<h3>Problem Solution</h3>
Assuming the spool is a cylinder and the circumference we're winding around is that of a circle with the given area, we can write the relation between circumference and area as
... C = 2√(πA)
10 times the circumference is then
... 10C = 20√(π·20 cm²) = 40√(5π) cm ≈ 159 cm
<h3>Formula Derivation</h3>
The usual formulas for circumference and area are
... C = 2πr
... A = πr²
If we multiply the area formula by π and take the square root, we get
... πA = (πr)²
... √(πA) = πr
Multiplying this by 2 gives circumference.
... C = 2√(πA) = 2πr
Answer:
The criterion for binomial experiment are:
a. The probability of success on each trial is constant
c. The experiment must include a fixed number of trials repeated under identical conditions
d. The trials are independent.
f. The trials are mutually exclusive
e. The trials have exactly two possible outcomes.
Step-by-step explanation:
The conditions for binomial experiment are that the probability of success remains the same in each trail and the experiment has two outcome success or failure. The trails are mutually exclusive means that the outcome may be success or failure. The trails are repeated fix number of times independently i.e. a trail don't effect the outcome of the other trial.
3t+3/5=6
3t = 6-3/5
3t = 27/5
t=9/5
Work shown above! Hope ya understand!
