Answer:
a) P( [tex]Y^{C}[/tex] | X ) = 0.180
b) P(Y | [tex]X^{C}[/tex] ) = 0.998
Step-by-step explanation:
Let
P(X) - Probability that he acts hungry
P(Y) - Probability that he had ate dinner,
Given,
P(X | Y) = 0.5
P(X | [tex]Y^{C}[/tex] ) = 0.99
P(Y) = 0.9
a.)
P( [tex]Y^{C}[/tex] | X ) = [tex]\frac{P( X | Y^{C} ). P(Y^{C} ) }{P( X | Y^{C} ). P(Y^{C} ) + P( X | Y ) . P (Y) }[/tex]
= [tex]\frac{(0.99)(0.1)}{(0.99)(0.1) + (0.5)(0.9)} = \frac{0.099}{0.549}[/tex] = 0.180
⇒P( [tex]Y^{C}[/tex] | X ) = 0.180
b.)
P(Y | [tex]X^{C}[/tex] ) = [tex]\frac{(1 - P(X | Y ) ) . P(Y)}{P( X^{C} ) } = \frac{(1 - P(X | Y ) ) . P(Y)}{ 1 - P( X ) }[/tex]
= [tex]\frac{(1 - 0.5)(0.9)}{1 - [(0.99)(0.1) + (0.5)(0.9) ]} = \frac{(0.5)(0.9)}{1 - [(0.099) + (0.45) ]} = \frac{0.45}{1 - [0.540]} = \frac{0.45}{0.451}[/tex] = 0.998
⇒P(Y | [tex]X^{C}[/tex] ) = 0.998

Step-by-step explanation:
We are given a table that displays the current value of information technology giant, Cisco Inc. Using the table below, determine the closing price of Cisco Systems stock the previous day. A 9-column table with 1 row. Column 1 is labeled 52-week high with entry 15.34. Column 2 is labeled 52-week low with entry 14.88. Column 3 is labeled stock with entry C S C O. Column 4 is labeled Dividend with entry 0.15. Column 5 is labeled yield percentage with entry 0.997. Column 6 is labeled P E with entry 11.97. Column 7 is labeled Volume 100 s with entry 563,063. Column 8 is labeled close with entry 15.04. Column 9 is labeled net change with entry negative 0.02. a. $14.86 c. $15.06 b. $14.90 d. $15.04
Answer:
$15.06 answer C
Step-by-step explanation:
The previous day's closing price of Cisco Systems stock was $15.06. The correct option is c.
The closing price of Cisco Systems stock the previous day was $15.06.
We can see from the table that the "close" price listed in column 8 is $15.04 and the "net change" listed in column 9 is negative 0.02. This means that the stock price decreased by $0.02 from the previous day's closing price.
To find the previous day's closing price, we need to add the net change of -$0.02 to the current day's closing price of $15.04:
$15.04 + (-$0.02) = $15.02
Thus, the correct option is c.

Lee watches tv for 3 hours per day. During that time the tv consumes 250 watts per hour. Electricity costs 12 cents/1 kilowatt-hour. How much does it cost to run the tv does 30 days?
Answer:
270 dollars
Step-by-step explanation:
He's going to watch 90 hours of tv in 30 days, so multiply 90 hours x 250 watts, Which is 22500 watts over 30 days, then convert to kilowatts which would be 22.5 kilowatts total. He used .25 kilowatts an hour every day. Then multiple 22.5 x 12 cents to get your answer 270. He paid 270 dollars for electricity for the tv.

What percent of 24 is
18?
The value 18 is 75% of the number 24.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that there are two numbers 24 and 18. The percentage will be calculated as,
Percent = ( 18 / 24) x 100
Percent = 0.75 x 100
Percent = 75%
