Jonah collects rainwater in a large barrel that weighs 30 pounds. when there are 10 gallons of water in the barrel, the total weight of the barrel and the water is 113.4 pounds. when there are 20 gallons of water, the total weight is 196.8 pounds. which equation and graph match this situation? a. y = 8.34x + 30 b. y = 30x + 8.34 c. y = 30x + 8.34 d. y = 8.34x + 30

Asystem of equation is shown below 6x - 2y equals 3 . and 5x + 3y equals 4. would you solve by substitution or elimination? and why

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms
