Answer:

A':A = 1742:7

Step-by-step explanation:

Applying,

A' = L'W'............... Equation 1

Where A' = Area of the window, L' = Length of the window, W' = Width of the window.

From the question,

Given: L' = 312 ft, W' = 134 ft

A' = (312×134)

A' = 41808 ft²

Similarly,

A = LW.................. Equation 2

Where A = Area of the image of the window, L and W is thw length and width of the image of the window

Given: L = 12 ft, W = 14 ft

Therefore,

A = 12×14

A = 168 ft²

Therefore the ratio of A' to A = 41808:168 = 1742:7

A':A = 1742:7

When randomly selecting an​ adult, A denotes the event of selecting someone with blue eyes. What do Upper P (Upper A )P(A) and U
bezimeni [28]

Answer:

P(A): It is the probability of selecting someone with blue eyes.  

P(\bar{A}): It is the probability of selecting someone who does not have blue eyes

Step-by-step explanation:

We are given the following in the question:

A: event of selecting someone with blue eyes.

Probability:

  • The probability of an event tells the chances of happening of that event.
  • It is mathematically defined as:

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

Complement of an event:

  • It is the event that consist of all outcomes not happening in A.
  • It is represented by \bar{A}
  • P(A) + P(\bar{A}) = 1

We have to explain the representation:

a) P(A): It is the probability of selecting someone with blue eyes.

It gives us the chances of someone having blue eyes.

b) P(\bar{A}): It is the probability of selecting someone who does not have blue eyes

It is the chances of selecting someone who does not have blue eyes.

Answer:

  57,001 cm², or 5.7 square meters

Step-by-step explanation:

The surface area of a cylinder is given by the formula ...

  A = 2πr(r +h)

  A = 2π(14 cm)(14 cm +40 cm) = 1512π cm²

Then 12 cylinders will have an area of ...

  12 × 1512π cm² = 18,144π cm² ≈ 57,001 cm²

Rui Feng wants to paint a total surface area of 57,001 cm², about 5.7 square meters.
