Step-by-step explanation:
P(heads) = ½, and P(tails) = ½
a) P(5 heads) = (½)⁵ = ¹/₃₂
b) P(5 tails) = (½)⁵ = ¹/₃₂
c) P(at least 1 head) = 1 − P(all tails) = ³¹/₃₂
Answer:
x=-12
Step-by-step explanation:
3x+5=2x-7
3x=2x-12
x=-12
Total yards if fabric /fabric needed to make an elf costume
therefore 16 1/5 ÷ 5 2/5
=3
so Barney can make 3 costumes out of 16 1/5 yards of fabric
Answer: C
Step-by-step explanation:because he will need to write an inequity to represent the total number of hours he can work each week . SO HE can see if he is making more then 120$ per week . No problem thanks me later
Answer:
All real solutions
Step-by-step explanation:
- The given graph is a maximum quadratic function.
- The solution to the graph is where the graph intersects the x-axis.
- We can see from the graph that, the function intersected the x-axis at two different points, hence its discriminant is greater than zero.
- Hence the solution of g(x) are two distinct real solutions.
- The solutions are not whole numbers because the x-intercepts are not exact.
- The solutions are also not all points that lie on g(x)
- The first choice is correct.
