compare numbers.
Performs arithmetic operations (+, –, *, /) as well as comparison or relational operations (<, >, =); the latter are used to compare numbers.
Comparison or relational operations, such as <, >, =, allow for comparing numbers. They determine if a number is less than, greater than, equal to, or not equal to another number, enabling decision-making and comparisons within arithmetic and programming operations.
When comparing numbers, you can use various relational operators to determine the relationship between them. Here are the commonly used comparison operators:
Less than (<): This operator compares two numbers and returns true if the first number is smaller than the second number. For example, 5 < 10 is true.
Greater than (>): This operator compares two numbers and returns true if the first number is larger than the second number. For example, 10 > 5 is true.
Less than or equal to (<=): This operator compares two numbers and returns true if the first number is smaller than or equal to the second number. For example, 5 <= 5 is true.
Greater than or equal to (>=): This operator compares two numbers and returns true if the first number is larger than or equal to the second number. For example, 10 >= 10 is true.
Equal to (==): This operator compares two numbers and returns true if they are equal. For example, 5 == 5 is true.
Not equal to (!=): This operator compares two numbers and returns true if they are not equal. For example, 5 != 10 is true.
These comparison operators allow you to compare numbers and make decisions based on their relationships within arithmetic or programming operations.

Buses arrive at a specified stop at 15-minute intervals starting at 7:00 AM. If a passenger arrives at the stop at any time between 7:00 AM and 7:30 AM, find the probability that he waits less than 5 minutes for a bus.
The probability that the passenger waits less than 5 minutes for a bus is approximately 0.45.
The probability that a passenger arriving at a specified stop between 7:00 AM and 7:30 AM waits less than 5 minutes for a bus can be calculated as follows:
There are 31 buses that arrive at the stop between 7:00 AM and 7:30 AM, since they arrive at 15-minute intervals. If a passenger arrives at a random time within this 30-minute period, then there is a uniform distribution of possible arrival times.
If we assume that the passenger's arrival time is uniformly distributed over this period, then the probability that the passenger waits less than 5 minutes for a bus is equal to the proportion of the 30-minute interval during which a bus arrives within 5 minutes of the passenger's arrival time.
Since each bus arrives at 15-minute intervals, the probability that a bus arrives within 5 minutes of the passenger's arrival time is the same for each of the 31 buses.
Therefore, the probability that the passenger waits less than 5 minutes for a bus is equal to the proportion of the 30-minute interval that is covered by the 31 buses arriving within 5 minutes of the passenger's arrival time.
To calculate this probability, we can consider the total time covered by the 31 buses that arrive within the 30-minute interval, and then subtract the time during which these buses arrive more than 5 minutes before or after the passenger's arrival time.
There are 2 buses that arrive before the passenger's arrival time, and 2 buses that arrive more than 5 minutes after the passenger's arrival time, so we need to subtract the time covered by these 4 buses.
The time covered by the 31 buses that arrive within the 30-minute interval is 31 × 15 = 465 minutes. The time covered by the 4 buses that arrive before or after the passenger's arrival time is 4 × 15 = 60 minutes. Therefore, the time covered by the 31 buses that arrive within 5 minutes of the passenger's arrival time is 465 - 60 = 405 minutes.
The probability that a bus arrives within 5 minutes of the passenger's arrival time is therefore 405/30 = 13.5/1 or approximately 0.45.

Suppose you draw a tiny circle with a 90 degree sector. Is it a dilation of the original circle shown in the image below? Why or why not?
If you draw a tiny circle with a 90-degree sector, it is not a dilation of the original circle because a dilation is a transformation that changes the size of an object while preserving its shape.
What is a dilation?In a dilation, all corresponding points in the original and the transformed shapes lie on a line passing through the center of dilation, and the scale factor of the dilation determines the ratio of the corresponding lengths of any two segments that join corresponding points.
In the case of the tiny circle with a 90-degree sector, the sector has a different shape than the original circle, and the sector has a larger perimeter than the corresponding arc of the original circle. Therefore, the sector is not a dilation of the original circle.
Furthermore, a 90-degree sector of a circle can be obtained by cutting a part of the original circle and thus cannot be obtained by dilation alone.

