Use for questions 37-40: The 100-meter dash times in the girls track meet were normally distributed with a mean of 13 seconds and a standard deviation of 0.3 seconds. Lana finished the race in 13.2 seconds. If 84 other girls ran in the event, approximately how many runners did she beat?

answer:   c ?

step-by-step explanation:

x = 3 ± √(5+y)

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
