Answer:

88.98% probability that a randomly selected car had automatic transmission or air conditioning or both

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

37 had automatic transmission only

44 had air conditioning only

61 had automatic transmission

This already counts those with both automatic transmission and air conditioning. So 61-37 = 24 had both.

So D = 37 + 44 + 24 = 105

Total outcomes:

118 cars sold, so T = 118.

What is the probability that a randomly selected car had automatic transmission or air conditioning or both?

p = \frac{D}{T} = \frac{105}{118} = 0.8898

88.98% probability that a randomly selected car had automatic transmission or air conditioning or both

The Great Pyramid of Giza is an example of a square pyramid and is the last
Verdich [7]

Answer:

The surface area of the pyramid is 466,137 squared cubits

Step-by-step explanation:

This is simply asking us to find the surface area of the square based pyramid with the given dimensions.

The first thing we need to know is the principle for finding the surface area of such pyramidal shapes. To get the surface area of a pyramid, we will have to add the base area to the area of the side faces ( lateral area)

The base area of the square based pyramid, will be the same as the area of a square which is = 453 cubits X 453 cubits =205209 cubits^{2}

The lateral area has already been given to us as 260,928 squared cubits.

The surface area of the pyramid is 260,928 + 205209 = 466137 squared cubits

Hence, the surface area of the pyramid is 466137 squared cubits

Answer:

x = 2

Step-by-step explanation:

The left side would be (3x - 12)
The right side would be (-4x+2)

In an equation, 3x - 12 = -4x+2

Combine all the letters on the left and plain numbers on the right,

3x + 4x = 12 + 2

Note: When you transfer to the other side of the equal sign, the number will change its sign.

Simplify the 3x + 4x = 12 + 2,

                     7x = 14

                      x=\frac{14}{7}

                      x = 2