Solve for x
3(x-7)=6
Answer:
\(x=9\)
Step-by-step explanation:
To solve the given equation:
3(x-7) = 6
We first distribute the 3 to the terms inside the parenthesis:
3x - 21 = 6
Next, we add 21 to both sides of the equation to isolate the term with the variable:
3x - 21 + 21 = 6 + 21
Simplifying, we get:
3x = 27
Finally, we divide both sides by 3 to solve for x:
3x/3 = 27/3
Simplifying, we get:
x = 9
Therefore, the solution to the equation 3(x-7) = 6 is x = 9.
Answer: x = 9
Step-by-step explanation:
3(x-7)=6
multiplying to remove brackets-
3x-21 = 6
solve equation-
3x = 27
x = 27/3

The expression (3.6 * 10^-5) / (1.8 * 10^2) can be calculated as = 2 * 10^-7
A canonical, normal, or standard form of a mathematical object is a conventional manner of presenting that item as a mathematical expression in mathematics and computer science. It is frequently the one that gives the simplest representation of an item and allows it to be identified in a unique fashion.
A quantity is said to be stated in standard form if it is written as the product of a power of ten and a number higher than or equal to one but less than ten (or scientific notation).
The expression (3.6 * 10^-5) / (1.8 * 10^2) can be calculated as follows:
=3.6 * 10^-5 / (1.8 * 10^2)
= (3.6 / 1.8) * (10^-5 / 10^2)

A box had twice as many grapes as a basket. Once 2 kg of grapes were added to the basket, it contained 0.5 kg more than the box. How many kilograms of grapes are in the basket now? (it's not 3kg or 1.5kg)
Answer:
3.5kg
Step-by-step explanation:
Let original weight of grapes in box be X and weight of grapes in basket be Y.
From the first sentence
X = 2Y (weight in box = 2 times weight in basket) --- (1)
If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2
From the second statement
Y + 2 = X + 0.5
Subtracting Y from the LHS gives 2 = X - Y + 0.5
Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5 --- (2)
Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg
But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg

Melanie invests money in an account paying a simple interest of 6. 2% per year. If no money will be added or removed from the investment, what should she multiply her current balance by to find her total balance in a year in one step?
Answer:
P(1.062)
Step-by-step explanation:
According to the given information
Melanie invests her money into an account that pays simple interest.
And the simple interest rate = 6.2%
So we can write = 6.2% = 6.2/100 = 0.062
So the rate is 0.062
Now let us assume the invested money is $P
now the maturity after one year with simple interest = P + (P x r x t)
principal amount = P
rate of interest r = 0.062
time in years t = 1
so the matured value = P + (P x 0.062 x 1)
so the matured value = P + (0.062P)
so the matured value = P[1 + 0.062 ]
matured value = 1.062(P)
So in on step, we can write the matured value with simple interest = principal x (1 + (r/100))
so r = 6.2%
So, the answer is P(1.062)

Simply use cross multiplication :
The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equals to symbol. Cross multiplication is a method for comparing fractions.
Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.
\(\frac{a}{15}=\frac{4}{5}\)

The probability of of a random student having blue eyes and dark hair
is 35% .
let consider the total students in the school be (U) = 100%
out of them ,
students having blue eyes (A) = 60%
students having dark hair (B) = 55%
students with neither blue eyes nor dark hair (A∪B)' = 20%
let the students with blue eyes and dark hair be (A∩B) = x %
Then according to the set theorem
U = n(A∪B) + n(A∪B)'
U = n(A) + n(B) - n(A∩B) + n(A∪B)'
100 = 60 + 55 - x +20

B) non-negative.
C) infeasible..
D) redundant.
When the addition of a constraint to a linear programming problem does not change the solution, it is said to be redundant. The correct answer is D) redundant.
A constraint in a linear programming problem is said to be redundant if its addition to the problem does not change the solution. In other words, the constraint is already satisfied by the current solution and does not impose any additional restrictions on the feasible region.
In contrast, an unbounded constraint allows for an infinite range of solutions, a non-negative constraint requires that the variables be greater than or equal to zero, and an infeasible constraint cannot be satisfied by any solution.
Therefore, if the addition of a constraint does not change the solution of a linear programming problem, it is considered to be redundant. I.e, the correct answer is D) redundant.

What is the length of the hypotenuse?
C =
yards
Answer:
The length of the hypotenuse is 10 yards.
Step-by-step explanation:
Given that this is a right triangle, you could apply the Pythagorean Theorem to it. Although I'm not exactly sure, given as there's no indication in your question.
The Pythagorean Theorem is a^2 + b^2 = c^2, for context.
So, 6^2 + 8^2 = ?^2.
6^2 = 36
8^2 = 64
64 + 36 = 100
However, 100 isn't the side length of c, it's c squared. To "unsquare" it, you need to find the square root of it.
In this case, the square root of 100 is 10.
6^2 + 8^2 = 10^2. Makes sense, right?
36 + 64 = 100
Hope this helps.
