Find the slope determined by the following pair of points (0,8), (2, 4)​

Answers

Answer:

Step-by-step explanation:

We use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the points (0,8) and (2,4). This gives

[tex]\frac{4-8}{2-0}=\frac{-4}{2}=-2[/tex]

as the slope.

Hello.

Since we have two points, and we are asked to find the slope of the line, let's use the slope formula:

[tex]\mathrm{m=\displaystyle\frac{y2-y1}{x2-x1}}[/tex]

Where

m is the slope

y2 is the y-coordinate of the second point

y1 is the y-coordinate of the first point

x2 is the x-coordinate of the second point

x1 is the x-coordinate of the first point

In this case, m is unknown, y2 = 4, y1 = 8, x2=2, x1=0

Plug in the values:

[tex]\displaystyle\frac{4-8}{2-0}[/tex]

[tex]\displaystyle\frac{-4}{2} =-2[/tex]

Therefore, the slope is -2.

I hope it helps!

Can some one help me. Asset capital and liability please

Answers

Answer:

I hope this helps you.

Step-by-step explanation:

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.

You are asked to make a list of possible 5-character passwords using the first 7 letters of the alphabet. How many distinct passwords can you make? Indicate whether this is a combination or permutation.

Answers

Using the permutation formula, as the order is important, it is found that 2520 distinct passwords can be made.

The order is important as abcde is a different password than edcba, hence the permutation formula is used.

What is the permutation formula?

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 5 letters are chosen from a set of 7, hence:

Answers

Answer:

B

Step-by-step explanation:

P(7,r) = 5040

[tex]P(n,r)=\dfrac{n!}{(n - r)!}\\\\\\n = 7 \\\\\dfrac{7!}{(7 - r)!}=5040\\\\\\7! = (7-r)!*5040\\\\(7-r)!=\dfrac{5040}{7*6*5*4*3*2*1}\\\\\\(7-r)!=\dfrac{5040}{5040}\\\\\\(7-r)!=1\\\\[/tex]

(7 - r)! = 1!

7 -r = 1

7 = 1 + r

7 - 1 = r

r = 6

Answer:

  12.  B or C

  13.  C

  14.  A

  15.  A

Step-by-step explanation:

These problems involve various counting techniques. For combinations and permutations, there are formulas to aid in the counting. For other situations, you may need to list possibilities.

__

12.

  P(7, r) = 5040 . . . . . given

  P(7, r) = 7!/(7 -r)! = 5040

  5040/(7 -r)! = 5040 . . . . . evaluate 7!

  (7 -r)! = 1 . . . . . . . . . . . multiply by (7-r)!/5040

We know that both 0! and 1! = 1, so this has two solutions:

  7 -r = 0   ⇒   r = 7

  7 -r = 1   ⇒   r = 6

Both choices B and C are correct.

The attached calculator output confirms this result.

The formula of choice C is correct:

  C(n, r) = n!/((n-r)!r!)

Similarly, the two Ns and two Ss are indistinguishable, so additional factors of 2! must be removed. The number of arrangements is ...

  9!/(4!2!2!) . . . . matches choice A

a man won a lotto jackpot and he spent 2/5 on luxury cars and 1/4 on buying a house. what fraction of his lotto earnings is remaining.​

Answers

The answer is 1/20 or 20
Explanation: find the lcd first which is 20 then 2/20 minus 1/20

The fraction of his lotto earnings that is remaining is 7/20.

What is a fraction?

A fraction is a portion of a whole or, more broadly, a set of equal pieces.

Let the total amount that the man won in the lotto jackpot is x.

