Answer:
Units of hair products = 2634 units
Step-by-step explanation:
Given that:
Worth of products in the inventory = $6400
Average cost per unit = $2.43
Number of units = [tex]\frac{Total\ worth}{Per\ unit\ cost}[/tex]
Number of units = [tex]\frac{6400}{2.43}[/tex]
Number of units = 2633.73
Rounding off to nearest whole number = 2634 units
Hence,
Units of hair products = 2634 units

The tourism industry hires a marketing company to promote overseas vacations. The marketing companies research shows a +0.72 correlation between the number of overseas vacations booked and amount of free time, in days, people have each year. Therefore, the marketing company decides to develop an advertising campaign aimed specifically at people, who have lots of free time.
Which of the following is true about this decision?
a. The decision may not be a good one, since it is possible that there is a "lurking" variable, such as income, behind both the number of booked overseas vacations and the number of free days people have each year.
b. The decision is a good one, since we know that the number of free days people have cause them to book more vacations.
c. The decision is a good one, since there is a strong positive relationship between number of booked vacations and the number of free days people have each year.
d. The decision is may not be a good one, since there is a strong positive relationship between number of booked vacations and the number of free days people have each year.
Answer:
A: The decision may not be a good one, since it is possible that there is a "lurking" variable, such as income, behind both the number of booked overseas vacations and the number of free days people have each year.
Step-by-step explanation:
The correlation coefficient given alone is not sufficient to find out whether the relationship was linear or not. As such there may be a lurking variable and we may therefore have to see the scatter plot diagram to help us know if the relationship was a linear one or not.

integration of dx/3sin^2 -4
Answer:
= 1/2 tan^(-1)(2 cot(x)) + constant
Step-by-step explanation:
Take the integral:
integral1/(3 sin^2(x) - 4) dx
Multiply numerator and denominator of 1/(3 sin^2(x) - 4) by -sec^2(x):
= integral-(sec^2(x))/(4 sec^2(x) - 3 tan^2(x)) dx
Prepare to substitute u = tan(x). Rewrite -(sec^2(x))/(4 sec^2(x) - 3 tan^2(x)) using sec^2(x) = tan^2(x) + 1:
= integral-(sec^2(x))/(tan^2(x) + 4) dx
For the integrand -(sec^2(x))/(tan^2(x) + 4), substitute u = tan(x) and du = sec^2(x) dx:
= integral-1/(u^2 + 4) du
Factor out constants:
= - integral1/(u^2 + 4) du
Factor 4 from the denominator:
= - integral1/(4 (u^2/4 + 1)) du
Factor out constants:
= -1/4 integral1/(u^2/4 + 1) du
For the integrand 1/(u^2/4 + 1), substitute s = u/2 and ds = 1/2 du:
= -1/2 integral1/(s^2 + 1) ds
The integral of 1/(s^2 + 1) is tan^(-1)(s):
= -1/2 tan^(-1)(s) + constant
Substitute back for s = u/2:
= -1/2 tan^(-1)(u/2) + constant
Substitute back for u = tan(x):
= -1/2 tan^(-1)(tan(x)/2) + constant
Which is equivalent for restricted x values to:
Answer: = 1/2 tan^(-1)(2 cot(x)) + constant
Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of about 28,000 per day. In December 2005 the Las Vegas Monorail Company raised the fare to $5 per ride, and average ridership in 2006 plunged to around 19,000 per day.
a. Use the given information to find a linear demand equation.
b. Find the price the company should have charged to maximize revenue from ridership. What is the corresponding daily revenue?
c. The Las Vegas Monorail Company would have needed $44.9 million in revenues from ridership to break even in 2006. Would it have been possible to break even in 2006 by charging a suitable price?
Answer:
A)The required linear demand equation ( q ) = -4500p + 41500
B) $4.61
$95680.55
C) No it would not have been possible by charging a suitable price
Step-by-step explanation:
A) find the linear demand equation
given two points ; ( 3, 28000 ) and ( 5, 19000 )
slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )
= ( 19000 - 28000 ) / ( 5 - 3 ) = -4500
slope intercept is represented as ; y = mx + b
where y( 28000) = -4500(3) + b
hence b = 41500
hence ; y = -4500x + 41500
The required linear demand equation ( q ) = -4500p + 41500 ----- ( 1 )
p = price per ride
B ) Determine the price the company should charge to maximize revenue from ridership and corresponding daily revenue
Total revenue ( R ) = qp
= p ( -4500p + 41500 )
hence R = -4500p^2 + 41500p ------ ( 2 )
To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p to a quadratic equation R(p) = ap^2 + bp + c
where a = -4500 , b = 41500 , c = 0
hence p = [tex]-\frac{b}{2a}[/tex] = [tex]- \frac{41500}{2(-4500)}[/tex] = 4.61
$4.61 is the price the company should charge to maximize revenue from ridership
corresponding daily revenue = R = -4500p^2 + 41500 p
where p = $4.61
hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55
C) No it would not have been possible by charging a suitable price

