The percentage increase in the price of the notebook is 15%.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100.
The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Finding the increase in the price of the notebook:
$3.80 - $3.30 = $0.50
Dividing the increase by the original amount:
0.50 / 3.30 = 0.1515
To change to a percent multiply by 100 and round off to significant numbers:
0.1515 *100 = 15.15% or, 15%.
Thus, the percentage increase in the price of the notebook is 15%.

A restaurant serves a bowl of candies to their customers. The bowl of candies Gabriel receives has 10 chocolate candies, eight coffee candies, and 12 caramel candies. After Gabriel chooses a candy, he eats it. Find the probability of getting candies with P (chocolate or coffee)
Answer:
3/10
Step-by-step explanation:
Let the total number of candies =
10 chocolate candies + 8 coffee candies + 12 caramel candies = 30 candies
Probability of picking a chocolate candy = P(chocolate) = 10/30
Probability of picking a coffee candy = P(chocolate) = 8/30
Hence, the probability of getting candies with P (chocolate or coffee)
= P(chocolate) + P(coffee)
= 10/30 + 8/30
= 18/30
= 3/10
Therefore, the probability of getting candies with P (chocolate or coffee) is 3/10

Why is 3 a polynomial?
A variable has a degree of zero and no exponent. Each constant polynomial has a degree of zero.
A polynomial is what?A polynomial only uses addition, subtraction, multiplication, and non-negative integer exponentiation of the variables as its operations. In mathematics, the term "indeterminate" is frequently used to describe variables. A polynomial is an equation that combines variables, constants, and exponents while using addition, subtraction, multiplication, and division of numbers (No division operation by a variable).
A variable has no exponent, the degree is 0. The degree of each constant polynomial is zero .
Since 3 can be expressed as [tex]3 X 0[/tex] and is a constant polynomial, it has a degree of [tex]0[/tex].

Steve ran a 26-mile race at an average speed of 4 miles per hour. If Adam ran the same race at an average speed of 3 miles per hour, how many minutes longer did Adam take to complete the race than did Steve?
Answer:
Adam took 132 minutes longer than Steve.
Step-by-step explanation:
Let's find the time that takes Steve and Adam to complete the race. We will use the equation:
[tex] V = \frac{d}{t} [/tex]
Where:
d: is the distance = 26 miles
t: is the time =?
V: is the speed
For Steve we have the following time:
[tex] t_{s} = \frac{d}{V_{s}} = \frac{26 mi}{4 mi/h} = 6.5 h*\frac{60 min}{1 h} = 390 min [/tex]
And the time of Adam is:
[tex] t_{a} = \frac{d}{V_{a}} = \frac{26 mi}{3 mi/h} = 8.7 h*\frac{60 min}{1 h} = 522 min [/tex]
So, the difference between the time of Adam and Steve is:
[tex] \Delta t = t_{a} - t_{s} = 522 min - 390 min = 132 min [/tex]
Hence, Adam took 132 minutes longer than Steve.

To open a safe five numbers must be entered on a keypad. The keypad contains numbers 0-9. The numbers have to be entered in a certain order
to open the safe.
a. What are the TOTAL number of possible ways you can enter five numbers to open this safe (if there are NO restrictions on the numbers that
may be chosen)?
b. If no numbers repeat, then how many entries are possible?
c. What is the PROBABILITY that the safe's five numbers do not repeat? Write your answer as a percent rounded to the nearest tenth.
Answer:
30.2%
Step-by-step explanation:
a. For each slot there are 10 possible numbers (0-9). Since there are no restrictions, the number in each slot is independent of the other. We can calculate the total number of possibilities using the product rule.
N = 10 × 10 × 10 × 10 × 10 = 10⁵
b. For the first slot, there are 10 possibilities.
For the second slot, we cannot repeat the number that we used in the first slot, so there are 9 possibilities.
For the third slot, we cannot repeat any of the previous numbers, so there are 8 possibilities.
For the fourth slot, we cannot repeat any of the previous numbers, so there are 7 possibilities.
For the fifth slot, we cannot repeat any of the previous numbers, so there are 6 possibilities.
The total number of combinations without any repetitions are:
10 × 9 × 8 × 7 × 6 = 30,240
c. The probability that the safe's five numbers do not repeat is:
P = favorable outcomes / possible outcomes
P = 30,240 / 10⁵ = 30.2%

Step-by-step explanation:
the perimeter of a rectangle is 48 yards. The length is 14 yards.
Answer:
10 yards
Step-by-step explanation:
We know that to find the perimeter you have to multiply the length and width by 2 and add
We already know that the length is 14 yards
Multiply 14 by 2
14*2=28
Subtract 48 by 28 (the total of both the length and width multiplied by 2)
48-28=20
Divide 20 by 2
20/2=10
And your answer is 10 yards as the width
10+10+14+14=48 yards

Express your answer in fraction and decimal form. Solve on paper. Then check your work on Zearn. The farmer sold kg or kg of pears
In fraction form, this is 6.375/8.5, or 3/4.In decimal form, this is 0.75.
What is fraction?Fraction is a mathematical expression which represents a part of a whole. It consists of a numerator and a denominator which are separated by a fraction bar. The numerator is the number of parts and the denominator is the total number of parts in the whole. Fractions can be used to represent parts of a whole number or parts of a physical object. Fractions can also be used to express ratios or rates.
To solve on paper, we can use the following equation:
Pears = 8.5 kg - (3/4 x 8.5 kg)
Pears = 8.5 kg - (6.375 kg)
Pears = 2.125 kg
Therefore, the farmer sold 2.125 kg of pears at the farmer's market in fraction form, and 0.75 in decimal form.

What is logically equivalent example?
Two statements are logically equivalent if they have the same truth value in all possible circumstances, meaning that they are either both true or both false in any given context.
For example, the statement "All dogs are mammals" is logically equivalent to the statement "All non-mammals are not dogs." Although the statements use different words and phrasing, they convey the same information and are both true.
Another example would be the statement "x>2" is logically equivalent to the statement "x>=3" because they both would have the same solutions.
Logical equivalence is important in logical reasoning, proof and in computer science where it is used to determine if two statements are logically equivalent which leads to simplify the boolean expressions.
