Answer:

(a) [tex]y = 4.5x + 22[/tex] -- The equation

(b) 31 inches

Step-by-step explanation:

Given

See attachment

Solving (a): The equation of the trend line.

We start  by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (0,22)[/tex]

[tex](x_2,y_2) = (4,40)[/tex]

So, we have:

[tex]m = \frac{40 - 22}{4 - 0}[/tex]

[tex]m = \frac{18}{4}[/tex]

[tex]m = 4.5[/tex]

The equation is then calculated using:

[tex]y = m(x-x_1)+y_1[/tex]

Where:

[tex](x_1,y_1) = (0,22)[/tex]

[tex]m = 4.5[/tex]

[tex]y = 4.5(x - 0) + 22[/tex]

Open bracket

[tex]y = 4.5x - 0 + 22[/tex]

[tex]y = 4.5x + 22[/tex]

(b) The height of a 2 year old.

To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]

[tex]y = 4.5 * 2 + 22[/tex]

[tex]y = 9+ 22[/tex]

[tex]y = 31[/tex]

The prediction is 31 inches

Answer:

$3.40 per card

Step-by-step explanation:

To find the unit rate, divide the total cost ($17) by the number of cards (5 cards):

 $17

--------------- = $3.40 per card

   5 cards

Answer: $3.4

Step-by-step explanation: If 5 cards cost $17

Divide 17 by 5 : 17/5

Your result will be 3.4

Meaning 1 card cost $3.4

Answer:

x=20

x=21

x=22

x=23

x=24

Step-by-step explanation:

We are given that

[tex]19<r[/tex]

[tex]r<25[/tex]

We have to find value of x which is a solution to both of the given inequalities.

First we find the solution of given inequalities

[tex]19<r<25[/tex]

The value of r lies between 19 and 25.

Therefore, the possible values of r are

20,21,22,23,24

Hence, the value of x which is the solution of both given inequalities is given by

x=20

x=21

x=22

x=23

x=24

From the given triangles RST and TXY, angle R is equal to angle XTY. Therefore, option B is the correct answer.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Given that, ΔRST≅ΔTXY.

We know that, corresponding parts of congruent triangle are equal

Here, ∠R=∠XTY

Therefore, option B is the correct answer.

Step-by-step explanation:

Area of a rectangle is length multiplied by width. So 2/3 times 1/2 which equals 1/3 or .33333 repeated

Answer:

B. 1/3.

Step-by-step explanation:

The area of a rectangle is represented by the following equation:

Area = width x height

In this case it would look like this:

[tex]Area = \frac{1}{2} * \frac{2}{3}[/tex]

Now, we solve:

[tex]Area = \frac{2}{6} \\Area = \frac{1}{3}[/tex]

Therefore, the correct answer is B. 1/3.

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

[tex]P=4000\times 2^d[/tex]

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

[tex]P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000[/tex]

So, if d = -2, then the population of the suburb is equal to 1000.

Answer:

x = 5.26 m

Step-by-step explanation:

Given that,

The angle of inclination = 20°

The vertical height of the ramp, h = 1.8 m

We need to find the length of the ramp. Let it is x.

We can find it using trigonometry. So,

[tex]\sin\theta=\dfrac{P}{H}[/tex]

We have,

P = 1.8 m, H = x

[tex]\sin20=\dfrac{1.8}{x}\\\\x=\dfrac{1.8}{\sin20}\\\\x=5.26\ m[/tex]

So, the length of the ramp is 5.26 m.
