The required probability would be 0.57, representing getting all three cubes are the same color.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Bag 1 contains 1 yellow and 2 green cubes.
Bag 2 contains 1 yellow and 3 green cubes.
Seven cubes total would be present.
You select one cube from Bag 2 and two cubes from Bag 1 without returning the first cube.
As per the condition,
So the probability of getting all three cubes are the same color would be
⇒ (³c₂ × ⁴c₁) / ⁷c₂
⇒ (3 × 4) / 21
⇒ 12 / 21
⇒ 0.57
Therefore, the probability would be 0.57, representing getting all three cubes are the same color.

write a quadratic function in standard form whose graph passes through (-5 0) (0,-8) and (4,0).
The required quadratic function in the standard form is f(x) = -1.25 x² + 5x.
What is a quadratic equation ?
A quadratic equation is an equation which contains a single variable of degree 2 and its general form is ax² + bx + c = 0.
The x - intercepts of the quadratic equation are (-5, 0) and (0 , -8). That meant (x + 5) and (x -0) are two factors of quadratic equation.
f(x) = a (x + 5) (x - 0)
f(x) = ax² + 5x
The graph of quadratic equation passes through (4 , 0). So we need to substitute x = 4 , f(x) = 0 in equation 1.
0 = a × 4² + (5 × 4)
0 = a × 16 +20
a = -20/16
We know that quadratic equation is in form ax² + bx + c = 0.
f(x) = [tex]\frac{-20}{16}[/tex] × x² + 5x
f(x) = [tex]\frac{-5}{4}[/tex]x² + 5x
f(x) = -1.25 x² + 5x
Therefore , the required quadratic function in the standard form is f(x) = -1.25 x² + 5x.

To combine two fractions into one fraction if they are being added / subtracted from each other, make it so they share the same denominator. To do this, one way is to make [tex]\frac{1}{3}[/tex] have denominator [tex]3t[/tex], so multiply the top and bottom of the fraction by [tex]t[/tex]:
[tex]\frac{t+2}{3t} - \frac{t}{3t}[/tex]
and now you can just subtract the numerator.
[tex]= \frac{t+2 - t}{3t} = \frac{2}{3t}[/tex]

Dave and Frank are graduating and are no longer going to be roommates, but they both want to keep the dog they adopted. Using the Method of Sealed Bids, Dave bids $364 and Frank bids $568 for the dog. Since Frank's bid is higher, he gets the dog. How much will he have to pay Dave in order to keep the division fair?
The amount that Frank will pay Dave in order to keep the division fair will be $233.
How to illustrate the information?From the information, they both want to keep the dog they adopted and Dave bids $364 and Frank bids $568 for the dog.
It should be noted that the division for fair value will be:
= Number of item / Number of parties
Dave = 364 / 2 = 182
Frank = 568 / 2 = 284
Therefore, the amount that Frank will pay Dave in order to keep the division fair will be:
= (182 + 284) / 2
= 466 / 2
= $233
Therefore, the amount that Frank will pay Dave in order to keep the division fair will be $233.

11. Jim travelled at a speed of 18km/h for 2 hours. What was the distance covered?
Answer:
d = 36 km
Step-by-step explanation:
Speed of Jim, v = 18 km/h
Time, t = 2 hours
We need to find the distance covered. We know that the speed of an object is equal to the distance covered by it divided by total time taken.
[tex]v=\dfrac{d}{t}\\\\d=v\times t\\\\d=18\ km/h\times 2\ h\\\\=36\ km[/tex]
So, he will cover 36 km.

The product of −x2+5x−1 and a monomial is 4x2−20x+4.
What is the monomial?
Answer: M(x) = -4*x^0 = -4
Step-by-step explanation:
A monomial is a polynomial with only a term.
We can write a random monomial as:
M(x) = a*x^n
Where n is a natural number.
Then we know that:
(-x^2 + 5*x - 1)*a*x^n = 4*x^2 - 20*x + 4
Solving the left side, we get:
-a*x^(2 + n) + a*5*x^(1 + n) - a*1*x^n = 4*x^2 - 20*x + 4
First, we can see that the powers of x do not change after multiplying by the monomial, this means that we must have n = 0. Then we have:
-a*x^2 + a*5*x - a = 4*x^2 - 20*x + 4
The terms with equal powers of x must be equal between them, this means that:
-a*x^2 = 4*x^2
a*5*x = -20*x
-a = 4
From the last equation, (we also could get the same by solving the first or second) we get that a = -4
Then the monomial will be:
M(x) = -4*x^0 = -4

The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The expressions are given below.
[tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1
Then By simplification, we have
x - 2 = 2⁴
x = 16 + 2
x = 18
√x² + 7 = 4
x + 7 = 4
x = -3
∛(1 - x) = -1
1 - x = -1³
x = 2
The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.

The word particle can be used to describe a speck of dust, molecule, an atom or an electron. How can we avoid confusion in using the word particle?
Answer:
To avoid confusion in using the word "particle," one must state that a particle is an identifiable part of dust, a molecule, an atom, or an electron. This means that particles form these elements.
Step-by-step explanation:
For example, atoms are made up of three particles: protons, neutrons and electrons. These particles are each composed of even smaller particles known as quarks. Since quarks cannot be broken down further, they are the smallest particles known to mankind.
