Answer:
2/3.
Step-by-step explanation:
Ok, so at first, the probability of the teacher picking a girl is 7/9. And then when she takes one girl, it is less, so the probability is 6/8. Then if she picks 2 more girls, then the probability of that would be 4/6, or 2/3.
He arrived with 32 dollars. This is because 1/4 of 32 is 8 and 1/2 of 32 is 16. 16+8=24
Well, 8000 (p) * 0.6 (r) = 4800, and if you multiply that by 1 (t) it's still 4800. So the value of I is 4800.
Answer:
D
Step-by-step explanation:
Answer:
Let's talk through this a one step at a time.
*Since f(x) is concave-up with its vertex on the x-axis, we know f(x) ≥ 0.
*We also know that when we shift a function's domain by a positive number, we shift the function left and when we shift a function's domain by a negative number, we shift the function right. So f(x-5) is f(x) shifted to the right by 5.
*At this point, f(x-5) has its vertex at (5,0).
*When we negate f(x-5), the parabola becomes concave down yet the vertex remains at (5,0). Now we're at -f(x-5). At this point we have -f(x-5)≤0 with a range (-∞,0]
*If we add 2 to create g(x)=2-f(x-5), then we have a concave down parabola with its vertex shifted up by 2, at (5,2). So, g(x) is concave down with its vertex at (5,2). Hence
