The probability is 0.2005.
We compute the z-score for this time:
z = (X-μ)/σ = (230-184)/55 = 0.84
Looking this up in a z-table (http://www.z-table.com) we see that the area to the left of this (less than this) is 0.7995. We want the area greater than this, so we subtract this from 1:
1 - 0.7995 = 0.2005.
Density and temperature and number of moles of gas
Step-by-step explanation:
X + Y + 6X - 4Y - 2 would be 7x - 3y -2
:) hope this helped let me know if you need more help! :)
Answer: n = 1, n = -1/3
<u>Step-by-step explanation:</u>
(3n - 1)² = 12n + 8
9n² - 6n + 1 = 12n + 8
9n² - 18n - 7 = 0
Substitute -18n with 3n - 21n and find the common factor of each side:
9n² + 3n -21n - 7 = 0
3n(<u>3n + 1</u>) -3(<u>3n + 1</u>) = 0
(3n - 3) (3n + 1) = 0
Solve for each factor:
3n - 3 = 0 3n + 1 = 0
3n = 3 3n = -1
n = 1 n = -1/3
