It would be 1/2 because there are 4 different possibilities of the two coins landing and exactly 2 of them have exactly only one side up thus concluding in the answer being 50%.

1/4 the probability of the 1st coin is 1/2 for landing on tails and for the second coin, the probability is 1/2 for it not to land on tails so u do 1/2* 1/2 and u get 1/4

KATRIN_1 [288]

Answer:

21.11 ft

Step-by-step explanation:

This question would be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

13.4² + b² = 25²

179.56 + b² = 625

b² = 625 - 179.56

b = 445.44

find the square root of 445.44

b = 21.11 ft

Make sure it's fully reduced.<br><br> 2 - x = 5/8
postnew [5]

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, subtract 2 from both sides

2 (-2) - x = (5/8) - 2

-x = 5/8 - 2

Make sure they have the same denominator. Remember that what you multiply to the denominator, you multiply the numerator:

-x = 5/8 - 16/8

-x  = - 11/8

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-11/8)/-1

x = 11/8

11/8 is your answer for x

Which of the following is a result of the construction of a median of a triangle?
antoniya [11.8K]

Answer:

1)An angle of the triangle is bisected.

ONLY IN ISOSCELES AND EQUILATERAL TRIANGLE.

2) A perpendicular segment is created from a vertex to the opposite side.

True

3)A side of the triangle is bisected.  TRUE

4) The center of the triangle is found.  TRUE

The point where three medians meet inside the triangle, that point is the centroid of the triangle.

Step-by-step explanation:

Median of  a triangle is defined as the perpendicular line drawn from one vertex of a triangle to the opposite side.

It divides the side of the triangle into two EQUAL PARTS.

If the given triangle is an isosceles or an equilateral triangle, median is also an ANGLE BISECTOR

The given statements implies

1)An angle of the triangle is bisected.

ONLY IN ISOSCELES AND EQUILATERAL TRIANGLE.

2) A perpendicular segment is created from a vertex to the opposite side.

True

3)A side of the triangle is bisected.  TRUE

4) The center of the triangle is found.  TRUE

The point where three medians meet inside the triangle, that point is the centroid of the triangle.

Find the area of the shaded region. Round your answer to the nearest hundredth.
PilotLPTM [1.2K]

Answer:

4.56

Step-by-step explanation:

i see a sector hosting 2 semi circles.

this sector area will be .25 of area of circle with radius 4ft.

area of sector = .25*π*16= 4π ft^2

area of semi circle of radius 2ft = .5π*4= 2πft^2

area of 2 semicircles = 4π

the total area of sector = area of 2 semicircles - intersection area + area not covered by semi circles

4π = 4π - intersection area+area not covered by semi circles

intersection area = area not covered by semi circles

now draw a square starting from the intersection point of 2 semi circles at their upper portion. the side will be 2ft

the area of intersection will be covered in the square.

area of intersection = 2*quarter area of circle of radius 2ft - area of square

= 2*(.25π4) - 4

2π-4 = 2.28

area of intersection = area not covered by semicircle

so area of shaded region = 4.56

What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height.
igomit [66]

Answer:

That is a 30 60 90 triangle.

In such a triangle the "middle" size = short side * sq root (3)

height = 5 * sq root (3) =  8.6602540378

Area = (1/2) * 5 * 8.6602540378

Area = 2.5 * 8.6602540378

Area = 21.6506350946 square centimeters
