Answer:
Step-by-step explanation:
we know that
<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
To calculate combinations, we will use the formula
where
n represents the total number of items
r represents the number of items being chosen at a time.
In this problem
substitute
simplify
No, the question is not a statistical question.
Answer: 
Step-by-step explanation:
The average speed of the car is 40 miles per hour:
The car drives for 45 minutes:
Since 1 hours has 60 minutes, we can convert the time from minutes to hours:
Knowing these values, we can use the following formula for calculate the distace "d":
Therefore, substituting values into the formula, we get:
Answer:
Given diameter: r = d / 2 , Given area: r = √[A / (4 * π)] , Given volume: r = ³√[3 * V / (4 * π)] , Given surface to volume ratio: r = 3 / (A/V) .
Step-by-step explanation:
So, do that!