Now, he spent 2/5 of the jackpot on luxury cars and 1/4 on buying a house, therefore, the total spending he will do is,

[tex]\dfrac{2x}{5}+\dfrac{x}{4}[/tex]

Now, the fraction of his lotto earnings that is remaining can be written as,

[tex]x-\dfrac{2x}{5}+\dfrac{x}{4}\\\\\\=\dfrac{x}{1}-\dfrac{2x}{5}-\dfrac{x}{4}\\\\\\=\dfrac{x \times 20}{1 \times 20}-\dfrac{2x \times 4}{5 \times 4}-\dfrac{x\times 5}{4\times 5}\\\\\\=\dfrac{20x-8x-5x}{20}\\\\=\dfrac{7x}{20}[/tex]

Hence, the fraction of his lotto earnings that is remaining is 7/20.

Judy spent 3 hours driving 165 miles She thinks
she can reach her final destination in 4 more hours
if she averages 65 miles per hour. What is the total
length of the trip in miles? [Hint: To find distance,
multiply rate (miles per hour) by time.]

Answers

Step-by-step explanation:

she drove already 165 miles.

she will reach her destination, if she drives 4 more hours by going 65 miles/hour.

that would mean she would travel

65×4 = 260 miles

in these 4 hours.

so, the total trip is then 165 + 260 = 425 miles.

but what I find strange is that your teacher specified how long it took her to drive the first 165 miles.

as you can see above, it would make no difference for the calculation of the total trip length in miles.

this is either an attempt to confuse us, or the message is that Judy has to achieve an average of 65 miles/hour for the whole trip, and the problem definition was just imperfectly phrased.

if that is the case, then things look a bit different, as her average speed was only 165/3 = 55 miles/hour for the first 3 hours and 165 miles.

so,

(165 + x)/(3 + 4) hours = 65/hour

(165 + x)/7 hours = 65/hour

165 + x = 65 × 7 hours / hour = 65×7 = 455 miles

x = 455 - 165 = 290 miles

she would have to go

290 miles / 4 hours = 72.5 miles/hour

for these next 4 hours (and 290 miles) to reach an overall average speed of 65 miles/hour.

and the total trip would be then

165 + 290 = 455 miles

I am not sure, which your teacher wants here.

65 miles/hour average speed just for the next 4 hours, or to speed up that much for the next 4 hours that the overall trip average is then 65 miles/hour.

again, the phrasing of the problem definition suggests the first case, but the fact that the travel time for the first part of the trip is given could suggest the second case (as this information is not needed for the first case).

do the lengths 30.1, 0.8, 31 make a triangle & why

Answers

Step-by-step explanation:

If this were to make a triangle, then 30.1 and 0.8 would be the shorter sides and 31 would be the longest side.

The sum of the lengths of the shorter sides is 30.1+0

8=30.9.

Since this is less than the length of the segment that would be the longest side, by the triangle inequality theorem, these side lengths would not make a triangle.

How many pairs of shoes do teenagers have? To find out, a group of AP ® Statistics students conducted a survey. They selected a random sample of 20 female students and a separate random sample of 20 male students from their school. Then they recorded the number of pairs of shoes that each student reported having. The data is given in the table.

Let 1 the true mean number of pairs of shoes that male students at the school have and 2 the true mean number of pairs of shoes that female students at the school have.

Answers

The pairs of shoes is an illustration of the point estimate of the population mean.

The teenagers have 30 pairs of shoes

How to determine the number of pair of shoes?

The question is incomplete, as the dataset to determine the number of shoes is not given.

To answer the question, I will use the following dataset

50 26 26 31 57 19 24 22 23 38 13 50 13 34 23 30 49 13 15 51

The sample mean is an estimate of the population mean.

The sample mean is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

[tex]\bar x = \frac{50 +26+ 26+ 31+ 57 +19 +24 +22+ 23 +38 +13 +50 +13 +34+ 23+ 30 +49 +13 +15+ 51}{20}[/tex]

Evaluate the sum

[tex]\bar x = \frac{607}{20}[/tex]

Evaluate the quotient

[tex]\bar x = 30.35[/tex]

Approximate

[tex]\bar x = 30[/tex]

Using the assumed values, the teenagers have 30 pairs of shoes
