The airplane takes off 12 1/2 miles south of a city
Speed =180*3/4
=45*3
=135
135-12.5
The plane is 122.5 miles north to the city after 45 minutes

For how many weeks would the class need to have car washes to earn $5000.
nikdorinn [45]
The correct answer would be for 29 weeks.
Its because if for 4 weeks the profit is $700, divide 700 and 4 which gives you $175 per week. Then divide 5000 and 175 which gives you 28.5714286. So all you have to do is round it up to the nearest whole which gives you the answer: 29 weeks.
Hope that helps. :)

The data set below shows the temperature, in degrees Fahrenheit, of a mug of tea compared tothe time in minutes after being pour
Verizon [17]

Given the model of the Exponential Regression:

y=174.4(0.987)^x

By definition:

Residual=Observed\text{  }y\text{ }value-Predicted\text{ }y\text{ }value

You can see in the table the observed y-values (the temperature in Fahrenheit)

In order to find the Predicted y-values, you need to substitute all the x-values given in the table (the time in minutes) into the equation and then evaluate. You get:

y=174.4(0.987)^5\approx163.35y=174.4(0.987)^8\approx157.07y=174.4(0.987)^{11}\approx151.02y=174.4(0.987)^{15}\approx143.32y=174.4(0.987)^{18}\approx137.80y=174.4(0.987)^{22}\approx130.77y=174.4(0.987)^{25}\approx125.74y=174.4(0.987)^{29}\approx119.33y=174.4(0.987)^{32}\approx114.73y=174.4(0.987)^{35}\approx110.32

Now you have these points:

(5,163.35),(8,157.07),(11,151.02),(15.143.32)(18,137.800),(22,130.77),(25,125.74),(29,119.33),(32,114.73),(35,110.32)

Therefore, you can plot them on the Coordinate Plane:

By definition, when the residual plot shows a pattern, a non-linear regression model is appropriate for the data. Therefore, the Exponential Regression Model is a good fit.

Hence, the answer is:

- Residual Plot:

- First option.
