What is an angle addition postulate?According to the Angle Addition Postulate, an angle's measure is equal to the sum of the measures of any two adjacent angles. The Angle Addition Postulate can be used to determine the measurement of a missing angle or to determine the angle produced by two or more other angles.
Given:
The angle measures:
m∠DAE = 16° and m∠EDC = 64°.
The diagonals of the kite intersect at 90°.
(1).
In ΔAED,
the sum of all the angles of the triangle is 180°.
m∠DAE + m∠ADE + m∠AED = 180°
m∠ADE = 180 - 90 - 16
m∠ADE = 74°
According to the angle addition postulate,
m∠ADE + m∠EDC = m∠ADE
m∠ADE = (74 + 64)°
m∠ADE = 138°
From the property of kites,
m∠ADE = 138° = m∠ABC.
(2). m∠EBC = m∠EDC,
m∠EBC = 64°
In ΔBCD,
the sum of all the angles of the triangle is 180°.
m∠DBC + m∠BCD + m∠CDB = 180°
m∠BCD = 180 - 64 - 64
m∠BCD = 52°
Therefore, 138° = m∠ABC and m∠BCD = 52°.

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

February 28, 2016 Interest receivable 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

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

PLEASE HELP ASAP:
A bag has 1 speckled pen, 3 black pens,
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]
which of the following is true about statistics such as the sample mean or sample proportion?
A. A statistic is a constant.
B. A statistic is always known.
C. A statistic is a paraméter
D. A statistic is a random variable.
The correct option is option D) A statistic is a random variable.
We derive the above answer due to the following reason,
Any statistic is a random variable with its own distribution referred to as the sampling distribution as it is a function of sample values and there may be several samples taken from a given population.
The probability distribution of a statistic that is acquired by the continuous sampling of a particular population is called the sampling distribution. It outlines a variety of potential possibilities for a statistic, such as the mean or mode of a population's mean or the mode of a variable.
There are three standard types of sampling distributions in statistics:

A couple is starting a family and decides to have four children. Assume that the probability of having a boy or having a girl are equal. Find the probability model for the number of girls the couple has
Consequently, the probability of producing precisely one girl or exactly one male 0.25 + 0.25 = 0.5P(x = 1) = 4C1 * 0.5^1 * 0.5^3; 0.9375 ; 0.5
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty.
Due to this:
p = 0.5
Modeling the probability of how many females the couple has:
[tex]P(x =x) is equal to nCx * px * (1 - p) (n - x)\\P(x = 0) = 4C0 * 0.5^0 * 0.5^4 = 0.0625\\\=P(x = 1) = 4C1 * 0.5^1 * 0.5^3 = 0.25\\P(x = 2) = 4C2 * 0.5^2 * 0.5^2 = 0.375\\P(x = 3) = 4C3 * 0.5^3 * 0.5^1 = 0.25\\P(x = 4) = 4C4 * 0.5^4 * 0.5^0 = 0.0625[/tex]
likelihood of having at least one female
N = 4 trials in total.
P(x 1) is equal to p(x = 1) plus p(x = 2) plus p(x = 3) plus p(x = 4)
Employing the relation
P(x =x) is equal to nCx * px * (1 - p) (n - x)
use a calculator
P(x ≥ 1) = 0.9375
Chances of getting just one female or exactly one boy
3 females OR 3 boys OR 1 boy
P(x = 1)
P(x =x) is equal to nCx * px * (1 - p) (n - x)
P(x = 1) = 4 * 0.5 * 0.125
P(x = 1) = 0.25
The likelihood of getting one girl and three males or vice versa is 0.25
Consequently, the likelihood of producing precisely one girl or exactly one male
0.25 + 0.25 = 0.5P(x = 1) = 4C1 * 0.5^1 * 0.5^3 is 0.9375 ; 0.5

For the following two numbers, find two factors of the first number such that their product is the first number and their sum is the second number.
40,13
The two factors such that their product is the first number and their sum is the second number are 8 and 5.
What is a factor?A factor is defined as the number that divides another number, leaving no remainder.
In other words, if multiplying two numbers gives us a product, then the number we multiply is a factor of the product and divided by the product.
The factors of 40 and 13 such that their product is the first number and their sum is the second number = 8 and 5.
That is, 8×5 = 40
8+5 = 13
