There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60
Answer: Option B 3!((6×5×4)-1)
Step-by-step explanation:
6! - 3!
= (1×2×3×4×5×6) - (1×2×3)
= 720 - 6
= 714
As you told you forgot to put options lemme answer it.
It will be option B
3!((6×5×4)-1)
It will be 6((6×5×4)-1)
= 6(120) -6
= 720 - 6
= 714

<h3>Answer: 0.47178 Step-by-step explanation:
Find the probability for each p(X=x) up to 5 using the equation: (x-1)C(r-1)*p^r * q^x-r,
where x is number of days, p = .3 (prob of rain). q=.7 (prob of not rain), and r=2 (second day of rain). also C means choose.
So p(X=1) = 0
p(X=2) = 1C1 * .3^2 * .7^0 = .09
P(X=3) = 2C1 * .3^2 * .7^1 = .126
P(X=4) = 3C1 * .3^2 * .7^2 = .1323
P(X=5) = 4C1 * .3^2 * .7^3 = .12348
Then add all of them up
0+.09+.126+.1323+.12348 = .47178</h3>
Answer:
70%
Step-by-step explanation:
First find the number that were rejected
10-3 = 7
Then take that over the total
7/10
