1. y = -1.15x + 102.8 is the equation of the line of best fit.
2. Using the line of best fit's equation, the estimated price is: $62.55.
What are Equations?A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
We have LHS = RHS (left hand side = right hand side) in every mathematical equation.
To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
A statement is not an equation if it has no "equal to" sign.
According to our question-
1. Making use of the two points (20, 80) and (72, 20)
Slope (m) is equal to change in y/change in x, or (80 - 20)/(20 - 72) = 60/-52.
Slope is -1.15 meters.
Change y - b = m to m = -3 and (a, b) = (72, 20). (x - a)
y - 20 = -1.15(x - 72) (x - 72)
y - 20 = -1.15x + 82.8
y = -1.15x + 82.8 + 20
y = -1.15x + 102.8
The best line of fit is the equation y = -1.15x + 102.8.
2. To calculate the monthly heating expense, y, for a month with an average temperature of 35°F (x), enter x = 35 into the formula: y = -1.15x + 102.8.
y = -1.15(35) + 102.8
y = 62.55
The estimated monthly expenditure is $62.55.

if the expression 4x + 2(x - 4) is equivalent to x +2 then what is the value of x?
Answer:
x=2
Step-by-step explanation:
4x + 2(x - 4) is equivalent to x +2
first, distribute. 4x+2x-8
next, combine like terms. 6x-8
6x-8 = x+2
we need to group all the variable terms on one side, and all the constant terms on the other side of the equation. (6x-8)+(8-x)=(x+2)+(8-x)
get rid of the parenthesis. 6x-8+8-x=x+2+8-x
combine like terms. 6x-x-8+8=x-x+2+8
solve. 5x=10
divide both by 5. 5x/5=10/5

X^2+2xy-2y^2+x=2 find gradient at point (-4,1)
Therefore , the solution to the given problem of slope intercept comes out to be dy/dx = -1/2.
A slope-intercept form is precisely what?After you are certain if Y = mx + b, the gradient intercept approach can be employed. By using just one particular point on the line and its slope, the direction form is a way to represent an axiom for a line. The slope is defined as such rise across run and is represented first by point form (x,y), and may be calculated using the slope intercept method, y = mx + b. (0, b). By using just one specific statement on the vector and its slope, the direction form is a technique to write a linear model for a line.
Here,
Given : x² +2xy - 2y² +x =2
thus,
To find the gradient at point (-4,1) :
We have to find the dy/dx
so,
=> 2x + 2y + 2xdy/dx -2ydy/dx +1 =0
=> dy/dx (2x-2y) = -(2x+ 2y) -1
=>dy/dx = -(2x+2y) -1 / (2x-2y)
So , at the point (-4,1)
=> dy/dx = -(-8 + 2) -1 / (-8 -2)
=>dy/dx = 5/-10
=>dy/dx = -1/2
Therefore , the solution to the given problem of slope intercept comes out to be dy/dx = -1/2.

Selkirk Company obtained a $15,000 note receivable from a customer on January 1, 2021. The note, along with interest at 9%, is due on July 1, 2021. On February 28, 2021, Selkirk discounted the note at Unionville Bank. The bank’s discount rate is 12%.
Required:
Prepare the journal entries required on February 28, 2021, to accrue interest and to record the discounting for Selkirk. Assume that the discounting is accounted for as a sale.
A journal entry is a format used in accounting to record transactions. The amount we owe someone else that we must get in the future is known as notes receivable.
What is Notes receivable?Notes receivable are claims for which official documents of credit, like promissory notes, are issued as proof of debt. In most cases, the credit instrument has a minimum term of 30 days and imposes an interest payment obligation on the debtor.
Given the following information:
Note receivable $15,000
Rate of interest 9%
Discount rate 12%
Period 2 months
Preparing journal entry to record accrued interest
To prepare the journal entry, we must first calculate the interest. We can compute interest by multiplying the notes receivable, the interest rate, and the period, i.e.
Interest = Notes receivable × Rate of interest × Period
Interest = 15000 × 0.09 × 2/12
Interest = 225
Now we can prepare the journal entry
Date Particulars Debit ($) Credit($)
February 28, 2016 Interest receivable 250
Interest 250
To record accrued interest
Preparing the journal entry to record discounting
To begin preparing the Journal entry, we must first calculate the necessary data.
We can calculate the cash as the difference between Maturity Value and Discount. That is,
Cash = Maturity Value – Discount
The value of Maturity is unknown. We can compute it as the sum of the receivable notes and interest. That is,
Maturity Value = Notes receivable + Interest
Interest =Notes receivable × Rate of interest × Period
= $15,000 × 0.1 × 6/12
= $1,500 × 0.5
= $750
Maturity Value = Notes receivable + Interest
= $15,000 + $750
= $15,750
Discount =Maturity Value × Discount rate × Period
= $15,750 × 0.12 × 4/12
= $1,890 × 0.33
= $630
Finally, we can calculate cash
Cash = Maturity Value – Discount
= $15,750 − $630
= $15,120
Loss on sale = Cash – Notes receivable - Interest
= $15,120 − $15,000 − $250
= $130
Finally, we can prepare our journal entry.
Date Particulars Debit ($) Credit($)
February 28,2016 Cash 15,120
Loss on sale 130
Notes receivable 15,000
Interest 250

