Answer:
x = - 90
Step-by-step explanation:
Given

Step-by-step explanation:
<span>Quartiles are generally more reliable for judging outliers than mean and standard deviations for 2 reasons. The mean is simply the average of all of the numbers, meaning that an outlier can easily be obscured by the masses. Standard deviation is a better method, however only going over by one standard deviation in either direction would also mask an outlier. A strong outlier however will pull a quartile farther in that direction than would normally be expected.</span>
Answer:
y =20
Step-by-step explanation:
5(y+4)=6y
Distribute
5y +20 = 6y
Subtract 5y from each side
5y-5y+20=6y-5y
20 =y
the standard form of a quadratic is simply the equation with all variables and constant on the left-hand-side.
y = 3x² <--- general form
-3x² + y = 0 <--- standard form.
