1. write three different statements that describe the variability in Leah’s reaction times from the value bar graph.

2. Below is a value bar graph showing data about Ella‘s reaction times. Compare Ella‘s reaction times to Leah’s reaction times.

a. Determine statistics for each student: means, medians, and ranges

b. Is one student quicker than the other student? Explain your reasoning.

c. Is one student more consistent than the other student? Explain

Iam at home. /: i am playing video games. translate the following statement into symbolic form.

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)

The volume of a rectangular prism is found by multiplying the length, width, and height of the prism. a rectangular prism has a width of 5x^2units, a length of 7x^3 units and a height of 2x^4 units. which is the volume of the prism in terms of x?
