When comparing bars side by side, they should have a consistent scale.

Use a side by side bar or a clustered bar graph to enable comparisons of individual values.

Use a stacked bar graph to highlight part to whole relationship.

Use a logarithmic scale if your audience can understand it.

Answer:

positive the line is going up and it increasing so positive association i've done this b4 trust me

POSITIVE ASSOCIATION

Step-by-step explanation:

Answer:

positive

Step-by-step explanation:

in the 1970s the population was in the 80 thousands

in 2010 it is almost in the 140 thousands

there are no points in the graph where the population was lower than where it started

the numbers keep increasing so it is positive assocation

Step-by-step explanation:

Answer:

1. 30 metres

2. 27 squared feet,

3.  25.13 cm

4. 50.27 sqared inches

5. 15.71 metres

6. 380.13 squared metres

7. Area is: 4.52 squared metres Circumference is: 7.54 metres

8. Circumference is: 47.12 feet Area is: 176.71 squared feet

Step-by-step explanation:

1. Since you're rounding pi, your calculation would be:

2 × 3 × 5 = 30

---------------------------------------------------------------------------------------------------------------

2. Since you're rounding pi, it would be:

3 × 3² = 27

---------------------------------------------------------------------------------------------------------------

3. Use the formula for number 5

---------------------------------------------------------------------------------------------------------------

4. Use the formula in number 6

---------------------------------------------------------------------------------------------------------------

5. Formula for the circumference of a circle is:

[tex]C=2\pi r[/tex]

So:

2 × 3.14 × 2.5 = 15.71

---------------------------------------------------------------------------------------------------------------

6.  Formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

So:

3.14 × 121 =  380.13

---------------------------------------------------------------------------------------------------------------

7. Use the formula for numbers 5 and 6 to figure these out

---------------------------------------------------------------------------------------------------------------

8. Use the formula for 5 and 6, except divide the diameter by 2 because the formula only works with the radius

---------------------------------------------------------------------------------------------------------------

Have a good day :)

Answer:

1. 31.4m

2. 26ft

3. 25.12 cm

4. 50.24 in

5. 15.71 meters

6. 380.13 inches

7. 7.5meters

8. 47.1 feet

Step-by-step explanation:

to find the circumference you do 2 x 3.14 x radius

to find the area you do radius squared x 3.14

Answer:

5. D  6. B  7. A

Step-by-step explanation:

it is just like a square all sides are the same

Answer:

[tex] = area \: of \: square - area \: of \: circle \\ = (s \times s) - (\pi {r}^{2} ) \\ = (24 \times 24) - (3.14 \times ( { \frac{24}{2} })^{2}) \\ \\ = 576 - 452.16 \\ = 123.84 \: square \: inches[/tex]

Answer:

2625 cubic meters

Step-by-step explanation:

the volume of a rectangle is V = length x width x height (depth in this case)

so, 50m x 30m x 1.75m = 2625m^3

Answer:

-17

Step-by-step explanation:

1) rewrite: (3 - n) divided by 2 = 10

2) Multiply both sides: (3-n)/ 2 = 10

3) move constant to the right: 3 - n = 20

4) calculate: -n = 20 - 3 then, -n = 17

5) change signs: n = -17

Hope this helped and wasn’t confusing, good luck! :)

Answer:

3.5325

Step-by-step explanation:

find the area and divide it by 2

1.5*1.5*pi= 1.5*1.5*3.14= 7.065

then divide it by two= 3.5325

Answer:

[tex]\text{1. }p<1000,\\\text{2. }p>500, \\\text{3. No, 487 does not meet Lin's inequality}, \\\text{4. Yes, 742 meets both inequalities}.[/tex]

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.
