The expected number of heads seen in 12 flips is 8 heads seen
The partial circles in each corner mean that all 3 angles are identical, which means this is an equatorial triangle. In an equatorial triangle all three sides are the same.
We can set two of the equations to equal each other and solve for x:
3x -5 = 2x +20
Add 5 to each side:
3x = 2x +25
Subtract 2x from each side:
x = 25
Answer:
25%
Step-by-step explanation:
You have 60 total, 30 on the track team would be 50%, but there is only 15 on the track them, you cut the 50% in half again which gives 25%.
<span>To create a flexible street/block pattern that would accommodate a range of densities and residential and recreational uses, the Canadian planners adapted the street grid of Savannah to allow development of individual but continuous neighborhoods.</span><span>
The original </span>plan actually called for six squares, and as the city grew the grid<span> of wards and squares was extended so that 33 square.

Answer:
Option C.
Step-by-step explanation:
The given equations are


We need isolate one of the variables, such that it appears by itself on one side of the equation.
Isolating a variable in two equations is easiest when one of them has a coefficient 1.
In equation 1, coefficient of B is 1. So, we can easily isolate one of the variables.
The equation is

Subtract 3A from both sides.

Multiply both sides by -1.

Therefore, the correct option is C.
