The given statement about Trapezoid is

"A quadrilateral is a trapezoid if and only if it has exactly one pair of parallel sides."

Other Quadrilaterals, Parallelogram, Rhombus, Square, Rectangle and Kite can be also Called as Trapezoid.

Trapezoid is special name given to Quadrilateral which has only a single pair of Parallel sides.

Out of given options ,the correct Statement is

Option A: A trapezoid has exactly one pair of parallel sides if and only if it is a quadrilateral.

Find a quadratic model for the set of values: (-2, -20), (0, -4), (4, -20). Show your work.

Ivahew [28]

Ok... so this question can be solved by using simultaneous equations.

Use the general from of a parabola

$y = ax^2 + bx + c$

you know the value of c, the y-intercept... y = -4

which means the equation is

$y = ax^2 + bx - 4$

now use the other 2 points to get 2 equations in 2 unknowns

(-2, -20) just substitute

$-20 = (-2)^2a + (-2)b - 4 ~~~or~~~ -20 = 4a - 2b - 4$

this becomes

$4a - 2b = -16$

now the other equation using (4, -20)

The simplified form is

Which of the following equations represents the line that is graphed on the coordinate grid below

vladimir2022 [97]

Answer:

Step-by-step explanation:

the factor of x in the equation is the slope, which is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

going from the left point to the right point x changes by +3 units, and y changes by -1 unit.

so, the slope (and factor of x in the equation) is -1/3.

and the constant term in the equation is the y (axis) intercept of the line.

this is the y value, when x = 0 (intercepting the y axis).

and we see in the graph, when x = 0, the line goes through y = 2.

so, the equation has to be

y = -1/3 × x + 2

therefore, C is the right answer.

A graduate student wanted to estimate the average time spent studying among graduate students at her school. She randomly sample

expeople1 [14]

Answer:

B. The width of the confidence interval would be smaller.

Step-by-step explanation:

By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.

Therefore, the answer is B. The width of the confidence interval would be smaller.
