Question

I need help on this graph!! Perform the required data interpretations. 23 -26

Answer 1

Answer:  23) 40 mph

                24) yes. 3.18

                25) 44.2%

                26) 20 - 30 mph

Step-by-step explanation:

23) $\dfrac{\text{stopping distance}}{\text{speed}}\implies \dfrac{43}{20}=2.15\qquad \dfrac{79}{30}=2.63\qquad \boxed{\dfrac{126}{40}=3.15}$

24) $\dfrac{251-79}{79}=\boxed{3.18}\implies \text{Yes. It is a little more than "tripled"}$

25) $\dfrac{183-328}{328}=\large\boxed{-44.2\%}$

26)

$\large\boxed{20-30}:\quad \dfrac{79-43}{43}=83.7\%\\\\\\30-40:\quad \dfrac{126-79}{79}=59.5\%\\\\\\40-50:\quad \dfrac{183-126}{126}=45.2\%\\\\\\50-60:\quad \dfrac{251-183}{183}=37.2\%\\\\\\60-70:\quad \dfrac{328-251}{251}=30.7\%$

The largest increase is from 20 - 30 mph
