The drama club is selling short-sleeved shirts for $5 each, and long-sleeved shirts for $10 each. They hope to sell all of the shirts they ordered, to earn a total of $1,750. After the first week of the fundraiser, they sold StartFraction one-third EndFraction of the short-sleeved shirts and StartFraction one-half EndFraction of the long-sleeved shirts, for a total of 100 shirts.This system of equations models the situation. 5x + 10y = 1,750x + A system of equations. 5 x plus 10 y equals 1,750. StartFraction one-third EndFraction x plus StartFraction one-half EndFraction y equals 100.y = 100Let x represent the number of short-sleeved shirts ordered and let y represent the number of long-sleeved shirts ordered.How many short-sleeved shirts were ordered?How many long-sleeved shirts were ordered?

Listed below are annual data for various years. The data are weights (metric tons) of imported lemons and car crash fatality rates per 100,000 population. Construct a scatterplot, find the value of the linear correlation coefficient r, and find theP-value using α=0.05. Is there sufficient evidence to conclude that there is a linear correlation between lemon imports and crash fatality rates? Do the results suggest that imported lemons cause car fatalities?Lemon_Imports_(x) Crash_Fatality_Rate_(y)230 15.8264 15.6359 15.5482 15.3531 14.9What are the null and alternative hypotheses?

Atmospheric pressure, measured in pounds per square inch (psi) is the force exerted by Earth's atmosphere over a given area. The atmospheric pressure, p, exerted on an airplane flying at an altitude of a miles above sea level can be approximated by the model shown below. What is the best interpretation of 0.8^a in this equation?p = 14.63 - 0.8^aA. If the airplane reaches the outer extent of the Earth's atmosphere, the atmospheric pressure will be 0.8 psi.B. If the airplane is at sea level, the atmospheric pressure will be 0.8 psi.C. For each mile that the altitude increases, the atmospheric pressure decreases 20%.D. For each mile that the altitude increases, the atmospheric pressure increases 20%.
