Find the vertex:
x = 10/(-2) = -5! Yeah!
Answer:
0.22
Step-by-step explanation:
Let the events be:
A: the person is a woman
B: the person has high blood pressure
We want to find P(B/A), that is, the probability that a person has high blood pressure given that is a woman. We can use the following theorem:
P(B/A) = P(A∩B)/P(A)
P(A∩B) is the probability that a person is a woman and has high blood pressure. Given that there are 18 women with high blood pressure and 158 persons in total (81 + 77),
P(A∩B) = 18/158
P(A) is the probability that a person is a woman. Given there are 81 women and 158 persons in total,
P(A) = 81/158
P(B/A) = P(A∩B)/P(A)
P(B/A) = (18/158)/(81/158) = 0.22
In the given question, there are several important information's that have been given. based on these information's the correct answer to the question can be determined. It is already given that the selling price is $50. 50% off has already been declared.
Then
The amount of sale given on the violin = (50/100) * 50 dollars
= 25 dollars.
So the sale that has been given on the violin is $25.
Then the original price of the violin = (50 + 25) dollars
= 75 dollars
So the original price of the violin was $75.
Answer:
11.95 dollars
Step-by-step explanation:
Cost of one LED bulb = 6.95 dollars
Cost of changing one bulb = 3 dollars
Life of each bulb = 5 years.
In 10 years, only one time after 5 years the bulbs would have been changed
Hence cost of 100 lamps = 695 and
cost of changing once = 500
Total cost = 1195 dollars for 11 years
Divide this by 10 years to get average cost per year
Cost of 100 lamps per year = 1195/100 = 11.95 dollars
