There are 4 king and 4 eight cards inside 52 one deck of cards. The case asks for a king card and then an eight card.
To draw the king card, you have 4/52 probability.
To draw the eight card, you have 4/51 probability ( since the king card not replaced).

The total probability would be: 4*4/ 52*51= 4/663

What does it mean when the ratio of person 1’s income to person 2’s incomes is 1 to 3 or 3 to 1? Explain.

viktelen [127]

Answer with explanation:

3:1 means that person 1's income is three times person 2's income.

E.g.: if person 1 gets 150 per hour, person 2 gets 30 per hour.

1:3 means that person 1's income is one third of person 2's income.

E.g.: if person 1 gets 40 per hour, person 2 gets 120 per hour.

Westkost [7]

Answer:

Perimeter of one of the triangle= $17.071 inch$

Step-by-step explanation:

The triangle has:

$Perpendicular= 5 inch\\Base = 5 inch \\Diagonal(Hypotenuse)=?$

Using the Pythagorean Theorem;

$( Hypotenuse)^2=(Perpendicular)^2+(Base)^2\\H^2= 5^2+5^2\\H^2=25+25\\H^2=50\\$

$H=\sqrt{50}\\or\\H=7.071 inches$

The Perimeter of one of the triangle is =

$Perpendicular+Base+Hypotenuse\\5+5+7.071\\17.071inch$

This is equal for the other triangle.
