False. A research paper is based on facts, that's why you have to do research on it. If it was all your own thoughts, you could just write down whatever.
For this case we can use the following trigonometric relationship to solve the problem:
Where,
C.O: opposite leg
h: hypotenuse
Substituting values we have:
Clearing x we have:
Making the corresponding calculations we have:
Answer:
The value of x is given by:
Answer:
0.74
Step-by-step explanation:
Data provided :
Customers carrying an American express card, P(A) = 24%
customers carrying a VISA card, P(V) = 61%
Customers carrying both the cards, P(A∩V) = 11%
Now,
probability that a customer of this department store carries a credit card that the store will accept i.e
Probability that the customer is carrying either American Express or VISA
P(A∪V) = P(A) + P(V) - P(A∩V)
or
P(A∪V) = 24% + 61% - 11%
or
P(A∪V) = 85% - 11%
or
P(A∪V) = 74% = 0.74
