it's D becuase when you round all of them 124.2 is the only one thats different.
124.5 Rounded is, 125
125.3 Rounded is 125
124.9 Rounded is 125
124.2 Rounded is 124
Hope this helps. (i'm doing the same test lol)
For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is
Answer: We are required to find the value of z corresponding to probability 0.8340.
i.e., 
We can find the value of z using the standard normal table.
Using the standard normal table, we have:

Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340
Attached here standard normal table for your reference.
Answer:
y = 5x + 4
Step-by-step explanation:
Starting with 5x - y = -4
Subtract 5x from both sides to get -y = -5x - 4
Multiply the entire equation by -1 to make the y positive
You get y = 5x + 4
Yes, it is! The unfactored version of that expression would be 2x+10.
