Answer:

r=5

Step-by-step explanation:

Circumference of a circle =

Since w are given that the circumference of circle is 31.4 cm

So,

[tex5= r[/tex]

So, radius of given circle is 5 cm

Area of circle =

                      =

                      =

Thus the area of circle is 78.5 sq.cm.

Hence the radius of given circle is 5 cm and the area of the circle is 78.5 sq.cm.

You decided to throw a fair die four times.
Finger [1]

Answer:

If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.

the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).

68.64 divided by 2.4 SHOW WORK PLEASE
34kurt

Answer:28.6

I started by seeing how many 2.4 can go into 68.64. I found that it is pretty easy to find that if you multiply the 2.4 by ten you get 24 so we do that twice and have 48. We then subtract 48 from the 68.64 which leaves us with 20.64. If we multiply 2.4 by 5 we get 12 so once again subtract 12 from that 20.64 and now we are left with 8.64. So now we need to figure out how many more 2.4 are left well it is more than three because three gives us 7.2 so let’s subtract that from it now we are left with 1.44. Now we need to find out what times 2.4 gives us 1.44. Well it would be .6. So now if we add up everything we get the answer of 28.6. Sorry if this very complicated
