Answer:
A) 4
B) Mode is 5
C) 10.5
Step-by-step explanation:
A) 62+x/12
(62 + x) ÷ 12 = 5.5 ×12
62 + x = 66
×= 66-62
×=4
B) mode is the highest occuring no which is 5
C) mean has been given as 5.5; mean plus mode= 10.5
a) 4
b) 5
c) 9
a) let the 12th number b x
Mean = sum/n
5.5 = (5+6+5+3+4+5+7+6+9+7+5+x)/12
5.5×12 = 62+x
66 = 62+x
x = 4
b) set is: 3,4,4,5,5,5,5,6,6,7,7,9
Mode is 5 (most frequent)
c) mode+mean = 5+4 = 9
The chosen topic is not meant for use with this type of problem. Try the examples below.
y = x+4
y = 2x-5
y = x-1
In order to answer, I would first need to know Jana's speed, not that she biked at a constant rate.
r=-45
r/5=-9
x 5 x5

Using the formula for area of a circle:
Area = pi x radius^2
Replace area with the given value:
39.62 = pi x radius^2
Divide both sides by pi
Radius^2 = 39.62/pi
Radius^2 = 12.62
Solve for radius by taking the square root of both sides
Radius = sqrt(12.62)
Radius = 3.55 cm
unequal Triangle
If two sides of a triangle are unequal, The angle opposite to the greater side is greater than the angle opposite to less.That is,
In a triangle ΔABC,
if AC > AB then ∠B > ∠C
