The polluted water from Pond 1 drains into Pond 2 at 8 gallons per minute. Pond 1 initially contains 200 gallons of water and 40 lb of pollutant, whereas Pond 2 initially contains 400 gallons of water and 80 lb of pollutant. Clean water enters Pond 1 at 8 gallons per minute, whereas the water from Pond 2 drains to the ground at 1 gallons per minute. Write an initial value problem that models the rates of change of pollutants in Lake A and in Lake B with time. Do not solve.
Q2 (a) Azli and Iman are both traveling for Batu Pahat to Melaka on daily basis. The average travelling time for both them is 98.4 minutes with a standard deviation of 7.8 minutes and 110.7 minutes with standard derivation of 29.8 minutes respectively. Assume that the traveling population are approximately normal distributed and random samples of traveling time of Azli and Iman are 36 and 49 respectively. (i) Calculate the probability of Azli's average travelling time to be more than 100 minutes. (ii) Find the probability of Iman's average travelling time to be in between 105 and 115 minutes.

Over the years a farmer has collected data on the average volume of the oranges in his crop in cubic inches based on the number of sunny days and 120 day growing session. The equation of the line of best fit is volume equals 3+0.08 number of sunny days. Find and interpret the residual for an average orange volume of 8 cubic inches in a season with 45 sunny days
Ten years ago, the town of Easton decided to increase its annual spending on education so that its high school graduates would be able to earn higher wages. Now Easton has asked you to evaluate the effectiveness of the spending increase. Their data show that before the spending increase, the average annual salary of recent high school graduates was $25,000 and that now that average salary has risen to $28,500. Fortunately for your analysis, a neighboring community (Allentown) did not change its annual spending on education. Ten years ago, recent Allentown high school graduates earned an average of $22,500, and now that average is $23,750. (a) Use a difference-in-differences estimator to determine whether Easton’s spending increase caused the wages of their high school graduates to increase. please provide an accurate answer.

(1 point) Some shrubs have the useful ability to resprout from their roots after their tops are destroyed. Fire is a particular threat to shrubs in dry climates, as it can injure the roots as well as destroy the aboveground material. One study of resprouting took place in a dry area of Mexico. The investigation clipped the tops of samples of several species of shrubs. In some cases, they also applied a propane torch to the stumps to simulate a fire. Of 14 specimens of a particular species, 5 resprouted after fire. Estimate with 96% confidence the proportion of all shrubs of this species that will resprout after fire. Interval: to
The Organization for Economic Cooperation and Development (OECD) consists of 20 industrialized countries. For these nations, the prediction equation relating y = child poverty rate (in percentage points) to x = social expenditure as a percentage of gross domestic product (GDP) is = 22-1.3x. In 2000, the actual child poverty rate ranged from 2.8% (in Finland) to 21.9% (in the U.S.). Social expenditure as a percentage of GDP ranged from 2% (in the United States) to 16% (in Denmark). What is the value of the y-intercept (a) estimated in the linear prediction equation provided above (= 22-1.3x)? Also, interpret the y-intercept. y-intercept: Interpretation of y-intercept:
its not 35,500.
