Answer:
25.12
Step-by-step explanation:
When calculating probability you need to remember that probability is:
something that you are observing divided by total number of participants.
The number you get is relative value(has value between 0 and 1) and if you want to get it in percentage (more clearly) just multiply it with 100.
In this case we are observing blood type B persons. Number of them is 165.
Total number of persons is 1500. Therefore our calculation looks like this:
165/1500 = 0.11 or the probability is 0.11*100=11%

Answer:
Factors are: 3x+8 & 4x-1
Step-by-step explanation:
12x² + 29x - 8
12x² + 32x - 3x - 8
4x(3x + 8) -1(3x + 8)
(3x + 8)(4x-1)