Can you make a triangle with lengths 10,7,15
Answer:
yes
Step-by-step explanation:
Answer:
The formation of ∆ is possible .
Step-by-step explanation:
Three sides of triangle are given which are 10 , 7 & 15. And we need to determine whetherwecanmake a triangle with these three sides or not . So we know that ,
" Sum of any two sides of a triangle is Greater
than the third side "
Let ,
a = 10b = 7c = 15Here we will see by three cases. And the formation of triangle will be possible if and only of all the three cases are possible.
So , let's check ,
Case 1:-
→ a + b > c
→ 10 + 7 > 15
→ 17 > 15
Case 2:-
→ b + c > a
→ 7 + 15 > 10
→ 22 > 10
Case 3 :-
→ a + c > b
→ 10 + 15 > 7
→ 25 > 7
Since all the three cases are true Hence formation of ∆ is possible.
Hence the formation of triangle is possible .x + 2 + (1.5x -6) =16 what is X

1 tsp of water = 1/3 tsp of salt
1 tsp of water = 0.33 tsp of salt ____(1)
Mika adds 4 tsp of salt to 9 tsp of water.
9 tsp of water = 4 tsp of salt
Divide both sides by 9.
1 tsp of water = 4/9 tsp of salt
1 tsp of water = 0.0092 tsp of salt ____(2)
From (1) and (2) we see that,
Jack's water is saltier.

Answer:
∠U = 31°
Step-by-step explanation:
∠W has an exterior angle next to it, making them supplementary angles. This means they equal 180° together. First, we solve for ∠W:
∠W + 84 = 180
∠W = 96
We know that ∠W is 96°.
We know that the sum of the angles of a triangle is 180°. Knowing that we can solve for ∠U:
96 + 53 + ∠U = 180
149 + ∠U = 180
∠U = 31
Therefore, ∠U = 31°

A local catering company ordered 15 pounds of chicken, 21 pounds of beef, and 7 pounds of lobster. The cost of the chicken was $2 per pound, the cost of the beef was $4 per pound, and the cost of the lobster was $12 per pound. What was the total cost of the order?
the total price of the catering company's order was $198.
To discover the total value of the order, we need to multiply the kilos of every type of meat via its respective cost in keeping with pound and then add those products together.
For the chook:
15 pounds x $2 per pound = $30
For the beef:
21 kilos x $4 per pound = $84
For the lobster:
7 pounds x $12 per pound = $84
Now, we add up the costs of each form of meat to find the total cost of the order:
$30 + $84 + $84 = $198
Consequently, the whole price of the catering company's order was $198.

his third an 92. What must he score on his fourth exam to get an A (90%) in the course?
98
b. 90
C. 88
d. 86
a.
Please select the best answer from the choices provided
А A
D
Answer:
The answer is A) 98.
Step-by-step explanation:
Rex has to score 98 marks in his fourth exam to obtain a grade A in the course.
Calculations for the score in the fourth exam:Total marks in four exams = 100 + 100 + 100 + 100 = 400
Marks required for an A (90%) in four exams = 90% of 400
= [tex]\frac{90}{100}\times 400[/tex]
= 360
Rex scores in Ist, 2nd and 3rd exam = 84, 86 and 92
So the score to be obtained in 4th exam for an A = 360 - (84 + 86 + 92)
= 98
Therefore, Rex has to score 98 marks in 4th exam to get a grade A.
