The probability is 4:20
It is correct because there are 20 students and there could be 4 guesses
Answer:
3.706 liters
Step-by-step explanation:
Hello
assuming that these measures correspond to the internal measures of the thermos,
we can calculate the volume as, the volume of a cylinder, which is given by

where r is the radius of the base, and h the height
also
Diameter=2r
r=Diameter/2
Step 1
let
h=8 in
base = diameter = 6 inch
r=diameter/2
r=6/2 inch,r=3 inch
Step 2
Put the values into the equation

Step 3
Now, the unit (cubic inches) is not an usual unit for measuring coffee, let´s convert cubic inches into liters by knowing
1 inch = 2.54 cm
1 litro = 1000 cubic centimeters

1 cubic inch = 16.3870 cubic centimeters

Step 4
Finally, convert cubic centimeters into liters
I can put 3.706 liters in the thermos
Have a good day
Answer:
R
Step-by-step explanation:
(10+×)^2
expand
(10+x)(10+x)
multiply
100+10x+10x+x^2
add
100+20x+x^2
rearrange
x^2+20x+100
if this is what you mean this is the answer if you want to know what x is just set ()=0 and solve
x+10=0
x=-10
but I believe you are asking for the equation hope that helps let me know :)
