The point estimate would be 2.25%.
Confidence intervals are centered around a point estimate; that is, the point estimate is in the very middle of the confidence interval. We can find the point estimate by averaging both ends of the confidence interval together:
(1.1+3.4)/2 = 2.25.
Answer:
6
Step-by-step explanation:
This is a right triangle, and so the Pythagorean Theorem applies. The legs of this triangle are 3√3 and 3; squaring these gives us 9(3) = 27 and 9. Then, this Theorem gives us the length of the hypotenuse as
h^2 = 27 + 9, or h^2 = 36, so that h, the length of the hypotenuse, must be 6.
Answer:
D) -5/3
Step-by-step explanation:
(Points on the graph): (6, 10) and (12, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-10)/(12-6)
m=(-10)/6
m = -5/3
Answer:
y=-1.5x-2
Step-by-step explanation:
18y=12x-72
3y=2x-12
y=2/3x-4
Slope=-1.5
7=-6(-1.5)+b
7=9-2
Answer:
$2,860
Step-by-step explanation:
2,500 * 3.8% = 90 in interest a year
so
90 * 4 = 360 in interest
add that to what she put in
2,860
