Answer:
Step-by-step explanation:
(2-2)/(5+1)= 0/6= 0
y - 2 = 0(x + 1)
y - 2 = 0
y = 2
Answer:
B. 34%.
Step-by-step explanation:
94 - 78 = 16 which is 2 times the standard deviation from the mean.
For a normal distribution this is 34% of the total students.

Answer:
38
Step-by-step explanation:
From the analysis of the previous sales.
25% of Software sold were for Home Productivity.
Therefore, if the manager plans to order 150 software packages, 25% of them should be for home productivity.
Total Number of Software to be ordered=150
Number of home productivity software
=25% of 150 =0.25 X 150=37.5
Since the manager cannot order a decimal number, we round it up to 38.
Therefore, the manager should order 38 home productivity software.
The best approach to this is to use the formular
Standard error = standard deviation / sqrt( sample size)
standard deviation = 0.75 hours
sample size = 35
Hence, Standard error = 0.75 /sqrt(35) = 0.126 = 0.13
If you would like to solve (n^3 - n^4) - (3n^3 - 7n^4), you can do this using the following steps:
(n^3 - n^4) - (3n^3 - 7n^4) = <span>n^3 - n^4 - 3n^3 + 7n^4 = n^3 - 3n^3 - n^4 + 7n^4 = -2n^3 + 6n^4
</span>
The correct result would be <span>-2n^3 + 6n^4.</span>
