54 + 6x = 822
6x = 768
x = 128
The probability of having at least 4 girls is 0.1875.
Shifting in the y direction is as simple as adding the shift, ie.,
f(x) = x+4.
In the x direction it is trickier because then you have to replace x by (x-a) where a is the shift to the right... (but that wasn't asked here).
Answer:
1.12 x 
Step-by-step explanation:
To solve, move the decimal back until you are past the 0s. It has to be moved back 4 times to get to the first 1.
1.12
Now, since you went back 4, the exponent of 10 is -4.
