Answer:
68%
Step-by-step explanation:
<em><u>68-95-99.7% Rule:</u></em>
<em><u /></em>
This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:
- 68% of the data fall within 1 standard deviation of the mean
- 95% of the data fall within 2 standard deviation of the mean, and
- 99.7% of data falls within 3 standard deviations of the mean
Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
The equation would be
g + (g + 9) = 45
2g + 9 = 45
- 9
2g = 36
÷ 2
g = 18
18 + 9 = 27
