Answer:
The unlimited mileage plan would save money for Lia from 410 miles onwards.
Step-by-step explanation:
Since Lia can rent a van for either $ 90 per day with unlimited mileage or $ 50 per day with 250 free miles and an extra 25 ¢ for each mile over 250, to determine for what number of miles traveled in one day would the unlimited mileage plan save Lia money, the following calculation must be performed:
90.25 - 50 = 40.25
40.25 / 0.25 = 161
161 + 250 = 411
Therefore, the unlimited mileage plan would save money for Lia from 410 miles onwards.
306 is the total cards sent by all the students in the class. Lets say x is the number of students in class, therefore each student needs to send x-1 cards (since they do not send themselves a card). So depending on your level of math, you could either take the complex way to solve it using quadratic equations, or just find the number that if multiplied by itself then subtracted, gives you 306.
===============
Complex way
So a = 1, b = -1, c=-306
using the quadratic equation:
2.5% of the boxes have weights that are more than 2 standard deviations below the mean.
<h3>What is
empirical rule?</h3>
The empirical rule states that for a normal distribution, 95% of the values are within two standard deviations from the mean.
Given mean of 16 ounces and a standard deviation of 0.5 ounces.
Hence:
95% is within 16 ± 2(0.5) = (15, 17)
number above 2 standard deviation = 5%/2 = 2.5%
2.5% of the boxes have weights that are more than 2 standard deviations below the mean.
