Step-by-step explanation:
√3-1
after subtracting one from √3 and dividing two you get √3-1
Hey there!
If we have two white marbles and seven purple marbles, our first probability is out of nine.
First of all, we have the probability of selecting a purple marble, 7/9.
Now, if we do not replace it, there are only eight marbles left. Therefore, getting a white marble is 2/8, or 1/4.
We multiply these probabilities together to get our answer to a.
7/9(1/4)= 7/36
a. 7/36
Now, let's do b. We have 2/9, and then 1/8, giving us 1/36.
b. 1/36
Now, let's calculate selecting two purple to help us with C.
We have 7/9, and then 6/8, or 3/4.
7/9(3/4)= 7/12
Since there is a majority of purple marbles, there is a C) greater probability of selecting two purple marbles in a row.
I hope this helps!
Answer:
The measure of all the three angles of the triangle are;
56°, 72° and 52°
Step-by-step explanation:
The given parameters are;
The measure of the exterior angle of the triangle = 124°
The measure of one of the opposite interior angle = 72°
Therefore, we have;
The measure of the interior angle adjacent to the exterior triangle = 180° - 124° = 56° (Sum of angles on a straight line)
From the sum of the interior angles in a triangle = 180°, we have;
The measure of the third interior angle of the triangle = 180° - 56° - 72° = 52°
Therefore, the measure of all the three angles of the triangle are;
56°, 72° and 52°.
Answer:
D. Supplementary. By definition a supplementary angle is a straight angle measuring 180 degrees
