Answer:
54779098.9847
Step-by-step explanation:
You add them together
Answer:
The Domain is where the line on your graph crosses the X axis.
The Range us where the line on your graph crosses the Y axis
And a arrow means it goes Into infinity
Step-by-step explanation:
Say you Have a line, it crosses the X axis at -3, your Domain would be -3!
Now say this line crosses the Y axis at -6, Your Range would be -6!
And now say if instead of the line ending at a dot after crossing -6 It has a arrow, that means you have infinity, Making your range instead of -6 it's be infinity! (If the arrow points up it's positive infinity, If the arrow points down it's negative infinity)
So for the first 2 numbers your answer would be [-3,-6] and in you have infinity itd be [-3, infinity) parenthesis isn't a error btw if you still don't get it I can just reply with a sheet I have on it
A. we use the z statistic to solve this problem
z = (x – u) / s
We calculate the value of the sample mean u and standard deviation
s:
u = $30 * 304 = $9120
s = $21 * 304 = $6384
z = (9,600 – 9120) / 6384
z = 0.075
From the normal tables using right tailed test,
P = 0.47
B. At worst 11% means P = 0.11, so the z value at this is
z = -1.23
-1.23 = (x – 9120) / 6384
x = 1267.68
