In the U.S., from 2004-2015, the correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y, is r =0.97. Describe what this means about the relationship between the data plan size and the number of text messages sent in the U.S.

Answer options:
- There is no correlation between the size of the data plan and the number of text messages in the US.
- There is a weak positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong negative linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.

I'd appreciate if you included an explanation, but an answer is fine.

Answer 1

Answer:

D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.

Step-by-step explanation:

We have r = 0.97

Correlation coefficients whose magnitude are between 0.9 and 1.0 indicate variables which can be considered very highly correlated (as per below table)r = (0.9, 1.0) very highly correlated. r = (0.7, 0.9)  highly correlated. r = (0.5, 0.7)  moderately correlated. r = (0.3, 0.5)  low correlation. r = (0, 0.3)  little to no correlation.

Same applies to negative side

Correct choice is

D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.

To explain it in very simple way, consider a linear equation:

y = mx + b

Number of text messages is the linear function of the data plan. r = 0.97 shows this relationship is almost a perfect line with positive slope.

Answer 2

- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent is your answer

it sells the same gadgets for $9, it will sell 900 per month. To the nearest whole
number, how many gadgets could be sold per month, if the price was $12?

Answers

(5, 1050), (9, 900), (12, y)
For linear relation,
(y-1050)/(12-5) = (900-1050)/(9-5)
Solve for y,
y = 787.5

Jack, Alex and Amir jumped a total of 12.69 m in a long

jump competition.

Alex jumped exactly 200 cm further than Jack.

Amir jumped exactly 2,000 mm further than Alex.

What distance did they all jump?

Give your answers in metres.​

Answers

Answer:

Step-by-step explanation:

The distances they jumped were

x,y,z

y=x+2

z=x+2+2=x+4

x+y+z=12.69

x+x+2+x+4=12.69

3x+6=12.69

3x=6.69

x=2.23

So Jack jumped 2.23m, Alex jumped 4.23m, and Amir jumped 6.23m.

Hello There!

The problem states that the angles are complementary angles

Complementary angles are angles that have measures that add up to equal 90

So given one of the angles we can find the missing angle by subtracting the known angle from 90

90 - 81 = 9

so we can conclude that the measure of angle 2 is 9
