Answer:
20, and 26 are the middle - 23 is the average. Your answer is 23.

Answer : Y=-15/7
Explanation:
If you want 3/4 in 64's, multiply the numerator (3) by 16, as 4 x 16 = 64.
<span>3 x 16 </span>
<span>--------- </span>
<span>4 x 16 </span>
<span>= 48/64</span>
So, 9 out of 10 students prefer class, so, obviously, it would not be 100. It would be 150. So in conclusion, 50 students prefer lunch over math class, whilst 150 other students prefer math class over lunch.
After the 3rd pick we have: 4 white, 3 red and 8 black marbles.
The probability that the 4th marble is black is:
P ( Black ) = 8 / 15 = 0.5333
After the 4th pick we have: 4 white, 3 red and 7 black marbles.
P ( Red or Black ) = 10 / 14 = 5 / 7 = 0.7143
