Me will give explain the steps so i could understand how you got the answer the values of a, b, and c in scientific notation are 3.47 × 10^-6, 4.61 × 10^7, and 5.52 × 10^7, respectively. complete the following sentences. round so the first factor goes to the hundredths place. a)1.60 b)16.0 × 10^1 c) 1.60 × 10^2 d)1.59 × 10^13 e)0.75 × 10^13 f)7.53 × 10^-13 g)7.53 × 10-^14 h)1.59 × 10^1

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
