To solve this, we use the z-test.
z = (x – u) / σ
when x = 450
z = (450 – 550) / 100
z = -1
We use the standard distribution tables to find for P.
P = 0.1587
Since we are looking for values greater than x = 450,
therefore:
1 – 0.1587 = 0.8413
This means that 84.13% have bladder volume larger than 450
mL.
we have

<u>Find the greatest common factor GCF</u>
we know that

so
The GCF is equal to 
therefore

<u>the answer is</u>
The number is 
Answer:
probability the spy is able to unlock the tablet on his first try.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
1 correct password, so 
Total outcomes:
Nine-digit codes.
For each digit, there are 10 possible outcomes. So

What is the probability the spy is able to unlock the tablet on his first try?

probability the spy is able to unlock the tablet on his first try.
"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409.
The greatest possible value of that fraction is. (239)/(409 squared) .
