Solve for a: b − 2a = c
vlada-n [284]

Answer:

a=-\frac{c-b}{2}

Step-by-step explanation:

Solving for the variable a, given that :

b-2a=c

We can first start start by subtracting b from both sides of the equation:

-2a=c-b

Now, we can divide both sides of the equation by the coefficient of a, which would be -2:

a=\frac{c}{-2}-\frac{b}{-2}

Applying the fraction rule \frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}:

a=\frac{c-b}{-2}

Then, apply the fraction rule \frac{a}{-b} =-\frac{a}{b}

a=-\frac{c-b}{2}

The mean value of 500 homes in a county is $225,000 and the standard deviation is $25,000. approximately how many of the homes i
dusya [7]

240 homes in the county are between $175,000 and $225,000.

The image attached is associated with this question and m in it refers to the mean value which is $225000 here and d refers to the standard deviation which is $25000 here.

Now since m= $225000

and $175000= $225000-$50000= $225000-(2* $25000)= m-2d

Thus, as per the image area covered between m and m-2d=  $225000

and $175000 is (34%+14%)of 500 homes= 68% of 500= 240 homes, is the answer.

A random variable X is said to follow a normal distribution if its parameters are mean and standard deviation. Every other distribution can be reduced to a normal distribution.
