Doque Power Company wants to develop a regression model to help predict its daily peak power demand. This prediction is useful in determining how much generating capacity needs to be available (or purchased from competitors) on a daily basis. The daily peak power demand is influenced primarily by the weather and the day of the week. a. Build a simple linear regression model to predict peak power demand using maximum daily temperature. What is the estimated regression equation?
b. Prepare a line chart plotting the actual peak demand data against the values predicted by this regression equation. How well does the model fit the data?
c. Interpret the R2 statistic for this model.
d. Build a multiple linear regression model to predict peak power demand using maximum daily temperature and the day of the week as independent variables. (Note: This model will have seven independent variables.) What is the estimated regression equation?
e. Prepare a line chart plotting the actual peak demand data against the values predicted by this regression equation. How well does the model fit the data?
f. Interpret the R2 statistic for this model.
g. Using the model you developed in part d, what is the estimated peak power demand Duque should expect on a Wednesday in July when the daily high temperature is forecasted to be 94 degrees?
h. Compute a 95% prediction interval for the estimate in the previous question. Explain the managerial implications of this interval for Duque.

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.

On this question. a hypothermia occurs when a person's body temperature drops below 95 degrees fahrenheit. write and solve an inequality that describes how much lower the body temperature of a person with hypothermia will be than the body temperature of a person with a normal temperature of 98.6 degrees fahrenheit
