Answer:

a) The DSO decreases.

Step-by-step explanation:

DSO is short for Days Sales Outstanding and it is a measure of how quickly a company can convert its accounts receivable to cash. A company is described as strong when it has enough cash flow and this can be achieved by reducing the length of days within which accounts receivable can be converted to cash.

For the company to achieve a lowered DSO, it must ensure that customers with bad or low credit ratings are not allowed, or reasonably reduced in the business. The accounting and payment procedures must also be checked to be expedient so that delays in payment procedures would be reasonably reduced.

Answer:

(B) 0.708

Step-by-step explanation:

The table, representing details of this information and all that are necessary to calculate the linear correlation coefficient r, has been attached to this response.

With all details well represented on the table, we can now find the linear correlation coefficient r using the relation attached to this response:

From the relation;

n = sample size = 8

∑xy = 3347

∑x = 44

∑y = 569

∑x² = 320

∑y² = 41681

Substitute these values into the relation as follows;

[tex]r = \frac{3347 - \frac{44* 569}{8} }{\sqrt{(320 - \frac{44^2}{8} )(41681 - \frac{569^2}{8} ) } }[/tex]

[tex]r = \frac{217.50}{307.32}\\[/tex]

r = 0.7077

r = 0.708 to 3 decimal places

Therefore, the value of the linear correlation coefficient is 0.708

Answer:  15  dimes

Step-by-step explanation:

Nickels are 5 cents and dimes are 10 cents  and since they are a total of 1.95 coins in total we can set up the two equations and solve for how much there are for each of the money.

x + y = 24  

0.05x + 0.10y = 1.95   so solve for  y  and  x is the number of nickels while y is the number of dimes.

x+y=24

   -y    -y

x = -1y +24  

0.05(-1y +24) + 0.10y = 1.95

 -0.05y + 1.2 + 0.10y = 1.95

       0.05y + 1.2 = 1.95

                     -1.2   -1.2

          0.05y = 0.75

   y = 15

[tex]\[\begin{array}{l} - 6x + 3y = 3\\y = 2x + 1\\f(x) = 2x + b\\f(5) = 4\\4 = 2 \cdot 5 + b\\ - 6 = b\\f(x) = 2x - 6\end{array}\]\\[/tex]

Answer:

B) y = -9.98×10⁻⁵ x + 13.95

C) 0.1

Step-by-step explanation:

Using Excel, the least squares regression line, rounded to two decimal places, is y = -9.98×10⁻⁵ x + 13.95.

The slope is -9.98×10⁻⁵, so if x increases by 1000, then y changes by -9.98×10⁻² = -0.0998.  Rounded to one decimal place, the ulcer rate per 100 population will go down by 0.1 points.

Answer:

if q is odd

Step-by-step explanation:

Hello,

Either q is odd or is even.

Case 1 - we can find k integer so that q = 2k

Then, in the case

[tex]q^2-1=4k^2-1[/tex]

This is not divisible by 8, for instance, q = 6

[tex]q^2-1=36-1=35=7*5[/tex]

Case 2 - we can find k integer so that q = 2k+1

[tex]q^2-1=(2k+1)^2-1=4k^2+4k+1-1=4k(k+1)[/tex]

k(k+1) is divisible by 2 so the initial number is divisible by 8

Conclusion, the answer is q is odd.

Answer:B

Step-by-step explanation:

B because it can be answered with yes or no while the others need more answers

Answer:

B. 95

Step-by-step explanation:

Plug in 8625 into the equation as c:

c = 75n + 1500

8625 = 75n + 1500

Solve for n:

7125 = 75n

95 = n

So, 95 people attended.

Answer:

B

Step-by-step explanation:

So we have the equation:

[tex]c=75n+1500[/tex]

Where c represents the wedding cost and n represents the number of people who attended the wedding.

We know that the wedding cost a total of $8625. Thus, we can plug this number in for c and solve for n:

[tex]8625=75n+1500[/tex]

Subtract 1500 from both sides. The right cancels:

[tex](8625)-1500=(75n+1500)-1500\\7125=75n[/tex]

Now divide both sides by 75:

[tex](7125)/75=(75n)/75\\n=95[/tex]

Thus, a total of 95 people attended the wedding.

