Find the median of following data round to the nearest hundredth. <br> 12.5, 13.24, 7.89,22.45
NARA [144]
The "median" of a set is just the middle value for an odd number of ordered elements or the average of the middle two values for an even number of ordered elements.  In this case you are four elements so it would be the average of the second and third terms...

median=(12.5+13.24)/2

median=12.87  (exactly, no rounding needed)

Kipish [7]

Answer:

7 bags

Step-by-step explanation:

We solve using Greatest Common Factor Method

We have:

14 raspberry scones and 21 strawberry scones

We find the factors of 14 and 21

The factors of 14 are: 1, 2, 7, 14

The factors of 21 are: 1, 3, 7, 21

Then the greatest common factor is 7.

Therefore, the greatest number of bags Bryson can fill is 7 bags

Find the volume of each cylinder. Use 3.14 for pi. Round your answer to the nearest tenth
otez555 [7]

Answer:

V ≈471.24 mm^3

Step-by-step explanation:

The formula for cylinder volume is πr^2 x h, so ((π x 25) x h). That's just 25π x 6. That is about 471.238898, which rounded is almost 471.24. Or, in terms of π, you could leave your answer as 150π mm^3

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone i
kondaur [170]
Given:
Volume of the cone = π r² h/3

radius of the cone is half the radius of the cylinder ⇒ r/2
height of the cone is equal to the radius of the cylinder. ⇒ r

V = 3.14 * (r/2)² * r/3
V = 3.14 * r²/4 * r/3
V = 3.14r³ / 12
