Answer:
[tex]P(Yellow\ or\ Green) = 0.524[/tex]
Step-by-step explanation:
Given
[tex]Yellow = 5\ seconds[/tex]
[tex]Green = 50\ seconds[/tex]
[tex]Red = 50\ seconds[/tex]
Required
Determine the probability of Green or Yellow
First, we need to determine the total time
[tex]Total = 50 + 50 + 5[/tex]
[tex]Total = 105\ seconds[/tex]
Next, is to determine the required probability
This is calculated as follows:
[tex]P(Yellow\ or\ Green) = P(Yellow) + P(Green)[/tex]
[tex]P(Yellow\ or\ Green) = \frac{n(Yellow)}{Total} + \frac{n(Green)}{Total}[/tex]
[tex]P(Yellow\ or\ Green) = \frac{5}{105} + \frac{50}{105}[/tex]
[tex]P(Yellow\ or\ Green) = \frac{5 + 50}{105}[/tex]
[tex]P(Yellow\ or\ Green) = \frac{55}{105}[/tex]
[tex]P(Yellow\ or\ Green) = 0.52380952381[/tex]
[tex]P(Yellow\ or\ Green) = 0.524[/tex] -- Approximated

CAN ANYONE ANSWER MY QUESTION ASAP The diameter of a cylinder is 5 yd. The height is 4 yd. Find the VOLUME of the cylinder
Answer:
78.54 (rounded to 2 d.p)
Step-by-step explanation:
The formula for the volume of cylinder is πr(squared)h
Radius is half of the diameter so 5/2 = 2.5
The height is 4
Therefore,
π x 2.5 x 4 = 78.53982

Answer:
m = 5
p = 10
Step-by-step explanation:
Part A
The dashes on the lines mean that the lines are equal in length.
Therefore, IJ = IH and HK = KJ
So as IJ = IH
⇒ 10 = 2m
⇒ m = 10 ÷ 2
⇒ m = 5
Part B
The line IK is the bisector of angle I since IJ = IH and HK = KJ
Therefore, 2p - 5 = p + 5
subtract p from both sides:
⇒ 2p - 5 - p = p + 5 - p
⇒ p - 5 = 5
Add 5 to both sides:
⇒ p - 5 + 5 = 5 + 5
⇒ p = 10

The equation of line is y = ( 3/2 )x - 7 , where the slope is m = 3/2
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = 3/2
The y-intercept is b = -7
And , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
So , y = ( 3/2 )x - 7
Hence , the equation of line is y = ( 3/2 )x - 7

If the graph of f(x)=x2, how will the graph be affected if the coefficient of x2 is changed to 3?
Answer:
435
Step-by-step explanation:
Transformations are used to change the orientation of a function to a new function. The graph of [tex]f(x) = x^2[/tex] will have its parabola widened when it changes to [tex]g(x) = 3x^2[/tex]
Given that
[tex]f(x) = x^2[/tex]
If the new function is:
[tex]g(x) = 3x^2[/tex]
It means that f(x) has been vertically translated by a scale factor of 3.
The graph will be affected such that the parabola of [tex]f(x) = x^2[/tex] will become widen when the coefficient changes to 3 i.e. [tex]g(x) = 3x^2[/tex].

The acceleration of a Maserati (sports car) is proportional to the difference between 250 km/h and its velocity. If the car can accelerate from rest to 100 km/h in 10 s, how long will it take for the car to accelerate from rest to 200 km/h?
Answer:
a) The differential equation for the velocity is given by
(dv/dt) = k(250 - v)
b) v(t) = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾
With units of km/h
Step-by-step explanation:
Acceleration, a ∝ (250 - v)
But acceleration is widely given as dv/dt
(dv/dt) ∝ (250 - v)
(dv/dt) = k(250 - v)
where k = constant of proportionality
(dv/dt) = k(250 - v)
b) (dv/dt) = k(250 - v)
dv/(250 - v) = k dt
∫ dv/(250 - v) = ∫ k dt
- In (250 - v) = kt + c (where c is the constant of integration)
v(0) = 0; meaning, at t = 0, v = 0
- In 250 = 0 + C
c = - In 250 = - 5.52
- In (250 - v) = kt - 5.52
In (250 - v) = 5.52 - kt
250 - v = e⁽⁵•⁵² ⁻ ᵏᵗ⁾
v = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾
With units of km/h

The polynomial 3x2 – 10x 8 has a factor of 3x – 4. what is the other factor of 3x2 – 10x 8?
The other factor of the polynomial [tex]\rm 3x^2-10x+8[/tex] is ( x - 2 )
It is given that the polynomial [tex]\rm 3x^2-10x+8[/tex] has a factor of [tex]\rm (3x-4)[/tex].
It is required to find the other factor.
What is Polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have polynomial:
[tex]\rm = 3x^2-10x+8[/tex]
Now by using the factorization method:
[tex]\rm = 3x^2-10x+8\\\rm = 3x^2-6x-4x+8\\\rm =3x(x-2)-4(x-2)\\\rm = (x-2)(3x-4)[/tex]

A box contains:
3 red crayons
7 blue crayons
4 yellow crayons
8 green crayons
2 black crayons
1 orange crayon
A crayon is chosen at random and replaced 50 times. What is a reasonable prediction for the number of times a blue or orange crayon will be drawn?
Answer:
16 times
Step-by-step explanation:
We first have to find the total amount of crayons:
[tex]3+7+4+8+2+1=25[/tex]
That means that the box contains a total of 25 crayons. Of those 25 crayons, 7 are blue and 1 is orange. That means every time one crayon is chosen from the box, there is an 8 in 25 chance it will be blue or orange. We can represent that chance as a fraction: [tex]\frac{8}{25}[/tex]
That [tex]\frac{8}{25}[/tex] chance occurs each time ONE crayon is chosen, so if we want to know how many times blue or orange will be chosen after 50 times, we can multiply that chance by 50.
[tex]\frac{8}{25}*50=400/25[/tex]
Then you simplify the fraction:
[tex]\frac{400}{25}=16[/tex]
That means that if you pull crayons from the box 50 times, a blue or orange crayon will be likely drawn around 16 times.
