Answer:
Step-by-step explanation:
There is a 1/12 probability that volume 1 will be correctly put in position 1.
If we assume that volume 1 is right, then since there are then only 11 books left to choose from, there is then a 1/11 prob that volume 2 will be in position 2. And so on. By the same reasoning there is 1/10 prob that volume 3 is then right, 1/9 prob for volume 4, 1/8 prob for volume 5, and 1/7 prob for volume 6,
and 1/6 prob for volume 7,and 1/5 prob for volume 8,and 1/4 prob for volume 9,and 1/3 prob for volume 10,and 1/2 prob for volume 11,and 1/1 prob for volume 12.
So the probability is 1 /(12*11*10*9*8*7*6*5*4*3*2*1) = 1 / 479,001,600 ....

Step-by-step explanation:
Answer:
10 = -2(7) +24
Step-by-step explanation:
or
y = -2 (7) +24
first, we find the negative reciprocal of the slope of the first equation.
1/2 = -2/1 = -2
So the slope for the new equation will be -2
y = -2x+b
Now we know it will pass through the point (7,10)
So the x coordinate will become x, and the y coordinate will become y
10= -2(7) +b
-2 x 7 = -14 + b = 10
-14 -10 = -24
so
b = 24
because
-14 + 24 = 10
So our final equation(s) are
y = -2(7) +24
or
10 = -2 (7) + 24
I’ve attached my work
b is your answer
I just drew a sketch of a graph and saw if it would be a line
