Answer:
Step-by-step explanation:
A.
Yes half of twelve is 6 and 6 miles is more than 5.75 miles
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.
Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!
For example just flip 3/7 to 7/3
