Answer:
B.The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is possible, but very unlikely.
Step-by-step explanation:
Out of 1009 consumers a sample of 30 consumers is selected and asked the questions. So, the sample size is 30.
n = 30
Based on previous survey, 42% are comfortable with the drone. So in this sample, we can consider the probability of success to be 42%.
p = 42% = 0.42
q = 1 - p = 1 - 0.42 = 0.58
We want to find the probability of getting exactly 24 consumers who are comfortable with drones.
x = 24
Since, the sample size is fixed, the selections are independent and probability of success is constant, we can use the Binomial Probability to answer this problem. All the conditions of a Binomial Distribution are being satisfied.
According to the formula of Binomial Distribution, the probability of getting exactly x success among n trials is given as:
Using the values, we get:
Thus, the probability of getting exactly 24 consumers from a sample of 30 who are comfortable with drones is 0.00002, which is extremely small.
Since, the value of probability is a very small positive number, it indicates that event is possible but very unlikely. An impossible event has probability equal to 0.
Therefore, option B gives the correct answer.
Answer:
The answer is below
Step-by-step explanation:
Given that the minimum monthly requirements are 840 pounds of phosphoric acid, hence:
35 pounds of phosphoric acid mix A + 14 pounds of phosphoric acid mix B ≥ 840 pounds of phosphoric acid
35x + 14y ≥ 840
The minimum monthly requirements are 540 pounds of nitrogen, hence:
15 pounds of nitrogen mix A + 18 pounds of nitrogen mix B ≥ 540 pounds of nitrogen
15x + 18y ≥ 540
The minimum monthly requirements are 768 pounds of potash, hence:
16 pounds of potash mix A + 64 pounds of potash mix B ≥ 768 pounds of potash
16x + 64y ≥ 768
Also, x ≥ 0 and y ≥0.
Therefore the equations are:
35x + 14y ≥ 840
15x + 18y ≥ 540
16x + 64y ≥ 768
x ≥ 0 and y ≥ 0
Plotting with geogebra gives the graph below.
The point are (0,60), (48,0), (18,15), (32,4)
