If Five hundred ten of 650 high school students said that pizza was their favorite food. The margin of error is 0.0322.

<h3>Margin of error</h3>

Given:

Sample proportion=Five hundred ten=510

Sample size=650

Hence:

Margin of error=z×√p×(1-p)/n

Margin of error=2√510/650× (1-510/650)÷650

Margin of error=2√0.78461538×(1-0.78461538)÷650

Margin of error=2√0.78461538×0.21538462÷650

Margin of error=2√0.168994085÷650

Margin of error=2√0.0002599909

Margin of error=0.0322

Therefore the correct option is D.

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. Determine each segment length in right triangle .

Pani-rosa [81]

The segment length is 14 (square root)2

Given that Triangle ABC is right angle triangle

The vertex marked is B where side AC is the hypotenuse

The side of AC is at Vertex B is 14

The dash segment from vertex B to point D on side AC

Angle BDA is marked right angle .

Angles A and C both marked 45 degrees.

As shown in diagram

Triangle ABC is drawn according to the statement where B is vertex

The side lengths are 14

Now to find Another side length that is x

So , the equation formed is

x*cos45 = 14

x/√2 = 14

x = 14√2

Hence the length of the segment is 14√2

Question 31 (Essay Worth 5 points)

For this case we have by definition, that the derivative of the position with respect to time is the velocity, that is to say:

$\frac {d (s (t))} {dt} = v (t)\\\frac {d (6-14t)} {dt} = v (t)$

So:

Taking into account that the derivative of a constant is 0.

$\frac {d (6-14t)} {dt} = 0- (1 * 14 * t ^ {1-1}) = 0- (14 * t ^ 0) = - 14$

So, the velocity is -14

Answer:

-14
