Answer:
Approximately 3.1 hours.
Step-by-step explanation:
We have been given that Amy counted 60 numbers per minute and continued to count nonstop until she reached 11,000.
First of all, we will divide total numbers by number counted per minute to find minutes taken by Amy to count total numbers.
We know that 1 hour equals 60 minutes, so we will divide 183.33333 by 60 to convert time in hours as:
Therefore, it will take Amy approximately 3.1 hours to complete the counting.
Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.
P=
For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.
P(4)=1/6
Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:
1
23
45
6
Of the 6 possibilities, 3 are even numbers.
P(even)=3/6 or 1/2
there is a formula A = 2π r h + 2π r².
=> h = (A - 2π r²) / 2π r
=> h = ( 616 - 2π(7)^2) / 2π(7)
=> h = 7.0
The answer is D. Most students are young enough not to have much of a credit score or credit history...
That's basic trigonometry
Tangent 57 degrees = AC / 9
AC = Tangent 57 degrees * 9
AC = 1.5399 * 9
