Iasked 5 times already analyze the following statement: marcus notices that he runs faster in the mornings rather than the evenings. is the statement an example of correlation or causation? correlation causation no relationship not enough info

Causation bc at night you've done more during the day so ur more tired whereas in the morning you've been refreshened and have more energy

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
