Answer:
volume of cube share box = 67.92 inch²
Step-by-step explanation:
given data
soccer ball volume = 85.3π cubic inches
solution
we know that ball will fit inside the box when box length will be equal to diameter of ball
and here soccer ball volume will be express as
soccer ball volume = 
.................1
85.3π =
solve it we get
r³ = 69.9765
r = 4.12 inch
so diameter = 2 × 4.12 = 8.24 inch
diameter = length of box side
volume of cube share box = a²
volume of cube share box = 8.24²
volume of cube share box = 67.92 inch²
He wrote identity instead of commutative in step 4
The small plane has the following parameters
Distance = 1200 miles
Speed = 300miles/hour
time = ?
If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours
Considering the distance of the small plane after 6 hours, we have
So the total distance = 1800 miles
Hence the speed of the Boeing 747 will be
The average speed of the Boeing 747 is 900 miles/ hour
Standard Deviation, σ: 1.5
Count, N: 10
Sum, Σx: 15
Mean, μ: 1.5
Variance, σ2: 2.25
Steps
σ2 =
Σ(xi - μ)2
N
=
(0 - 1.5)2 + ... + (5 - 1.5)2
10
=
22.5
10
= 2.25
σ = √2.25
= 1.5
X/5-4
The quotient of a number x and 5 is x/5.
Four less means you will subtract 4 from it.
