If line p has a slope of 4/7, what is the slope of a line perpendicular to p? (1). 4/7
(2). 7/4
(3). -4/7
(4). -7/4

-7/4

Step-by-step explanation:

When you find the perpendicular slope, you take the opposite reciprocal of the original slope. For 4/7, the opposite is -4/7, and the reciprocal of that is -7/4.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

two data sets with the same median will not have the same varaibility
