Answer:
Step-by-step explanation:
This is one of those formulas of algebra and geometry that you need to learn. If you know the radius and the height of a vertical cylinder, then its volume is equal to the (base area) times the (height), which, symbolically, are
V = (base area)(height)
Here,
V = πr²· h where πr² is the area of the base (which is a circle of radius r) and h is the height of the cylinder.
The point estimate is the mid-point of the interval:
The margin of error is the difference between the endpoints of the interval and the mid-point.
Answer: -2/3
3-(-1) over
-2-4
This equals 4/-6 which reduces to -2/3

Answer:
90% is close to 75
Step-by-step explanation:
90% of a number would be 3 times 30% of a number. As a result we can assume 90% of the number would be around 3(25) or 75
