Answer:

20% probability

Step-by-step explanation:

First, we need to calculate the area of all the figures inside the rectangle.

Area of triangle= 1/2 BH

So, 3x2=(6)

Area of Square= L^2

3x3=(9)

Area of rectangle= LxW

=60.

60+9+6= 75.

75 is the total area.

Now, lets find the added area of only the triangle and square.

9+6= 15

The probability will be 15/75=

Convert into percent form

= 20%

Step-by-step explanation:

Let's call C the point on K(O) and segment AO.  I assume you're aware of a 'secant tangent angle theorem', where if you know the measure of arc BC you can solve for angle BAD.  Since CD is a diameter of the circle, the measure of arc CD is 180 degrees - with this you can easily find the measure of all arcs of the circle then apply the theorem

Answer: C) P(blue) = 70%, P(green) = 30%, P(blue and green) = 21%

Step-by-step explanation:

Given probabilities P(A) AND P(B) are independent, the probability that both events to occur is given by:

P(A)∩P(B)

thus from the example, independent events will be:

P(blue)=70%, P(green)=30%, P(blue and green)=21%

Because:

P(blue)∩P(green)=0.7×0.3=0.21=21%

Answer:

  Bulawayo

Step-by-step explanation:

Proportions can be compared numerous ways. Here, we find it convenient to look at the difference between girls and boys relative to the number of boys.

__

With 35 girls and 25 boys, there are 10 more girls than boys. 10 is less than half of the number of boys, so the ratio of girls to boys is less than 1.5.

With 35 girls and 15 boys, there are 8 more girls than boys. 8 is more than half of the number of boys, so the ratio of girls to boys is more than 1.5.

"More than 1.5" is greater than "less than 1.5", so Bulawayo has the greatest proportion of girls.
_____

Additional comment

As a fraction of the total, the proportions of girls are ...

  Harare: 35/(35+25) = 35/60 = 7/12 = 21/36

  Bulawayo: 22/(22+14) = 22/36 . . . . . . greater than 21/36.

The radius of the sphere is 4.2 feet.

A sphere is a geometrical shape in three dimension which has every point on the surface of it at an equal distance from a common point called the center of the sphere.

Volume of a sphere is given by the equation,

Volume = [tex]\frac{4}{3}[/tex]πr³, where r is the radius.

We have volume of the given sphere = 320 feet³

Substituting this value in the main equation, we get,

320 =  [tex]\frac{4}{3}[/tex]πr³

320 × 3 = 4πr³

960 / 4π = r³

960 / (4 × 3.14) = r³

r³ = 76.43

r = 4.24 ≈ 4.2

Hence, the radius of the sphere with a volume of 320 feet³ has a radius of 4.2 feet, to the nearest tenth of a foot.

The length of the railing that will fit completely around the deck is 54 feet. The area of the triangular deck is approximately 164.25 square feet.

To find the length of the railing that will fit completely around the triangular deck, we need to calculate the perimeter of the triangle. The perimeter of a triangle is the sum of the lengths of all three sides.

Since each side of the triangular deck is 18 feet long, the perimeter (P) can be calculated as:

P = 18 feet + 18 feet + 18 feet

P = 54 feet

So, the length of the railing that will fit completely around the deck is 54 feet.

Next, let's find the area of the triangular deck. The area of a triangle can be calculated using the following formula:

Area (A) = (1/2) * base * height

Since the triangle is equilateral (all sides have the same length), any side can be considered as the base, and the height can be drawn from any vertex to the midpoint of the opposite side.

Let's consider one of the sides (18 feet) as the base. Now, to find the height, we can draw a perpendicular line from the vertex to the midpoint of the base, creating two right-angled triangles.

The height (h) of one right-angled triangle can be found using the Pythagorean theorem:

[tex]h^2 = (18 feet / 2)^2 + (18 feet)^2\\h^2 = 9 feet^2 + 324 feet^2\\h^2 = 333 feet^2\\[/tex]

h ≈ √333 feet

h ≈ 18.25 feet (rounded to two decimal places)

Now, we can find the area (A) of the triangular deck:

A = (1/2) * base * height

A = (1/2) * 18 feet * 18.25 feet

A ≈ 164.25 square feet (rounded to two decimal places)

So, the area of the triangular deck is approximately 164.25 square feet.
