Good morning

Answer:

Surface area (rounded to the nearest tenth) = 193.3 in²

Step-by-step explanation:

Surface area of this prism = 2×(base’s area) + lateral area

base’s area = (1.9 × 7)/2 = (1,9×7)÷2 = 6.65

lateral area = 12×(7+3+5) = 180

then

Surface area of this prism = 2×(base’s area) + lateral area

= 2×(6.65)+180

= 193.3

What is the area of the trapezoid ?

Helga [31]

Answer:

Step-by-step explanation:

The formula of an area of a trapezoid is:

$A=\dfrac{b_1+b_2}{2}\cdot h$

b₁, b₂ - bases

h - height

We have:

b₁ = 20 ft, b₂ = 16 ft, h = 24 ft

Substitute:

$A=\dfrac{20+16}{2}\cdot24=\dfrac{36}{2}\cdot24=18\cdot24=432\ ft^2$

The probability that Paul wins in a raffle is given by the expression

AnnZ [28]

Answer:

$1 - p$

Step-by-step explanation:

Consider the $(\Omega, \mathcal{F}, \mathbb{P})$ where $\mathcal{F}$ is sigma algebra and $\mathbb{P}$ is probabilistic measure. Denote $A \subset \Omega$ where Paul wins. By additivity of measure we know that

$\mathbb{P}(A) + \mathbb{P}(\Omega \setminus A) = \mathbb{P}(\Omega) = 1$ .

$\mathbb{P}(\Omega \setminus A) = 1 - \mathbb{P}(A) = 1 - p$ .

But $\Omega \setminus A$ is exactly the set where Paul does not win. Q.E.D.
