Answer:
0.57
Step-by-step explanation:
Given that:
food = f ; c = clothes
P(f) = 0.76
P(C) = 0.49
P(fnC) = 0.28
Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the probability that the shopper also buys food?
P(f Given C) = P(f | C)
P(f | c) = p(fnC) / p(C)
P(f | c) = 0.28 / 0.49
P(f | c) = 0.5714
P(f | c) = 0.57
Answer:
48 times
Step-by-step explanation:
From the above question, we know that:
2 times = 1 kg of fertilizer
A crop requires 24 kg of fertilizer
Hence:
1 kg of fertilizer = 2 times
24 kg of fertilizer = x
Cross Multiply
x = 24 kg × 2 times/1 kg
x = 48 times
She need to fill the flask 48 times to make the required amount of fertilizer for the crop

Answer: See the attached image below for the filled out table</h3>
================================================================
Explanation:
For each value in the table, you will divide it over 200 because there are 200 people total in this survey. Doing so will give you the decimal form of the percent. From here you move the decimal point over 2 spots to the right to get it to percent form.
For instance, in the top left corner we have 104 people satisfied with plan A. This is out of 200. So 104/200 = 0.52 = 52% are satisfied with plan A. We'll write 52% in the top left corner. The other cells of the table are filled in a similar fashion.
An alternative route is possible. Since we are given a limited amount of choices (rather than fill in the blank), we can note that 8 is the smallest value in the table. This must mean that it corresponds to the smallest percentage in the list of options. Sure enough 8/200 = 0.04 = 4%. Then we have 24 as the next smallest item in the original table. It corresponds to the next smallest percentage 12%, and sure enough 24/200 = 0.12 = 12%. This process can be continued until you fill out the table. Keep in mind that this method only works if you are given a list of choices like this. Otherwise, it is ideal to use a calculator to compute the percentages.
Answer:
D. X= -100
Step-by-step explanation:
5×x/5=5×(-20) (reduce and multiply)
X= -100
Answer:
Average number of people ride ferry boat = 62 or 63 people
Step-by-step explanation:
Given:
Number of people ride ferry boat
58 59 60 61 62 63 64 65 66 67
Find:
Average number of people ride ferry boat
Computation:
Average mean = Sum of all observation / Number of observation
Average number of people ride ferry boat = [58 + 59 + 60 + 61 + 62 + 63 + 64 + 65 + 66 + 67] / 10
Average number of people ride ferry boat = [625] / 10
Average number of people ride ferry boat = 62.5
Average number of people ride ferry boat = 62 or 63 people
