Answer: [tex]\dfrac{1}{7}[/tex]

Step-by-step explanation:

Given

A cube is rolled 84 times

2 occurred 12 times

Experimental probability is determined by the use of data obtained in the experiment.

Therefore, the experimental probability of obtaining 2 on 84 rolls of the die is

[tex]\Rightarrow P=\dfrac{12}{84}\\\\\Rightarrow P=\dfrac{1}{7}[/tex]

Answer:

2292.9936

Step-by-step explanation:

circular plate had a diameter of 10 cm. The rectangular table it sits on

has dimensions of 5000mm x 3600mm. How many plates can fit on this

table? What is the percentage they cover?

Please help me it’s 10 points also this is my first time on this app

Given :

Dimension of table :

5000 mm * 3600 mm

Area of rectangle = Length * width

Area of table = 5000 * 3600

Area of table = 18000000 mm²

Recall :

1 cm = 10 mm

Diameter of circular plate = 10cm

Converting to mm :

10 * 10 = 100 mm

Area = diameter/ 2 = 100 mm / 2 = 50 mm

Area of a circle = πr²

Area of circular plate = 3.14 * 50² = 7850 mm²

Number of plates = 18000000 / 7850

= 2292.9936 plates

About 2293 plates

Answer:

The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.

Answer:

Obtuse.

Step-by-step explanation:

If we have a vector v = (a, b, c)

The magnitude of the vector is:

|v| = √(a^2 + b^2 + c^2)

And the dot product of two vectors:

v = (a, b, c)

w = (c, d, e)

is:

v.w = |v|*|w|*cos(θ) = a*c + b*d + c*e

With that relation, we can find the angle between the two vectors.

In this case, we have:

v = ⟨−1,0,1⟩

then:

|v| = √( (-1)^2 + 0^2 + 1^2) = √2

And:

w = ⟨4,5,2⟩

then:

|w| = √( 4^2 + 5^2 +2^2) = √116

Then:

v.w = (√2)*(√116)*cos(θ) =  (-1)*(4) + 0*5 + 1*2

(√2)*(√116)*cos(θ) = -4 + 2 = -2

(15.23)*cos(θ) = -2

cos(θ) = -2/15.23

θ = Acos( -2/15.23) = 97.5°

Then the angle is larger than 90°, so the angle is obtuse.

Answer:

Cada ángulo central tiene una medida de 40°.

Step-by-step explanation:

Un ángulo interno en un polígono regular comprende dos ángulos contiguos de igual medida de dos triángulos contiguos. Si el polígono regular tiene un ángulo interno de 140°, entonces cada triángulo tiene dos ángulos de 70°. El tercer ángulo corresponde al ángulo central. Por Geometría sabemos que la suma de las medidas de los ángulos internos de un triángulo es igual a 180°, entonces tenemos que la medida del ángulo central es:

[tex]\alpha = 180^{\circ} - 70^{\circ} - 70^{\circ}[/tex]

[tex]\alpha = 40^{\circ}[/tex]

Cada ángulo central tiene una medida de 40°.

Answer:

42

Step-by-step explanation:

  rectangle =  8x9 = 72

1/3 0f 72 =  24      (72-24=  48)

1/8 of 48 =6   48-6 =42

red-----24

green-----6

unpainted-----42

24+6+42+=72

The 42 squares are left unpainted.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The area of rectangle =  8 x 9 = 72

One-third of these squares are painted red, 1/8 of the remaining squares are painted green, and the others are left unpainted.

1/3 of 72

1/3 x 72 =  24      

(72-24=  48)

1/8 of 48

1/8 x 48 = 6  

( 48-6 =42)

So,

red = 24

green = 6

unpainted = 42

The 42 squares are left unpainted.
