## A group of students would like to know how well the value of coins in a bag can be predicted

A group of students would like to know how well the value of coins in a bag can be predicted based on their weight. They collected the following data. Weight (grams) 32.7 96.9 93.8 65.4 65.4 79.7 69.3 112.1 Value $0.63 $3.22 $2.10 $2.17 $2.14 $2.03 $1.76 $3.19 For the bags of coins, what is the correlation coefficient, r , between “weight” and “value”? Use technology, and round your answer to the nearest hundredth. +/-

Earth orbits the Sun because there is a

Gravitational pull from the sun on the earth. The earth is pulled toward the sun, rather than going off in a straight line

Gravitational pull from the sun on the earth. The sun pulls the earth in the direction of the Earth’s orbital path

Gravitational push from the sun on the Earth. The sun pushes the Earth away so it does not crash into the sun

Strong magnetic interaction between the sun and the Earth. The gravitational interaction between the sun and the Earth is small