You roll a number cube and record an odd number 12 times in a row. As the number of times you roll an odd number increases, what happens to the theoretical probability that you roll an even number? (Please show step by step explanation)
When the number of times you roll an odd number increases, the theoretical probability that you roll an even number would decrease.
How is the probability of rolling an even number affected ?As the number of times you roll an odd number increases, the theoretical probability that you roll an even number decreases. This is because the probability of rolling an even number is inversely proportional to the number of times you roll an odd number.
If you are rolling a fair die, the probability of rolling an even number is 3/6 or 1/2, and the probability of rolling an odd number is also 3/6 or 1/2.
As the number of times you roll an odd number increases, the number of rolls that are left for an even number decreases, thus the probability of rolling an even number decreases as well.
For example, if you roll the die 10 times and 6 of them are odd numbers, the probability of rolling an even number in the remaining 4 rolls is 4/4 or 1 (100%) because you are guaranteed to roll an even number.

and 7 yellow pens. You randomly pull a pen
from the bag, put it back, and then pull out
another one.
What is the probability of not getting a yellow and then not getting a yellow? Write
your answer as a fraction.
Answer:
[tex]\textrm{P(no yellow on two picks )} = \dfrac{16}{121}[/tex]
Step-by-step explanation:
The total number of pens is 1 + 3 + 7 = 11 out of which 7 are yellow.
(We don't really care what color the other pens are since we are interested only in the yellow pens)
[tex]\textrm{P(yellow on first pick )} = \dfrac{\textrm{Number of yellow pens}}{\textrm{Total number of pens}} = \dfrac{7}{11}[/tex]
The probability of not getting a yellow on first pick is the complement of this probability and is 1 less than the probability of picking an yellow
[tex]\textrm{P(not yellow on first pick )} = 1- \dfrac{7}{11} = \dfrac{4}{11}[/tex]
Since we are putting back the pen after the first pick, the total number of pens as well as pens of each color remain the same.
Therefore the probability of not getting a yellow on second pick is the same as the first pick and is [tex]\dfrac{4}{11}[/tex]
The combined probability of not getting an yellow on both picks is the product of these probabilities
[tex]\textrm{P(no yellow on two picks )} = \dfrac{4}{11}\cdot \dfrac{4}{11} = \dfrac{16}{121}[/tex]

In a right triangle, given legs of lengths 5 and 12, find the length of the hypotenuse.
The length of the hypotenuse is 13 units
How to find the length of the hypotenuse.From the question, we have the following parameters that can be used in our computation:
Legs = 5 and 12 units
The length of the hypotenuse of the right triangle can then be calculated using
Hypotenuse² = Leg 1² + Leg 2²
Substitute the known values in the above equation, so, we have the following representation
Hypotenuse² = 5² + 12²
So, we have
Hypotenuse² = 169
Take the square roots
Hypotenuse = 13
Hence, the hypotenuse is 13 units

Monthly payment for United bank = $1207.70, monthly payment for capitol bank =$1834.62. Total interest from United bank = $75600 and from capitol bank = $135000.
What is total interest?
Total interest is determined by the addition of all the interest payments.
what would be the monthly payment and total interest from each bank?
United bank offers mortgage at an APR of 4.2%
APR means annual percentage rate.
mortgage is offered for the period of 15 years.
initial principal amount of Marcy = $120000
we need to determine the monthly payment from United bank.
at first, we will determine the rate of interest per month.
monthly interest rate = (4.2) / (100 × 12) = 0.0035
1 year = 12 months
15 years = 15×12 = 180 months
monthly payment is calculated by the formula = [rate + (rate) / {(1+rate)∧month}⁻¹] ×principal
monthly payment = [ 0.0035 + (0.0035) / {(1+0.0035)∧180}⁻¹] ×120000
= $1207.70
from united bank monthly payment = $1207.70
Now we calculate the monthly payment from Capitol bank.
APR for capitol bank = 4.5%
number of years for which mortgage is issued = 25 years
number of months = 12×25 = 300.
monthly interest rate = (4.5) / (100×12) = 0.00375
monthly payment for capitol bank = [0.00375 + (0.00375) / {(1+0.00375)∧300}⁻¹] × 120000
= 1834.62
monthly payment from Capitol bank = $1834.62
total interest from Capitol bank = principal money × yearly interest rate × time period.
Total interest = 120000 × 4.5/100× 25
= $135000 for the Capitol bank
Total interest from United bank = principal amount × yearly interest × time period
= 120000× 4.2/100 × 15
total interest from united bank = $75600
United bank has lower total interest.
difference in monthly payment = 1834.62 - 1207.70
= 626.92 dollars

The solution to the indices is 50.
What is an Indices?Index (indices) is the power or exponent which is raised to a number or a variable. The plural of index is indices. Indices contain constants and variables. The constant is a value which cannot be changed and a variable quantity can be assigned any number or its value can be changed.
Indices are a convenient tool in mathematics to correctly denote the process of taking a power or a root of a number. Taking a power is simply a case of repeated multiplication of a number with itself while taking a root is just equivalent to taking a fractional power of that same number.
8^1/3 / 5^-2
Applying the necessary laws of indices;