Answer:

5

Step-by-step explanation:

Answer:

x=1/2     y=1/4

Step-by-step explanation:

Get simplify the first equation to get x alone

4y/2=2x/2

2y=x

Plug x into the second equation

2(2y)+y=(2y)/2 +1

4y+y=y+1

4y+y-y=y-y+1

4y=1

y=1/4

Now plug the y-value into one of the equations and solve for x

4(1/4)=2x

2x=1

x=1/2

Check by plugging both the x- and y-values into the other equation and solving to make sure both sides are equal

2(1/2)+(1/4)=(1/2)/2 +1

1+1/4=1/4+1

5/4=5/4

The values are correct!

Answer:

Elaine spent $50, Danetta spent $75, and Jan spent $40

Step-by-step explanation:

Let x represent how much Elaine spent:

Danetta will be represented by x + 25

Jan will be represented by x - 10

Then, create an equation:

x + x + 25 + x - 10 = 165

Add like terms and solve for x:

3x + 15 = 165

3x = 150

x = 50

So, this means Elaine spent $50

Plug in 50 as x to find how much Danetta and Jan spent:

x + 25

50 + 25

= $75 (Danetta)

x - 10

50 - 10

= $40 (Jan)

So, Elaine spent $50, Danetta spent $75, and Jan spent $40

The money spent by Danetta is $75, the money spent by Elaine is $50, and the money spent by Jan is $40.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Let D be the money spent by Danetta, E be the money spent by Elaine, and J be the money spent by Jan.

Three friends went shopping. Danetta spent $25 more than Elaine spent. Then the equation will be

D = E + 25

E = D – 25

But Jan spent $35 less than Danetta spent. Then the equation will be

J = D – 35

If they spent $165 in all. Then the equation will be

D + E + J = 165

Put the value of E and J in the above equation.

D + D – 25 + D – 35 = 165

                   3D – 60 = 165

                            3D = 225

                              D = 225 / 3

                              D = 75

Then the value of E will be

E = D – 25

E = 75 – 25

E = 50

Then the value of J will be

J = D – 35

J = 75 – 35

J = 40

(you’re using that equation because the numbers have to be equal at the end. also “x” is the variable) after that subtract 16,682 from both sides that should give you (40,959+10x= 19.25x) after that subtract 10x from both sides, that should give you (40,959 = 9.25x) Lastly divide both sides by 9.25 and you should get x=4,428.

Probability sampling is used as a sampling method in which the researcher chooses samples from a large population using a method which is based on the theory of probability. For an item to be qualify as a probability sample, that item must be selected using a random selection. An example is the selection of 2 girls from a group of 20 students where 12 are girls and 8 are boys.

Small X^2 value, large p-value

=================================================

Explanation:

The X^2 refers to chi-squared or chi-square value.

If the observed and expected values are close, then their differences are small leading to small squares of those differences. Consequently, this means the sum of the squared differences is also small leading to a small X^2 value.

The p-value is the probability of getting a certain chi-square value or larger. If X^2 is small, then we have a very large chance of getting that certain X^2 value or larger. Visually, the area under the chi-square curve to the right of X^2 will be large if X^2 is small.

A large p-value means we fail to reject the null hypothesis. You can think of the p-value as the probability that the null is correct (though because of some technical reasons it's not this entirely, but its close enough). This means a large p-value tells us to accept that the data fits the distribution we're trying to compare to.

In this exercise we have to use probability knowledge so we can say that the correct alternative is:

Answer:

y = -2/3x + 22/3

Step-by-step explanation:

An equation is written in slope-intercept form when it is written as:

y = mx + b, where m is the slope of the line and b is the y-intercept.

Therefore, because we are given m and a coordinate pair of the line, we can use the point-slope formula to make the equation.

The point-slope formula is [tex]\boxed{y-y_{1}=m(x-x_{1})}[/tex].

Because we are given only one coordinate pair, it is labeled as [tex](x_{1}, y_{1})[/tex].

Now, just plug in this information and solve the equation.

y - 4 = -2/3(x - 5) Distribute the -2/3 throughout the terms.

y - 4 = -2/3x + 10/3 Add 4 to both sides of the equation.

y = -2/3x + 22/3
