While on Casey's computer, you notice that a model for a recent experiment is completed. The modelgives the temperature (T) as a function of time (t) as given below. As before, a time of t = Orepresentsthe time of data collection, with negative values representing earlier times. Knowing Casey, they willwant to know the domain, range, and other information about the model. You review the model andprovide the information that Casey will request.T (t)The vertical asymptote is t ==Enter the domain in interval notation. To enter ∞, type infinity.As t approaches the vertical asymptote,As t approaches ∞,In (2t + 12) + 1.3T (t) →T (t) →

Use the data in the table below for Questions A - G. Remember to show ALL your work. A researcher performs a study investigating differences in perceived stress during the COVID-19 pandemic in undergraduate students. She measures levels of depression in a group of 7 first year undergraduates as well as in a group of 7 fourth year undergraduates using a continuous variable scale. The data are presented in the following table: First Year Fourth Year (X) (Y) 4 6. 10 10 9. 8 10 4 2 A. Calculate the mean for the first year group and the mode for the fourth year group В. In general, what is the purpose of obtaining a measure of central tendency? Calculate the range for the first year group. Describe one advantage and one disadvantage of the range as a measure of variability. С. D. Calculate the variance for each of the two separate groups Е.

In 1991 it was estimated that there were about 100 breeding pairs of Northern Spotted Owls. It was determined that their population had been declining at a rate of 7% each year. If 'P' is the population of the owls, write the equation that would model the population of the Northern Spotted Owl after t years. O A.P = 100 (93)* O B. P = 100 (7%)' OC.P= 100 (1.7)* OD. P = 100 (7)
The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. 11.8 8.6 6.8 3.7 2.8 2.6 2.6 0.9 14.1 11.5 9.8 6.9 6.6 6.5 6.2 4.6 thousands of automatic weapons y = murders per 100,000 residents %3D This data can be modeled by the equation y = 0.86x + 3.99. Use this equation to answer the following; A) How many murders per 100,000 residents can be expected in a state with 7.7 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 1.9 thousand automatic weapons? Answer = Round to 3 decimal places.
Below is the data for speed vs fuel consumption. The first set is speed(x); the second is fuel (y). if x = 10, y = 21 if x = 20 y =13, if x=30 y=10 if x = 40 y =8 if x = 50 y=7 if x =60 y = 5.9 if x = 70 y = 6.3 if x = 80 y = 6.95 if x = 90 y = 7.57 if x = 100 y = 8.27 if x = 110 y = 9.03 if x = 120 y = 9.87 if x = 130 y = 10.79 if x = 140 y = 11.77 and if x = 150 y =12.83. The equation of the LSR line is y^ = 11.058 - .015x The average of (x, y) are (80, 9.9) respectively. Find another point using the LSR equation, and graph the line
A red maple sapling was 3 feet tall when planted in 2010. Six years later, the tree was 18 feet tall. The growth rate of the tree is constant over time.

Engineers concerned about a tower's stability have done extensive studies of its increasing tilt. Measurements of the lean of the tower over time provide much useful information. The following table gives measurements for the years 1975 to 1987. The variable "lean" represents the difference between where a point on the tower would be if the tower were straight and where it actually is. The data are coded as tenths of a millimeter in excess of 2.9 meters, so that the 1975 lean, which was 2.9647 meters, appears in the table as 647. Only the last two digits of the year were entered into the computer. 80 83 86 75 76 77 78 647 649 660 672 79 81 82 84 85 678 693 701 703 717 722 729 747 (a) Plot the data.

Please help me better understand this problem. Researchers want to determine if heavier cars use more gasoline? To answer this question, a researcher randomly selected 15 cars. He collected their weight (in hundreds of pounds) and the mileage (MPG) for each car. From a scatterplot made with the data, a linear model seemed appropriate and the following output was obtained in photo below. Question: Determine the proportion of the variation in mileage is accounted for by the linear relationship with the weight of the car and also determine the estimate of the regression standard deviation.
