Given that 8% of the students are Swedish, this means that 100 - 8 = 92% are not Swedish.
Let S represent the event that a student is Swedish and N represent the event that a student is not a Swedish.
Then, the probability that a student chosen at random is a Swedish, P(S), = 8% = 0.08
The probability that a student chosen at random is not a Swedish, P(N), = 92% = 0.92
That the first Swedish person found was on the third trial means that the first and second trial produced a non-Swedish.
Therefore, the required probability = 0.92 x 0.92 x 0.08 = 0.068 to three decimal places.
Answer:
C) 5.6
Step-by-step explanation:
In an AC circuit, the current changes periodically direction, following a sine-like function.
As a result, we have the following:
- The current through the resistive branch of the circuit is always in phase with the voltage
- However, the voltage in the inductive branch of the circuit preceeds the current by a phase difference of 90 degrees
The inductance of the circuit therefore is basically the resultant vector of the resistance (R) and the inductance (L), and the phase angle is related to the two quantities by the relationship:
In this problem, we have:
is the phase angle
is the resistance of the circuit
Therefore, the inductance is:
Answer:
answer is the ratios are not equivalent or not in proportion
Step-by-step explanation:
you can find it by crops multiplication
4/7
8/11
4*11
8*7
44=56
Therefore it is not in proportion
Answer: (x, y) = (2, 3)
This is the system of equations 2x - 3y = -5, 5x - 2y = 4. Multiply the first equation by 2 and the second equation by 3 to get 4x - 6y = -10, 15x - 6y = 12. Now we can use elimination: subtract the equations to get -11x = -22, so x = 2. 2x - 3y = 2(2) - 3y = 4 - 3y = -5, so 3y = 9 and y = 3. The solution is (2, 3).
i hope this helped! :D
