Simplify the expression: 12x+3x+4x

Answer:

Option C

Step-by-step explanation:

Given :-

And we need to find out the equation of the line .We are here given slope and a point . So we can use the slope point form of the line. As ,

\(:\sf\implies m ( x - x_1)= y - y_1 \\\\\sf:\implies \dfrac{-1}{8}(x -0)= y - (-4) \\\\\sf:\implies \dfrac{-x}{8}= y +4 \\\\\sf:\implies \boxed{ \sf\red{y = \dfrac{-x}{8}-4}}\)

Hence the option C is correct.

Answer: A quadratic function is a polynomial function of form f(x) = ax^2 + bx + c where a,b, and c are constants, and a is not equal to zero.

The given functions are:

8 - 5x = 4(3x - 1)

(4a + 2)(2a - 1) + 1 = 0

2y + 2(3y - 5) = 0

2b(b - 7) + b = 0

The quadratic function(s) among them are:

2. (4a + 2)(2a - 1) + 1 = 0

2b(b - 7) + b = 0

The first one 8 - 5x = 4(3x - 1) is linear and not a quadratic function, and the third one 2y + 2(3y - 5) = 0 is also linear, not a quadratic function.

Note that to identify a quadratic function, we can look for the pattern of x^2 or y^2 in the equation.

Also, we could expand the second degree polynomials in the form (ax^2+bx+c) and check if there are x^2 or y^2 term on both sides of the equation.

The number she'd have is:

Explanation:

First, let's see which number is in the tens place and which number is in the ones place (the units place).

In the number 548, the place value of 5 is hundreds, the place value of 4 is tens, and the place value of 8 is ones (or units).

So if Sera adds two to the units, she'll have 10. But, since we can't write the number as 5410 (that would be a totally different number), we just write 0 in the units place, and shift 1 to the tens place, which gives us :

550

That's not all, since we also add 1 to the tens:

Let us remember the Pythagoras theorem by a diagram

That is, in a rectangle triangle the square of the measure of the longer side (the hypotenuse) is equal to the sum of the squares of the measures of the other two sides.

To solve the question, we have to identify the longer side (the hypotenuse) and apply the theorem.

Looking at the picture, we identify that:

Therefore the side that we have to find is the side a, in the diagram above. From the Pythagoras Theorem, we must have :

Therefore, to finish we take the square root on both sides and consider only the positive square root, because we are finding a length.

We conclude that the hypotenuse measures 12.7 , where we have approximated to the nearest tenth as required in the question.

The number of buses are 3 they took if each van holds 6 students and each bus holds 20 students.

What are the number of buses?

Let's use V and B to represent the number of vans and buses, respectively.

We know that:

V + B = 5 (since there were 5 vehicles in total)

6V + 20B = 72 (since there were 72 students in total)

We can use the first equation to solve for V in terms of B:

V = 5 - B

Then we can substitute this expression for V into the second equation:

6(5 - B) + 20B = 72

30 - 6B + 20B = 72

14B = 42

B = 3

The additional factors that might have an effect on the stress levels of tea drinkers are called confounding variables. Confounding variables are variables that are not the main focus of the study but may have an impact on the results.

The term used to describe these additional factors that might have an effect on the stress levels of tea drinkers is "confounding variables." Confounding variables are extraneous factors that can affect the relationship between two variables of interest and can lead to incorrect conclusions about the relationship. In this case, the higher proportion of yoga practitioners and the increased exercise among tea drinkers could be considered confounding variables because they may be influencing the observed relationship between tea drinking and lower stress levels, rather than tea consumption alone.

Standard deviation does not mean independent events.

No, the standard deviation is a measure of the spread or variability of a set of data. It measures how much the individual data points in a dataset deviate from the mean or average of the dataset.

Independence, on the other hand, refers to the relationship between two or more events, where the occurrence of one event does not affect the probability of the other event occurring.

Standard deviation is not directly related to the concept of independence. However, when calculating the standard deviation of a dataset, it assumes that each data point is independent and identically distributed. This means that the value of one data point does not affect the value of another data point, and that each data point is drawn from the same underlying distribution.

The absolute value of the elevation difference between the valley and sea level is 94 feet.

The absolute value of a number is the distance of that number from zero on the number line. It represents the magnitude or size of a quantity without considering its direction. In the given scenario, we are dealing with the elevation difference between a valley and sea level.

