Answer: c) 0.75
Step-by-step explanation:
Given : The probability of choosing a black marble is P(Black)= 0.36.
The probability of choosing a black and then a white marble is P( Black and white) = 0.27.
Then by conditional probability ,
The probability of the second marble being white if the first marble chosen is black = 
Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75
Answer:
460 mi²
Step-by-step explanation:
The surface area consists of 3 rectangles of the sides, and the two base triangles.
The front rectangle has dimensions of 10x11, so it's area is 110 in²
The left side rectangle has dimensions of 10x11, so it's area is 110 in²
The right side rectangle has dimensions of 12x11, so it's area is 132 in²
The top and bottom triangles have a base of 12 and a height of 8, so their area is
A = (1/2)(12)(8) = 108/2, but there are 2 of them, so their combined area is (108/2)(2) = 108 in²
The total surface area is 110 + 110 + 132 + 108 = 460 mi²
Irrational numbers are numbers that can not be written as a simple fraction. An example of one would be 
. Pi is about 3.14, but it goes on forever. You can not write pi as a simple fraction.
Answer:
When an object has been transformed, its image can again be transformed to form a new image. Such transformation is called a combination of transformations. After a combination of transformations, the change from the single object to the final image can be described by a single transformation.
