The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic. which weights are within 2 standard deviations of the mean? check all that apply.8.4 lbs8.9 lbs9.5 lbs9.8 lbs10.4 lbs10.9 lbs

The weights within this range are:

8.9

9.5

9.8

10.4

Step-by-step explanation:

The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:

9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)

8.5 ≤ x ≤ 10.5

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
