Plot -7 in the complex plane.

Answer:

0.357

Step-by-step explanation:

The computation of the probability of sale for the last book that the bookstore should purchase for sale to a student is shown below

Probability is

= 1 - ((Cs ) ÷ (Cs + co))

= 1 - (($225 - $105) ÷ ($117 + ($105 - $40)))

= 1 - 0.6428

= 0.357

Here Cs represent the notional loss in the case when the demand is underestimated

And Co represent the notional loss in the case when the demand is overestimated

Answer:

(b) the relationship between two quantitative variables

Step-by-step explanation:

Correlation and regression techniques can be explained as a statistical techniques which measures the degree and type of relationship that exists between two variables (dependent and independent). These evaluated variables must be quantitative in nature in other to apply thus statistical method of establishing relationship and making predictive analysis. The relationship may be univariate or multivariate in nature. The correlation and regression technique won't work on data presented or represented in categorical or labeled format. The relationship may be positive or negative with the correlation Coefficient measuring the strength of the relationship between the variables.

Answer: slope= -6.0/2.0= -3.0

Step-by-step explanation:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -10.000 and for x=2.000, the value of y is -16.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -16.000 - (-10.000) = -6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

x-intercept = -10/3 = -3.33333

 y-intercept = -10/1 = -10.00000

Answer:

y+x = 5

Step-by-step explanation:

Given the equation y = x + 14

Get the slope first

The slope m = 1

Since the required equation is perpendicular to the line, the required slope will be M = -1/1 = -1

Get the required equation using the equation y-y0 = m(x-x0)

(x0, y0) = (-3, 8)

y - 8 = -1(x-(-3))

y-8 = -(x+3)

y-8 = -x-3

y+x = -3+8

y+x = 5

Hence the required equation of the line is y+x = 5

Answer:

395,500

Step-by-step explanation:

The computation is shown below:

Supplier to retailer = 320,000

Vat tax = 13%

Retailer spent for transportation = 10,000

local tax = 5,000

Profit = 15,000

Now based on the above information

the customer would pay the amount with 13% vat is

= (320,000 + 10,000 + 5,000 + 15,000) + 13% of total

= 350,000 + 13% of 350,000

= 350,000 + 45,500

= 395,500

Answer:

Answer:

2/-3

Step-by-step explanation:

It's forming an A. P. because each succeeding Te rm increases by a common value i. e. 6 here.

The A. P is

22,28,34,.....

So the n th term will be represented as

a+(n-1)d,

where a=22

And d=6

Now in (b) part the n th term is given i. e. 100

So by putting in the given values we could easily found the value of n

n=(100-22)/6=78/6=13

So the 13th term will be 100

Answer:

B. [tex]\sqrt{290}[/tex]

Step-by-step explanation:

On Edge, just finished the test.

The correct answer is option B which is the norm of the vector v is √290.

The quantity that needs both the direction and the magnitude for their representation is called a vector.

The norm of vector v will be calculated as:-

Let v be a vector with an initial point (–5, –11) and terminal point (6, 2).

Norm = [tex]\sqrt{(6-(-5))^2+( 2-(-11))^2[/tex]

Norm = [tex]\sqrt{121 + 169\\[/tex]

Norm = [tex]\sqrt { 290[/tex]

Therefore the correct answer is option B which is the norm of the vector v is √290.

Answer: it only included professional golfers

Step-by-step explanation:

It said it was right

The company's claim is incorrect. Only professional golfers took part.

The Head Golf Professional is responsible for continuously developing and implementing all service standards through careful hiring and employee training. Furthermore, he or she is in charge of maximizing income in all aspects of the golf operation while staying within the allocated budget.

There's a lot more to being a professional golfer than meets the eye. For example, did you know that their hourly wage is $18.81 on average? That works out to $39,134 per year! Between 2018 and 2028, the career is expected to grow 11%, resulting in 30,500 job openings nationwide.

To be certified as a professional golfer by the PGA, you must either have a bachelor's degree in a related discipline, such as professional golf management, or have completed the PGA professional golf management apprenticeship program.

Step-by-step explanation:

Because 500 times 30 equals 1,500

Answer:

Option A. 0.6 is the right answer.

Step-by-step explanation:

Given information is:

Mean = $240

SD = $60

The probability of Dan making less than $255 has to be found.

Let x = 255

First of all, we will find the z-score of the given value

[tex]z = \frac{x-mean}{SD}\\z = \frac{255-240}{60}\\z = \frac{15}{60}\\z = 0.25[/tex]

Now the z-score table will be used to see the probability of less than 0.25

Using the z-score table, we get:

P(x<0.25) = 0.5987

As the answer choices are rounded off to one decimal place, we will round off our answer to one digit after the decimal point

0.5987 => 0.6

Hence,

Option A. 0.6 is the right answer.

Understanding:

The total number of students is 40. 8.20% of them were absent, which means the rest were present, or in other words, (100-8.20)% were present or 91.8%. We can find the actual number of present students by multiplying the percentage of present students by the total number of students.

Solution:

Present Percentage = 91.8% or [tex]\frac{91.8}{100}[/tex]

Present Students = [tex](\frac{91.8}{100})(40)=36.72[/tex], since we are dealing with people we have to round it, so the present students are actually 37.

Step-by-step explanation:

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

Explanation:

For a conditional to be false, the antecedent must be true and the conclusion must be false. So the format is (true) --> (false) for the overall conditional to be false.

Since the antecedent must be true, this means p = true. We can shorten this to say p = T, where T stands for "true".

Now we must make (q v ~r) be false.

This is only possible if both pieces q and ~r are false. An "or" statement, aka disjunction, is true if either piece is true; otherwise it's false.

So q = F, where F stands for "false" and ~r = F as well.

If ~r = F, then r = T. Recall the squiggly line or tilde is basically the negation operator. It does the opposite of the statement.

The graph is missing, so i have attached it.

Answer:

From 0 hours to 2 hours.

Step-by-step explanation:

From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.

Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.

After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.

Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.

Step-by-step explanation:

Answer:

(0.9036, 0.9064)

Step-by-step explanation:

Given that:

True mean (m) = 0.9050

Standard deviation (s) = 0.0100

Sample size ( n) = 48

Interval for 90% of the sample mean :

Mean ± Error

Error = Zcritical * (standard deviation /sqrt(n))

Zcritical at 90% confidence interval = 1.64

Hence,

Error = 1.64 * (0.0100/sqrt(48)) = 0.0014433

Lower boundary = m - Error = (0.9050 - 0.0014433) = 0.9035567

Upper boundary = m + Error = (0.9050 + 0.0014433) = 0.9064433

(0.9036, 0.9064)
