@greenlegodude57 do you understand it?

OpenStudy (anonymous):

Upper quartile is wrong.

OpenStudy (anonymous):

Okay, may you explain a bit so I may understand how to figure that out...

OpenStudy (anonymous):

So that's your answer :)

OpenStudy (anonymous):

The table below shows the amount of money, in cents, Celine had in her savings account after different number of years: Years 2 5 1 4 6 3 Money in cents 36 972 12 324 2,916 108 What will be the amount of money, in cents, that Celine will save in 12 years?

OpenStudy (anonymous):

Sure, just gonna explain.

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

34,992 708,588 2,125,764 2,679,875

OpenStudy (anonymous):

You put the numbers in ascending order: 74,74,83,83,83,86,87,90,92,93,93,94 Plug it in here: http://www.miniwebtool.com/interquartile-range-calculator/ Lower Quartile = 83. Upper Quartile = 92.5 So it's the Upper

OpenStudy (anonymous):

Oh okay

OpenStudy (anonymous):

This is the table: 1, 12 2, 36 3, 108 4, 324 5, 972 6, 2916 Notice anything?

OpenStudy (anonymous):

Not that I can see, sorry

OpenStudy (anonymous):

The 'y' value is increasing by a multiple of 3. 12 \(\times\) 3 = 36 2, 36 36 \(\times\) 3 = 108 3, 108 Get it?

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

So now you can find out what x = 12 will be. 2916 \(\times\) 3 = 8748 7, 8748 8748 \(\times\) 3 = 26244 8, 26244 26244 \(\times\) 3 = 78732 9, 78732 78732 \(\times\) 3 = 236196 10, 236196 236196 \(\times\) 3 = 708588 11, 708588 708588 \(\times\) 3 = 2125764 12, 2125764 So your answer is 2,125,764

OpenStudy (anonymous):

Thank you so much

OpenStudy (anonymous):

I have two more that I don't understand

OpenStudy (anonymous):

Okay, shoot.

The histogram shows the temperature, in degrees Celsius, of a city (x) on different days (y): histogram has frequency 1 for interval -20 to -15, frequency is 2 for the interval -15 to -10, frequency is 3 for the interval -10 to -5, frequency is 4 for the interval -5 to 0, frequency is 8 for the interval 0 to 5, frequency is 6 for the interval 5 to 10, frequency is 5 for the interval 10 to 15, and frequency is 4 for the interval 15 to 20 Based on the histogram, which statement is correct about the shape of the histogram?

OpenStudy (anonymous):

OpenStudy (anonymous):

there's the histogram

OpenStudy (anonymous):

Based on the histogram, which statement is correct about the shape of the histogram? It is skewed to the right because of the presence of more number of days with lower temperatures than with higher temperatures. It is skewed to the left because of the presence of more number of days with lower temperatures than with higher temperatures. It is skewed to the left because of the presence of more number of days with higher temperatures than with lower temperatures. It is skewed to the right because of the presence of more number of days with higher temperatures than with lower temperatures.

OpenStudy (anonymous):

Okay, hold on.

OpenStudy (anonymous):

k

OpenStudy (anonymous):

D

OpenStudy (anonymous):

It 'skewed' to the right, meaning that there are a lot more days with higher temperatures than lower temperatures.

OpenStudy (anonymous):

okay

Rosie made a scatter plot with the following data: Number of correct answers (x) 6 2 4 7 1 9 3 8 5 Test score (y) 18 6 12 21 3 27 9 24 15 Which statement is correct about the scatter plot for the data?

OpenStudy (anonymous):

It will show a positive linear relationship between x and y. It will show a negative linear relationship between x and y. It will show a positive exponential relationship between x and y. It will show a negative exponential relationship between x and y.

OpenStudy (anonymous):

Scatter plot: 1, 3 2, 6 3, 9 4, 12 5, 15 6, 18 7, 21 8, 24 9, 27 Notice anything?

OpenStudy (anonymous):

Um, times 3?

OpenStudy (anonymous):

No +3. x increases by 1, y increases by 3. This is positive because both increase. It is also linear because x and y are being added to. So your answer is A.

OpenStudy (anonymous):

oh, geez I suck

OpenStudy (anonymous):

Lol :P Welp, that's the last?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

Okay, good luck! \(\cal\Huge\color{lime}{-Green}\)
