Answer:
C is greater
D is less
Step-by-step explanation:
Answer:
ME = z*s /√n
Step-by-step explanation:
The margin of error is obtained as the product of the critical value of the distribution at a certain α-level and the standard error :
The critical value = Z*
The standard error = standard deviation / √sample size
Standard deviation = s
Sample size = n
Margin of Error = z * s/√n
Answer:
200
Step-by-step explanation:
200 - 35% = 130
130 + 70 = 200
The way I picture this thing, it's made of three rectangles
that are joined together.
-- One rectangle is 3 x 6 meters.
-- One rectangle is 3 x 8 meters.
-- One rectangle is 3 x 10 meters.
-- Their 3-meter edges are all taped together to make a 'tube'.
-- It's 3 meters long, and it has 3 sides.
-- When you look at the ends of the tube, they're both
right triangles with sides of 6, 8, and 10 meters.
-- The area of each side = 1/2 (base x height)
= 1/2(6m x 8m) = 24 square meters.
2 ends = 48 square meters.
-- The lateral surface area is the area of the three rectangles
that make the 'tube'.
-- Area of the 6 x 3 rectangle = 18 square meters
-- Area of the 8 x 3 rectangle = 24 square meters
-- Area of the 10 x 3 rectangle = 30 square meters
-- Total lateral area = (18 + 24 + 30) = 72 square meters.
-- When you add the ends to it, you get
(72 + 48) = 120 square meters
for the total area.
Answer:
-7/3
Step-by-step explanation:
Use the equation y1-y=x1-x. In this case, I used the points (2,5) and (5,-2). Plug this into the equation to get -2-5/5-2. Simplify this to get -7/3. This means the slope is equal to -7/3.
