4 floors with 6 class rooms each = 6*4 = 24 total class rooms.
24 class rooms x 34 students in each one = 816 total students.
It would be 6:24 but simplify it to 1:4. I do not understand about what you mean by fraction and decimal. Maybe you could rephrase your question?
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)

Answer:
-327
Step-by-step explanation:
3(4 + 7) - 5 • 72=??
distributive property
3(4)+3(7)-5 times 72
12+21-5 times 72
33-5 times 72
33-360
