Well in area you multiply and perimeter you add, so right now you are multiplying the measures of the triangle, So you can either write out the problem and solve it or use a calculator to get you answer, but I would say to solve it because you never if the calculator could be wrong, so if you wanna write it out then you write 9 then put the 14 under it and put the 5 under 14 but under the 4 of 14, so basically you are just going to multiply 9 by 14 to get 126 then multiply 126 by 5 to get 630, so now 630 is your final answer

Answer:

  b.  55°

Step-by-step explanation:

Complementary angles have a sum of 90°.

  ∠ABC +∠CBD = 90° . . . . . . the given relation

  ∠ABC + 35° = 90° . . . . . . . . . substitute the given value

  ∠ABC = 55° . . . . . . . . . . . . . . subtract 35° from both sides

  ∠ABC = ∠EBF = 55° . . . . . . vertical angles are congruent

According to a survey of 100 people regarding their movie attendance in the last year, 40 had seen a science fiction movie, 55 h
erastovalidia [21]

Answer:

The probability that at least one movie had seen P(S∪(AD)∪H) = 0.75

Step-by-step explanation:

The total number of movie attendance in the last year n =100

Let 'S' be the event had seen science fiction movie

The probability of that the event had seen science fiction movie

P(S) = 40/100 = 0.4

Let 'AD' be the event had seen adventure  movie

the probability of that  the event had seen adventure  movie

P(AD) =55/100 = 0.55

Let 'H' be the event had seen Horror movie

The probability of that the event had seen Horror movie

P(H) =20/100 = 0.2

given data 25 had seen a science fiction movie and an adventure movie

The probability of that the seen a science fiction movie and an adventure movie

that is P(S∩(AD)) = 25/100=0.25

Given  5 had seen an adventure movie and a horror movie

The probability of that the seen adventure movie and a horror movie

That is P((AD)∩ H) = 5/100=0.05

Given  5 had seen an science movie and a horror movie

The probability of that the seen science movie and a horror movie

That is P((S∩ H) = 15/100=0.15

Given only 5 people had seen a movie from all three categories.

The probability of that the seen a movie from all three categories.

That is P(S∩(AD)∩H) =5/100=0.05

The probability that at least one movie had seen P(S∪(AD)∪H) =

              =  P(S)+P(AD)+P(H) - P(S∩(AD)-P((AD)∩ H)-P((S∩ H) + P(S∩(AD)∩H)

              = 0.4+0.55+0.2-0.25-0.05-0.15+0.05

              = 0.75
