Answer:

The cost of using 18 HCF = $40.39

Step-by-step explanation:

A linear function is one that has a constant rate of change for all the values within the distribution. For a linear function, there is a constant, and that constant is known as the slope or gradient of the linear function.

Let us first calculate this constant (slope).

Let:

X₁ = 14 HCF, Y₁ = $33.79, X₂ = 27 HCF, Y₂ = $55.24, m = slope

[tex]m = \frac{Y_2-Y_1}{X_2 - X_1} \\m = \frac{55.24 - 33.79}{27-14} \\m = \frac{21.45}{13} \\m = 1.65[/tex]

at any two points on the linear function, the rate of change of the cost to HCF = 1.65

Now, Let X₃ = 18 HCF, Y₃ = cost for using 18 HCF

[tex]m = \frac{Y_3 - Y_1}{X_3-X_1} \\where\ m= 1.65\\1.65 = \frac{Y_3-33.79}{18-14}\\1.65 = \frac{Y_3 - 33.79}{4} \\6.6 = Y_3 - 33.79\\Y_3 =6.6+33.79\\Y_3 = 40.39[/tex]

Therefore, the cost of using 18 HCF = $40.39

N:B X₂ and Y₂ can also be used with X₃ and Y₃ to find Y₃. You can try it out, you should get the same result

Answer:

Step-by-step explanation:

Even though no answer choices are given, the main benefit of this is that by choosing a randomly from a population it allows every single individual to have the same chance of getting chosen and observed. This randomness allows for that sample group to much more accurately represent the entire population that is being observed without having to conduct additional research. Therefore, becoming extremely useful in such studies.

A sample is a  group that is taken out of the population to be tested.

A random sampling occurs when subjects are being selected for a study  

The benefit of using random sampling is that each subject in the population is equally likely to be selected and the resulting sample is likely representative of the population.

Random sampling allows for unbiased estimates to be created, but at the cost of efficiency within the research process

Some advantages of random sampling shown below,

Step-by-step explanation:

up 3 over 4

Answer:

the correct answer is isosceles

Answer:

When two shapes are similar, their corresponding angles will be the same.  The angles are the same because the shape is still the same.  You can tell from the order of the similarity statement which angles match up.  In the example, angles A and D are the same (both letters are in written first), angles B and E are the same (both letters are written in the middle), and C and F are the same

Step-by-step explanation:

Similar triangles can be different sizes, so the lengths of the corresponding sides are not necessarily the same, but they are proportional.  This means that the ratios of the corresponding sides are equal.

Answer:

[tex]-7x^{2} -3x-2[/tex]

Step-by-step explanation:

[tex](-2x^2-5x-7) - (5x^2-2x-5)\\\\-2x^2 - 5x^2 = -7 x^2\\-5x - -2x = -3x\\-7 - -5 = -2 \\Result: -7x^2-3x-2[/tex]

Answer:

-7x² -3x - 2

Step-by-step explanation:

(-2x²-5x -7) - (5x² - 2x - 5)

removing parentheses

-2x² -5x - 7 -5x² + 2x + 5

collect like terms

-2x² - 5x² -5x + 2x -7 + 5

= -7x² -3x - 2

Answer:

slope = -3

x-intercept = (4/3,0) = (1.33,0)

y-intercept = (0,4)

f(-1) = 7

Step-by-step explanation:

Take 2 known points

i.e (0,4) and (1,1) from the graph

slope = (1-4)/(1-0) = -3

now we have

linear equation

y = mx+c

we have (0,4)

4 = -3 * 0 + C

C =4

so the equation of line is

y = -3x + 4

now

f(-1) = -3 * -1 +4 = 3+4 =7

for x intercept, put y = 0

o = -3x + 4

x = -4/-3 = 4/3

for y intercept, x = 0

y = -3 * 0 + 4 = 0+4 = 4

Answer:

x < 3

Step-by-step explanation:

5(3 - x) < -2x + 6

Distribute;

15 - 5x < -2x + 6

Add 2x to both sides;

15 - 3x < 6

Subtract 15 from both sides;

-3x < -9

Divide both sides by -3

x < 3

Answer:

70/4

= 17.5

We know 17.5 is 1% of the people that read newspaper, we will multiply 17.5 by 100 as it would represent 100% of the people

17.5 * 100

= 1750

Answer:

dh/dt = 8/9π

Step-by-step explanation:

Given that

Volume of A cone = 1/3πr²h.

Assuming v is the volume of the tank, then dv/dt = 2 m³/min

Assuming h is the height of the water we're looking for dh/dt

To start, we need to find a relationship between dh/dt and dv/dt

We then write v as a function of h, instead of having it as h & r, and then by using similar triangles, we notice that

r/h = 2/4, essentially, r = h/2.

Now, we substitute for this r, in the formula for volume

V = 1/3πr²h

V = 1/3 * π * (h/2)² * h

V = 1/3 * π * h³/4

If we differentiate v, wrt t, we have

dv/dt = π/12 * 3h² * dh/dt

dv/dt = π/4 * h² * dh/dt

Remember that h = 3, so, substitute for h

2 = π/4 * 9 * dh/dt

8/π = 9 * dh/dt

dh/dt = 8/9π
