Since there is either heads or tails, meaning only two options you have a 50% chance of getting heads
Answer:
just add up all the number in your calulator
Step-by-step explanation:
From the system of equations, we have 3 unknowns and 3 equations. Therefore, it can be solved.
<span>3x - 2y + 2z = 30 (1)
</span><span>-x + 3y - 4z = -33 (2)
</span><span>2x - 4y + 3z = 42 (3)
We can write equation 2 x as a function of y and z and substitute the new equation to the other equations.
</span>x =3y - 4z + 33 (2)
3 (3y - 4z + 3)<span> - 2y + 2z = 30 (1)
</span>2 (3y - 4z + <span>3)</span> - 4y + 3z = 42 (3)
We simplify and solve the equations and we get values,
x = 4
y = -7
z = 2
<span>180-90-50=40 degrees</span>
Answer:
n= 100
Step-by-step explanation:
Product is the answer when two numbers are multiplied together. So, n×-6=600.
100×-6=-600
