Answer:
14110
Step-by-step explanation:
Let x = number of pages ;
μ = 12200 ; σ = 820
Zscore = (x - μ) / s
Zscore = (x - 12200) / 820
Zcritical at 99% confidence, for a 1 - tail test is 2.33
Hence, Z at 99% = 2.33
Put Zscore = 2.33
Zscore = (x - 12200) / 820
2.33 = (x - 12200) / 820
2.33 * 820 = x - 12200
1910.6 = x - 12200
1910.6 + 12200 = x
x = 14110.6
x = 14111
The number of pages the manufacturer should advertise is 14,110

Answer:
the last one
Step-by-step explanation:
when looking for the function we have to know that none of the x values can repeat
in the first one the x value -5 repeats twice so that cannot be the answer
in the second one the x value 2 repeats twice so that cant be the answer
in the third one the x value -7 repeats twice so that also cannot be the answer
in the last one each x value has a different y value or every input has a different output therefore this one is the right answer
hope this helps :D
Well the position function is:
h(t)=-16t^2+256
It will hit the ground when h(t)=0
-16t^2+256=0 factor out -16
-16(t^2-16)=0 factor difference of squares...
-16(t+4)(t-4)=0, since t>0
t=4 seconds
