Answer:
Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.
Step-by-step explanation:
Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.
We want to find the area between the z-scores of -3 and 3.
The <u>Empirical Rule</u> tells us that 99.7% of the data lies <em>within three standard deviations</em> under the normal curve.
Therefore, the <u>area</u> between <em>-3 < z < 3</em> is about <u>.997</u>, or around <u>99.7%</u>.
Answer:
One pound costs 1.26, two costs 1.47, three costs 1.68, and four costs 1.89. So we calculate how much it increases in each pound.
1.26 + 21 = 1.47
1.47 + 21 = 1.68
1.68 + 21 = 1.89
1.89 + 21 = 2.10
2.10 + 21 = 2.31
2.31 + 21 = 2.52
2.52 + 21 = 2.73
8 pounds cost: 2.73
So I pay $ 2.73 for 8 pounds.
Simple addition. The answer is 11.
