I would but I can’t see the picture I don’t know why... what is the question please type it ,thank you
It's a table, not a graph. Either way everyone should statistically get either 7 heads and 8 tails or 8 heads and 7 tails if they flip it 15 times.
I need more context in order to answer this so please comment so I can help
Answer:
25 black keys
Step-by-step explanation:
Let the number of requires black keys = 'x'
White key : Black keys = 7 : 5
7 : 5 :: 35 : x
Product of extremes = product of means
7 *x = 35 * 5
x = 
x = 5 *5
x = 25
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).
