(I) Alpha+Beta= 2
Alpha-Beta= √D/|a|= √10
Alpha^2 - Beta^2
=(Alpha+Beta) (Alpha-Beta)
= 2* √10
= 2√10
To determine the answers to this item, we are to arranged the given data points in increasing order. The arrangement would then be,
97,163, 169, 175, 184, 199
The lower quartile is the median of the lower half of the data points. In this case, 97, 163, 169. The median is equal to 163
The upper quartile is the median of the upper half of the data points. In this case, 175, 184, 199. The median is equal to 184.
Hence, the aswers to this item is that lower quartile is equal to 163 and upper quartile is equal to 184. The first option.
Answer:
<h2>33</h2>
Step-by-step explanation:
Given the average low temperature by month in Nashville is represented by the function f(x)=-1.4x² + 19x +1.7, where x is the month, the average rate of change is expressed as d[f(x)]/dx = 2(1.4x) + 19
d[f(x)]/dx = 2.8x + 19
Since the number of months between March and August is 5 months and x is in months, hence we will substitute x = 5 into the resulting function to get the average rate of change from March to August as shown;
d[f(x)]/dx at x = 5
= 2.8(5)+ 19
= 14 + 19
= 33
<em>Hence the average rate of change from March to August is 33</em>
Answer:
Step-by-step explanation:
The basic model for this growth is the exponential function: y = a(b)^c, where a is the initial value, b is the growth rate and c is the time.
Here we have P = fish population = (2 fish)(3)^t
