Note that 7 represents each of the different 7 regions in the spinner. 

1 would represent the red region, as there is one red region.

4 would represent the 4 green regions. Thus, 2 represents the 2 blue regions.



Note that as the spinner spins, no matter which region is colored with which color, the probability of hitting a blue region is \displaystyle{  \frac{2}{7}, as out of 7 regions we can hit, 2 are blue.

(Naturally enough, the greater the number of regions of a certain color, the greater the probability of hitting a region of that color.)


7 is the number of the elements in the sample space.

2 is the number of the elements in the event: "hitting blue".

This probability, as mentioned earlier, is matched by the outcome "hitting blue."

A cylindrical jar's lid has a radius of 4 inches. If the volume is 351.68 in , approximately what is the height of the jar?
balu736 [363]

Answer:

7 inches

Step-by-step explanation:

The volume of a cylinder is calculated using

V = \pi {r}^{2}h

where r =4 inches is the radius and V=351.68 is the volume.

To find the height of the jar, we substitute these values and solve for h.

351.68 = 3.14 \times  {4}^{2}  \times h

351.68 = 50.24h

Divide both sides by 50.24 to get:

h =  \frac{351.68}{50.24}

h=7 inches

Therefore the height of the jar is 7 inches
