Answer: f( h(x) ) = 2x - 4</h3>
Work Shown:
f(x) = x - 7
f( h(x) ) = h(x) - 7
f( h(x) ) = 2x+3 - 7
f( h(x) ) = 2x - 4
Explanation:
In the second step, I replaced every x with h(x). In the next step, I replaced the h(x) on the right hand side with 2x+3. From there I combined like terms.
Answer:
19
Step-by-step explanation:
Y=2X
Looking at the line you can see that it is moving up from left to right, making it positive. So -2X and -12X are incorrect.
Next we can find the slope by putting rise over run. Chose a point on the line, I’ll use (2,4).
On this point we rise to 4 and run over to 2.
So for rise over run we have 4/2 which is 2.
So y=2x is correct.
Answer:
1245
Step-by-step explanation:
-Given the standard deviation is $9000 and the margin of error is $500.
-the minimum sample size at a 95% confidence level can be calculated using the formula:

Hence, the minimum sample size is 1245
*Since there's no data fromw which we are drawing our variables, we can manually input our parameters in excel and calculate as attached.
OK 33*76= 2508 if that is your question if its not tell me and i will see what i can do
