The probability of getting 2 at least once is 1/6.
What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur.So, the probability of getting a 2 at least once:
The sample space will be (refer to the image attached below).Formula of probability: P = favourable events/total events
At least once, we need to get 2 and a maximum of 7.So, favorable events = 7, and the total number of events will be 6×7 = 42.Now, substitute the values in the formula as follows:
P = 7/42P = 1/6Therefore, the probability of getting 2 at least once is 1/6.

Mr. Mole left his burrow and started digging his way down. A represents Mr. Mole's altitude relative to the ground (in meters) after t minutes.
Based on the model that shows the altitude of Mr. Mole relative to the ground, the rate at which Mr. Mole was digging was 2.3 meters down per minute.
How to find the rate?When given a linear function, the rate that the model progresses is given by the slope. The slope in a linear function can be found as:
y = mx + b
m = slope
b = y-intercept
In the model given for Mr. Mole's digging, which is -2.3t - 7, the slope is -2.3.

Given the credit union banker's assets and liabilities, their total net worth is C. $233,693.
What is the net worth?The net worth of an individual is the difference between their assets (long-term and short-term) and their liabilities (long-term and short-term).
The net worth is equivalent to the equity of a business, which refers to the net assets owned by the stockholders after paying off all debts.
Assets:Car Value = $29,850
Savings Accounts = $12,409
Treasury Bonds = $10,000
Checking Account Balance = $19,419
Home Value = $194,450
Total assets = $266,128
Liabilities:Car loan = $10,560
Student Loans = $13,824
Credit Card Balance = $8,051
Total liabilities = $32,435
Net worth = $233,693 ($266,128 - $32,435)

Standard Form: x³ + 6x² - x - 30Degree: 3Leading Coefficient: 1Leading Term: x³Step-by-step explanation:
Standard form has terms arranged from the highest to the lowest power
Degree is the highest power
Leading coefficient is the coefficient of the highest term
Leading term is the term containing the highest power
(x + 3) (x - 2)(x + 5)
(x + 3) (x - 2) = x² + x - 6 using the FOIL method
(x² + x - 6)(x +5) = x³ + 6x² -x - 30
Step-by-step explanation:
come on, we explained this already in previous questions. if you understood the explanations there, you should have been able to some that here without any problems.
again, standard form is the sorted polynomial from highest variable exponent to the lowest (as the potential constant at the end represents the x⁰ term).
the leading term is the first term on the left (with the highest exponent).
the leading coefficient is the factor in this leading term.
degree is the highest exponent used in the polynomial (again, given by the leading term).
so, what is still the problem ?
i have a slight problem with your handwriting. it is unclear, if there is 7x³ or 17x³. or 13x or 3x.
1.
p(x) = 17x³ + 4x² + 6 - 9x⁴
now, just sort this from the highest to the lowest exponent.
p(x) = -9x⁴ + 17x³ + 4x² + 6
if it should be 7x³ instead of 17x³, please use 7x³ in the polynomial.
degree = 4
leading coefficient = -9
leading term = -9x⁴
2.
p(x) = 1 + 13x - 9x⁵
again sort from highest to lowest exponent
p(x) = -9x⁵ + 13x + 1
again, if it should be 3x instead of 13x, please use 3x in the polynomial.
degree = 5
leading coefficient = -9
leading term = -9x⁵
3.
y = 9x² - x⁵ + x⁹
remember, y = f(x)
that is the same thing, means the same thing. it just gives the result variable a specific name.
again sort by exponent.
y = f(x) or p(x) or ... = x⁹ - x⁵ + 9x²
degree = 9
leading coefficient = 1
leading term = x⁹
4.
f(x) = (x+3)(x-2)(x+5)
this is really like the other question I just answered.
so, we always multiply 2 terms. that result we multiply by the third term. and if they're are more, then that result with the fourth term, and that with the 5th term,...
I usually start at the left :
(x+3)(x-2) = x² - 2x + 3x - 6 = x² + x - 6
now
(x² + x - 6)((x+5) = x³ + 5x² + x² + 5x - 6x - 30 =
= x³ + 6x² - x - 30
so,
f(x) = x³ + 6x² - x - 30
degree = 3
leading coefficient = 1
leading term = x³

When two straight lines or rays intersect at a single endpoint, an angle exists formed. If 2 and 3 exists complements, and m2= 55°, then m3 = 90 - 55 = 35 degrees.
What is meant by angle?When two straight lines or rays intersect at a single endpoint, an angle exists formed. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Complements sum to 90 degrees.
If 1 and 2 are complements and m1 = 35°, then
m2 = 90 - 35 = 55 degrees.
Now if 2 and 3 are complements, and m2= 55°,
then m3 = 90 - 55 = 35 degrees.
The complete question is:
Given: 1 and 2 are complements, 2 and 3 are complements, and m1 = 35°. Prove: m3 = 35° Complete the missing parts of the paragraph proof. By then, we know that angle 1 is congruent to angle 3.

In mathematics, an expression that was created using integer variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)
However, since they are not produced from integer constants and algebraic operations, transcendental numbers such as such and e are not algebraic.

An expression is considered rational if it can be reduced to a rational fraction using the properties of arithmetic operations (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions).If x shirts are bought, cost of x shirts at $5.75 = 5.75x

is $44 per day plus $0.25 per mile, what is the
maximum number of miles Julie can drive the car?
The maximum number of miles Julie can drive the car is 272 miles.
Let's check how:
Julie's budget for renting a car is $200.
number of days she'll rent a car is 3.
car rental per day is $44 + $0.25 per mile.
so to know maximum no. of miles she can drive
we'll first subtract the 3 days rent from Julie's budget = $200 - ( 3 x $44 )
= $200 - $132
= $132
Now, the left money is $68.
so, we will divide $68 by $0.25 to know how much miles she can drive.
