I think you need only an answer without expanation so let's start.
a)
![P = \frac{200!}{180!x20!} * 0,1^{20}*0,9^{180} = 0.093636](https://tex.z-dn.net/?f=P%20%3D%20%20%5Cfrac%7B200%21%7D%7B180%21x20%21%7D%20%20%2A%200%2C1%5E%7B20%7D%2A0%2C9%5E%7B180%7D%20%3D%200.093636%20)

7y-1=-8
7y=-8+1
y=-7/7
y=-1
Answer:area=l×b
10×8=80cm* 2
perimeter =(l+b)2
10+8)*2
18×2
=36cm
Step-by-step explanation:
The simplified version of -28/7 would be -4
At the end of the third day, the new reading on the odometer will be 12,578 mi
<h3>
What will the odometer reading at the end of the third day?</h3>
The initial odometer reading is 12,386 miles.
Then, the driver takes drives to and from work, such that each trip is 32 miles. Then each day he drives 2*2mi = 64 miles.
And he does this for 3 days, then the total distance driven is:
3*64mi = 192 miles.
At the end of the third day, the new reading on the odometer will be:
R = 12,386 mi + 192mi = 12,578 mi
