Answer:

Step-by-step explanation:

Probability = Expected outcome/Total outcome of events

If a child's toy train collection contains 5 engines, 5 red cars, 7 blue cars, and 2 cabooses, the total collection will be 5+5+7+2 = 19 total collection

Note that if we are choosing this parts to make part engine, his car parts will no longer be replaced. Hence this is a problem of probability without replacement

If we randomly select pieces to make a three-part train of engine, red car and caboose, this can be chosen in that order and the following ways;

Probability of choosing  an engine = 5/19

Probability of choosing a red car = 5/18 (note that the total collection has reduced by 1 since we didn't replace the engine)

Probability of choosing  a carboose= 2/17 (the car chosen was not replaced as well)

Therefore the probability of randomly selecting pieces to make a three-part train of engine, red car, caboose is the product of the three probability calculated above i.e 5/19 * 5/18 * 2/17 = 50/5814

= 25/2907

Answer: The variable in the vertical axis (or y-axis) is the output

The variable in the horizontal axis (or x-axis) is the input.

Step-by-step explanation:

Usually, a graph of a function y = f(x) is represented in an X-Y coordinate axis.

An X-Y coordinate axis is conformed by two perpendicular lines, one vertical (y-axis) and one horizontal (x-axis)

The vertical axis (or the y-axis) is the output, and the horizontal axis (or the x-axis) is the input.

This method will work almost always, as is standardized that the x-axis corresponds to the input, and the y-axis corresponds to the output.

Answer:

D.

Step-by-step explanation:

The length of the unmarked side of the triangle is found by using Pythagoras:

x sqrt (10^2 - 6^2)

= sqrt 64

= 8.

The length of the curved part = 1/2 * pi * 10 = 5pi

Perimeter = 8 + 6 + 5pi

= 14 + 5pi

Answer:

D.  14 + 5π  inches

Step-by-step explanation:

1.  solve for the side of  a triangle using Pythagorean = [tex]\sqrt{(10^2 - 6^2)}[/tex] = 8 in.

2. circumference of a half circle = πd /2  = π*10 / 2 = 5π in.

3. total perimeter = (8 + 6) + 5π = 14 + 5π

therefore, the answer is D.  14 + 5π  inches

Probability (Roulette ball not landing on red) = 10 / 19

Step-by-step explanation:

Given:

Number of total slots = 38

Number of red slots = 18

Number of black slots = 18

Number of green slots = 2

Find:

Probability (Roulette ball not landing on red)

Computation:

Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)

Probability (Roulette ball not landing on red) = 1 - (18 / 38)

Probability (Roulette ball not landing on red) = 20 / 38

Probability (Roulette ball not landing on red) = 10 / 19

Answer:

P(x) = 3x - 150

Step-by-step explanation:

● P(x) = R(x) - C(x)

We khow that:

● R(x) = 5x

● C(x) = 2x + 150

● P(x) = 5x -(2x+150)

● P(x) = 5x - 2x -150

● P(x) = 3x - 150

The profit function of P(x)  is 3x - 150.

It is required to find profit function of P(x).

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given :

Daily revenue

R(x) = 5x where x represents the number of customers that visit the gym each day.

C(x) = 2x + 150

P(x) = R(x) - C(x)...(i)

Put the value of R(x) and C(x) in equation ..(i)

P(x) = 5x -(2x+150)

P(x) = 5x - 2x -150

P(x) = 3x - 150

Therefore, the profit function of P(x)  is 3x - 150.

Answer:

c. 4,120 pounds

Step-by-step explanation:

2 tons = 4000 pounds

1920 ounces = 120 pounds

The amount in pounds of 2 tons 1, 920 ounces by unit conversion will be 4,120 pounds thus, option (C) is correct.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

It is known that,

1 tone = 2000 pounds

2 tons = 4000 pounds

It is also known that,

1 ounce = 0.0625 pounds

1, 920 ounces = 120 pounds.

Total = 4000 + 120 = 4, 120 pounds

Hence "The amount in pounds of 2 tons 1, 920 ounces by unit conversion will be 4,120 pounds".

Answer:

Base=8 feet

Height=17 feet

Step-by-step explanation:

Let

Base=x

Height=3x-7

Area=68 square feet

Area of the sail boat=1/2 * base * height

68 = 1/2 * x * (3x-7)

Cross product

68 * 2 =(1) * (x) * (3x-7)

136 = 3x^2 - 7x

3x^2 - 7x - 136=0

Using quadratic formula

x= -b +or- √b^2 - 4ac / 2a

= -(-7) +or- √(-7)^2 - (4)(3)(-136) / 2(3)

= 7 +or- √49 - (-1632) / 6

= 7 +or- √49+1632) / 6

= 7 +or- √1681 / 6

=7 +or- 41 /6

x= 7+41 / 6 or 7-41 / 6

=48/6 or -34/6

=8 or -17/3

Answer:

Step-by-step explanation:

Let

Base=x

Height=3x-7

Area=68 square feet

Area of the sail boat=1/2 * base * height

68 = 1/2 * x * (3x-7)

Cross product

68 * 2 =(1) * (x) * (3x-7)

136 = 3x^2 - 7x

3x^2 - 7x - 136=0

Base of the boat can't be a negative value

[tex]\sqrt{61}[/tex] ≈ 7.81

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = P1(- 4, - 3) and (x₂, y₂ ) = P2(2, 2)

d = [tex]\sqrt{(2+4)^2+(2+3)^2}[/tex]

   = [tex]\sqrt{6^2+5^2}[/tex]

   = [tex]\sqrt{36+25}[/tex]

   = [tex]\sqrt{61}[/tex] ≈ 7.81 ( to 2 dec. places )

The distance between P₁ = (-4, -3) and P₂ = (2, 2) is 7.810

The distance between two points is the shortest length between two points.

Given P₁ = (-4, -3) and P₂ = (2, 2) are the two points

             is [tex]\sqrt({x_{2}-x_{1})^{2} )+({y_{2}-y_{1})^{2} }[/tex]

          Here,  (x₁, y₁) = (-4, -3) and (x₂, y₂) = (2, 2)    

           [tex]\sqrt({2}-(-4_}))^{2} )+({2}-(-3)})^{2}[/tex]          

         =[tex]\sqrt({(2+4)^{2} } +(2+3)}^{2})}[/tex]        

         =  [tex]\sqrt({6^{2} } +5^{2})[/tex]

         =  [tex]\sqrt({36}+25)[/tex]

         =  [tex]\sqrt{61}[/tex]

         = 7.810
