Answer:
With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
Step-by-step explanation:
The lower bound of the confidence interval is 29.9%.
So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.
Out of 6 million, that is:
0.299*6000000 = 1,794,000
With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
Answer:
the y coordinate is 5
Step-by-step explanation:
In the figure attached, the directed line segment is shown.
J is located at (-3, 1) and K is located at (-8, 11)
run: x2 -x1 = -8 - (-3) = -5
rise: y2 - y1 = 11 - 1 = 10
Taking J as reference, the coordinate of the point that divides the directed line segment from J to k into a ratio of 2:3 is:
c = 2/(2+3) = 0.4
(x1 + c*run, y1 + c*rise)
(-3 + 0.4*-5, 1+0.4*10)
(-5, 5)
Answer:
Step-by-step explanation:
2a + 6 / a² -9 = 2(a + 3) / (a² -3²)
= 2(a+3) / (a+3)(a-3) {a²-b² = (a+b)(a-b)
= 2 / (a-3)
