So sin in math means:
In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.
Con in math means:
In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.
in this case it has to be a sin. So its either A, or B.
ii think a tho
3(-2) -9
-6-9
-15
-15 Is the value that represents the last expression
The number shown here is written in scientific notation since it’s composed of a decimal that is between 1 and 10 in this case 2.98 and a power of 10 in this case 10 to the 7th power. Therefore, this number is written in proper scientific notation.
1- Probability 1/2
2-Probability 5/6
3-Probability 5/6
4-Probability 3/4
maybe you mistyped 2 but those are the probabilities for each with what the question says
