Answer:
x=15
Step-by-step explanation:
so we are given one angle 90, although x is used in both so you can add them. We know that the sum of angle measures in a triangle is 180 so the equation is: 90+6x=180
subtract 90 from both sides: 6x=90
divide by 6: x=90/6
simplify: x=15
The answer is 10 or 11 .because if yu cancel out the 11 and 11 then cancel out 3 and 2 in between 9 and 12 is 10 and 11 so it’s either 10 or 11
30 punches each round...
i think :)
just divide the punches by the rounds hope this helps
There are 21 black socks and 9 white socks. Theoretically, the probability of picking a black sock is 21/(21+9) = 21/30 = 0.70 = 70%
Assuming we select any given sock, and then put it back (or replace it with an identical copy), then we should expect about 0.70*10 = 7 black socks out of the 10 we pick from the drawer. If no replacement is made, then the expected sock count will likely be different.
The dot plot shows the data set is
{5, 5, 6, 6, 7, 7, 7, 8, 8, 8}
The middle-most value is between the first two '7's, so the median is (7+7)/2 = 14/2 = 7. This can be thought of as the average expected number of black socks to get based on this simulation. So that's why I consider it a fair number generator because it matches fairly closely with the theoretical expected number of black socks we should get. Again, this is all based on us replacing each sock after a selection is made.
