Two state parks, Elm Grove and Cathedral Rock, each recorded the number of visitors to the park each day for 15 days. The parks
made line plots from the data recorded.
What statement about the two plots’ distributions is true?
There is no overlap between the two distributions.
The degree of overlap between the two distributions is high.
The degree of overlap between the two distributions is moderate.
The degree of overlap between the two distributions is low.
Two line plots with the same scale and interval, from zero to six hundred, with tick marks every fifty units. The plots are stacked vertically for comparison. Values appear as x marks above the line. Each plot has fourteen data values. Upper plot is labeled Elm Grove. Upper plot data values are one x mark above fifty, two x marks above one hundred, three x marks above one hundred fifty, four x marks above two hundred, three x marks above two hundred fifty, one x mark above three hundred, and one x mark above three hundred fifty. Lower plot is labeled Cathedral Rock. Lower plot data values are one mark above three hundred, one makr above three hundred fifty, two marks above four hundred, three marks above four hundred fifty, four marks above five hundred, three marks above five hundred fifty, and one mark above six hundred.

Answer:
<em>4.7 years</em>
Step-by-step explanation:
Distance of planet from Earth = 1.3 parsec
We know that 1 parsec = 3.26 light years
And a light year is the distance traveled by light in time period of 1 year.
So, Distance of planet from Earth = 1.3 3.26 = 4.24 light years
Given that, the person travels at a speed equal to 90% of the light speed.
To travel to the planet from Earth, Light takes 4.24 years.
To travel the distance , at a speed
light takes time of 4.24 years.
To travel the distance , at a speed
, the person takes time:
So, the twin on Earth ages by <em>4.7 years.</em>
