The scatter plot shows the average monthly temperature, x , and a family's monthly heating cost, y , for 24 different months.

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

[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]

The length of the hypotenuse is 13 units

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

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

When the number of times you roll an odd number increases, the theoretical probability that you roll an even number would decrease.

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.

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

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)

P(x ≥ 1) = 0.9375

Chances of getting just one female or exactly one boy

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

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.

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.

difference in monthly payment = 1834.62 - 1207.70

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

                           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

Therefore , the solution to the given problem of slope intercept comes out to be  dy/dx = -1/2.

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)

Given that the diameter of the circle is 6.4 centimeters.

The radius of the circle is thus half of the diameter that is 3.2 centimeters.

The area of the circle is given by the formula:

[tex]A = \pi r^2[/tex]

Substitute the value of r = 3.2 in the formula:

[tex]A = (3.14) (3.2)^2\\\\A = 32.15[/tex]

The area of the circle is 32.15 square centimeters.
