X/3+7
co-efficient=1/3
how?
x/3 is also the same as x(1/3).
Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
Rickey got 1199 and Pedro got 1474. I got that by subtracting 275 from 2673 to get 2398. Than you divide 2398 to get 1199 which is Rickey's answer but to get Perdro you have to add 275 to get his answer of 1474.
Answer:
d. 10%
Step-by-step explanation:
1. Information to know
15 cards left in the deck, and 5 are diamond, to find the probability of the next 2 cards being diamond, one has to find the probability of the 1st card as a diamond, and then multiply it by the probability of the 2nd card being a diamond.
Remember, probability is;

2. Find probability 1
favorable out comes; diamond = 5
total outcomes; total cards = 15
probability is; 
Simplified; 
3. Finding probability 2
If the last card drawn was a diamond then the new numbers will be
favorable outcomes; 4
total outcomes; 14
Probability is; 
Simplified; 
4. Total probability
Now, one has to multiply the first probability by the second probability to find the probability of the event;

= 
= 0.095238
