In this question there is a small trick that needs to be understood. Basically the ratio in the question is given as a decimal. It can be expressed as a ratio as well.
Ratio of students that voted for winner to the total number of voters = 95:100
The total number of students that voted = 60
Let us assume the common ratio to be = x
then
100x = 60
x = 60/100
   = 0.6
Then
The number of votes that the winner got = 95 * 0.6
                                                                 = 57
So 57 students voted for the winning candidate.

A researcher in a Human Resources Unit presented a recent study, which showed a statistical significance between length of staff
alexgriva [62]

Answer:

To explain to her manager that her research does not mean the length of staff lunch breaks should be reduced, the best thing to say from the options is:

A significant result does not mean that the effect is important.

Step-by-step explanation:

1. Saying "A significant result means that the effect is strong.", she is contradicting the message she is trying to pass across, as this would only trigger her manager to reduce the length of lunch break. The manager would take very seriously anything that has a strong effect on their productivity.

2. Saying "A significant result means that the effect is not relevant" wouldn't pass her intended message across. The effect might not be relevant to productivity, but will be relevant to another department, so something would be done about their lunch time break.

3. Saying "A significant result does not mean that the effect is important", she would pass her message very clearly. The manager would hear of a negligible effect, and would not worry about any effect of their lunch break time.

4. Saying "A significant result means that the effect is weak", she sounds direct, admitting that there is an effect, but a weak one. That is not good enough.

Solve for x in the equation X2-8x+41 = 0 -
djverab [1.8K]

Answer:

The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D  

Step-by-step explanation:

Given equation as :

x² - 8 x + 41 = 0

For quadratic equation  ax² + b x + c = 0

The value of x = \frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}

∴ For equation x² - 8 x + 41 = 0

Or,                x = \frac{8\pm \sqrt{-8^{2}-4\times 1\times 41}}{2\times 1}

Or,                x = \frac{8\pm \sqrt{-100}}{2}

Or,                x = \frac{8\pm 10i}{2}

∴                  x = ( 4 + 2 i ) , ( 4 - 2 i )

Hence The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D     Answer