The valley is described as being 94 feet below sea level. To find the absolute value of the elevation difference, we need to ignore the negative sign and consider the magnitude of the difference.

In this case, since the valley is below sea level, the elevation difference is negative. However, when we take the absolute value, we disregard the negative sign and focus solely on the numerical value of the difference.

By applying the absolute value to the elevation difference of -94 feet, we remove the negative sign and consider only the magnitude. Thus, the absolute value of -94 is simply 94.

Therefore, the absolute value of the elevation difference between the valley and sea level is 94 feet. It indicates that the valley is 94 feet away from sea level in terms of elevation, regardless of the direction (above or below sea level). The absolute value provides a measure of the magnitude of the difference while disregarding the direction or sign associated with it.

Assets are the economic resources belonging to a business. Assets could be money in a cash register or bank account, or items such as property, fixtures and furniture, equipment, motor vehicles, and stock or goods for resale. An important asset in businesses which sell goods or services on credit is money owed to the enterprise by customers. This asset is known as debtors.

Capital is the value of the investment in the business by the owner(s). It is that part of the business that belongs to the owner; hence it is often described as the owner’s interest.

Liabilities are the debts owed by the firm. The main types of liabilities are creditors (money owed by the business to suppliers of goods and services), bank overdrafts and bank loans.

Answer:

133,860

Step-by-step explanation:

The baker was going to sell his house for 145,500 but he found that no one came to buy, so he decreased the amount by "8%".

* No we have our key elements:

- Starting amount = 145,500

- Rate of change = 8%

* We will get the "8%" of the number 145,500

- Firstly, "8%" means 8/100

- So, 0.08 will be our new rate of change.

* 145,500 will be multiplied by 0.08 to find the final answer because when we talk about the percentage of a number, we are going to talk about a part of it.

- 145,500 × 0.08 = 133,860 ; the same as

145,500 × 8/100 = 133,860

5 ≤ L ≤ 35

Step-by-step explanation:

Let w represent the width of the rectangle.

The perimeter (P) of the rectangle is given by:

P = 2w + 2L

Where L is the length of the rectangle.

We know that w = 30 cm and that the perimeter is between 100 and 160 cm. We can now set up our compound inequality:

100 ≤ 2(30) + 2L ≤ 160

100 ≤ 90 + 2L ≤ 160

10 ≤ 2L ≤ 70

We can now divide both sides by 2 to solve for L:

5 ≤ L ≤ 35

Therefore, the compound inequality that represents the graph of a rectangle with a width of 30 centimeters and a perimeter of 100 centimeters to 160 centimeters is:  5 ≤ L ≤ 35

Answer:

5.25

Step-by-step explanation:

Let the number be x. The equation is:

24 - x / x = 3

We can rearrange this equation to solve for x:

24 - x = 3x

21 = 4x

x = 21/4

x = 5.25

So the value of the number is 5.25.

The null and alternative hypotheses can be stated as follows:

c. H0: µ = 12, Ha: µ ≠ 12

The null hypothesis (H0) assumes that the population mean content of the bottles is 12 ounces, indicating perfect adjustment of the filling machine. The alternative hypothesis (Ha) states that the population mean content is not equal to 12 ounces, suggesting that the machine is not in perfect adjustment.

The rejection region for α = 0.01 can be specified as:

c. |t| > 2.68

This means that we would reject the null hypothesis if the absolute value of the calculated t-statistic is greater than 2.68.

To calculate the p-value, we need the t-statistic corresponding to the sample mean and standard deviation. With a sample mean of 11.88 ounces, a standard deviation of 0.35 ounces, and a sample size of 49, we can calculate the t-statistic. The p-value represents the probability of observing a sample mean as extreme as the one obtained, assuming the null hypothesis is true.

The p-value cannot be determined without the t-statistic value or the corresponding degrees of freedom.

Without the p-value, we cannot draw a definitive conclusion. To make a conclusion, we would compare the calculated t-statistic to the critical t-value based on the chosen significance level (α = 0.01). If the calculated t-statistic falls within the rejection region (|t| > 2.68), we would reject the null hypothesis. If the calculated t-statistic falls outside the rejection region, we would fail to reject the null hypothesis.

In order to create 728 millilitres of the medication, 273 millilitres of component A are required.

A compound in chemistry is a material comprised of two or more separate chemical elements mixed together in a certain proportion. Chemical connections that are challenging to break are created when the elements interact with one another.

