When Ryan runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 2 seconds. If Ryan were to run
36 practice trials of the 400 meter dash, how many of those trials would be between
62 and 65 seconds, to the nearest whole number?

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2
