The distribution of bladder volume in men is approximately normal with mean 550 ml and standard deviation 100 ml. what percent of men have a bladder volume larger than 450 ml? round to the nearest whole number.

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.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

hi there!

the answer will be d: 2
