During a science experiment the temperature of a solution in beaker 1 was 5 degrees below zero. the temperature of a solution in beaker 2 was the opposite of the temperature in beaker 1. what was the temperature in beaker 2?

5 degrees

Step-by-step explanation:

We are given that during a science experiment

The temperature of a solution in a beaker 1 5 degrees below zero

The temperature of solution in a beaker 2 was opposite of the temperature in beaker 1

We have to determine the temperature of beaker 2.

It mean temperature of beaker 1 solution=-5 degrees

According to question

Temperature of beaker 2 solution =5 degrees

Hence, the temperature of solution in a beaker 2 =5 degrees

The probability that David will eat a healthy breakfast or that it will rain is 0.85 or 85%.

Step-by-step explanation:

Consider the provided information.

There is an 80% chance David will eat a healthy breakfast.

P(H) = 0.8

There is a 25% chance that it will rain.

P(R) = 0.25

The probability of David will eat a healthy breakfast and it will rain is:

P(H ∩ R)  = 0.8 × 0.25 = 0.2

P(H ∪ R) = P(H) + P(R) - P(H ∩ R)

P(H ∪ R) = 0.8 + 0.25 - 0.2

P(H ∪ R) = 0.85

Hence, the probability that David will eat a healthy breakfast or that it will rain is 0.85 or 85%.
