The profit, in dollars, of selling n items is given by P(n) = 0.86n - 2800. Identify the slope and the y-intercept.

Slope - 0.86

Y-Intercept - (0, -2800)

Step-by-step explanation:

The slope is the rate at which the x value is increasing, in the form of y = mx + b. B would represent the Y-intercept, as that's the value of x when y is equal to 0.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
