How does an open question differ from a closed question?
Answers a question with a question.
Open ended class within the frequency distribution?
If, in a frequency distribution, the initial class interval is indeterminate at its beginning and/or the final class interval is indeterminate at its end, the distribution is said to possess "open ended" classes.
Why are open-ended frequency distributions necessary?
to quickly and effectively represent data
What is Confidence Intervals of Interval Estimate?
An open interval centered about the point estimate, .
In which class either lower limit or upper limit is missing?
open end class
Which way does a parabola open when the coefficient of its y2term a is negative?
Nose points right, opens to the left.
Which way does a parabola open when the coefficient of its x2 term a is positive?
It is like the letter U.
Given the standard equation for a parabola opening left or right which way does a parabola open when the coefficient of the y2-term a is positive?
right
Which way does a parabola open when the coefficient of its x2term a is positive?
Upwards: it is cup shaped, not cap shaped.
Given the standard equation for a parabola opening left or right which way does a parabola open when the coefficient of the y2-term a is positive Left or right?
left
When does a parabola open down?
No, a parabola is the whole curve, not just a part of it.
Which way does a parabola open when the coefficient of its x2term a is negative?
DOWN!
What do you call the graph of a quadratic equation?
A PARABOLA. If the coefficient of 'x^(2)' is positive (+), then the parabola is 'bowl' shaped. If the coefficient os 'x^(2)' is negative (-), then the parabola is 'umbrella' shaped. This shape of parabola has the general eq'n of y = (+/-) ax^(2( + bx + c For a parabola lying on its side ; open side to the right, then the general eq'n is ; y^(2) = 4ax.
Which way does a parabola open when the coefficient of its y2-term is negative?
LEFT
Which way does a parabola open when the coefficient of its y2-term, a, is positive?
Open to the right. Like the sign for a proper subset, or a rounded version of the less than symbol, <.
if the parabola open upward a is?
positive.
Given the standard equation for a parabola opening up or down which way does a parabola open when the coefficient of the x2term a is negative Up or down?
down
