The probability of getting all heads is 1 / 2^6 = 1/64 as there is only 1 event where this happens in a possible 2^6 = 64 events. It is the same as the probability of getting all tails. The probability of getting at least 1 head is 1 - p(all tails) = 63/64.
Answer:
x=0 or x=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
(x+2)2=4
Step 1: Simplify both sides of the equation.
x2+4x+4=4
Step 2: Subtract 4 from both sides.
x2+4x+4−4=4−4
x2+4x=0
Step 3: Factor left side of equation.
x(x+4)=0
Step 4: Set factors equal to 0.
x=0 or x+4=0
x=0 or x=−4
Answer:
5 nights
Step-by-step explanation:
Solve the inequality:
90x + 90(0.1)x + 12x + 30 
600
Add like terms:
102x + 30 + 90(0.1)x 600
Isolate the variables:
102x + 90(0.1)x 570
102x + 9x 570
111x 570
x 5.13
So, the Lincolns can stay for 5 nights without exceeding $600