Compound A:Compound B ratio in the medication is 3:5. In other words, there are 3 millilitres of compound A and 5 millilitres of compound B for every 3+5=8 millilitres of the medicine.

We may set up a percentage using the ratio of compound A to the total volume of the medicine to determine how much compound A is required to make 728 millilitres of the drug:

3 ml x 3 ml x 3 ml

-------- = ----------

728 ml total, 8 ml overall

If we cross-multiply, we obtain:

8(x) = 3(728)

273 milliliters of compound A are needed to make 728 milliliters of the drug.

What are proportions?

In mathematics, a proportion is a statement that two ratios are equal. It expresses the relationship between two or more quantities that are directly proportional to each other. A proportion can be represented as an equation of the form:

a/b = c/d

To determine the amount of compound A needed to make 728 milliliters of the drug, we need to use the given ratio of 3 milliliters of compound A to 5 milliliters of compound B.

Let's start by finding the ratio of compound A to the total amount of ingredients (A+B) in the drug:

3 : (3+5) or 3:8

This means that for every 8 milliliters of the drug, 3 milliliters of compound A are used.

To find out how many milliliters of compound A are needed for 728 milliliters of the drug, we can set up a proportion:

3/8 = x/728

where x represents the amount of compound A needed.

To solve for x, we can cross-multiply:

8x = 3*728

8x = 2184

x = 273

Therefore, 273 milliliters of compound A are needed to make 728 milliliters of the drug.

Answer: 1/3

Step-by-step explanation: To subtract mixed numbers, first subtract the fractions.

Notice here however that we have 1/6 - 5/6

which will give us a negative fraction.

Since this will cause us a lot of trouble, instead,

let's rewrite the first mixed number.

We can do this by thinking of 3 and 1/6 as 2 + 1 and 1/6 or 2 + 7/6

by changing 1 and 1/6 into an improper fraction.

So 3 and 1/6 can be written as 2 and 7/6.

So we have 2 and 7/6 -  2 and 5/6.

Now, subtract the fractions.

So we have 7/6 - 5/6 which is 2/6.

Then subtract the whole numbers.

2 - 2 is 0.

However, we don't need to include 0 in our answer.

We can write our answer as 2/6.

However, 2/6 is not in lowest terms.

So divide the numerator and denominator by 2 to get 1/3.

So 3 and 1/6 - 2 and 5/6 is 1/3.

a) Let X represent the random variable of the number of Californians in the sample of 6 people who have been to Disneyland.

b) X is a binomial random variable because it records the number of successes (people who have been to Disneyland) in a fixed number of trials (6 people).

c) The probability of exactly 3 people having been to Disneyland is 3.05.

This is calculated using the binomial probability formula:

P(x=3) = (6³) * (0.41³) * (0.59³)

= 3.05

d) The mean of X is 2.46. This is calculated using the binomial mean formula:

μ = n * p

= 6 * 0.41

= 2.46

e) The standard deviation of X is 1.2. This is calculated using the binomial standard deviation formula:

σ = √[n * p * (1 - p)]

= √[6 * 0.41 * (1 - 0.41)]

= 1.2

f) The probability that the number of Californians in the sample that have been to Disneyland is within one standard deviation of the mean is 68.27%.

The prize is p100,000.00, and we can define this as the 100%.

Now, we could say:

"Each member receives the same percentage of the price as the total percentage of the project that he/she did"

Then:

Member A did 25% of the total project.

Then he gets an amount X.

X = 25%

p100,000.00 = 100%

We can solve this system for X as:

X = (25%/100%)*p100,000.00 = p25,000.00

Now we can use the samme aproach for the other members:

Member B did 40% of the total project:

Then he gets an amount X.

X = 40%

p100,000.00 = 100%

X = (40%/100%)*p100,000.00 = p40,000.00

Member C did 25% of the total project.

Then he gets an amount X.

X = 25%

p100,000.00 = 100%

X = (25%/100%)*p100,000.00 = p25,000.00

Member D did 10% of the total project.

Then he gets an amount X.

X = 10%

p100,000.00 = 100%

X = (10%/100%)*p100,000.00 = p10,000.00

Now, we also could divide the price evenly between the four members:

p100,000.00/4 = p25,000.00

So they all get the same amount, but i think that the actual solution to this problem is the other one.
