Solution

failed
failed
Paso 1: Evaluar la función

Sustituimos \( x = 1 \) y \( y = 2 \) en la función \( f(x, y) = 4x - y^{2} + 3 \).

Paso 2: Sustitución de valores

Realizamos la sustitución: \[ f(1, 2) = 4(1) - (2)^{2} + 3 \]

Paso 3: Calcular el resultado

Calculamos cada término: \[ f(1, 2) = 4 - 4 + 3 = 3 \]

Respuesta Final

\(\boxed{3}\)

Of the people who fished at Clearwater Park today, 30 had a fishing license, and 20 did not. Of the people who fished at Mountain View Park today, 32 had a license, and 8 did not. (No one fished at both parks.) Suppose that one fisher from each park is chosen at random. What is the probability that the fisher chosen from Clearwater had a license and the fisher chosen from Mountain View did not have a license?

Disk drives have been getting larger. Their capacity is now often given in terabytes (TB) where 1 TB=1000 gigabytes, or about a trillion bytes. A survey of prices for external disk drives found the data shown to the right. For this data, we want to predict Price from Capacity. Complete parts a through i below. Click the icon to view the disk drive data and summary statistics. b1=142.35 (Round to two decimal places as needed.) b) What does the slope mean, in this context? A. It indicates the additional price in dollars for each additional TB of capacity. B. It is meaningless and should not be interpreted. C. It indicates the price for a hard drive with no capacity. This could be interpreted as the cost of the parts common to all drives. D. It indicates the additional capacity in TB for each additional dollar of price. E. It indicates the additional capacity in gigabytes for each additional dollar of price. c) Find the intercept, b0. b0= (Round to two decimal places as needed.)
