Answer:
The required probability is ![\frac{19}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B40%7D)
Step-by-step explanation:
The probability of obtaining a defective item from container 1 is ![P(E_1)=\frac{3}{8}](https://tex.z-dn.net/?f=P%28E_1%29%3D%5Cfrac%7B3%7D%7B8%7D)
The probability of obtaining a good item from container 1 is ![P(E_1)=\frac{5}{8}](https://tex.z-dn.net/?f=P%28E_1%29%3D%5Cfrac%7B5%7D%7B8%7D)
The probability of obtaining a defective item from container 2 is ![P(E_1)=\frac{2}{5}](https://tex.z-dn.net/?f=P%28E_1%29%3D%5Cfrac%7B2%7D%7B5%7D)
The probability of obtaining a good item from container 2 is ![P(E_1)=\frac{3}{5}](https://tex.z-dn.net/?f=P%28E_1%29%3D%5Cfrac%7B3%7D%7B5%7D)
The cases of the event are
1)Defective item is drawn from container 1 and good item is drawn from container 2
2)Defective item is drawn from container 2 and good item is drawn from container 1
Thus the required probability is the sum of above 2 cases
![P(Event)=\frac{3}{8}\times \frac{3}{5}+\frac{5}{8}\times \frac{2}{5}=\frac{19}{40}](https://tex.z-dn.net/?f=P%28Event%29%3D%5Cfrac%7B3%7D%7B8%7D%5Ctimes%20%5Cfrac%7B3%7D%7B5%7D%2B%5Cfrac%7B5%7D%7B8%7D%5Ctimes%20%5Cfrac%7B2%7D%7B5%7D%3D%5Cfrac%7B19%7D%7B40%7D)
Answer: A = $1503.6
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 1000
r = 6% = 6/100 = 0.06
n = 1 because it was compounded once in a year.
t = 7 years
Therefore,.
A = 1000(1 + 0.06/1)^1 × 7
A = 1000(1.06)^7
A = $1503.6
Answer: No
Step-by-step explanation: For x 0-2, the y is increasing by +5 every time. However, the moment it hits x=2, it starts decreasing by -5 every time. This means that it does not follow on set pattern (either +5 or -5) and looks more like a ^ than a /.
Answer:
X should equal 65, sorry if I’m wrong
