Answer:
Step-by-step explanation:
This is a quadratic equation. We'll find the discriminant, but must first rewrite this equation in standard form:
5w2 – 2w + 4 = -4 + 4, or 5w^2 - 2w + 4 = 0
The coefficients of the w terms are {5, -2, 4}
and so the discriminant b^2 - 4ac is 4 - 4(5)(20) = -396
Because the discriminant is negative, we know that there will be two unequal, complex solutions.
Answer:
148°
Step-by-step explanation:
The measure of the intercepted arc QN is twice the measure of inscribed angle QNT.
arc QN = 2(74°) = 148°

<em>Comment on the question and answer</em>
Your description "on the circle between points Q and N" is ambiguous. You used the same description for both points P and R. The interpretation we used is shown in the attachment. If point P is on the long arc NQ, then the measure of arc QPN will be the difference between 148° and 360°, hence 212°. You need to choose the answer that matches the diagram you have.

We call angle QNT an "inscribed angle" because it is a degenerate case of an inscribed angle. The usual case has the vertex of the angle separate from the ends of the arc it intercepts. In the case of a tangent meeting a chord, the vertex is coincident with one of the ends of the intercepted arc. The relation between angle measure and arc measure remains the same: 1 : 2.

Answer:
P(1) = 1 - 8/27 = 19/27
The probability that at least one of them will be elected is 19/27
Step-by-step explanation:
the probability that at least one of them will be elected = 1 - probability that none of them will be elected.
P(1) = 1 - P(None) .....1
Let P(A), P(B) and P(C) represent the probability for each of the three candidates to be elected .
P(A) = P(B) = P(C) = 1/3
The probability for each of the three candidates not to be elected is
P(A)' = P(B)' = P(C)' = 1 - 1/3 = 2/3
P(None) = P(A)' × P(B)' × P(C)'= 2/3 × 2/3 × 2/3 = 8/27
From equation 1. Substituting the value of P(None)
P(1) = 1 - 8/27 = 19/27
The probability that at least one of them will be elected is 19/27
