Mathematics

"Percent" or "%" means "out of 100" or "per 100", Therefore 83% can be written as <span>83<span>x100</span></span>.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for n while keeping the equation balanced:

<span>n=<span>83100</span>×200</span>

<span>n=<span>16600100</span></span>

<span>n=</span>

<span>166
</span><span>83% of 200=166

</span>

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day.
WITCHER [35]

The minimum sample size required to estimate the mean usage of water = 2225.07

What is Standard deviation?

In statistics, the standard deviation (SD, also represented by the Greek letter sigma σ or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.

We can find the minimum sample size required to estimate the mean usage of water as shown below:

Standard deviation \sigma =3.61

Margin of error E=0.15

Critical value for 95% confidence interval = 1.96

Required minimum sample size: n=(\frac{Z_{\frac{\alpha}{2}}.\sigma }{E} )^2

=(\frac{1.96\times 3.61}{0.15} )^2

=2225.07

Hence, the minimum sample size required to estimate the mean usage of water = 2225.07

What’s a larger number is two less than four times a smaller. if the sum of the number is 18
s344n2d4d5 [400]
Let x be the larger number and y be the smaller number.
Using the given info, we get
x = 4y - 2
We also know that 
x + y = 18
Substitute x = 4y -2 into x + y = 18
(4y -2) +y = 18
5y - 2 = 18
5y = 20
y = 4
Enter this value into x = 4y - 2
x = 4(4) - 2
x = 14
The larger number is 14 and the smaller one is 4.

Solve for x in the first equation, then solve the system using substitution. Write your answer as (x, y).
OleMash [197]
2x - 6y = 14
2x = 6y + 14
x = 3y + 7.....so sub in 3y + 7 for x in the other equation

4x - y = 9
4(3y + 7) - y = 9
12y + 28 - y = 9
12y - y = 9 - 28
11y = - 19
y = -19/11

x = 3y + 7
x = 3(-19/11) + 7
x = -57/11 + 7
x = -57/11 + 77/11
x = 20/11

solution is : (20/11, -19/11) <==
