Step-by-step explanation:
You can't expect to get exactly 2500 out of 5000 tosses more than a few times . You will come pretty close, but that's only good in horseshoes.
Of course I'm answering this on the basis of a computer language and not actually performinig this a million tmes, each part of a million consisting of 5000 tosses.
Simulations and not completely unbiased, but based on experience, 5000 is a very small number and getting 2500 more than a couple of times is unlikely
Answer:
No it doesn't.
Step-by-step explanation:
In order for y to represent a function of x, no two x values can have the same y values. Basically x causes y and if y is the same under two different x values then the table isn't true. You can also use the vertical line test to ensure you are correct. I may not be correct but I believe I am
Answer:
i) vertical
ii) corresponding
iii) alt. interior
iv) corresponding
v)alt. exterior
vi) corresponding
Step-by-step explanation:
corresponding angles make an F when traced, alternate interior angles make a Z when traced, and same side interior angles make a C when traced. (just a tip!)
Answer:11
Step-by-step explanation:
Boys : girls=7:1
Sum of ratio=7+1=8
Let them number of girls be y
Then they number of boys=y+66
Total number of pupils=y+y+66
Total number of pupils=2y+66
Number of girls=(girls ratio)/(sum of ratio) x (total number of pupils)
y=1/8 x (2y+66)
Cross multiply
y x 8=2y + 66
8y=2y + 66
Collect like terms
8y-2y=66
6y=66
Divide both sides by 6
6y/6=66/6
y=11
The number of girls is 11
