A bag of marbles contains only the colors blue, yellow, and green.
If the probability of getting a yellow marble is 1/3, and the probability of getting a blue marble is 1/5, what is the probability of getting a green marble?
Answer:
[tex]\frac{7}{15}[/tex]
Step-by-step explanation:
Given parameters:
Marbles in the bag = blue, yellow, and green
Pr(yellow) = [tex]\frac{1}{3}[/tex]
Pr(blue) = [tex]\frac{1}{5}[/tex]
Unknown:
Pr(green) = ?
Solution:
Probability is the likelihood of an event to occur;
For this problem;
Pr(yellow) + Pr(blue) + Pr(green) = 1
[tex]\frac{1}{3}[/tex] + [tex]\frac{1}{5}[/tex] + Pr(green) = 1
Pr(green) = 1 - ( [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{5}[/tex] )
Pr(green) = 1 - [tex]\frac{8}{15}[/tex]
Pr(green) = [tex]\frac{7}{15}[/tex]

Step-by-step explanation:
Ariel is training for her pilot's license. The school requires students to learn from the teacher and learn in the simulator. Airplane tutoring costs $105 per hour, and the flight simulator costs $45 per hour. The school requires students to spend 4 more hours in airplane instruction than in the simulator. If Ariel can afford to spend $3870 on training, what is the maximum number of hours of training in an airplane and in a simulator she can afford in getting her license?
Answer: Simulator = 23 hours
Airplane = 27 hours
Step-by-step explanation:
Let the number of hours spent in the simulator be x.
Since the school requires students to spend 4 more hours in airplane instruction than in the simulator. Thai means that the number of hours spent in the airplane will be: x + 4
To determine the maximum number of hours of training in an airplane and in a simulator she can afford in getting her license will then be:
= 105(x+4) + 45(x) = 3870
105x + 420 + 45x = 3870
105x + 45x = 3870 - 420
150x = 3450
x = 3450/150
x = 23
Number of hours spent in simulator = 23 hours.
Number of hours used in airplane = 23 + 4 = 27 hours

A cab company charges $3 per cab ride, plus an additional $1 per mile driven. How long is a cab ride that costs $20?
Answer:
You will be able to ride 17 miles.
Step-by-step explanation:
So to get into the cab you need to pay 3 dollars. For every mile it will cost you 1 dollar. And you can only spend 20 dollars.
The first step to do is subtract 3 from 20.
This gives us 17.
Now that our cab cost is deducted we can divided 17 dollars by 1 dollar.
17 / 1 = 17.
You will be able to ride for 17 miles

seven times the sum of 4 and a number is -14
The value of the unknown number will be equal to -6.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that seven times, the sum of 4 and a number is -14. Let the unknown number be x.
The value of the unknown number will be calculated as,
7(4 + x) = -14
28 + 7x = -14

You divide 6 by 2/3
The number of pillows that she can make will be 9.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Jessica wants to make pillows for her couch. She has 6 yards of fabric. Each pillow uses 2/3 of a yard.
Then the number of pillows that she can make will be given by the division of the numbers 6 and 2/3. Then we have
⇒ 6 / (²/₃)
⇒ 6 x 3 / 2
⇒ 3 x 3
⇒ 9
The number of pillows that she can make will be 9.
