To determine: The models, which appears to be a better fit for the data and explain which model would you choose to make predictions beyond 2020
Hawaii is having a linear model and Idaho population is having exponential or logistic
Given Information:
The table is defined,
Time (years) | Hawaii (thousands) | Ldaho (thousands) |
1980 | 965 | 944 |
1990 | 1108 | 1007 |
2000 | 1212 | 1294 |
2010 | 1360 | 1568 |
Calculation:
Consider the given information,
The linear model seems to be a good fit for Hawaii as most points appear to be on the line which means that there is almost a constant change in population.
An exponential or a logistic model seems to be appropriate for Idaho since there is a sudden increase in population for the same year intervals which is from 1990 to 2000.
Hence, Hawaii is having a linear model and Idaho population is having exponential or logistic

- Consider the region below f(x) = (11-x), above the x-axis, and between x = 0 and x = 11. Let x; be the midpoint of the ith subinterval. Complete parts a. and b. below. a. Approximate the area of the region using eleven rectangles. Use the midpoints of each subinterval for the heights of the rectangles. The area is approximately square units. (Type an integer or decimal.)arrow_forwardRama/Shutterstock.com Romaset/Shutterstock.com The power station has three different hydroelectric turbines, each with a known (and unique) power function that gives the amount of electric power generated as a function of the water flow arriving at the turbine. The incoming water can be apportioned in different volumes to each turbine, so the goal of this project is to determine how to distribute water among the turbines to give the maximum total energy production for any rate of flow. Using experimental evidence and Bernoulli's equation, the following quadratic models were determined for the power output of each turbine, along with the allowable flows of operation: 6 KW₁ = (-18.89 +0.1277Q1-4.08.10 Q) (170 - 1.6 · 10¯*Q) KW2 = (-24.51 +0.1358Q2-4.69-10 Q¹²) (170 — 1.6 · 10¯*Q) KW3 = (-27.02 +0.1380Q3 -3.84-10-5Q) (170 - 1.6-10-ºQ) where 250 Q1 <1110, 250 Q2 <1110, 250 <3 < 1225 Qi = flow through turbine i in cubic feet per second KW = power generated by turbine i in kilowattsarrow_forwardHello!
