Principle: divide the correct possibilities by the total nr. of possibilities to find the probability.
6. P(green) = 5 / (7+5+6) = 5/18
7. P(red) = 6 / 18 = 1/3
8. P(not green) = P(red | blue) = (6+7)/18 = 13/18
9. P(HH) = 5/25 = 1/5
10. P(HT) = 16/25
11. P(NOT TT) = P(HH | HT) = (5+16)/25 = 21/25
12. P(HH | TT) = (5+4)/25 = 9/25
13. P(5) = 1/6. P(H) = 1/2. P(5 & H) = 1/6*1/2 = 1/12. If you draw all the possibilities, you'll find there are 12. One of them is 5 & Heads.

Answer:
1620°
Step-by-step explanation:
The formula for finding that measure is ...
sum of interior angles of n-sided convex polygon = 180°×(n -2)
For n=11, this is
sum = 180°×9 = 1620°
_____
Another way to get there is to remember that the sum of <em>exterior</em> angles is always 360° for a convex polygon. Then the total (interior + exterior) of the angles of an n-sided polygon is 180°×n. Subtracting the sum of exterior angles gives the total of interior angles: 180°×n -360° = 180°×(n -2).
Answer:
x = 3.5 + 0.5y
Step-by-step explanation:
Simplifying
2x + -1y = 7
Solving
2x + -1y = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y = 7 + y
Combine like terms: -1y + y = 0
2x + 0 = 7 + y
2x = 7 + y
Divide each side by '2'.
x = 3.5 + 0.5y
Simplifying
x = 3.5 + 0.5y
Answer:
75.03
Step-by-step explanation:
14×11×sin(77)
= 75.02649499..
≈ 75.03 (rounded to nearest hundredth)
