Answer:

Step-by-step explanation:

Alright, lets get started.

Given that:

\frac{x+4}{4+x}

Using commutative property, 4+x = x+4,

so

\frac{x+4}{x+4}

Both numerator and denominator has same value, hence they could be cancelled.

So,

\frac{x+4}{x+4} = 1

Hence the answer is 1 :   Answer  

Hope it will help :)

If the sum of squares for a sample containing 51 items equals 200, what is the standard deviation?
Mashcka [7]

The standard deviation is 1.98. Option A is correct.

The standard deviation formula is given as

  • \sigma = \sqrt{\frac{SS}{n} }

where:

  • SS is the sum of squares = 200
  • n is the sample size = 51

Substitute the given parameters into the formula to have:

\sigma = \sqrt{\frac{200}{51} }\\\sigma = \sqrt{3.922}\\\sigma = 1.980

Hence the standard deviation is 1.98

Answer:

y - 6 = (-1/2)(x - 4)

Step-by-step explanation:

As we go from (4, 6) to (6, 10), x (the run) increases by 2 and y (the rise) increases by 4.  Thus, the slope of the line connecting these two points is m = rise / run = 4/2 = 2.

The slope of a line perpendicular to this one is the negative reciprocal of 2, which is -1/2.

Using the point-slope formula, we get the following equation for the perpendicular line:

y - 6 = (-1/2)(x - 4)   (  obtained using the point (4, 6)  )
