Answer: B. 128

Step-by-step explanation:

According to the picture, the parallel side of the trapezoid are a= 10 cm and b = (10+4+8) cm= 22 cm respectively

The perpendicular distance between these parallel sides, h = 8 cm

We know,

 Area of trapezoid = {{(a+b)×h} ÷ 2

={(10+22)×8}÷2

The answer above is correct.

Answer:

x = 8

Step-by-step explanation:

An Equilateral triangle is a triangle in which all three sides and angles are equal. The value of each angle of an equilateral triangle is 60 degrees therefore we get the equation 9x - 12 = 60

Add 12 from both sides to isolate the 9x leaving us with:

9x = 72

Divide both sides by 9 to give us x, which is

x = 8

Population dynamics must consider the number of individuals that are lost per unit of time, also called the mortality rate.

Mortality, or mortality, is a measure of the number of deaths (generally or due to a particular cause) in a particular population, scaled to the size of that population per unit of time.

The relative incidence of deaths in a particular population over a particular time period. Often expressed as the rate of human deaths or wildlife deaths from environmental hazards during a public health crisis. The highest mortality rate for patients over the age of 80 was during the last flu season.

μ-mean

σ- standard deviation

from the information given:

x=3.71

μ=86

σ=√225 = 15

hence, the probability that the sample mean would differ from the population mean by less than 3.71 WPM is

The game that is  used for the scenario above in terms of fair play is  using a balloon. Here, the player will hit the balloon.

The rule of play are:

This is a classic game with simple rules which are:

A scenario of the worksheet game whose expected value is 0 is given below:

Assume that it costs about $1 for a player to play the billon game and as such, if  the player hits a balloon, they will be given $3. what can you say. Can you say that it this game is fair or not? and who has the biggest advantage.

Solution

Note that a  game is ”fair” if the expected value is said to be 0. When a player is said to hits a balloon, their net profit often increase by $4.  So when the player do not hit a balloon, it drops to $1.

(4)(0.313) + (-1)(0.313)

= 0.939 approximately

Thus, the expected value is $0.939 which tells that the game is fair.

In order to prove that a line that is parallel to one side of a triangle divides the other sides proportionally, you can use the Cross Product Property.

If a line is parallel to one side of a triangle and divides the other two sides, those sides would be proportional to each other according to the Triangle Proportionality Theorem.

This can be shown as:

AB² = BC x BD

Where the two sides can be multiplied to get the length of the side the parallel line crossed from.

Equation

3x + 9 + 2x = x - 2x - 3              

Solution

Combine all the like terms.

3x+2x+9 =  x - 2x - 3

5x + 9 = -x - 3                            Add x to both sides of the equation

5x+x +9 = -x+x -3                      Combine

6x + 9 = - 3                                Subtract 9 from both sides of the equation

6x+9-9 = - 3-9                           Combine

6x = -12                                      Divide both sides by 6

A triangle is a three-edged polygon with three vertices. The measure of arc AB is 72°. Thus, the correct option is C.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

Since in the ΔAOB, the length of the side OA and OB are,

OA = OB = radius

Therefore, the triangle is an isosceles triangle. Thus, we can write,

∠OAB = ∠OBA = 54°

Now, the sum of all the angles of ΔAOB is,

∠AOB + ∠OAB + ∠OBA = 180°

∠AOB + 54° + 54° = 180°

∠AOB = 72°

Hence, the measure of arc AB is 72°. Thus, the correct option is C.

The height of the telescope of 1 meter and width of 20 meters gives a distance of the focus from the vertex of 25 meters.

Given that the vertex is at the origin, we have;

(h, k) = (0, 0)

The equation of a parabola is presented as follows;

(x - h)² = 4•p•(y - k)

x² = 4•p•y

When x = 10, y = 1

Therefore;

p = 10² ÷ 4 = 25

The focus of the parabola = (h, k + p)

Which gives;

The focus of the parabola = (0, 0 + 25) = (0, 25)

Answer:

y = 2

Step-by-step explanation:

Equations

7x - 7y = 7                            

-4x - 7y = - 26                          Multiply both sides of the equation by - 1

-1(-4x - 7y = - 26)

4x + 7y = 26

Solution

Add the two equations together

7x - 7y = 7      

4x + 7y = 26

11x = 33                                  Divide by 11

11x/11 = 33/11

x = 3

4x + 7y= 26                           Use this equation to solve for y. Use x = 3

4*3 + 7y = 26                        Combine the left

12 + 7y = 26                          Subtract 12 from both sides

12 - 12 + 7y = 26 - 12            Combine

7y = 14                                  Divide by 7

7y/7 = 14/7
