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:

11%

Step-by-step explanation:

1500 is the total amount of people

P(group has type B blood)=\frac{165}{1500}11%

Find the solutions to the equation below check all that apply
Vadim26 [7]

A. x=3/2

D. x=1/2


Solve for x over the real numbers:

4 x^2 - 8 x + 3 = 0

The left hand side factors into a product with two terms:

(2 x - 3) (2 x - 1) = 0

Split into two equations:

2 x - 3 = 0 or 2 x - 1 = 0

Add 3 to both sides:

2 x = 3 or 2 x - 1 = 0

Divide both sides by 2:

x = 3/2 or 2 x - 1 = 0

Add 1 to both sides:

x = 3/2 or 2 x = 1

Divide both sides by 2:

Answer:  x = 3/2 or x = 1/2
