A. What is the probability that this couple spends 45 dollars or more?
guapka [62]

Using the probability table, it is found that:

  • a) There is a 0.25 = 25% probability that this couple spends 45 dollars or more.  
  • b) The expected amount the couple actually has to pay is $36.85.

Item a:

To find the probabilities involving the total cost, we have to <u>add the variables X and Y</u> from the table, then:

P(X = 30) = P(X = 15|Y = 15) = 0.2

P(X = 35) = P(X = 15|Y = 20) + P(X = 20|Y = 15) = 0.15 + 0.15 = 0.3

P(X = 40) = P(X = 15|Y = 25) + P(X = 20|Y = 20) + P(X = 25|Y = 15) = 0.05 + 0.15 + 0.05 = 0.25

P(X = 45) = P(X = 20|Y = 25) + P(X = 25|Y = 20) = 0.1 + 0.1 = 0.2

P(X = 50) = P(X = 25|Y = 25) = 0.05

The probability involving <u>values of 45 or more</u> is:

P(X \geq 45) = P(X = 45) + P(X = 50) = 0.2 + 0.05 = 0.25

0.25 = 25% probability that this couple spends 45 dollars or more.

Item b:

For a <em>discrete distribution</em>, the expected value is the <u>sum of each outcome multiplied by it's respective probability</u>, hence, involving the 10% discount for prices above $45:

E(X) = 0.2(30) + 0.3(35) + 0.25(40) + 0.9[0.2(45) + 0.05(50)] = 36.85

The expected amount the couple actually has to pay is $36.85

Find distance. round to the nearest tenth of necessary. A (0,3) and B (0, 12)
frozen [14]

Answer:

Step-by-step explanation:

The distance formula is d=\sqrt{(x2-x1)^{2} +[tex]\sqrt{(0-0)^{2} + (12-3)^{2}}\sqrt{0 + (9)^{2}}

\sqrt{(9)^{2}}

\sqrt{(y2-y1)^{2} }

\sqrt{81} = 9
