Qno.5: solve by adding or subtracting.
2x+2y=-4
2x+4y=-12
q no.6: solve the linear system model by multiplying first .
the drama club had a car wash as a fundraiser where they washed a total of 41 vehicles. members washed x cars at $5 each and y trucks at $8 each and made a total of $250.the system of equations (1) x+y=41 (2)5x+8y=250 can be used to represent this situation. find the number of each of vehicle they washed.
q no.8: graph the system of linear inequalities. give two ordered pairs that are solutions and two that are not solutions.
y(> and the line under it)3x+3
y< -2

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t.inv.2t to find the value of t for the interval calculation.
