The scheduled arrival time for a daily flight from Boston to New York is 9:35 am. Historical data show that the arrival time fol
Lady_Fox [76]

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

M = \frac{a+b}{2}

The standard deviation is:

S = \sqrt{\frac{(b-a)^{2}}{12}}

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5

Standard deviation:

S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

6% of it is 27<br> I need help. Someone please give me a explanation of how to do this.
Ghella [55]

Answer:

You take 6% of a number and the resulting number is 27.

To do this you need to change the percent into a fraction.

6% = 6/100

This is the number you need to multiply to the number you need to find, A.

6/100 A = 27

Solve for x

6 A = 27x100

A= 2700/6

A = 450

Check your answer:

6/100 (A) = 27

6/100 (450) = 27

(6x450) /100 = 27

2700 / 100 = 27

27 = 27

4(5x-3)=48<br><img src="https://tex.z-dn.net/?f=4%285x%20-%203%29%3D%2048" id="TexFormula1" title="4(5x - 3)= 48" alt="4(5x - 3)

Hello, My Dear Friend!

Solution for 4(5x-3)=48 equation:

<span>Simplifying:
</span>4(5x + -3) = 48<span>

</span><span>Reorder the terms:
</span>4(-3 + 5x) = 48
(-3 * 4 + 5x * 4) = 48
(-12 + 20x) = 48<span>

</span><span>Solving:
</span>-12 + 20x = 48<span>

</span><span>Solving for variable 'x'.
</span>Move all terms containing x to the left, all other terms to the right.
<span>Add '12' to each side of the equation.
</span>-12 + 12 + 20x = 48 + 12<span>

</span>Combine like terms: -12 + 12 = 00 + 20x = 48 + 12
20x = 48 + 12<span>

</span><span>Combine like terms: </span>48 + 12 = 60
20x = 60<span>

</span><span>Divide each side by '20'.
</span>x = 3<span>

</span><span>Simplifying:
</span>x = 3<span>

Therefore, THAT is The Answer!^^^ 

</span>=====> x = 3 <=====
