What is the least common denominator of the fraction 7 over 3 x plus the fraction 2 over x plus the fraction x over x minus 1?

1 answer:

7 0

I didn't understand well the way you typed but I think that it is 7/3x + 2/x + x/x-1 , right? So the last common denominator is the one you can divide by all denominators and multiply by the nominator. So, it would be, if I understood well what you asked, 3x(x-1).

Using it's concept, the standard deviation of the data is of 3.742.

<h3>What are the mean and the standard deviation of a data-set?</h3>

The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.

The standard deviation of a data-set is given by the square root of the <u>sum of the differences squared between each observation and the mean, divided by the number of values</u>.

For this data-set, the mean is:

M = (1 + 4 + 4 + 4 + 4 + 6 + 5)/7 = 4.

Hence the standard deviation is:

$S = \sqrt{\frac{(1 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (6 - 4)^2 + (5 - 4)^2}{7}} = 3.742$

Answer:

(3l + (3)1.25) + 2m = 52.50

Step-by-step explanation:

(3l + (3)1.25) + 2m = 52.50

3*9.75 + 3.75 + 2*9.75

(29.25 + 3.75) + 19.50

33.00 + 19.50 = 52.50
