Step-by-step explanation:
A binomial experiment is an experiment that has a fixed number of independent trials with only have two possible outcomes. This outcome could either be a yes or No.
example is when a coin is toss one can set it as either I will get a head or a tail.
The experiment is binomial because it has a fixed number of trial which is 3 calculator that has been picked,
It has two outcome which is either good or bad calculator and the each trial is independent of each other.

Answer:
(x-h)^2 + (y-k)^2 = r^2
Step-by-step explanation:
Here, we want to write the standard equation of the circle
We have this as;
(x-h)^2 + (y-k)^2 = r^2
The above equation is the standard equation for the circle
Answer:
B) 279.24
Step-by-step explanation:
line them up the multiple then move the decimal
2x^2+2x-4=2(2x^2+2x-4)/2=[2(2x^2)+2(2x)-2(4)]/2=[2^2x^2+2(2x)-8]/2
2x^2+2x-4=[(2x)^2+2(2x)-8]/2=(2x+4)(2x-2)/2=2(2x/2+4/2)2(2x/2-2/2)/2
2x^2+2x-4=2(x+2)(x-1)
Answer: Option B. 2(x+2)(x-1)
