An article presents a new method for timing traffic signals in heavily traveled intersections. the effectiveness of the new method was evaluated in a simulation study. in 50 simulations, the mean improvement in traffic flow in a particular intersection was 655.3 vehicles per hour, with a standard deviation of 311.7 vehicles per hour. with what level of confidence can this statement be made?

Cylinders have two circular bases

Cones have one circular base

The lateral area of a cylinder is related to circumference of the circular bases.

Step-by-step explanation:

In Determining the statements that characterize cylinders and cones. All that apply in this context are :

1) Cylinders have two circular bases

2) Cones have one circular base

3) The lateral area of a cylinder is related to circumference of the circular bases.

Furthermore, in a general context, A cylinder has traditionally been or comprises of a three-dimensional solid, one of the most basic of curvilinear geometric shapes or curves. It is the idealized version of a solid physical tin can which processed lids on top and bottom. While a cone is a three-dimensional geometric shape or a set of line segment that taper smoothly from a flat base (though not necessarily, but mostly circular) to a point called the vertex.
