Answer:
4=x y=325
Step-by-step explanation:
60x + 20 = 65x
group the variables
20=5x
because you subtracted 60x from both
4=x
because you divided 5 from both
now substitute 5 for x
65×5 is 325
y=325
Answer: D) Adding heat to the reaction
Answer with Step-by-step explanation:
Since the given event is binary we can use Bernoulli's probability to sove the problem
Thus for an event 'E' with probability of success 'p' the probability that the event occurs 'r' times in 'n' trails is given by

Part a)
For part a n = 11 , r =9, p = 0.75
Applying values we get

Part b)
For part b n = 20 , r = 16 , p=0.75
Applying values we get
