Complete question :
A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town. Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop
Answer:
0.000116
Step-by-step explanation:
Using the binomial probability relation :
Probability of success, p = 0.53
1 - p = 0.47
Number surveyed, n = 12
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability that none has heard of the coffee shop :
P(x = 0) = 12C0 * 0.53^0 * 0.47^12
P(x = 0) = 0.000116
Step-by-step explanation:
The easiest way to solve proportions is by cross multiplying.
2/43 = j/13
43j = 26
Now simply divide:
j = 26/43
Answer:
False
Step-by-step explanation:
2 is a solution because to circle is closed. All answers including 2 and above are solutions.
Part A H(t) 124 166 176 154 g(t) 76.8 125.6 174.4 223.2
Part B between 3 and 4 seconds, g(t) was able to catch up to H(t) in terms of height. At H(t)=g(t), this gives 3.03 seconds which is indeed between 3 and 4 seconds. Above 3.03 seconds, g(t) overtakes the height of H(t).
