the height of 3-year-old boys is approximately normally distributed. Duncan and Shane are 3 year old boys. Duncan is 32.0 inches tall and is in the 32nd percentile. Shane is 34.0 inches tall and is at the 62nd percentile. Which is the closest to the mean

Duncan height is closest to the mean

Step-by-step explanation:

From the question we are told that

  Given that the height of 3-year-old boys is approximately normally distributed then the mean will be the

Hence comparing Duncan height which is in the percentile and Shane height which is in the   percentile with the mean height which is in the

i.e

and

We see that  Duncan height is closest to the mean

c. 4 and 1/2 pounds is the answer! : )

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
