What is the definition of Standard Deviation?

Mathematics
1 answer:
aleksandrvk [35]3 years ago
6 0

Answer:

b.  Square root of the variance

Step-by-step explanation:

The standard deviation measure how scattered the data of the set is, in other words, measure the dispersion. A low value is found when the points are close to the mean, and when the value is high the data uses a wider range of values. To calculate its value, the simple way, you need the variance because the standard deviation is the square root of the variance.

Which is the equation of a line that has a slope of -2/3 and passes through point (-3,-1)?
Fantom [35]

Answer:


Step-by-step explanation:

You have to use Point Slope Form:

  • y - Y1 = m (x - X1)
  • m is the slope
  • Y1 & X1 is a point on the line
  • The form allows you to identify the slope & the point on the line

About Problem:

  • Since -2/3 is the slope, it represents m in y - Y1 = m (x - X1) form.
  • -3 represents X1 in y - Y1 = m (x - X1) form
  • -1 represents Y1  in y - Y1 = m (x - X1) form

y - Y1 = m (x - X1)

y - -1 = -2/3 (x - -3)  ---- This is in Point Slope Form

If you want to solve it, & put it in Slope Intercept form, it would look like this:

y = mx + b

y = -2/3 - 2 --- This is in Slope intercept Form.... I might've solved it wrong... I'm not sure...


Really really sorry if I'm incorrect...

If a baseball game lasted 3 1/4 hours and ended at 10 P.M. , at what time did they start
Orlov [11]
Subtracting 3.25 hours from 10 PM is subtracting 3 hours and 15 minutes from 10 PM. Doing this, we get that the game started at 6:45 P.M. Hope this helped!
