The best estimate product for 289 and 7 (after rounding it to the nearest ten) is 2900, because:
290 * 10 = 2900
Answer:
factors of 7: 1, 7
factors of 10: 2, 5
1*-2 = -2
7*-5 = -35
...
-35 + -2 = -37

Answer:
First step is to subtract 986 from both sides.
Step-by-step explanation:
I would subtract 986 from both sides because then it will balance out the equation; variable on one side and the number on one side. With this it will be easier to solve for n.
Answer:
See below.
Step-by-step explanation:
The standard deviation = √ (∑(x - 10)^2 / 8 ) must be approximately = 1 if we take the mean to be 10.
This requires ∑ (x - 10)^2 to be approximately equal to 8.
The following data set would fit the bill:
8.6 9 9 10 10 11 11 11.5.
The values of (x - 10)^2 could be 1.96, 1, 1, 0,0, 1, 1, 2.25 = 8.21
This would give a mean of about 10 and standard deviation of about 1.
