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 add the variables X and Y 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 values of 45 or more 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 discrete distribution, the expected value is the sum of each outcome multiplied by it's respective probability, 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

Marcella Heinz purchased office supplies at Office Emporium for $107.64. She then purchased an English-Spanish dictionary for $1

Sliva [168]

The total amount of tax on her purchases to the nearest cent will be $9.97

Explanation

Marcella Heinz purchased office supplies for $107.64 and then she purchased an English-Spanish dictionary for $16.95

So, the total amount of her purchases $=\$107.64+\$16.95=\$ 124.59$

On the total amount of the purchases, she paid state sales tax of 7.5% and the county tax of 0.5%

So, the amount of the state sales tax $=\$124.59*7.5\%= \$124.59*0.075=\$9.34425$

and the amount of county tax $=\$124.59*0.5\% =\$124.59*0.005 = \$0.62295$

Thus, the total amount of tax on her purchases $=\$9.34425+\$0.62295= \$9.9672 \approx 9.97$ (Rounded to the nearest cent)

Can someone plz help me it is timed I will give Brainliest IF IT IS CORRECT

Artyom0805 [142]

Answer:

C. 1.15x because adding 15% to the cost of the haircut is the same as multiplying the cost by 1.15.

Step-by-step explanation:

This answer is correct because, adding 0.15x (or 15%) to the total amount is the same as multiplying the cost by 1.15. This is because, the 1 that is added to 0.15 represents the total, since we are just multiplying instead of adding to it.

Hope this helps! :D
