Answer:
C.) 14
Step-by-step explanation:
Look at the triangle: angles b and c have the same arch, so they are congruent.
In a triangle, if two angles are congruent, then the triangle is isosceles, having two equal sides.
The sides opposite the congruent angles are congruent:
∠B → opposite side → AC
∠C → opposite side → AB
The sides AB and AC are equal. Make an equation:
![AB=AC\\\\2x=3x-7](https://tex.z-dn.net/?f=AB%3DAC%5C%5C%5C%5C2x%3D3x-7)
Simplify the equation, solving for x. Add 7 to both sides:
![2x+7=3x-7+7\\\\2x+7=3x](https://tex.z-dn.net/?f=2x%2B7%3D3x-7%2B7%5C%5C%5C%5C2x%2B7%3D3x)
Subtract 2x from both sides:
![2x-2x+7=3x-2x\\\\7=x](https://tex.z-dn.net/?f=2x-2x%2B7%3D3x-2x%5C%5C%5C%5C7%3Dx)
The value of x is 7. Insert the value of x into the given length of AC:
![AC=3(7)-7](https://tex.z-dn.net/?f=AC%3D3%287%29-7)
Simplify multiplication:
![AC=21-7](https://tex.z-dn.net/?f=AC%3D21-7)
Subtract:
![AC=14](https://tex.z-dn.net/?f=AC%3D14)
Therefore, the length of the line segment AC is 14.

Answer:
0.1319 or 13.2%
Step-by-step explanation:
You can solve this using the binomial probability formula.
The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.
Then, we can set the equation as follows:
P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k)
n=4, x=2, k=2
when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157
when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154
when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008
Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)

Step-by-step explanation:
kindly check the attached image below to Determine whether the given set S is a subspace of the vector space <u><em>(which is contained within a different vector space. So all the subspace is a kind of vector space in their own way, although it is also defined relative to some of the other larger vector space. The linear subspace is more often than not simply called a subspace whenever the situation serves to differentiate it from other types of subspaces.)</em></u> V.A
The number that equals 280 tenths + 19 thousandths is 28.019
<h3>How to determine the number?</h3>
The statement is given as:
280 tenths + 19 thousandths
Rewrite the terms of the expression as fractions
So, we have
280/10 + 19/1000
Evaluate the quotients
28.0 + 0.019
Add both numbers
28.019
Hence, the number that equals 280 tenths + 19 thousandths is 28.019
