Compute the zero of the function y(x) from the following data:

x = 0.2, 0.4, 0.6, 0.8, 1.0

y = 1.150, 0.855, 0.377, -0.266, -1.049

Use inverse interpolation with the natural cubic spline

Three point electric charges of magnitude Q1=2.0 μC, Q2= -1.0 μC, and Q3= 2.0 μC are situated in a straight line in air 10 cm apart (the negative charge is in the middle). Determine the of the force of each charge on the other two.

A tennis player hits a ball 2.0 m above the ground. The ball leaves his racquet with a speed of 16.0m/s at an angle 4.5? above the horizontal. The horizontal distance to the net is 7.0 m, and the net is 1.0 m high.

By how much?

1. Seven hundred and seventy-one distance learning students at Long Beach City College, located in Long Beach, California (part of the Los Angeles metropolitan area) responded to surveys in the 2010-11 academic year. Highlights of the summary report are listed in the table below:

1. What percent of the students surveyed do not have a computer at home?
2. About how many students in the survey live at least 16 miles from campus?
3. If the same survey were done at Great Basin College in Elko, Nevada, do you think the percentages would be the same? Why?

-What is the mass, in grams of 37.0 mL of a liquid if its density is 0.20 g/mL?

-An average marching speed is 6.10 nautical miles in 1.00 hours. what would this speed be in units of furlongs per year? 1 furlong = 201.2m - 1.000 nautical mile = 6076 ft

-The speed of sound is 719 miles per 1.00 hours. what is the speed in units of kilometers per day?

-An aquarium measures 110 cm by 55.0 cm by 38.5 cm. what is the volume in units of cubic feet?

-A sample of the element copper has a mass of 28.827 grams. in units of mL, what will be the volume of this sample at 25 degrees celcius.

-To extend a length of 1.00 inches, 2.54 x 10 (to 8th power) average sized atoms would have to be placed in a straight line. How many atoms placed in a straught line would be required to form a line from earth to the moon? distance between the two is 363,104 km.

You are interested in studying the relationship between a home’s selling price and various features of the home (this is called a hedonic price analysis). You estimate the following regression equation, in thousands of dollars:
  
(house price) ̂=175+12bedroom+.8square_footage - 2.5distance

Where bedroom measures the number of bedrooms in the house, square_footage is the house’s square footage, measured in hundreds (e.g. 2,200 square foot house would enter the regression as 22), and distance is the distance from downtown, measured in miles.

a. Do the signs of the coefficients match your a priori expectations? Explain why or why not based on your intuition.

b. Suppose you are a realtor. Use the regression results to estimate the value of a client’s home with the following characteristics: 3,200 square feet; 4 bedrooms; located 6 miles from downtown.
  
c. How would your estimate change if the client decided to add a 200 square-foot bedroom?

****PLEASE include bell shaped curve

The airlines industry measures fuel efficiency by calculating how many miles one seat can travel, whether occupied or not, on one gallon of jet fuel. The following data show the fuel economy, in miles per seat for 17 randomly selected flights on Delta and United. Assume the two population variances for fuel efficiency for the two airline are equal.

Delta .   

United

a. Conduct a the 95% confidence interval estimate of the population?

b. Perform a hypothesis test using α = .05 to determine if the average fuel efficiency  differs between the two airlines.

c. Determine the p-value and interpret the results.

1. An engineer collected the data below showing the speed, s, of a Toyota Camry and its average miles per gallon, M

a. Plot the data above, treating speed as the independent variabl (x). What type of relation, linear or quadratic, appears to exist between speed and miles per gallon?

b. Based on your response above, find either a linear or a quadratic model that describes the relationship between the two variables.

c. Use your model to predict the mpg of a Toyota Camry that is travelling 63 mph

d. Does this model have a maximum value? if so, what is it? if the model does not have a maximum value, find the y-intercept. Does this intercept make sense in the context of the problem
