Answer:E. (126 + 10.5x) square feet
Step-by-step explanation:
The length of the living room is 12 feet.
The width of the living room is
10 1/2 feet = 10.5 feet.
The length of the room is being expanded by x feet. This means that the new length of the room would be
12 + x = (12 + x) feet
The formula for determining the area of a rectangle is expressed as
Area = L × width.
Therefore, an expression to represent the new area of the living room in square feet and the expanded form of the expression would be
Area = 10.5(12 + x)
Area = 126 + 10.5x
Answer:
The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.
Step-by-step explanation:
let S be the sample space for the inspection of the light bulbs.
Therefore, n(s) = 800
let ' A ' be the event of no defects bulbs.
Therefore, n(A) = 796
Now the Experiment probability for a light bulb chosen has no defects will be given by,
Substituting the values we get
The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.
Answer:
They all have a solution of 3.
Step-by-step explanation:
Each of the equations represented are basically the same thing, therefore have the same answer.
A) 2r = 6 - You would divide 6 by 2 and you would get 3.
B) 6 = 2r - You would still divide 6 by 2, which equals 3.
C) 2r = 6 - Then again you would divide 6 by 2 to get 3.

Answer:
Pr(blue) = 1/2, Pr(white) = 1/6, Pr(red) = 1/3
Step-by-step explanation:
1 white,
3 blue, and
2 red marbles
Total marbles = 1+ 3 + 2 =6
Probability of picking blue = number of blue ➗ total number of marbles
Pr(blue) = 3/6
Divide both by 3 to make the fraction to the lowest term.
Pr(blue) = 1/2
Probability of picking white = number of white ➗ total number of marbles
Pr(white) = 1/6
Probability of picking red = number of red ➗ total number of marbles
Pr(red) = 2/6
Divide both by 2 to make the fraction to the lowest term.
Pr(red) = 1/3
