1,080×(1−0.03)^(6)
=899.6 per month round your answer to get 900
Plug in what we know:
Find the cube root of both sides:
![\sf~a=\sqrt[3]{2744}](https://tex.z-dn.net/?f=%5Csf~a%3D%5Csqrt%5B3%5D%7B2744%7D)
Simplify:
Answer:
(x+1)2+(y−2)2=5
Explanation:
The general form for a circle with center
(a,b) and radius r is XXX(x−a)2+(y−b)2=r2
With center (−1,2) and given that (0,0) is a solution (i.e. a point on the circle),according to the Pythagorean Theorem: XXX r 2=(−1−0)2+(2−0)2=5
and since the center is (a,b)=(−1,2)by applying the general formula we get:XXX(x+1)+(y−2)2=5
Step-by-step explanation:
its already in the answer
She began with 10. She has 11. Take away the 6 she just bought and that leaves 5. But she had sold half and ended up with 5. So she started with 10!
Answer:
1. 0.0000454
2. 0.01034
3. 0.0821
4. 0.918
Step-by-step explanation:
Let X be the random variable denoting the number of passengers arriving in a minute. Since the mean arrival rate is given to be 10,
1. Requires us to compute
2. We need to compute 
3. The expected no. of arrivals in a 15 second period is = 
. So if Y be the random variable denoting number of passengers arriving in 15 seconds,
4. Here we use the fact that Y can take values 
. So, the event that "Y is either 0 or 
1" is a sure event ( i.e it has probability 1 ).
