A class tracked the hours each student played games per month. Answer the questions below.

adelina 88 [10]

Answer:

a) 4.33 (three repeating)

b) 3.5

c) 3

d) 0.44

Step-by-step explanation: Mean is all the numbers added up and divided by the amount of items. All the items added together are 78. We have 18 items 78/18 = 4.3 (three repeating). Median is just the middle value. This is between 3 and 4 so 3.5. Mode is the one that shows the most. This is 3. 8 students play games for more than 4 hours. 8/18 = 0.44

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of a right cylinder that

Anna71 [15]

Answer:

The volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.

Step-by-step explanation:

Given that,

The volume of a right circular cone is 300 cubic inches

We need to find the volume of a right cylinder that has the same base and height as the cone.

Volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2h$

And volume of a cylinder is given by :

$V'=\pi r'^2 h'$

If the base and height of cone and cylinder are same, r=r' and h=h'

$\dfrac{V}{V'}=\dfrac{1/3\pi r^2 h}{\pi r'^2h'}\\\\=\dfrac{1/3\pi r^2 h}{\pi r^2h}\\\\\dfrac{V}{V'}=\dfrac{1}{3}\\\\V'=3V$

So, the volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.

at a baseball game, a vender sold a combined total of 221 sodas and hot dogs. the number of hot dogs sold was 59 less than the n

marishachu [46]

Let h be hot dogs and s be sodas

h+s=221
h=s-59
s=s

s+s-59=221
2s-59=-221
2s=280
s=140
h=140-59=81
140+81=221

Answer: there were 81 hotdogs and 140 sodas sold
