A new string is chosen and knotted with all the other strings to create a second row. This process is repeated until there are enough rows to make a bracelet to fit around your friend's wrist. Are the number of knots proportional to the number of rows? Explain your reasoning.

Yes, the number of knots is proportional to the number of rows.

Step-by-step explanation:

The number of knots is proportional to the number of rows, because whenever there is a new row then it implies that there is new knot.

Meaning, as the number of rows increases, the number or knots increases. This is a proportional relationship.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
