The probability of selecting a blue marble is <u>3/14</u>. Hence, <u>option D</u> is the right choice.
The probability of any event is the chance of the occurrence of that event. It is given as the ratio of the number of favorable outcomes to the event to the total number of outcomes possible in the experiment.
If we consider an event A, the number of favorable outcomes to event A be n, and the total number of outcomes be S, then the probability of event A is given as:
P(A) = n/S.
Let us take the event of selecting a blue marble from the experiment of selecting a marble randomly from the bag be A.
The number of outcomes favorable to event A (n) = 3 {3 blue marbles}.
The total number of outcomes (S) = 14 {Total number of marbles in the bag = 4 red + 3 blue + 7 green = 14 marbles}.
Therefore, the probability of selecting a blue marble is,
P(A) = n/S = 3/14.
Hence, <u>option D</u> is the right choice.

Answer:
The slope of the line is m = 1
Step-by-step explanation:
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m = y2-y1 / x2-x1
m = 2 - 5 / -1 - 2
m = -3 / -3
m = 1
X1 is 2
Y1 is 5
X2 is -1
Y2 is 2
Answer:
x = 1
Step-by-step explanation:
you can first find the two zeroes
that would be
x + 2 = 0
x - 4 = 0
x = {-2, 4}
then you average them
-2 + 4 = 2
2 / 2 = 1
the aos is 1
Answer:
your questions is wrong it's 2×2-6x=56
answer= X=-9
Step-by-step explanation:
2×2-6x=56
4-6x=56
-6x=56-4
-6x=54
-X=54/6
-X=9
X=-9
The answer is 12 including both sides and angles.
When you cut a square piece of paper from one point to the opposite point it should make two triangles.
Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides
So 12, sides and angles added together.
