Step-by-step explanation:
Represent the probability that a graduate finds a job with p
![p = 55\%](https://tex.z-dn.net/?f=p%20%3D%2055%5C%25)
Required
Determine the probability that at least 1 of 7 gets a job.
In probability:
![P(At\ least\ 1) = 1 - P(None)](https://tex.z-dn.net/?f=P%28At%5C%20least%5C%201%29%20%3D%201%20-%20P%28None%29)
So, we calculate the probability that none of the 7 gets a job.
Represent the probability that a graduate will not get a job with q.
![q= 1 - p](https://tex.z-dn.net/?f=q%3D%201%20-%20p)
![q= 1 - 55\%](https://tex.z-dn.net/?f=q%3D%201%20-%2055%5C%25)
![q=45\%](https://tex.z-dn.net/?f=q%3D45%5C%25)
Represent as decimal
![q = 0.45](https://tex.z-dn.net/?f=q%20%3D%200.45)
The probability that none of the 7 will get a job is ![q^7](https://tex.z-dn.net/?f=q%5E7)
i.e.
![P(None) = q^7](https://tex.z-dn.net/?f=P%28None%29%20%3D%20q%5E7)
So, we have:
![P(At\ least\ 1) = 1 - P(None)](https://tex.z-dn.net/?f=P%28At%5C%20least%5C%201%29%20%3D%201%20-%20P%28None%29)
![P(At\ least\ 1) = 1 - q^7](https://tex.z-dn.net/?f=P%28At%5C%20least%5C%201%29%20%3D%201%20-%20q%5E7)
Substitute 0.45 for q
![P(At\ least\ 1) = 1 - 0.45^7](https://tex.z-dn.net/?f=P%28At%5C%20least%5C%201%29%20%3D%201%20-%200.45%5E7)
![P(At\ least\ 1) = 1 -0.00373669453](https://tex.z-dn.net/?f=P%28At%5C%20least%5C%201%29%20%3D%201%20-0.00373669453)
![P(At\ least\ 1) = 0.99626330547](https://tex.z-dn.net/?f=P%28At%5C%20least%5C%201%29%20%3D%200.99626330547)

Answer:
Hi, the answer is a.
Step-by-step explanation:
1. 1800-200=1600
2. As 1800 is total x will be smaller amount. so....
3. when we write a subtraction statement bigger number - smaller number..
4. So answer will be 1600-x

Answer:
81 x y^5
Step-by-step explanation:
Simplify the following:
9×3×3 x y^4 y
3×3 = 9:
9×9 x y^4 y
9 x y^4×9 y = 9×9 x y^(4 + 1):
9×9 x y^(4 + 1)
4 + 1 = 5:
9×9 x y^5
9×9 = 81:
Answer: 81 x y^5
