Answer:

15

Step-by-step explanation:

The constant of proportionality is 15 books per shelf.

If you look at the graph, you can see that for every 1 shelf, there are 15 books. For 1 shelf, there are 15 books, and for 2 shelves, there are 30. And the pattern continues.

Answer:

A = 29/51   B = 22/51

Step-by-step explanation:

(E) =  number of favorable outcomes/ total number of possible outcomes

- number of possible outcomes= 51

- number of favorable outcomes= 29

therefore, P(E) = 29/51

- number of possible outcomes= 51

- number of favourable outcomes = 51 - 29 = 22

therefore, P(E)= 22/51

Answer:

The first option

Step-by-step explanation:

The first option:

f(x) = 4(x^2)

Each time x is squared and then multiplied by 4.

___

f(1) = 4(1^2) = 4

f(2) = 4(2^2) = 16

f(3) = 4(3^2) = 36

f(4) = 4(4^2) = 64

Answer:

The first one

Step-by-step explanation:

This is because the function of it is f(x) =  4x^2. Additionally, this can be seen as there is not a perfect difference between the values.

Answer:

The correct option is C. (x=2)

Step-by-step explanation:

Given

Length of the hypotenuse of the right angled triangle (h) = 2.5 cm

Length of one of the side (a) = 1.5 cm

Let the length third side be 'b' cm

By Pythagoras theorem

h² = a² + b²

Adding Values on both sides

⇒ (2.5)² = (1.5)² + b²

⇒ 6.25 = 2.25 + b²

⇒ 6.25 - 2.25 = b²

⇒ 4 = b²

⇒ √4 = b

⇒ 2 = b

⇒ b = 2

From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;

- Yes, the sampling method is biased.

- The likely direction of the bias is because you only asked 5 people which

is  not a significant percentage of those offering psychology majors and as

such the 4 out of 5 gotten is likely going to be an over estimation of those

who are willing to pay to join this club.

We are told that;

Therefore, this would lead to sampling bias and thus the sample is biased.

Answer:

Step-by-step explanation:

The perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

The coordinates are given as:

(−4,4), (−4,1), and (−8,−4).

Calculate the distance between the vertices using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]

So, we have:

[tex]AB = \sqrt{(-4 + 4)^2 + (4-1)^2} = 3[/tex]

[tex]BC = \sqrt{(-4 + 8)^2 + (1+4)^2} = \sqrt{41[/tex]

[tex]AC = \sqrt{(-4 + 8)^2 + (4+4)^2} = \sqrt{80[/tex]

The perimeter is the sum of the side lengths.

So, we have:

[tex]P = 3 + \sqrt{41} + \sqrt{80}[/tex]

Expand

[tex]P = 3 + \sqrt{41} + 4\sqrt{5}[/tex]

Hence, the perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

Step-by-step explanation:

Use the compound interest formula and substitute the values given:

$250,000=P(1+0.0412)12(15)

Simplify using order of operations:

$250,000=P(301/300)180

Answer:

Victor has 18 trophies

Step-by-step explanation:

Let's set up "let statements"

Let d = Dean's trophies

Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...

Let 2d = Victor's trophies

Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...

2d + d = 27

Combine like terms...(2d and d)

3d = 27

Divide 3 on both sides to isolate the variable "d"

3d ÷ 3 = d

27 ÷ 3 = 9

So...

d = 9

That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...

2 · 9 = 18

Therefore, Victor has 18 trophies!

Hope this helps :)

Distance is the number of units between points.

The distance that are 7 units from 4 are: 11 and -3

A distance of 7 units from 4 means:

[tex]x - 7 = 4[/tex]  or [tex]x + 7 =4[/tex]

Where:

x is the required distance

Solve for x in both equations.

[tex]x - 7 = 4[/tex]

[tex]x = 7 + 4[/tex]

[tex]x = 11[/tex]

[tex]x + 7 =4[/tex]

[tex]x =4 - 7[/tex]

[tex]x =- 3[/tex]

So, the distance that are 7 units from 4 are: 11 and -3
