What Is The Constant Of Proportionality For The Relationship Represented By This Graph?

Answers

Answer 1

Answer: (5,11)

Step-by-step explanation:

Answer 2

Answer:

k = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of proportionality is

y = kx ← k is the constant of proportionality

To find k use any coordinate point lying on the graph

Using (12, 6 ), then

6 = 12k ( divide both sides by 12 )

k = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

Harold can buy 2 pounds of bananas for $7. Write an equation to represent the cost, c , for b bananas.

Answers

7c = 2b
If he can buy two pounds of bananas for $7 that means 2lbs is equal to $7

The equation representing the situation is c = 3.5b

What is an equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Harold can buy 2 pounds of bananas for $7.

Since, he can buy 2 pounds in $7 so, 1 pound in = 7/2 = $3.5

So, when he will buy b pounds of bananas he will spend = $3.5b

So, if c is the total cost for b pounds of bananas, then the equation representing the total cost for b pounds of bananas will be,

c = 3.5b

Hence, c = 3.5b is the equation that represent the cost, c, for b bananas.

Convert into vertex form. Give the vertex.
y = 3x² – 24x + 46

Answers

Here you go! Hope this helps!!!

Answer:

Vertex form: [tex]y = 3(x - 4)^2 - 2[/tex]

Vertex: (4, -2)

Step-by-step explanation:

Hello!

We have to complete the square, and then simplify.

Solve:[tex]y = 3x^2 - 24x + 46[/tex][tex]y = 3(x^2 - 8x) + 46[/tex]
Take the coefficient of the second term, divide it by 2, and square it.[tex]y = 3(x^2 - 8x + 16) + 46 - 3(16)[/tex]
Balance your equation by subtracting what you added. Simplify.[tex]y = 3(x - 4)^2 - 2[/tex]

The equation in vertex form is [tex]y = 3(x - 4)^2 - 2[/tex]

The vertex is (4,-2)

Vertex form

Vertex form is f(x) = a(x - h)² + k, where (h, k) is the vertex.

Consider a large population with a mean of 100 and a standard deviation of 21. A random sample of size 36 is taken from this population. The standard error of the sampling distribution of sample mean.

Answers

Answer:

3.5

Step-by-step explanation:

Given that:

Population mean (m) = 100

Standard deviation (σ) = 21

Sample size (n) = 36

The standard error of the sampling distribution of sample mean :

Standard Error is given by:

Standard deviation / sqrt(n)

Thus,

Standard Error = 21 / sqrt(36)

Standard Error = 21 / 6

Standard Error = 3.5

Answers

Answer:

80 heart stickers does a pack of 140 stickers

Step-by-step explanation:

The number of heart stickers in a pack of 140 stickers is 60.

Given that, a sheet of 28 stickers has star and heart stickers.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Here, the number of star stickers in a sheet

= 28-16 =12

The ratio of star and heart stickers

= 12:16

= 3:4

Now, 3+4=7

Number of heart stickers = 3/7 ×140

= 60

Therefore, the number of heart stickers in a pack of 140 stickers is 60.

Tickets for 2 adults and 4 children at a theme park cost £152.

An adult ticket costs twice as much as a child ticket.

Write and solve an equation to work out the price of an adult ticket​

Answers

Step-by-step explanation:

Let x be the price of an adult ticket.

Then 0.5x is the price of a child ticket.

We have 2x + 4(0.5x) = £152, therefore 4x = £152 and x = £38.

Hence the price of an adult ticket is £38.

Answer:

Step-by-step explanation:

2a+4c=152

2c=a

4c+2a=152

2c-a=0

Use simultaneous equation

Substitute 2c=a

                  c=a divided by 2 in the first equation and find value of a and c

Sasha has a 35% off coupon. Her total before tax came to $23.00. How much did the item originally cost? (round to the nearest hundreds) PLS help!! (middle school and pls show work)

Answers

Answer:

The original cost of the product was $35.68.

Step-by-step explanation:

As Sasha has a discount coupon of 35%, the final amount that he will pay is 65% of the initial value of the product (100 - 35). Thus, 65% of the value is $ 23. Therefore, to determine the initial cost of the product, it is necessary to perform the following calculation:

65 = 23

100 = X

((100 x 23) / 65) = X

2,300 / 65 = X

35.68 = X

Therefore, the initial value of the product was $ 35.68.
