Answer:
s= 15 (nearest integer), 14.8 (to nearest 10ths)
Step-by-step explanation:
here you need to apply the cosine rule,

substituting the values,
u= 13, t=5 and angle S as 60 and solving will give you the answer 14.76 (2 dp)
Answer: 7/17
So there are 7 blue marbles and there are 17 marbles in total.
That means the probability of picking one blue marble is 7/17
X intercept- (0,250)
Y intercept- (0,100)
If you want me to explain I can!
