<span>A Smart Card refers to the integrated circuit chip on the card - that's the small square or round chip usually seen on the face of the card. This is used on both debit and credit cards to deliver encrypted authentication for the card when it is used in an shop at an electronic data capture machine (POS terminal), or at an ATM. The chip helps to prevent fraud and reduces the risk of a card’s data being duplicated.</span>

Answer:

Janninne made 68% then 3/25 turned into percentage 12% then 0.2 equals 20%. So you order it by 68% (Janinee), 20% (Kathy), AND 12% (Monique)

The bases of a trapezoid lie on the lines y=2X +7 and y= 2X -5. Write the equation that contains the midsegment of the trapezoid

ryzh [129]

Given:

The bases of a trapezoid lie on the lines

$y=2x+7$

$y=2x-5$

To find:

The equation that contains the midsegment of the trapezoid.

Solution:

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

On comparing $y=2x+7$ with slope intercept form, we get

$m_1=2,b_1=7$

On comparing $y=2x-5$ with slope intercept form, we get

$m_2=2,b_2=-5$

The slope of parallel lines are equal and midsegment of a trapezoid is parallel to the bases. So, the slope of the bases line and the midsegment line are equal.

$m=m_1=m_2=2$

The y-intercept of one base is 7 and y-intercept of second base is -5. The y-intercept of the midsegment is equal to the average of y-intersects of the bases.

$b=\dfrac{b_1+b_2}{2}$
