8 0

Answer:

(4, 2)

Step-by-step explanation:

Start by combining the equations

2x + 2x = 4X

4y - 4y = 0

16 + 0 = 16

4x = 16

x = 4

Now that you have one variable plug it back in to one of the original equations

2(4) + 4y = 16

8 + 4y = 16

4y = 8

y = 2

Which conclusion can be drawn from the data?

Snowcat [4.5K]

Answer:

During the 10 wk period, the rainfall amount recorded most often for City B was 1 in.

Step-by-step explanation:

Given the data :

City A :

Reordered data:

0, 0.2, 0.2, 0.3, 0.4, 1, 1.3, 1.5, 2.5, 3

City B :

Reordered data:

0, 0, 0.1, 0.1, 0.2, 0.3, 0.4, 1, 1, 1

Using a calculator :

Mean Rainfall for City A = 1.04

Mean rainfall for city B = 0.41

Range : maximum - minimum

City A = 3 - 0 = 3

City B = 1 - 0 = 1

Mode (most occurring) :

City A = 0.2

City B = 1

Median :

City A = 0.7

City B = 0.25

The only true conclusion in the options given that can be drawn from the data is that ;During the 10 wk period, the rainfall amount recorded most often for City B was 1 in.

V = 4/3r3. A sphere has a radius of 3.5 inches. Volume (to the nearest tenth) =

Kobotan [32]

The correct formula of volume of sphere is:

$V = \frac{4}{3} \pi r^3$ Where r is the radius of sphere.

Given, r = 3.5 inches.

So, first step is to plug in r = 3.5 in the above formula to get the volume: V. Hence,

$V=\frac{4}{3} *3.14*3.5^3$ Since, π = 3.14

= 1.33333 * 3.14 * 42.875

= 179.5028846

= 179.5 Rounded to nearest tenth.

So, volume of sphere is 179.5 cubic inches .

Hope this helps you!

The Dimension of the Cylinder: Height = 1.5 m and radius = 0.75 m

Volume of Cylinder = 2.649 m³

Surface Area = 10.59 m²

<h3>What is Cylinder?</h3>

A cylinder is a three-dimensional solid figure which has two identical circular bases joined by a curved surface at a particular distance from the center which is the height of the cylinder.

Here, Trailer bed dimension = 1.5 m X 1.5 m

So, height of the cylindrical = 1.5 m

Radius = 1.5/2 = 0.75 m

Now, Volume of Cylinder = πr²h

= 3.14 X (0.75)²X1.5

= 2.649 m³

Surface area of cylinder = 2πrh + 2πr²

= 2πr (h + r)

= 2 X 3.14 X 0.75 ( 1.5 + 0.75)

= 10.59 m²

Thus, The Dimension of the Cylinder: Height = 1.5 m and radius = 0.75 m

Volume of Cylinder = 2.649 m³

Surface Area = 10.59 m²
