Okay, so it basically means you're subtracting.
I'm going to give some examples of what the answer could be.

1. 5 - 5 = 0
2. 5 - 4 = 1
3. 5 - 3 = 2
4. 5 - 2 = 3
5. 5 - 1 = 4
6. 5 - 0 = 5

Or of course if you feel you would like to switch the order of the problems, go ahead and try that, but no matter what happens, make sure the addition version always equal 5, so just be careful :)

mylen [45]

Answer:

a) 2.0702

b) 2.07

Step-by-step explanation:

Given:

Sample, n = 840

standard deviation, σ = 60

a) The standard deviation of the sampling distribution, will be:

= \frac{\sigma}{\sqrt{n}}

= \frac{60}{\sqrt{840}}

= 2.0702

Standard deviation of the sampling distribution is 2.0702

b) According to the 68 part of the 68-95-99.7 rule, 68% of all values of x fall within 1 standard deviation on either side of the unknown mean μ.

Therefore, missing number will be:

1 * [\frac{\sigma}{\sqrt{n}}]

= 1 * 2.0702

= 2.0702 ≈ 2.07

Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

81 {x}^{2}  - 324 {y}^{2}  \\  \\  =  {(9x)}^{2}  -  {(18y)}^{2}  \\  \\  = (9x + 18y)(9x - 18y) \\  \\  = 9(x + 2y) \times 9(x - 2y) \\  \\  = 81(x + 2y)(x - 2y)
