Answer:

The price of a cold drink is 10 dollars.

Step-by-step explanation:

We can use proportion.

\frac{5 \:  ice \: creams}{125 \: dollars}  =  \frac{1 \: ice \: cream}{x}  \\  \\  \frac{5x}{5}  =  \frac{125}{5}  \\  \\ x = 25

So we found out that one ice-cream costs $25.00.

The statement said, "An ice cream costs 15 more than a cold drink"

In other words, A cold drink costs 15 dollars less than an ice cream.

So we would subtract.

25 - 15 = 10

So a cold drink costs $10.00.

Afina-wow [57]

Answer:

<u>1. P(C) =  5/7</u>

<u>2. P(T) =  4/7</u>

<u>3. P(C and T) =  3/7</u>

<u>4. P(C or T) =  6/7</u>

Correct statement and question:

A high school janitor has 140 keys on his key chain. Of these 140 keys, 100 open classroom doors, 80 open the door to the teachers' lounge, and 60 open classroom doors and the teachers' lounge. Using this information, answer each of the following questions.

Let C be the event that a randomly selected key opens a classroom and T be the event that a randomly selected key opens the teachers' lounge.

1. What is P(C), the probability that a key opens a classroom?

2. What is P(T), the probability that a key opens the teachers' lounge?

3. What is P(C and T), the probability that a key opens a classroom and the teachers' lounge?

4. What is P(C or T), the probability that a key opens a classroom or the teachers' lounge?

Source:

Question that can be found at chegg dot com

Step-by-step explanation:

1. Let's review the information given to us to answer the problem correctly:

Number of keys the high-school janitor has = 140

Number of keys that open classroom doors = 100

Number of keys that open   teachers' lounge = 80

Number of keys that open both = 60

2. What is P(C), the probability that a key opens a classroom?  

Let's recall the formula of probability:

Probability = Number of favorable outcomes/Total of possible outcomes

Substituting with the real given values:

P(C) = 100/140 = 5/7 (Dividing by 20 numerator and denominator)

<u>P(C) =  5/7</u>

3. What is P(T), the probability that a key opens the teachers' lounge?

Substituting with the real given values:

P(T) = 80/140 = 4/7 (Dividing by 20 numerator and denominator)

<u>P(T) =  4/7</u>

4. What is P(C and T), the probability that a key opens a classroom and the teachers' lounge?

Substituting with the real given values:

P(C and T) = 60/140 = 3/7 (Dividing by 20 numerator and denominator)

<u>P(C and T) =  3/7</u>

5. What is P(C or T), the probability that a key opens a classroom or the teachers' lounge?

P(C or T) = P(C) + P(T) - P(C and T)

Substituting with the real given values:

P(C or T) = 5/7 + 4/7 - 3/7

<u>P(C or T) =  6/7</u>

In a figure, m&lt;1=m&lt;2. Which property can be used to reason that m&lt;2=m&lt;1.
Aneli [31]

Answer: Symmetric property of equality

This is the idea that if x = y, then y = x. We can swap the left and right sides of an equation, and still mean the same thing. The same applies to congruences as well.

a department store holds a year-end clearance sale that includes a 19.8% discount on cosmetics. find the sale price of a bottle
Ivan

The sale price of a bottle of perfume is $40.16 if its original price was 50.07%.

What is discount?

By paying a charge or fee, a debtor might purchase the right to postpone payments to a creditor for a predetermined length of time through the financial mechanism known as discounting. In essence, the party who is currently owing money purchases the right to postpone payment until a later time.

Let the original price of the perfume bottle is, $50.07

The sale on the cosmetics is 19.8%.

So, the discount on the perfume bottle is,

50.07 x 0.198 = 9.91368

Therefore, the sale price of perfume is,

$50.07 - $9.91368 = $40.15614

Hence, the sale price of perfume is, $40.16
