that is defined as the average of each data point's absolute deviation from the mean. To calculate the MAD, first compute the mean of the data set, then subtract each data point from the mean and calculate the absolute value of the result.
Here is the step-by-step process for finding the MAD for the given data set:
Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56
Subtract the mean from each data point:
108 - 56 = 52
53 - 56 = -3
47 - 56 = -9
22 - 56 = -34
56 - 56 = 0
62 - 56 = 6
Take the absolute value of each result:
|52| = 52
|-3| = 3
|-9| = 9
|-34| = 34
|0| = 0
|6| = 6
Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 18
So, the mean absolute deviation for the given data set is 18.
(2) The mean absolute deviation for the given data set is 2.7
Find the mean of the data set: ( 12.2 + 6.8 + 3.4 + 8.8 ) /4 = 7.8
Subtract the mean from each data point:
12.2 - 7.8 = 5.4
6.8 - 7.8 = - 1
3.4 - 7.8 = - 4.4
8.8 - 7.8 = 1
Take the absolute value of each result:
|4.4| = 5.4
|-1| = 1
|-4.4| = 4.4
|1| = 1
Find the average of the absolute deviations: (5.4+ 1 + 4.4 + 1) / 4 = 2.95
So, the mean absolute deviation for the given data set is 2.95.

Triangle D has been dilated to create triangle D′. Use the image to answer the question.
Answer: 4
Step-by-step explanation:
Divide the sides of triangle D' by their corresponding sides on triangle D (like 32 divided by 8 and 40 divided by 10). The answer every time is 4 which means the scale factor is 4.
Answer:
The answer is 4
Step-by-step explanation:
In triangle D the top side length is 8 and in triangle D' the top side length is 32. 32 is 4 times 8, and therefore D' was factored by a scale of 4 from D.
This can be done with each side:
8x=32 --> x=4 therefore the scale factor is 4
6x=24 --> x=4 therefore the scale factor is 4
10x=40 --> x=4 therefore the scale factor is 4
