Dr. sperry, a biologist, is using excel to track growth rates of different populations of bacteria. she has a very complex formula in one cell. it begins with “round”. dr. sperry would like to see exactly how excel’s calculation reached the final rounded value that she sees in the cell. what could dr. sperry do to best understand how the calculation was made? try different formulas on her own until she reaches the value shown in excel click on the evaluate formula button in the formulas tab and then click “step in” select the cell and then look at the formula in the formula field of the ribbon remove “round” from the formula in order to see the actual value before rounding

The year is 2278, and the starship enterprise is running low on dilithium crystals, which are used to regulate the matter-antimatter reactions that propel the ship across the universe. without the crystals, space-time travel is not possible. if there is only one known source of dilithium crystals, the necessary conditions for a monopoly are met. part 2 (1 point)see hint if the crystals are government owned or government regulated, and the government wants to create the greatest welfare for society, then it should set the price choose one or more: a. so only the rich can afford space-time travel. b. at the profit-maximizing price. c. at the efficient price. d. using the marginal-cost pricing rule. e. so everyone can afford space-time travel. f. at the monopoly price.

Mauro products distributes a single product, a woven basket whose selling price is $15 and whose variable expense is $12 per unit. the company’s monthly fixed expense is $4,200. required: 1. solve for the company’s break-even point in unit sales using the equation method. 2. solve for the company’s break-even point in dollar sales using the equation method and the cm ratio. (do not round intermediate calculations. round "cm ratio percent" to nearest whole percent.) 3. solve for the company’s break-even point in unit sales using the formula method. 4. solve for the company’s break-even point in dollar sales using the formula method and the cm ratio. (do not round intermediate calculations. round "cm ratio percent" to nearest whole percent.)
