Answer:

The population is all 600 members of the health club

Explanation:

50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

Answer:

The correct option is;

A. A number line that goes from 95 to 103. A closed circle is at 98.6. Everything to the right is shaded.

Step-by-step explanation:

To represent x greater-than-or-equal-to 98.6 on the number line we note that an open circle stands for either a less than or a greater than, while an open circle stands for either less than or equal to or greater than or equal to

The correct way to represent x greater than or equal to 98.6 on the number line, we indicate the point 98.6 with a closed circle and we shade everything in the region of the solution which is to the right of the closed circle

Therefore the correct option is A. A number line that goes from 95 to 103. A closed circle at is at 98.6. Everyting to the right is shaded.

Step-by-step explanation:

The probability of winning $3,899 is 0.0001, which is a very small probability, but still possible.

To write the probability distribution for a player's winnings in the Pick 4 game, we need to consider all the possible outcomes and their probabilities.

There are a total of 10,000 possible four-digit numbers that can be drawn in the game. Since the player has to match the numbers in the exact order, there is only one winning combination for each four-digit number. Therefore, the probability of winning is 1/10,000.

To calculate the player's winnings, we need to subtract the $1 cost of playing from the $3,900 prize. Thus, the player's net winnings can be calculated as follows:

Net Winnings = $3,900 - $1 = $3,899

The probability distribution for the player's winnings can be summarized in the following table:

| Winnings (x) | Probability (P) |
|--------------|-----------------|
| $0           | 0.9999          |
| $3,899       | 0.0001          |

Note that the table shows the possible winnings (x) in ascending order, as requested. The probability of winning $0 is 0.9999, which means that the player is most likely to lose their $1 bet.

As a consequence of ABPC being an equilateral triangle, AB has a length of 3 centimetres and Angle AOB is 60 degrees.

In mathematics, length is a unit used to express an object's size or the separation between two locations. It is the distance between two points and is usually expressed in units like meters, centimeters, feet, or inches. In addition to higher-dimensional objects like a rectangular solid or a cylinder, length can also apply to one-dimensional objects like a line segment or a curve. One of the basic ideas in geometry is length, which is extensively used in a wide range of mathematical applications.

given

Angle AOB is 60 degrees because ABPC is an equilateral triangle. We know that angle COD is 60 degrees because angle AOB is a perpendicular angle to angle COD.

We are informed that the ABPD has a 273 cm2 size. Since ABPD is a trapezoid with the bases AB and PD, we can use the calculation for a trapezoid's area to determine its height:

Area of ABPD equals (bases added together) Times (height) / 2.

27√3 Equals (AB + PD) * h / 2

Since ABCD is a rhombus, we can replace PD = CD = AB/2 to get:

27√3 Equals (AB + AB/2) * h / 2

When we simplify the solution, we obtain:

h = (54√3) / (3AB Plus AB)

h = (54√3) / (4AB) (4AB)

We can now translate h into x using the calculation for an equilateral triangle's area:

(x^2√3) / 4 = (1/2) * AB * (54√3) / (4AB) (4AB)

When we simplify the solution, we obtain:

x^2 = 27

x = √27

x = 3√3

As a consequence of ABPC being an equilateral triangle, AB has a length of 3 centimetres and Angle AOB is 60 degrees.

The complete question is:-   In the given diagram, ABPC is an equilateral triangle and ABCD is a rhombus. If the area of ABPD is 27√3 cm2, find the length of AB.

The height of the object at time (t) = 2 seconds is equal to 1,774 feet. Also, the height of the object at time (t) = 6 seconds is equal to 1,262 feet.

In order to determine the height of this object, we would have to substitute the amount of time taken by the object when dropped from top of the bridge into the polynomial function that models the height of the object at time (t) as follows:

P(t) = -16t² + 1838

At time = 2 seconds, we have:

Height, P(t) = -16t² + 1838

Height, P(2) = -16(2)² + 1838

Height, P(2) = -16(4) + 1838

Height, P(2) = -64 + 1838

Height, P(2) = 1,774 feet.

