Can you show that this is a parallelogram? Explain if you agree or disagree.

Answer:

\(y=-\,(x+1)^2+3\)

Step-by-step explanation:

Notice that the vertex of the parabola is at (-1, 3), so we can start the expression of the quadratic in vertex form as:

\(y=a\,(x--1)^2+3\\y = a\,(x+1)^2+3\)

we can now find the coefficient "a" by using another point the parabola goes through, like for example (0,2):

\(y = a\,(x+1)^2+3\\2=a\,(0+1)^2+3\\2=a+3\\a=2-3\\a=-1\)

So the final expression for the parabola in vertex form is:

\(y=-\,(x+1)^2+3\)

Answer:

11.2

Step-by-step explanation:

Given the linear equation :

2.6(5.5p-12.4)=127.92 ; solve for p

Open the bracket :

14.3p - 32.24 = 127.92

Add 32.24 to both sides

14.3p - 32.24 + 32.24 = 127.92 + 32.24

14.3p = 160.16

Divide both sides by 14.3

14.3p/14.3 = 160.16/ 14.3

p = 11.2

The value of p = 11.2

Answer:

-9/10

Step-by-step explanation:

Answer:

1/10

Step-by-step explanation:

First, you must change the denominator of -2/5 to an even one. I changed it to 10 by multiplying the fraction by 2. Multiplying the fraction by 2 will give you -4/5. To add 1/2, find 1/2 of 10/10. 1/2 of 10/10 is 5/10, so add 5/10 to -4/10 and you get 1/10. Hope this helps. <3

Step-by-step explanation:

Answer:

Step-by-step explanation:

it would be "c" because the question asks for the number that makes the inequality true

4x≤ x+3

the graph in c is saying that every number that is 1 or less than 1 makes the inequality true. so lets take -7 as an example

4 x -7=-28

-28+3=-25

-25 is greater than -28 so the inequality is true. the reason why graph d doesnt work is because if we plug in 2 into the equation, then 4x =8 and x+3=5

5 is not greater than 8 so it doesnt work

Answer:

\(x = \frac{2}{3}n\pi\)

Step-by-step explanation:

Given

\(Tanx + Tan2x + Tan3x = Tanx.Tan2x.Tan3x\)

Required

Find x

Equate the given expression to 0

\(Tan\ x + Tan\ 2x + Tan\ 3x - Tan\ x\ .Tan\ 2x\ .Tan\ 3x = 0\)

Factorize:

\(Tan\ x + Tan\ 2x + Tan\ 3x(1 - Tan\ x\ .Tan\ 2x) = 0\)

Subtract both \(Tan\ 3x(1 - Tan\ x\ .Tan\ 2x)\) from both sides

\(Tan\ x + Tan\ 2x + Tan\ 3x(1 - Tan\ x\ .Tan\ 2x) - Tan\ 3x(1 - Tan\ x\ .Tan\ 2x) = 0 - Tan\ 3x(1 - Tan\ x\ .Tan\ 2x)\)

\(Tan\ x + Tan\ 2x = - Tan\ 3x(1 - Tan\ x\ .Tan\ 2x)\)

Divide both sides by: \((1 - Tan\ x\ .Tan\ 2x)\)

\(\frac{Tan\ x + Tan\ 2x}{(1 - Tan\ x\ .Tan\ 2x) } = - Tan\ 3x\)

In trigonometry:

\(Tan(3x) = Tan(x + 2x) = \frac{Tan\ x + Tan\ 2x}{(1 - Tan\ x\ .Tan\ 2x) }\)

So,

\(\frac{Tan\ x + Tan\ 2x}{(1 - Tan\ x\ .Tan\ 2x) } = - Tan\ 3x\)

is equivalent to:

\(Tan\ 3x = - Tan\ 3x\)

Collect Like Terms

\(Tan\ 3x+Tan\ 3x = 0\)

\(2Tan\ 3x = 0\)

Divide through by 2

\(Tan\ 3x = 0\)

In trigonometry:

If

\(Tan\ x= 0\) ,

Then \(x=2n\pi\)

Where \(n \ge 0\)

So, in this case:

\(3x = 2n\pi\)

\(x = \frac{2}{3}n\pi\)

Based on the given information, the second brand, Cola, is the more affordable option in terms of cost per milliliter compared to Co Fizz.

To determine which brand of cola is more expensive, we need to compare the cost per unit volume for each brand.

For the first brand, Co Fizz, a pack contains 4 bottles, and each bottle has a volume of 500 ml. The cost of the pack is $2.50. Therefore, the total volume in a pack is 4 * 500 ml = 2000 ml. To find the cost per milliliter (ml), we divide the total cost by the total volume: $2.50 / 2000 ml = $0.00125 per ml.

