An electronics company is looking to develop a regression model to predict the number of units sold for a special running watch. Data is provided below:

Sales (units) Price ($) Advertising ($) Holiday
500 100 50 Yes
480 120 40 Yes
485 110 45 No
510 103 55 Yes
490 108 40 No
488 109 30 No
496 106 45 Yes

Compile a spreadsheet for the data and determine the predicted number of units sold if the watch is sold on a holiday for $200 while $150 is spent on advertising.

a) 424 b) 420 c) 860 d) 370

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
