Tao Motor company conducted rolling bench tests to determine the maximum speed of their latest 50cc scooter. They found that the maximum speed had a normal distribution with mean = 46 km/hr and standard deviation = 2.5. Use the Emperical Rule (68/95/99.7) to answer the following question. What percentage of these scooters have a maximum speed greater than 51 km/hr

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

1/3 + 1/5 = 8/15.

step-by-step explanation:
