Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The probability that the student knows the answer to the question is 
The probability that that the student will guess is 
The probability that that the student get the correct answer given that the student guessed is 
Here W denotes that the student gets the correct answer
Generally it a certain fact that if the student knows the answer he would get it correctly
So the probability the the student got answer given that he knows it is
Generally from Bayes theorem we can mathematically evaluate the probability that the student knows the answer given that he got it correctly as follows

Answer:
The price was reduced by about 53%
Step-by-step explanation:
Per cent of change = (amount of change) ÷ (original amount)
% change = (799.99 - 375.99)/799.99
= 424 / 799
= .5300
= 53 %
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
quick note:
the "x" must not have a negative coefficient for the standard form, though in this case it shows like so in the inappropriate choices above.
Answer:
36
Step-by-step explanation:
To get 1/4 of 48 we have to divide 48 by 4
48 ÷ 4 = 12
To get 3/4 of 48 we multiply 12 by 3
12 × 3 = 36
M=(y2-y1)/(x2-x1)
=[-1-(-4)] / (3-1)
=(-1+4) / 2
=3/2
