Greatest common multiple is 2
If 1 and 2 becomes multiplayed gave 3 and 3+3=4 (4-2)+(4-1)= 2+3=4 and 4 is n.
With
a standard deviation of 6 minutes, we will test the hypothesis that σ = 6
against the alternative that σ < 6 if a random sample of the test
times of 20 high school seniors has a standard deviation s = 4.51. use a
0.05 level of significance.

Answer:

Step-by-step explanation:
<u>Solution 1:</u>
As the angles are marked, the figure forms a 30-60-90 right triangle with the height. Therefore the height will be
. The area of this figure can be given as
, therefore our answer is
.
<u>Solution 2:</u>
The figure forms two triangles when cut by the shortest diagonal. The area of a triangle can be given by
. Since there are 2 of these triangles, the area of the entire figure is
.
