The difference in elevation between the bottom of the canyon and the birds nest is 679.8 feet.
What is a numerical expression ?
A numerical expression is an statement written in form of numbers with mathematical operations.
According to the given question
A bird flies from the bottom of a canyon that is59 1/5 feet below sea level to a nest that is 620 3/5 feet above sea level.
59 1/5 feet
(59×5 + 1)/5
59.2 feet
Let assume that the sea level is at 0 feet.
= (620×5 + 3)/5
= 620.6 feet.
From the given data we write an expression which is the difference in elevation between the bottom of the canyon and the bird nest is
( 620.6 ) - ( -59.2 ) feet
= 620.6 + 59.2 feet
= 679.8 feet.
Hence, The elevation difference between the birds' nest and the canyon's base is 679.8 feet.

3. Consider drawing a hand of five cards. What is the probability that:
a. The first card is a king.
The probability that the first card is a king is 0.08.
Which is probability?
Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is stated. To forecast the likelihood of events, probability has been introduced in mathematics. The likelihood that something will occur is essentially what is meant by probability. This is the fundamental theory of probability, which is also used to calculate the probability distribution, and it is from it that you will discover the likelihood of various outcomes in a random experiment.
A deck of cards contains 52 cards.
Sample space = 52
there are 4 kings in a deck of cards.
Therefore the probability that the first card is a king = 4/52
=0.0769 approximately = 0.08

Nora spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -12.4°F. Between 9am and noon, the temperature increased by 7.6°F. Between noon and 3pm, the temperature went up 13.1°F. Between 3pm and 6pm, the temperature dropped 1.2°F. What was the temperature at 6pm?
As per given data of recording of increasing and decreasing of temperature during different day times , the temperature at 6pm is 7.1°F.
As given in the question,
The decimal value of the temperature at 6 pm was 7.1°F
Nora's temperature recording chart in winter can be tabulated as follows:
Time Change in Temperature (°F) Temperature Reading (°F)
9 am ----- -12.4
12 noon +7.6 -4.8
3 pm +13.1 +8.3
6 pm -1.2 +7.1
Calculation by way of addition / subtraction of decimal is as follows:
-12.4°F +7.6°F = -4.8°F (increase in temperature from 3 pm to 6 pm)
-4.8°F + 13.1°F = 8.3°F (increase in temperature from 3 pm to 6 pm)
8.3°F - 1.2°F = 7.1°F (drop in temperature from 3 pm to 6 pm)
Overall change in temperature from 9 am to 6 pm is 19.5°F (increment)
Therefore, as per given data of recording of increasing and decreasing of temperature during different day times , the temperature at 6pm is 7.1°F.

What is the first term of the series?
The first term of the geometric progression will be 81.
What is geometric progression?When there is a constant between the two successive numbers in the series then it is called a geometric series. In other words, every next term is multiplied by that constant term to form a geometric progression.
Given that the common ratio of the geometric series is ( 2 / 3 ) and the sum of the first four terms is 171.
The first term of the geometric series will be calculated as:-
[tex]S_n = a_1\dfrac{(r^n-1)}{r-1}[/tex]
[tex]171 = a_1\dfrac{(\dfrac{2}{3}^3-1)}{\dfrac{2}{3}-1}[/tex]

a₁ = 9 x 9
a₁ = 81

Roxanne claims that all linear equations represent proportional relationships. Which statement explains whether Roxanne is correct?
A Yes, because all linear equations have graphs that are straight lines.
B No, because not all linear equations have graphs that pass through the origin.
C Yes, because all proportional relationships can be expressed as linear equations.
D No, because not all proportional relationships can be expressed as linear equations.
Roxanne claims that all linear equations represent proportional relationships. So, this statement "Yes, because all linear equations have graphs that are straight lines." makes him correct.
When there is a proportionate relationship between two variables, the other variable changes at a consistent pace regardless of how the first variable changes, grows or shrinks. A constant ratio between the two variables can be thought of as the constant rate.
Equations, graphs, and tables that use proportions can be used to show proportional relationships. A broad structure is followed by the proportional relationship equation, which will be taught in this session. Straight lines are used to illustrate the graphs. The tables are sets of numbers that are always paired in the same ratio.
Hence the correct option is A

A polynomial is a mathematical statement that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminates (also known as variables) and coefficients. Numerous branches of mathematics and science use polynomials. For instance, they are used to define polynomial functions, which show up in contexts ranging from basic chemistry and physics to economics and social science, and they are used in calculus and numerical analysis to approximation other functions. Polynomial equations are used to encode a wide range of problems, from simple word problems to complex scientific problems. In higher mathematics, polynomials are used to build algebraic varieties and polynomial rings, two fundamental ideas in algebra and algebraic geometry.

The values which satisfy the inequality y < 4 are - 4, - 1, 1, 3, 3.9. 3.99, 3.999.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
An inequality y < 4 is given.
This states that the variable y is strictly less than 4 it could be 3.999999.. but not 4.
Then the value that makes the inequality true are,
- 4, - 1, 1, 3, 3.9. 3.99, 3.999,
If the inequality was y ≤ 4 then 4 could have included 4 only but not 4.001.

What is a number line?A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
In Mathematics, a number line can be used to determine the difference between two numbers such as -2.2 and 8.4. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.
Now, we can determine the distance by taking the difference between both values as follows:
Distance = -2.2 - 8.4
Distance = -10.6.
