Answer:
x and y are not in a proportional relationship
Step-by-step explanation:
x and y can be said to be in a proportional relationship, if the ratio of each given pair of values (y/x) on the table are equal. The ratio would represent the constant of proportionality.
Let's find out:
(3, 7) = y/x = 7/3 = 2.33
(6, 13) = y/x = 13/6 = 2.17
(9, 19) = y/x = 19/9 = 2.11
(12, 25) = y/x = 25/12 = 2.08
The ratio of each given pair of values are not the same. Therefore, x and y are not in a proportional relationship.

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.
What is a vector?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.

About how much does one vitamin cost?
$1.85
$0.37
$0.92
$0.04
$0.02
Answer:
Step-by-step explanation:
The approximate cost of one vitamin is $0.04 thus option (A) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given number of pills and cost.
The cost per pill from the first raw = $2.05/50 = $0.041
The cost per pill from the second raw = $4.10/100 = $0.041
The cost per pill remains constant in all so this is a direct proportion.
Hence "The approximate cost of one vitamin is $0.04".

P partitions GR in ratio 2:4. GR is 36cm. How long is GP and PR?
Answer:
12 cm and 24 cm
Step-by-step explanation:
The line is divided in the ratio 2 : 4 = 2x : 4x ( x is a multiplier )
The sum is therefore
2x + 4x = 36
6x = 36 ( divide both sides by 6 )
x = 6
Thus
GP = 2x = 2 × 6 = 12 cm
PR = 4x = 4 × 6 = 24 cm

A rectangular swimming pool is 6 ft deep. One side of the pool is 2.5 times longer than the other. The amount of water needed to fill the swimming pool is 2940 cubic feet. Find the dimensions of the pool.
The smaller dimension of the pool is __ ft.
The larger dimension of the pool is __ ft.
Answer:
The smaller dimension of the pool is 14 ft.
The larger dimension of the pool is 35 ft.
Step-by-step explanation:
We are told that:
The rectangular swimming pool is 6 ft deep. Thus, depth: h = 6 ft
One side of the pool is 2.5 times longer than the other.
Thus, length = 2.5(width)
l = 2.5w and width = w
Volume; V = lwh = (2.5w × w × 6) = 15w²
The amount of water needed to fill the swimming pool is 2940 cubic feet.
Thus;
15w² = 2940
w² = 2940/15
w² = 196
w = √196
w = 14 ft
Length: L = 2.5w = 2.5 × 14 = 35 ft
If 20 assemblers can complete a certain job in 6 hours, how long will the same job take if the number of assemblers is cut back to 12?
Given,
Total number of assemblers = 20
They work a job in 6 hours.
To find,
Time to complete the work if the number of assemblers is cut back to 12.
Solution,
Initially,
20 assemblers = 6 hours
1 hour = [tex]\dfrac{20}{6}[/tex] assemblers
If assemblers are 12 then,
[tex]t=\dfrac{20}{6}\times 12\\\\=40[/tex]
Hence, 40 hours will be required if the number of assemblers is cut back to 12.

Lateral Area = No lateral area (choice D)Surface Area = 25.97 square inches (choice E)Volume = 12.44 cubic inches (choice A)============================================
Explanation:
Lateral area only applies to prisms and cylinders. Spheres do not have lateral sides, so there is no lateral area.
-----------------------
The radius is 1 & 7/16
Let's convert this to decimal form
1 & 7/16 = 1 + (7/16)
1 & 7/16 = 1 + 0.4375
1 & 7/16 = 1.4375
The radius is r = 1.4375 inches.
-----------------------
SA = Surface area the sphere
SA = 4*pi*r^2
SA = 4*pi*(1.4375)^2
SA = 25.9672267773281
SA = 25.97 square inches (choice E)
-----------------------
V = Volume of the sphere
V = (4/3)*pi*r^3
V = (4/3)*pi*(1.4375)^3
V = 12.4426294974698
V = 12.44 cubic inches (choice A)

