<span>At least 75% of the data will fall within 2 standard deviations of the mean.
This is tricky problem. Usually when you're dealing with standard deviation, you have a bell curve, or something close to a bell curve and for such a data distribution, there will be approximately 95% of the data within 2 standard deviations of the mean. But if you don't know that you have a bell curve, you have to fall back to Chebyshev’s Theorem, which states that at least 75% of the data points will fall within 2 standard deviations of the mean for any set of numbers.</span>
Answer: the answer is B
Step-by-step explanation:
i just did it
9x - 2y = 11 ... (i)
5x - 2y = 15 ... (ii)
Subtracting equation (ii) from (i) we get;
4x + 0 = -4
4x=-4 , x = -1
Replacing x = -1 in equation (i) we get;
9(-1) - 2y = 11
-9 - 2y = 11
-2y = 20
y = 20 ÷ -2 = -10
The solution to the system of equations is (-1,-10).
Answer:
Step-by-step explanation:
To owe money means you don't have any and borrowed some, or in other words are in debt. Only three of them are in debt, so Simpson doesn't owe anything.
For who owes more, let's start simple. If someone brrowed a dollar from a friend, they are in debt for a dollar. if they borrowed two dollars they suddenly owe more, two dollars instead of one. So Whatever amount of debt is higher tells the highest amoutn owed. Now, what is the highest amount any of the three remaining owe? well, 143 < 178 < 203, so 203 is the highest so Cole owes the most.
we have that
A square on a coordinate plane is translated 
units down and 
unit to the right
so
the rule of the translation is
therefore
<u>the answer is the option A</u>
T1, –9(x, y)
