Answer:

P(A_1\ n\ A_2) = 0.40

Step-by-step explanation:

Let:

A_1 \to An Individual likes vehicle 1

A_2 \to An Individual like vehicle 2

P(A_1) = 0.55

P(A_2) = 0.65

P (A_1\ u\ A_2 ) = 0.80

Required

P(A_1\ n\ A_2) --- probability that both vehicles are liked by the individual.

This is calculated as:

P(A_1\ n\ A_2) = P(A_1) + P(A_2) - P(A_1\ u\ A_2)

So, we have:

P(A_1\ n\ A_2) = 0.55 + 0.65 - 0.80

P(A_1\ n\ A_2) = 0.40

The surface area of this regular pyramid is 1040 cm2. The base is a regular pentagon with side b = 16 cm and slant height l =15
Valentin [98]

Answer:

(a) = 11 cm

Step-by-step explanation:

The formula for finding the surface area of a regular pyramid is B + (1/2*P*l), with B being the area of the base, p being the perimeter of the base, and l being the slant of the pyramid.

The area of a pentagon can be solved using the formula 1/2*a*p, with a being the apothem and p being the perimeter of the pentagon.

  1. B + (1/2*80*15) = 1040
  2. B + 600 = 1040
  3. 1040 - 600 = 440 (440 is the area of pentagon)
  4. 1/2*a*(16*5) = 440
  5. 40*a = 440
  6. 440/40 = 11

The apothem is 11 cm. Hope this helps!
