Answer:
5
Step-by-step explanation:
The probability of tails is 1/2, so the expected value is (1/2) (10) = 5.
Answer:
i'm pretty sure its B but it would be helpful if i could see a graph
Step-by-step explanation:
Yo sup??
by Pythagoras theorem we can say that
DE²=3²+2²
=9+4
DE=√13
=3.60 units
angle D=tan-1(2/3)
=33.7
angle E=tan-1(3/2)
=56.3
Hope this helps
The ordered pair (- 3, 1 ) is a solution to the second equation because it makes the second equation true
To test , substitute the coordinates of (- 3, 1) into the equations and if both sides are true then it is a solution to the equation.
x - 4y = - 3 - 4 = - 7 ≠ 6 ← not true
(3 × - 3) + 1 = - 9 + 1 = - 8 ← true
Thus (- 3, 1 ) is a solution to the second equation
25+50
=75
All you do is multiply 5 and 10 by 5 and add them up
