The answer is $1.05 but this is only right if the posters cost the same amount as the markers.
<em>a</em> = 8 - a train arrives at the station once every 8 minutes, so for any given 8 minute interval, a randomly selected train has uniform probability of arriving at the station at some point in this time.
<em>f(x)</em> = 1/8 - the area under the graph of <em>f(x)</em> must be equal to 1. This area corresponds to a rectangle with length <em>a</em> = 8 and height <em>x</em> such that 8<em>x</em> = 1. Solving for <em>x</em> gives 1/8.
<em>P</em> = 5/8 - this is equal to the area under the graph over the interval [0, 5], which is the area of a rectangle with length 5 and height 1/8.
Answer:
1.39/1
Step-by-step explanation:
the answer can be explained by dividing the distance covered by thebiker to the number of laps covered by the same. This gives us the ratio of distance per unti lap for the biker.
11.12 miles divided by 8 gives us= 1.39
For the first question: All you have to do is count the rectangles! So, not including the shaded rectangle, there are 14 that are equal in size. (If your teacher wants you to include the shaded rectangle in your answer, it is 15.)
For the second question: You just have to put the number of shaded rectangles (1) as the top number, or numerator. Then, you put the total number of rectangles as the bottom number, or denominator (15), to get you an answer if 1/15 of the square.
For the third question: the area of the square is 1 meter, so the fractional answer would just be 1/1. You could do it with the rectangles, too, and get 15/15 which reduces to 1/1 as your final answer.
Hope this helps! Good luck!
Answer: 0.0668
Step-by-step explanation:
As per given description, we have
n= 36
Let x be a random variable that represents the weight of boxes.
z-score : 
For x= 84 lb , we have
P-value : 
Hence, the probability that the average weight of the boxes will be less than 84 lbs. = 0.0668
