Answer:
it should take her 45 minutes to run 9 laps
Step-by-step explanation:
40/8 = 5
9*5 = 45
Answer:
a) It can be used because np and n(1-p) are both greater than 5.
Step-by-step explanation:
Binomial distribution and approximation to the normal:
The binomial distribution has two parameters:
n, which is the number of trials.
p, which is the probability of a success on a single trial.
If np and n(1-p) are both greater than 5, the normal approximation to the binomial can appropriately be used.
In this question:
So, lets verify the conditions:
np = 201*0.45 = 90.45 > 5
n(1-p) = 201*(1-0.45) = 201*0.55 = 110.55 > 5
Since both np and n(1-p) are greater than 5, the approximation can be used.
Answer:
The Answer is: Perimeter = 39.12
Step-by-step explanation:
Given: area is 56.96 m^2
Given: length is 16m.
Find Width.
Equation:
Length x Width = Area
Solve for Width, w.
16 x w = 56.96
w = 56.96/16 = 3.56.
Perimeter all the sides added together:
P= 2l + 2w
= 2(16) + 2(3.56)
= 32 + 7.12
= 39.12 m, perimeter

Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
3600π = πD
D = 3600 ← Divide by π on both sides
------------------------------------------------------
Answer: Diameter = 3600 unit
