Determine the standard variation of the data below. (1, 2, 3, 4, 5)
Ne4ueva [31]
Calculate for the mean/ average of the given numbers:
 
                             μ = (1 + 2 + 3 + 4 + 5) / 5 = 3

Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
 
                             S  = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
                                S = 10

Divide this summation by the number of items and take the square root of the result to get the standard deviation.

                              SD = sqrt (10 / 5) = sqrt 2  
                                    SD = 1.41

Thus, the standard deviation of the given is equal to 1.41.

Steven conjectures that for |x|>5, it is true that x^3>125. Is his conjecture correct? Why or why not?
vredina [299]

Conjectures are conclusions formed from evidences. Steven's conjecture that: x^3 > 125 is true because: x > 5 or x > -5 for |x| > 5

Given that:

|x| > 5

Split the inequality as follows:

x > 5 or x > -5

Take the cube of both sides

x^3 > 5^3 or x^3 > -5^3

Evaluate all exponents

x^3 > 125 or x^3 > -125

Steven's conjecture that: x^3 > 125 is true because:

x > 5 or x > -5 for |x| > 5

Let p: The kitchen is clean. Let q: The bedroom is clean. Which statement is true if the kitchen is clean but the bedroom is not
Ivan

P = The kitchen is clean → TRUE

Q = The bedroom is clean → FALSE


1) If P is true, then Q is true. → False statement

2) Statement Q is true if and only if P is true. → False statement

3) Both p and q are true. → False statement

4) Statement P or Q is true. → True statement ⇒ Statement P is true.


The answer is: The statement "Statement P or Q is true" is true.


There you go! I really hope this helped, if there's anything just let me know! :)

Rachel bought 1500 shares of cash
Elina [12.6K]

I think this was ur question Rachel bought 1,500 shares of Cawh Consolidated Bank at a price of $24.85 each. As the price climbed, she sold off parts of her holdings. She sold off 250 shares at $28.32 apiece, she sold 800 of her shares at $33.60 apiece, and she sold off the remainder of her shares at $39.94 apiece. If Rachel's broker charges a commission of $65 per $1,000 of stock bought or sold, how much profit did Rachel make, to the nearest dollar?

I think the answer is 8,859? I don't know what the question was, but I think that's it. Hope this helps. c;
