the mean of a set of numbers is 300. if each number in that set is increased by 5, what is the new mean of this new set of numbe
Vilka [71]

The new mean of set of new numbers is 305

<u>Solution:</u>

Given, The mean of a set of numbers is 300  

Each number in that set is increased by 5,  

We have to find what is the new mean of this new set of numbers

\text { mean }=\frac{\text { sum of observations }}{\text { number of observations }}

Now, let the number of observations be n and observations be a_{1}, a_{2}, a_{3}, a_{4}, \ldots \ldots \ldots, a_{n}

\text { So, mean }=\frac{a_{1}+a_{2}+a_{3}+\cdots a_{n}}{n}

a_{1}+a_{2}+a_{3}+\ldots \ldots+a_{n}=m e a n \times n

a_{1}+a_{2}+a_{3}+\ldots . a_{n}=300 n

Now, after each number is increased by 5

\text { New numbers are }\left(a_{1}+5\right),\left(a_{2}+5\right), \ldots \ldots \ldots\left(a_{n}+5\right)

\text { And, new mean }=\frac{\text {sum of new observations}}{\text {number of observations}}

=\frac{\left(a_{1}+5\right)+\left(a_{2}+5\right)+\ldots \ldots+\left(a_{n}+5\right)}{n}

=\frac{\left(a_{1}+a_{2}+\cdots a_{n}\right)+(5+5+5+\cdots+5(n\text { times)) } }{n}

=\frac{300 n+5 n}{n}=\frac{305 n}{n}=305

Hence, the new mean is 305

Aleonysh [2.5K]
Fist find the slope. The equation is m=y2-y1/x2-x1. Then use slope point form and select a point. Then use the equation y-y1=m(x-x1). Simplify and isolate y.
