So b=-2 so you plug b in

l(-2)l + (-2)^3.

The absolute value of -2 is just 2 so now it is

2 + (-2)^3.

-2 * -2 is 4 but 4 * -2 is -8. So 2 + (-8) or 2 - 8 which comes to equal (-6) or negative six.

An electronic product contains 53 integrated circuits. The probability that any integrated circuit is defective is 0.02, and the
Varvara68 [4.7K]

Answer: Hello!

Here you have 53 integrated circuits, each with a probability of 0.02 of being defective.

If only one of them is defective, then the electronic product doesnt work.

Then we need the calculate the probability in wich all the 53 circuits arent defective.

the probability for each one to not be defective is 1 - 0.02 = 0.98

And if i want to see the probability for all of them to work fine, then i need to do the product of all the probabilities, this is multiply 0.98 53 times, or:

0.98^{53} = 0.34275

rounding to the four decimal place, we have: 0.3428

Wich is a kinda small probability for our product to work.

The jet stream is traveling nearly due south from Wyoming to Colorado at 110 knots. If the plane’s speed is 400 knots, what will
son4ous [18]

Considering the direction of the wind, it is found that the ground speed needs to be of 510 knots.

<h3>What is the ground speed?</h3>

The ground speed, considering that the wind is flowing from Wyoming to Colorado, and the same direction as the trip, is given by:

G = Plane speed + Wind speed.

In this problem, we have that the speeds are given as follows:

  • Plane: 400 knots.
  • Wind: 110 knots.

Hence the ground speed is given by:

G = 400 + 110 = 510 knots.

A similar problem, involving plane and wind's speed, is given at brainly.com/question/25547425

Elza [17]
The answer would be 20-(3+2) because first you do what is inside the parentheses 3+2=5 and now you have to subtract 20-5=15. Cody’s change should be $15.
