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:
A. 85
Step-by-step explanation:
<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>
Answer:
35
Step-by-step explanation:
It’s a 90 degree angle. 3x35=105 and 105-15=90
In case you can't find
(1 * 10^-6)*(7.5 * 10^18) = (1*7.5) * 10^(-6+18) = 7.5*10^12
in your head, your calculator can help.
