C) 23.
The answer is D because if you use the formula perfectly
Answer:
The circumference of a circle is pi times diameter, so half-way around the pond is (1/2)pi times diameter.
The difference between walking around the pond and walking across the bridge is: 1.57d - d = 0.57d
Plug in diameter of 0.25
0.25*0.57 = 0.14 miles

Answer: Hello!
Here you have 53 integrated circuits, each with a probability of 0.02 of being defective.
If only one of them is defective, then the electronic product doesnt work.
Then we need the calculate the probability in wich all the 53 circuits arent defective.
the probability for each one to not be defective is 1 - 0.02 = 0.98
And if i want to see the probability for all of them to work fine, then i need to do the product of all the probabilities, this is multiply 0.98 53 times, or:

rounding to the four decimal place, we have: 0.3428
Wich is a kinda small probability for our product to work.