On a coordinate plane, a point is 0.5 units to the left and 1.5 units up. Another point is 0.5 units to the right and 1.5 units down. On a coordinate plane, a point is 1.5 units to the left and 0.5 units down. Another point is 1.5 units to the right and 0.5 units up.
Answer:
Graph 'B' represents the correct graph.
The correct graph is attached below.
Step-by-step explanation:
Let 'A' be the point:
[tex]A\left(-1\frac{1}{2},\:\frac{1}{2}\right)[/tex]Let 'B' be the point:
[tex]B\:\left(1.5,\:-0.5\right)[/tex]As point A(-1 1/2, 1/2) can be written as:
[tex]A=\left(-\frac{3}{2},\:\frac{1}{2}\right)=\left(-1.5,\:0.5\right)[/tex]
so plotting the point [tex]A=\left(-1.5,\:0.5\right)\:\:\:\:[/tex] and [tex]B\:\left(1.5,\:-0.5\right)[/tex] on a [tex]B\:\left(1.5,\:-0.5\right)[/tex].
As we know that the 2nd quadrant, in the upper left-hand corner, consists of negative values of x and positive values of y.Thus, the point A(-1.5, 0.5) will be plotted in the 2nd quadrant at x = -1.5 and y=0.5
i.e. at x= -1.5, y = 0.5
As we know that the 4th quadrant, the lower left-hand corner, consists of positive values of x and negative values of y.Point B(1.5, -0.5) will be plotted in the 4th quadrant at x = 1.5 and y = -0.5
i.e. at x= 1.5, y = -0.5

The hose on a power washer is 42-ft. long. If the compressor to which the house is attached is located at the corner of a 28-ft wide house, how can the hose reach up the far corner without moving the compressor?
a. What is the exact height that the hose can reach up?
b. What is the approximate height that the hose can reach up?
9514 1404 393
Answer:
a) 14√5 feet
b) about 31.3 feet
Step-by-step explanation:
a) The 42-ft hose is the hypotenuse of a right triangle with one leg 28 ft. We are asked to find the other leg. The Pythagorean theorem is useful.
h² +(28 ft)² = (42 ft)²
h² = (1764 -784) ft² = 980 ft²
h = √(196·5) ft
h = 14√5 ft
__
b) The approximate height is ...
14√5 ≈ 31.305, about 31.3 feet

A consumer group wants to know if an automobile insurance company with thousands of customers has an average insurance payout for all their customers that is greater than $500 per insurance claim. They know that most customers have zero payouts and a few have substantial payouts. The consumer group collects a random sample of 18 customers and computes a mean payout per claim of $579.80 with a standard deviation of $751.30. Is it appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers
It isn't appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.
The major reason is because the sample is short and it is given that most consumer has zero payouts.
What do we know?Most customers have zero payouts and a few have substantial payoutsSample size = 18Sample mean = $579.80Sample variance = $751.30How to know if it is appropriate to perform hypothesis testing?The size of the sample taken is not enough large. When sample isn't large enough, it represents skewed information of the population.
The population itself contains many customers who have zero payouts, thus the population isn't normally distributed for insurance claim.
Because of these reasons, the sample mean won't help in deducing conclusions about population mean.
Thus, it is inappropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.

It is not appropriate to perform a hypothesis test for the mean payout of all customers, mostly because the sample is really small.
What do we know?Most customers have zero payouts and a few have substantial payouts Sample size = 18 Sample mean = $579.80 Sample variance = $751.30What does this imply?
The first thing you can see is the sample size, it seems to be really small for a company with thousands of customers, is really probably that just 18 of them do not represent accurately the whole population.
We also do know that a large proportion of the population has zero payouts, so the population is skewed.
Just because of these two motives, the mean of the sample most likely does not accurately portray the whole population, thus is not appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.
