Answer:
2/
For all values of x,
f(x)=2x-3
and
a) Find fg(x).
Simplify and give your answer in the form ax² + b
b) Find gf(x).
Simplify and give your answer in the form ax² + bx + c
g(x) = x² + 1
Step-by-step explanation:
The answer to your question is option A
Let n = total boxes (5)
Probability (p) = 1 out of 4 = 1/4 = 0.25
Probability she wins at most 1 out of 5 is p(x <=1) Which is also = p (x =0) + p(x=1)
Probability of not winning would be 0.75 ( 1-0.25)
No prizes in 5 boxes = 0.75^5
1 prize in 5 boxes = 5 x 0.25 x 0.75^4
Total probability = 0.75^5 + 5 x 0.25 x 0.75^4 = 0.63
3 types
There are three types of systems of linear equations in two variables, and three types of solutions. An independent system has exactly one solution pair (x,y) . The point where the two lines intersect is the only solution. An inconsistent system has no solution.
The answer is TRUE <3 hope this helps
