The probability of Ultraviolet performing fourth and Abacus performing last is 1/20.
What is probability ?Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
In a tour, five bands agree to determine the order of performance on the basis of random selection.
Since, the name of 5 bands are pulled randomly.
The probability of Ultraviolet performing fourth = 1/5
And the probability of Abacus performing last = 1/4, since 1 place is fixed for Ultraviolet.
Probability of Ultraviolet performing fourth and Abacus performing last
= 1/5 x 1/4 = 1/20
The required probability is 1/20.

Answer:
None of the Above?
Step-by-step explanation:
1.) If we put this into words, we would get -5y+7/3y=-5-8/3y-4
2.) By moving all y terms to one side, we get -5y + 7/3y + 8/3y = -5 - 4

4.) If you divide both sides by -4 2/3, you would get that y = -9 * - 3/14 = 27/14
A company produce two type of olar panel per year: x thouand of type A and y thouand of type B. The revenue and cot equation, in million of dollar, for the year are given a follow. R(x,y)=4x5y C(x,y)=x^2-3xy7y^23x-22y-4 Determine how many of each type of olar panel hould be produced per year to maximize profit
Using partial derivatives, we know that in order to optimize profit, the company should produce 7,000 type A solar panels and 8,000 type B solar panels annually.
What are partial derivatives?A function of two or more variables can yield partial derivatives.
Writing the derivative with regard to x while treating all other variables as constants allows one to determine the partial derivative of a function with respect to one variable, let's say x.
The partial derivatives for each of the other
So, for a business making two different types of solar panels, the revenue and cost functions are provided by:
[tex]\begin{aligned}&R(x, y)=4 x+2 y \\&C(x, y)=x^2-4 x y+9 y^2+22 x-114 y-5\end{aligned}[/tex]
If revenue and cost are stated in millions of dollars annually, x represents the thousands of type A solar panels produced and sold annually, and y represents the thousands of type B solar panels produced and sold annually.
By deducting costs from revenues, the profit function is obtained as follows:
[tex]\begin{aligned}&P(x, y)=R(x, y)-C(x, y) \\&P(x, y)=4 x+2 y-\left(x^2-4 x y+9 y^2+22 x-114 y-5\right) \\&P(x, y)=-x^2-9 y^2-18 x+116 y+4 x y+5\end{aligned}[/tex]
The profit function's partial derivatives with regard to x and y are as follows:
[tex]\begin{aligned}&\frac{\partial P}{\partial x}=-2 x+4 y-18 \\&\frac{\partial P}{\partial y}=4 x-18 y+116\end{aligned}[/tex]
When both of these partial derivatives are equal to zero, the profit is maximized:
[tex]\begin{aligned}&0=-2 x+4 y-18 \\&0=4 x-18 y+116\end{aligned}[/tex]
The first equation above is multiplied by two, and the two equations are then added to yield:
[tex]\begin{aligned}&0=-10 y+80 \\&y=8\end{aligned}[/tex]
Inputting into the first equation results in:
[tex]\begin{aligned}&0=-2 x+4(8)-18 \\&2 x=14 \\&x=7\end{aligned}[/tex]
Therefore, using partial derivatives, we know that in order to optimize profit, the company should produce 7,000 type A solar panels and 8,000 type B solar panels annually.

He should order 10 sandwiches of 6 foot long so, as to make sure that everyone will eat 2 pieces.
What is Conversion ?We need to convert between the units in order to ensure the accuracy and to prevent measurement misinterpretation. For example, we do not measure the pencil's length in kilometres. In this situation, one must convert from kilometres (km) to centimetres (cm) (cm). In most cases, multiplicative conversion factors are used to convert one unit to another of the same quantity. Let's see how to change the length and mass units.
1 Feet = 12 Inches
So, 6 Foot = 72 inches
The Length of sandwich- piece is 4 inch
So, when we convert 6 foot long sandwich into 4 inch,
Then we get number of piece is = 72/4 = 18
From 6 foot long sandwich we get 18 pieces of 4 inch long sub.
Now, Total people who will attend picnic is 40
and each people will eat 2 pieces.
It means total number of piece required = 2 (90) = 180
Mr. eaton required 180 pieces of sandwiches.
Number of sandwiches = 180 / 1.8 = 10
He should order 10 sandwiches of 6 foot long.

BD is perpendicular to AC, forming two right triangles. The hypotenuses are congruent, as is our leg that we will call b. If we use Law of Sines to find our angles a and c (no matter the values), we would find that because b is the same leg in both triangles and the hypotenuses are congruent, angles a and c are congruent, so therefore your missing angle in both triangles is congruent, and using a trig function will find that AD and CD are congruent, making all of both triangles congruent.

He was hoping to spend only $150 total on his gift. Target was
having a 20% off sale on their hoverboards. Can Malik afford
the hoverboard with the discount?
Using percentage formula, Malik can afford the board with the discount only if he has $120 with him
PercentageA percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
To know if Malik can afford the hoverboard, we have to calculate 20% of 150
20% of 150 = 20/100 = x /150
0.2 = x / 150
x = 150 * 0.2
x = 30
Subtracting the discount, the amount will be 150 - 30 = 120

2x =62, and the final step is to divide 2 from 62 which gets you 31.
a stone is tossed into a lake, sending out circular ripples whose area is increasing at the rate of 520 ft2/sec. how fast is the radius increasing when the radius is 30 feet?
The radius is increasing fastly at a rate of 2.75 feet per second when it is already 30 feet.
Here, it has been told that the rate of change of the area with respect to the time is = 520 ft²/sec - (i)
This can also be written as = dA/dt (ii)
We need to find the rate of change of radius with respect to the time at 30 feet. This can be written as = dr/dt (iii)
We already know that the area of a circle can be found out using the formula = πr² (iv)
Differentiating equation (ii) with respect to time, we get -
= d(πr² )/dt
= π*(dr²/dt)
= π*(dr²/dr)*(dr/dt)
= π*(2r)*(dr/dt)
= dr/dt = (dA/dt)*(1/ π*2r)
Using the given values, we get -
= (dr/dt) = 520 / π*2*30ft
= (dr/dt) = 2.75 ft/sec
Henceforth, we find that the rate of change of the radius with respect to time at 30 feet is going to be 2.75 ft/sec.
