Answer:
No
Step-by-step explanation:
Cross multiplying shows this is false.
Answer:
![y = 160000 * (1.08)^t](https://tex.z-dn.net/?f=y%20%3D%20160000%20%2A%20%281.08%29%5Et)
Step-by-step explanation:
Given

Required
The function over time
The function is calculated as:
![y = a(1 + r)^t](https://tex.z-dn.net/?f=y%20%3D%20a%281%20%2B%20r%29%5Et)
So, we have:
![y = 160000 * (1 + 8\%)^t](https://tex.z-dn.net/?f=y%20%3D%20160000%20%2A%20%281%20%2B%208%5C%25%29%5Et)
Express percentage as decimal
![y = 160000 * (1 + 0.08)^t](https://tex.z-dn.net/?f=y%20%3D%20160000%20%2A%20%281%20%2B%200.08%29%5Et)
![y = 160000 * (1.08)^t](https://tex.z-dn.net/?f=y%20%3D%20160000%20%2A%20%281.08%29%5Et)
Answer: The measures of the angles are 64.6 degrees and 25.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees.
x can be one angle, and (x-39.2) can be the other
x + (x-39.2) = 90
2x - 39.2 = 90
add 39.2 to both sides
2x = 129.2
divide each side by 2
x = 64.6
find the measure of the other angle
64.6-39.2 = 25.4
The measures of the angles are 64.6 degrees and 25.4 degrees.
Answer:
The probability is ![P(X > 20 ) = 0.8](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%200.8)
Step-by-step explanation:
From the question we are told that
The closing price of Schnur Sporting Goods Inc. common stock is uniformly distributed between $18 and $28 per share.
Given that the stock is uniformly distributed then the probability that the stock price will be more than $20 is mathematically evaluated as
![P(X > 20 ) = 1 - P(X < 20 )](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%201%20-%20P%28X%20%3C%2020%20%20%29)
Since it is uniformly distribute between $18 and $28 per share then we can solve is as follows
=> ![P(X > 20 ) = 1 - [\frac{ 20 - 18 }{28 -18} ]](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%201%20-%20%5B%5Cfrac%7B%2020%20-%20%2018%20%7D%7B28%20-18%7D%20%5D)
=> ![P(X > 20 ) = 0.8](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%200.8)
