The odds against Carl beating his friend in a round of golf are 7:5. Find the probability that carl will beat his friend.
Leya [2.2K]

Answer:

\frac{5}{12}

Step-by-step explanation:

In other words, carl's losing odds are 7 : 5, so his winning odds will be 5 : 7

So if they play (7+5=12) 12 times, carl will win 5 times.

To find probability that carl will beat his friend, we take the probability of Carl winning. Simple!

The probability is  5/ 12

one endpoint of AB has coordinates (-3,5) If the coordinates of the midpoint of AB are (2,-6),what is the length of AB?
avanturin [10]
We know that (-3,5) is the location of one of the endpoints.... and we know the midpoint is at (2,-6)... .now.. what's the distance between those two guys?

\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
&({{ -3}}\quad ,&{{ 5}})\quad 
%  (c,d)
&({{ 2}}\quad ,&{{ -6}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
d=\sqrt{[2-(-3)]^2+[-6-5]^2}\implies d=\sqrt{(2+3)^2+(-6-5)^2}
\\\\\\
d=\sqrt{5^2+(-11)^2}\implies d=\sqrt{25+121}\implies d=\sqrt{146}

so, the distance "d" from the midpoint to that endpoint is that much.  And the distance from the midpoint to the other endpoint is the same "d" distance, because the midpoint is half-way in between both endpoints.

so, the length of AB is twice that distance, or   \bf 2\sqrt{146}
