Answer:
97.3%
Step-by-step explanation:
Let the three bulbs be A, B and C respectively.
Let P(A) denote the probability that the first bulb will burn out
Let P(B) denote the probability that the second bulb will burn out
Let P(C) denote the probability that the third bulb will burn out
Now, we are told that Each one has a 30% probability of burning out within the month.
Thus;
P(A) = P(B) = P(C) = 30% = 0.3
Now, probability that at the end of the month at least one of the bulbs will be lit will be given as;
P(at least one bulb will be lit) = 1 - (P(A) × P(B) × P(C))
P(at least one bulb will be lit) = 1 - (0.3 × 0.3 × 0.3) = 0.973 = 97.3%
Answer:
$8,961 is your answer.
Step-by-step explanation:
What you do is multiply.
<em>15,450 x 14% = 2,163</em>
<em>2,163 x 3 = $6,489</em>
<em>$15,450 - $6,489 = $8,961</em>
$8,961 is your answer.
Applying the definition of the diagonals of a parallelogram, the value of x is: <em>D. 4.</em>
<h3>The Diagonals of a Parallelogram</h3>
- A parallelogram is a quadrilateral that has two opposite sides that are parallel and congruent to each other.
- The diagonals of a parallelogram are equal and also bisect each other into equal segments.
Thus:
12 = 3x (congruent segments)
Divide both sides by 3
4 = x
x = 4
Therefore, applying the definition of the diagonals of a parallelogram, the value of x is: <em>D. 4.</em>