At time = 6 seconds, we have:

Height, P(t) = -16t² + 1838

Height, P(6) = -16(6)² + 1838

Height, P(6) = -16(36) + 1838

Height, P(6) = -576 + 1838

Height, P(6) = 1,262 feet.

Answer:

not sure explain it better please

Answer:

x = 2 , y = - 1

Step-by-step explanation:

2x + 6y = - 2 → (1)

- 6x - 8y = - 4 → (2)

multiplying (1) by 3 and adding to (2) will eliminate x

6x + 18y = - 6 → (3)

add (2) and (3) term by term to eliminate x

(- 6x + 6x) + (- 8y + 18y) = - 4 - 6

0 + 10y = - 10

10y = - 10 ( divide both sides by 10 )

y = - 1

substitute y = - 1 into either of the 2 equations and solve for x

substituting into (1)

2x + 6(- 1) = - 2

2x - 6 = - 2 ( add 6 to both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Answer:

40 people

Step-by-step explanation:

First thing, you have to find the area below the 40 - 55 line in the histogram. The area can be find using the area of a rectangle: side × side

Doing this you'll find an area of 60.

After that, find the total area of the histogram in the same way: separate it in rectangles and use the formula for the area of a rectangle, and after you'll find a total area of 100

Now you have to do a rule of three:

We know from the question statement that the amount of people with 40 - 55 years old is 25, and that area correspond to 60, so:

60 ------- 24

100 ------- x

60•x = 24•100

60x = 2400

x = 2400/60

x = 40

After solving the equations, the cost of parasailing will be 99.75 and the cost of surfing will be equal to 75.25.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both.

Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

The given information in the question is,

Assume the cost of parasailing is x and the cost of surfing is y.

x + y = 175

Total number of people in Parasailing = 16 people

Total number of people in Surfing = 20 people

Total collection done by resort = $3,101

16x + 20y = 3,101

So, the equations will be,

16x+20y=3,101            (i)

x + y = 175                  (ii)

Now, multiply the equation (ii) by 16 and solve the equation,

16x+20y=3,101

16x+16y= 2,800

4y = 301

Now, find the value of y,

y = 301/4

y = 75.25

Then, the value of x will be equal to,

x + y = 175

x+75.25 =175

Solve for x:

x=175-72.25

other so -x-6=x-4 add x to both sides -6=2x-4 add 4 to both sides 2x = -2 simplify by divide by 2 so x=-1

Answer:

Take the second equation and add 4 to both sides, this gives you x=y+4. The plug in y+4 on the first equation, so y=-(y+4)-6, distribute the negative to everything inside the parentheses, and you get y=-y-4-6. Combine like terms and you get y=-y-10, then add y to both sides, you get 2y=-10, divide both sides by 2 and you get y=-5.

Then plug -5 into the second equation and you get -5=x-4, add 4 to both sides and you get -1=x.

The linear equation passing through both points is:

f(x) = 8x - 14 ,the quadratic equation passing through both points is:

\(f(k) = -1/28k^2 + 17/14k - 36/7\)

Linear Equation:

f(x) = mx + b

Where, m is the slope and b is the y-intercept.

Calculation:

By substituting the two points (3,2) and (7,18) in the equation, we get:

2 = 3m + b

18 = 7m + b

Solving the equation we get:

m = 8

b = -14

Therefore, the linear equation passing through both points is:

f(x) = 8x - 14

Quadratic Equation:

f(k) = ax^2 + bx + c

Where, a, b and c are constants.

Calculation:

Substituting the two points (3,2) and (7,18) in the equation, we get:

2 = a(3)^2 + b(3) + c

18 = a(7)^2 + b(7) + c

Solving the equation we get:

a = -1/28

b = 17/14

c = -36/7
