Answer:
x = 5
Step-by-step explanation:
The figure shows that angles EAF and FAL are congruent, so we can equate their measures and solve for x.
4x + 10 = 3x + 15
Subtract 3x from both sides. Subtract 10 from both sides.
x = 5
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
Answer:
They have no minimum y -value
Answer:
-3
Step-by-step explanation:
Answer:
This equation has no real roots
Step-by-step explanation:
We want to solve
We group all terms on the left:
Divide through by -6
The discriminant is
This means the given equation has no real solution, since the discriminant is less than 0
