Answer:
Square root of the variance of the "number of daily parking tickets"
Step-by-step explanation:
The Standard Deviation is a measure of how spread out numbers are.
Its symbol is σ (the Greek letter sigma)
The formula is easy: it is the square root of the Variance.
To solve this, you have to divide 50 by 10, which is from the original ratio. You should come up with 5, so then you multiply 5 times 7 to equal the 50 votes for candidate A, which would be 35. Add 50 to 35, and your answer is 85! :D please brainly!

Answer:
The simplified expression is:
= 4(x-5)(x-2)
Step-by-step explanation:
Given that:
=4(x-5)² + 12(x-5)
By simplifying we get
= 4(x^2 -10x + 25) + 12x - 60
= 4x^2 - 40x + 100 + 12x - 60
Adding like terms:
= 4x^2 -28x + 40
=4(x^2-7x+10)
=4(x^2-2x-5x+10)
=4(x(x-2)-5(x-2))
By taking common we get:
= 4(x-5)(x-2)
This is the simplified expression.
I hope it will help you!
Answer:
8x - 4y + 12
Step-by-step explanation:
-2(-4x + 2y - 6)
(-2)(-4x) + (-2)(2y) + (-2)(-6)
(2 * 4x) - (2 * 2y) + (2 * 6)
8x - 4y + 12
