The required probability of giving class period run between 51.5 and 51.75 is 0.125.
The lengths of her classes are uniformly distributed between 50 and 52 minutes.
<h3>What is the probability?</h3>
Probability, can be define as the ratio of favorable events to the n number of total events.
since,
p(r) = 0.125
Thus, the required probability of class period runs between 51.5 and 51.75 is given by 0.125

Number of pencils bough by the student = 84
Number of pencils sharpened by the student = 35
Then
The number of pencils that was not sharpened = (84 - 35)
= 49
So 35 pencils have been sharpened and 49 pencils have not been sharpened.
Then Number of pencils unsharpened:Number of pencils sharpened = 49:35
= 7:5
So the ratio of the number of unsharpened pencil to the number of sharpened pencil is 7:5
The second answer is correct
x+y=2 x^2+y^2=-1 x^2+y<span>^2=1 (x-4)^2+(y-2)^2=0 </span>
Answer: 100c +34
Step-by-step explanation: I believe you add 88c and 12c together which simplifies the expression to 100c + 34 in total cost.
