Answer:
The correct option is 1.
Step-by-step explanation:
it is given that the probability of a randomly selected point on the grid below is in the blue area is 9/16.
In the given grid we have only two colors that are blue and white.
Let A be the event of a randomly selected point on the given grid is in the blue area.

If the randomly selected point on the given grid does not lie in the blue area, it means it lies on white area.
We will calculate P(A'), to find the probability that a randomly selected point is in the white on the grid.
We know that the sum of the probability is 1.


It is given that 

Therefore option 1 is correct.
Answer:
Adding 3
Step-by-step explanation:
-3 + 3 = 0
0 + 3 = 3
3 +3 = 6
6 + 3 = 9
I'm pretty sure that mean and average both mean(pun not intended) the total value of the data divided by the number of values, giving you an average.
Mode is the value that is repeated most often. For example, if your data set is 1, 3, 4, 2, 2 the mode is 2 because it is repeated twice. If there was another 3, 4, or 1 then the mode would be both values, as they both were repeated the most often.
Hope this helped :)
1600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.
1) 180°. All the interior angles in a triangle ALWAYS add to 180°.
2) x = 60°. As stated in 1), all angles in a traingle add to 180° so knowing this, x = 180 - 70 - 50 = 60°.
3) <A = 90, <B = 60, <C = 30. Knowing that all angles in a traingle add to 180, we can make an equation. 6x + 4x + 2x = 180 or 12x = 180. This means x is 15°. Now we just need to multiply it. 6x = 90, 4x = 60 and 2x = 30.
