In her science class, Chelsea predicted how fast a toy car would be moving after traveling for 5 seconds down a 45 degree slope. Chelsea calculated that the toy car's speed would be 37.8 meters per second. When she used a radar gun to clock the speed of the toy car, she saw that it was actually 34.0 meters per second. What was the percent error in Chelsea's calculation​

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

c - they will have the same distribution

this is the only one that could make sense. : )
