Can someone help me with a two step equatio that is x=2

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]

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.

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

                       (To record discounting)  

Thus, Cash & Loss are debited, & Notes Receivable & Interest are credited.

The solution to the indices is 50.

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;

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.

236.5 ft depth will the pressure acting on the object.

The m is the slope, and b is the y-intercept, therefore f(x) = mx + b.

You are given the value of m = 4.44 (lb/in2) for every 10 feet of descent; however, you need f(x) to be a function of the depth in inches, thus you must determine what m is for every inch of fall.

120 inches are equal to 10 feet multiplied by (12 inches per foot).

Every 120 inches of fall, then, gives rise to m = 4.44.

m = 4.44 / 120 = 0.037 for each inch of fall

Consequently, f(x) = 0.037x + b

The fact that f(0) = 15 and b = 15 can be used to find b.

f(x) = 0.037x + 15 is the equation as a result.

Set f(x) = 120 and work out x to obtain the pressure at that point.

120 = 0.037x + 15 0.037x = 105 x, or 105 / 0.037 = 2837.8 inches, or roughly 236.5 ft.

Total interest is determined by the addition of all the interest payments.

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.

According to the image, 1 centimeter represents 32 feet of the actual structure, which means there is a 1:32 scale factor, let's calculate then the number of centimeters in total to know the height:

1 foot = 30.48 cm

32 feet = x

x= 30.48 x 32/ 1 = 975.36 cm

Based on this the height can be expressed as  1/975.36.

In this polygon, all angles are right angles. The area of this polygon = 334 ft²

To calculate the area of a regular polygon, just apply the formula below: Half of a perimeter multiplied by apothem equals area. What it means is as follows: The perimeter is the sum of the lengths of all the sides. A segment known as an apothem joins the midpoint of any perpendicular side to the midpoint of a polygon.

The equation for the area of a regular polygon with n sides is [l2n]/[4tan(180/n)]. where n is the number of sides and l is the length of the sides of the polygon.

To calculate the area of a regular polygon, use the formula Area = (number of sides length of one side apothem)/2.

A data set's attributes are enumerated through descriptive statistics. You can use inferential statistics to test a hypothesis or determine whether your data can be applied to a larger population.

Two sets of pupils with scores from various classes are highlighted, Using descriptive statistics, determine the mode of the following data: Using descriptive and inferential statistics, determine the z score for the given data.

Measurements of variability and measures of central tendency make up descriptive statistics (spread). Mean, median, and mode are examples of central tendency metrics. Variability measures include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.

correlation analysis, A set of independent variables and a dependent variable, such as Hypothesis Tests, are related in regression models. To compare entire populations or evaluate the correlations between variables, hypothesis testing is utilised along with samples and confidence intervals.
