The chance that any given bulb is on is equal to 1/2.  The chance that all twenty bulbs are on at the same time is (\frac{1}{2}) ^{20} = \frac{1^{20}}{2^{20}} = \frac{1}{1048576}

Write a proportion for 56% of a number is 244
Misha Larkins [42]
\frac{56}{100} =  \frac{244}{x} So, You cross multiply and get 56x=244(100). Simplify and you get 56x=24400. Divide each side by 56 and you get 435.71. 56% of about 435.71 is 244.

Round off 787592799 to the nearest 10​
timama [110]

Answer:

787592800

Step-by-step explanation:

Hi there,

If you round this answer to the nearest tens place, it would be 787592800. Since the 799 is closer to 800 rather than 790, it would round up and change the last three digits of the number instead of the usual two digits.

Hope this answer helps. Cheers.
