Answer:just got it right!
Step-by-step explanation:
Answer:
Second option {x | x > 7}
Step-by-step explanation:
We have the function

We know that the square root of a negative number has no solution in the real ones. Therefore the domain of this function is 
When applying the transformation:
we have a translation of the original function in 7 units to the right and 2 units to the top:

In the same way we must guarantee that 
Then
.
Therefore the domain of f(x) is {x | x > 7}

Answer:
(d)
Step-by-step explanation:
Bond's par value = $500
market value of the bond = 88.754% * 500
= 443.77
Commission rate charged by broker A = 3.1%
Commission of broker A =
*443.77
= $13.75687
Commission of broker B = $24
Difference between the commission of broker A and broker B = 24-13.756
= $10.24
Hence, (d) Broker A's commission will be $10.24 less then Broker B's.
Answer:
a) 0.997 is the probability that the breaking strength is at least 772 newtons.
b) 0.974 is the probability that this material has a breaking strength of at least 772 but not more than 820
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 800 newtons
Standard Deviation, σ = 10 newtons
We are given that the distribution of breaking strength is a bell shaped distribution that is a normal distribution.
Formula:
a) P( breaking strength of at least 772 newtons)
Calculation the value from standard normal z table, we have,

0.997 is the probability that the breaking strength is at least 772 newtons.
b) P( breaking strength of at least 772 but not more than 820)

0.974 is the probability that this material has a breaking strength of at least 772 but not more than 820.
