number of cards = 100

number less than 14 = {2,3,...,13} = 12

number perfect square = {4, 9, 16, 25, 36, 49, 64, 81, 100} = 9

so

a) probability = 12/100 = 3/25

b) probability = 9/100

Need the answer for this thanks. I got C but that is incorrect​. Please show work thanks! ​
natulia [17]

Answer:

Step-by-step explanation:

a: Wrong. The first thing that you have to notice is that the sum goes to infinity. If you want k=4 to be the last condition, then take out the 3 dots.

b: That's the answer.

c: wrong. You get a real mess when you let set k = 0. Try it on your calculator.

1 ÷ 0 = Watch carefully as your calculator mentally melts down.

d: wrong. It's just not right. The highest power is k^2. There is no way to get k^3

in Math class we are Learning about Pi which equals 3.14 how do you find the diameter and radius i dont understand it can you gu
kirill [66]
If you're finding diameter or radius based on circumference, use the formula C = πd. You would divide the circumference by pi to get the diameter, then divide the diameter by 2 to get the radius.

If you're finding diameter or radius based on area, use the formula A = πr^2. You would divide the area by pi, then find the square root of that value which is the radius. Just multiply the radius by 2 to find diameter.
