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.

Step-by-step explanation:

The equations could be used to predict the value is

V(t) = 1000 (1+ 5/100[tex])^t[/tex]

A financial concept known as future value (FV) assigns a value to an asset based on anticipated factors like future interest rates or cashflows. Knowing how much their investment would be in five years, given a projected rate of return, may be valuable for an investor.

We have,

P= $1000

R= 5%

T= time in years

We know that amount

A(t) = P(1 + R/100[tex])^t[/tex]

So, V(t) = 1000 (1+ 5/100[tex])^t[/tex]

Thus, the required function is  V(t) = 1000 (1+ 0.05[tex])^t[/tex]

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

Answer:

95%

Step-by-step explanation:

%Change from 800 to 40 = %Decrease

%Decrease = Old Value - New Value/Old Value × 100%

%Decrease = 760/800 × 100%

% Decrease = 95%(Answer)

Answer:

Step-by-step explanation:

The approximate cost of one vitamin is $0.04 thus option (A) is correct.

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".

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​.

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.

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.

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.

Answer:

  see below

Step-by-step explanation:

We assume your functions are ...

  f(x) = x²

  g(x) = (x -4)² +12

_____

You need to be able to recognize that g(x) matches a pattern:

  g(x) = f(x-h) +k

where h = 4, and k = 12.

In this pattern, the value of h is the number of units the graph is translated to the right. The value of k is the number of units the graph is translated up.

So, g(x) is the same as the graph of f(x), but translated 4 units right and 12 units up.

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

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]

The radius is 1 & 7/16

Let's convert this to decimal form

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
