Answer:
The sidewalk is 34.5 inches wide.
Step-by-step explanation:
Given:
A sidewalk is built 12 bricks wide by laying each brick side by side.
Brick measures 2 7/8 inches wide.
Now, to find the width of sidewalk.
<em>Width of brick = 2 7/8 = 23/8.</em>
<em>Number of bricks = 12.</em>
So, the sidewalk = width of brick × number of bricks

Answer:
The probability of selecting an odd number given that the chip is black is 0.454.
Step-by-step explanation:
First of all, the value of probability is always less than 1, so the following value of probabilities need to be corrected and are:
Probability of selecting a black chip with an odd number(A)=0.415
Probability of selecting a black chip(B)= 0.915
Probability of A given B is denoted by=P(A | B)
P(A|B) =P(A∩B)/P(B)
P(B)=0.915
P(A∩B)=0.415
P(A|B)=
P(A|B)=0.454
The probability of selecting an odd number given that the chip is black is 0.454.
