Step-by-step explanation:

p(x) =  {x}^{3}  - 4x - 5 \\ p( - 2) =  {( - 2)}^{3}  - 4( - 2) - 5 \\  =  - 8 + 8 - 5 \\  =  - 5

Answer:

The answer would be -5.

Step-by-step explanation:

First I plugged in negative 2 for every x in the equation, which gives me:

p(-2) = (-2)³ - (4(-2)) - 5.

We solve for the exponents first, which gives us a total of -8 because we are multiplying -2 by itself 3 times. Then we multiply 4 and -2, which gives us negstive 8. However, the first -8 and the second -8 cancel out because the equation has a - sign in between the two, leaving us with only -5. -5 is the answer.

Larry reads that 1 out of 4 eggs contains salmonella bacteria, so he never uses more than 3 eggs in cooking. If eggs do or don't
aleksley [76]

Answer:

57.8125% or approx. 57.8%

Step-by-step explanation:

There is a 1/4, or 25%, or 0.25 chance that an egg has salmonella.

Thus, there is a 75%, or 0.75 chance that an egg DOESN'T contain salmonella.

Let's find the probability that all 3 of Larry's eggs are free from salmonella. Larry would have to hit that 75% chance 3 times in a row. The chance of that happening is:

0.75 * 0.75 * 0.75 = 0.75^3 = 0.421875

From this, we can deduce that if there is a 0.421875 (42.1875%) chance that all eggs are safe to eat, there must be a...

1 - 0.421875 = 0.578125

...0.578125 (57.8125%) chance that 1 or more of Larry's eggs do have salmonella.

Answer: approx. 57.8% or 57.8125%
