What type of association is shown in the scatterplot?

Answer:

20.25

Step-by-step explanation:

21-3/4=20.25

Answer:

Step-by-step explanation:

a+b=21

a=21-b

b=3/4*a

b=3/4*(21-b)

b=3(21-b)/4

b=63-3b/4

4*b=63-3b

4b+3b=63

7b=63

b=63/7

b=9

Answer:

62 degrees

Step-by-step explanation:

Every triangle needs to have 180 degrees. Simply you have to add 60+58 which is 118 degrees. Then you subtract 180-118 which equals to 62 degrees.

Answer:

76 m²

Step-by-step explanation:

The figure has been decomposed into 3 rectangles as shown in the attachment. Therefore:

Area of the figure = area of rectangle 1 + area of rectangle 2 + area of rectangle 3

✔️Area of rectangle 1:

Area = L*W

L = 2 m

W = 4 m

Area = 2*4 = 8 m²

✔️Area of rectangle 2:

Area = L*W

L = 4 m

W = 6 - 4 = 2 m

Area = 4*2 = 8 m²

✔️Area of rectangle 3:

Area = L*W

L = 10 m

W = 6 m

Area = 10*6 = 60 m²

✅Area of the figure = 8 + 8 + 60

= 76 m²

Answer:

x = 3.75

Answer:

28°

Step-by-step explanation:

Supplementary angles sum to 180°

( dozen sixes) + 80

= 12 × 6 + 80

= 72 + 80

= 152°

supplement = 180° - 152° = 28°

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

copy the above onto your computer for future reference

sin(g) = 420/427

tan(z) = 77/420

cos(z) = 420/427

sin(m) = 427/427

part (E)   the sin of any right angle will be  1   :)

Answer:

Solution given:

Sin G=opposite/hypotenuse=420/427

TanZ=Opposite/adjacent=77/420

CosZ=adjacent/hypotenuse=420/427

Sin M=opposite/hypotenuse=427/427=1

Answer:

(6, 12)

Step-by-step explanation:

{ 3x - y = 6

{ x - 2y = -18

by using elimination:

6x -2y=12

x - 2y= -18

________-

5x = 30

x = 6

y = 18-6 = 12

the solutions = {(6, 12)}

Step-by-step explanation:

I used Pythagoras Theorem to find the diagonal distance as placement of objects is right angles triangle.

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

a : Elm street

b : Birch street

c : Diagonal distance

c^2 = a^2 + b^2

c^2 = 15^2 + 8^2

c^2 = 225 + 64

c = √289

c = 17 blocks

I added the total distance of the original route Joline took

= 15 blocks + 8 blocks

= 23 blocks

How much less distance does she have to walk if she took the diagonal route

= Total distance of original route - distance of diagonal route

= 23 - 17

= 6 blocks

Joline have to walk less 6 blocks if she took the diagonal route compared to her original route

Answer:

4) x = 19

Part B = 37

Step-by-step explanation:

These 2 angles are equal to each other because they're vertical angles.

4x + 67 = 143

4x = 143 - 67

4x = 76

x = 19

m<HIK:

180 - 143 (because it's supplementary to m<GIK)

Answer: [tex]n>14[/tex]

Step-by-step explanation:

Given

Misty needs to gather at least 20 flags for the parade

She has already gathered 6 flags

Inequality to find the number of flags needed is

[tex]n+6>20[/tex]

Subtract -6 from both sides

[tex]\Rightarrow n+6-6>20-6\\\Rightarrow n>14[/tex]

Therefore, option (j) is correct.

They have equal lengths is the correct answer

Given:

The height of the triangular prism is 15 cm.

The side lengths of the base are 3 cm, 4 cm and 5 cm.

To find:

The lateral surface area of the prism.

Solution:

The lateral surface area of the prism is:

[tex]LSA=Ph[/tex]

Where, P is the perimeter of base and h is the height of the prism.

We know that the perimeter of base is the sum of all sides of the base.

The perimeter of the prism is (3+4+5) cm and the height of the prism is 15 cm.

So, the lateral surface area of the prism is:

[tex]LSA=(3+4+5)\times 15[/tex]

[tex]LSA=(12)\times 15[/tex]

[tex]LSA=180[/tex]

Therefore, the lateral surface area of the prism is 180 square cm.

Answer:

New avaerage if 2 students (15 year old) left = 13

Step-by-step explanation:

Given:

Average age of 20 students = 13.2

Find:

New avaerage if 2 students (15 year old) left

Computtaion:

Sum of all 20 student's age = 20 x 13.2

Sum of all 20 student's age = 264

Sum of current 18 student's age = 264 - 15 - 15

Sum of current 18 student's age = 234

New avaerage if 2 students (15 year old) left = 234 / 18

New avaerage if 2 students (15 year old) left = 13

Answer:

Capacity of Matti's green house = 367.5 cubic feet

Step-by-step explanation:

Given:

Base Width and Length = 7 feet by 15 feet

Height of prism = 7 feet

Find:

Capacity of Matti's green house

Computation:

Capacity of Matti's green house = Volume of rectangular base[triangular prism]

Volume of rectangular base[triangular prism] = Area of triangular base x Height

Capacity of Matti's green house = [(1/2)(7)(7)][15]

Capacity of Matti's green house = [(1/2)(49)][15]

Capacity of Matti's green house = [(24.5)][15]

Capacity of Matti's green house = 367.5 cubic feet

Answer:

$318

Step-by-step explanation:

Calculation to determine the predicted end-of-year value of a portfolio

Given expression 1.08s + 1.02b

Now let determine the Predicted end-of-year value

Predicted end-of-year value=1.08(200) +1.02(100)

Predicted end-of-year value=216+102

Predicted end-of-year value=$318

Therefore the predicted end-of-year value of a portfolio will be $318

Answer:

When you fold the number line ( vertically through the point zero on the number line ) you have successfully divided the number line into 2 equal halves.

Step-by-step explanation:

When you fold the number line ( vertically through the point zero on the number line ) you have successfully divided the number line into 2 equal halves. and this causes the points labelled on either side of the number line  to match up with with the points on the opposite side

Answer:

B - 6sqrt(23) ft.

Step-by-step explanation:

Area = (Side)^2 = 828.

Side = sqrt(828) = sqrt(36*23) = 6 sqrt(23).

So B - 6sqrt(23) ft.
