The first one is, because when you have an exponent multiplied by an exponent, you keep the base and just multiply the exponents when you do this, you get 7^-6. When you have a negative exponent you simply put the exponential answer as if it were positive on the denominator of a fraction with the numerator of 1.

A​ state's recidivism rate is ​22%. This means about ​22% of released prisoners end up back in prison​ (within three​ years). Su
storchak [24]

The probability that both of them go back to prison is 4.48%.

<h3>What is probability?</h3>
  • Probability is a measure of the likelihood of an event occurring.
  • Many events cannot be predicted with total certainty.
  • We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
  • The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

The state recidivism rate is given by 22%.

So, the probability that both of the prisoners will go back to prison will be:

  • = 22% × 22%
  • = 0.22 × 0.22
  • = 4.84%

Hence, the probability that both of them go back to prison is 4.48%.

The temperature at 5 p.m. is 20°F. The temperature at 10 p.m. is -5°f. How many degrees did the temperature fall?
NARA [144]

Hello!

You don't have to worry about the time when the temperature drops.

I believe your answer is 25°F.

If it is 20°F outside, then it takes 20°F to drop the zero. Now, since we are at zero now, and we are trying to get to -5°F. Then all we have to do is add 5 plus 20 and that is 25°F.

I hope it helps!