For the second brand, Cola, a pack contains 10 bottles, and each bottle has a volume of 330 ml. The cost of the pack is $2. Therefore, the total volume in a pack is 10 * 330 ml = 3300 ml. To find the cost per milliliter (ml), we divide the total cost by the total volume: $2 / 3300 ml ≈ $0.000606 per ml.

Comparing the two brands, we can see that the cost per milliliter for Co Fizz is $0.00125, while the cost per milliliter for Cola is approximately $0.000606.

Since the cost per milliliter for Co Fizz is higher than the cost per milliliter for Cola, it can be concluded that Co Fizz is more expensive in terms of price per unit volume.

Answer:

0.5587 = 55.87% probability that the sample mean would differ from the true mean by less than 1.1 dollars.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The cost of 5 gallons of ice cream has a variance of 64 with a mean of 34 dollars during the summer.

This means that \(\sigma = \sqrt{64} = 8, \mu = 34\)

Sample of 38

This means that \(n = 38, s = \frac{8}{\sqrt{38}}\)

What is the probability that the sample mean would differ from the true mean by less than 1.1 dollars ?

P-value of Z when X = 34 + 1.1 = 35.1 subtracted by the p-value of Z when X = 34 - 1.1 = 32.9. So

X = 35.1

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{35.1 - 34}{\frac{8}{\sqrt{38}}}\)

\(Z = 0.77\)

\(Z = 0.77\) has a p-value of 0.77935

X = 32.9

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{32.9 - 34}{\frac{8}{\sqrt{38}}}\)

\(Z = -0.77\)

\(Z = -0.77\) has a p-value of 0.22065

0.77935 - 0.22065 = 0.5587

0.5587 = 55.87% probability that the sample mean would differ from the true mean by less than 1.1 dollars.

Answer:

123201

Step-by-step explanation:

This is an arithmetic sequence of common difference 2 and starting value 1,

So we can use the formula for an arithmetic sequence  if we know what is the order of the last term.

Then first use the formula for the nth term to find "n":

\(a_n=a_1+(n-1)d\)

where d = 2, first term = 1 and last term = 701

\(a_n=a_1+(n-1)d\\701=1+(n-1)*2\\700=(n-1)*2\\350=n-1\\n = 351\)

Knowing this, we can estimate the partial sum:

\(S=n\,\frac{a_1+a_n}{2} \\S=351\,\frac{1+701}{2} \\S=351\,*\,351\\S = 123201\)

For the given transactions, the general journal, T accounts, and trial balance is attached.

In the given case, it is required to record all transactions using the general journal, post them into corresponding T accounts. After posting all transactions, ending balances are calculated. The ending balances are used to create a Trial Balance.

The general journal is a book of original entries where the raw business transactions is recorded according to the date events occur. It is the first place where data is recorded . The general journal for the provided data is attached (figure 1).

Each transaction from the journal to corresponding T-accounts and their ending balances are calculated by subtracting credits from debits for accounts with debit balance and subtracting debits from credits for account with credit balance. A T-account is an informal term which is used for a set of financial records that use double-entry bookkeeping.  It is a graphical representation of a general ledger where business’ transactions are recorded. It consists of the an account title at the top, a debit side on the left, and a credit side on the right. It is called a T-account because the bookkeeping entries are laid out in a way that resembles a T-shape. The T-account for the given data is attached (figure 2 and 3).

Trial balance is prepared by entering corresponding ending balances from T accounts and calculating the sums of debit and credit. A trial balance refers to a bookkeeping worksheet where the balances of all ledgers are compiled into debit and credit account column totals that are equal. The general purpose is to ensure that the entries in a company’s bookkeeping system are mathematically correct. The trial balance for the given data is attached (figure 4).

A repeating decimal is acceptable to use during calculations when you require a certain level of precision

A repeating decimal is acceptable to use during calculations when you require a certain level of precision, but it's important to keep in mind that the result will be an approximation rather than an exact value.

It is commonly used in situations where a rounded value is sufficient and the level of precision doesn't significantly impact the final result.

On the other hand, you should convert a repeating decimal to a fraction for calculations when you need an exact value or when further mathematical operations or comparisons are required.

Converting a repeating decimal to a fraction allows for precise calculations and eliminates any potential rounding errors associated with working with decimal approximations.

Converting a repeating decimal to a fraction involves identifying the repeating pattern and expressing it as a fraction. This allows for exact calculations and maintains the mathematical properties of fractions.
