I think u should cut at tpo and the bottom so u will get triangle and a rectangle. Then u calculate the triangle part which is 1/2 x (17-7) x (22-10) = ?
Then u calculate the rectangle part L x B which is 10 x 17 = ? Then when you have the ans already, add them!

A deck of cards contains RED cards numbered 1,2,3 and BLUE cards numbered 1,2,3,4,5,6. Let R be the event of drawing a red card,

Tatiana [17]

Answer:

e. R′

Step-by-step explanation:

Let the Sample Space be a universal set consisting of 3 red and 6 blue cards. Then the event of of getting 4 blue cards will be given

R complement = R` = Universal Set minus Red cards will give blue cards.

a. R OR O

It cannot be this option because we need 4 blue card

b. B AND O

It cannot be this choice as well because 4 is not odd.

c. R OR E

4 is even but we need blue

d. R AND O

Red and odd is again not required

e. R′ = It will give our required result.

f. E′= 4 is even if it is complemented it cannot be obtained and will be left out.

Answer:

2x -y ≥ 4

Step-by-step explanation:

The intercepts of the boundary line are given, so it is convenient to start with the equation of that line in intercept form:

... x/(x-intercept) + y/(y-intercept) = 1

... x/2 + y/(-4) = 1

Multiplying by 4 gives the equation of the line.

... 2x -y = 4

This line divides the plane into two half-planes. The half-plane that is shaded is the one for larger values of x and/or smaller values of y than the ones on the line. So, for some given y, if we increase x we will get a number from our equation above that is greater than 4. Hence, the inequality we want is ...

... 2x -y ≥ 4

We use the ≥ symbol because the line is solid, so part of the solution space.
