Answer:
Equivelant fractions.
Step-by-step explanation:
Ask your self..
How did the 1/3 become 7/21?
Its very simple multiply 1/3's numerator and denominator by 7
So its going to be.. 1 x 7 = 7
3 x 7 = 21

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

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%.

Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
Answer:
Step-by-step explanation:
So, we are given:
First, we should immediately rule out 0 as an answer. This is because the if , the equation would be undefined.
Now, cross multiply.
Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).
We didn't run into any possibilities for extraneous solutions.
Answer:
x+5
Step-by-step explanation:
When you move to the right or left , that's on the x axis. And since it's to the right, the x- coordinate becomes larger. Hope this helps!
