1.) Given P(E or F) = 0.82, P(E) = 0.18, and P(E and F) = 0.09, what is P(F)?
dangina [55]

Answer:

p(F)=0.73

Step-by-step explanation:

we have by identity

p(A\cup B)=p(A)+p(B)-p(A\cap B)

Thus for given events E and F

we havep(E\cup F)=p(E)+p(F)-p(E\cap F)

Applying values we get

p(F)=p(E\cup F)+p(E\cap F)-p(E)

Thus

p(F) = 0.82+0.09-0.18

p(F) = 0.73

Hillary is planning an expensive surprise party. She is choosing between two venues. The banquet hall at Hotel A will cost $431
In-s [12.5K]

Answer: Hillary would have to invite 15 people before the cost of having the party at Hotel B is less than the cost of having a party at Hotel A

Step-by-step explanation:

Let x represent the number of guests that Hillary would invite.

The banquet hall at Hotel A will cost $431 to rent the room and $38 per guest. This means that the total cost of hosting x guests at hotel A is

38x + 431

The banquet hall at Hotel B will cost $747 to rent the room and $16 per guest. This means that the total cost of hosting x guests at hotel B is

16x + 747

For the cost of having the party at Hotel B to be less than the cost of having a party at Hotel A, it means that

16x + 747 < 38x + 431

747 - 431 < 38x - 16x

316 < 22x

22x > 316

x > 316/22

x > 14.36

10. what is the volume of the prism to the nearest whole unit?
Ainat [17]
To calculate the volume of the rectangular prism and the triangular prism you will multiply the area of the base by the height of the prism.

1.  V = BH
     V = lwH
           12 x 8 x 4
     V = 384 cubic inches

2.   V = BH
      V = 1/2bhH
            1/2 x 12 x 2 x 18
      V = 216 cubic feet
