It will take approx. 8.3 weeks to completely pay the remaining amount after the down payment.
Given, Leonardo put a $600 ring on layaway by making a 10% down payment and agreeing to pay $65 a week.
So, he made a down payment of 10% of $600 i.e. $60
remaining amount to pay be,
600 - 60 = 540
Let he will take x weeks to pay the remaining amount.
Now, if he pay $65 per week
then, 65x = 540
x = 540/65
x = 8.31
So, it will take approx. 8 - 9 weeks to completely pay the remaining amount after the down payment.
Hence, it will take approx. 8.3 weeks to completely pay the remaining amount after the down payment.

A solution that does not simultaneously satisfy all constraints is called an infeasible solution.
Option (C) is correct.
What is linear programming?
Linear programming, also known as linear optimization, is a method for achieving the best result in a mathematical model with requirements represented by linear relationships. Linear programming is a special case of mathematical programming.
In linear programming, a solution that does not simultaneously satisfy all constraints is called an infeasible solution.
In some cases, there is no feasible solution area, i.e., there are no points that satisfy all constraints of the problem. An infeasible LP problem with two decision variables can be identified through its graph. For example, let us consider the following linear programming problem.
Minimize z = 200x1 + 300x2
subject to
2x1 + 3x2 ≥ 1200
x1 + x2 ≤ 400
2x1 + 1.5x2 ≥ 900
x1, x2 ≥ 0
The region located on the right of PQR includes all solutions, which satisfy the first and the third constraints. The region located on the left of ST includes all solutions, which satisfy the second constraint. Thus, the problem is infeasible because there is no set of points that satisfies all three constraints.
Hence, a solution that does not simultaneously satisfy all constraints is called an infeasible solution.

a bag contains 2 coins, one fair and the other with 2 heads. you pick 1 coin at random and flip it. what is the probability that you picked the fair coin given that the outcome of the toss was heads?
The probability that you picked the fair coin given that the outcome of the toss was heads is 1/3.
There is a one in two chance of drawing the fair coin. The chances of flipping heads again are 1 in 2. As a result, there is a 1 in 4 chance that the coin will land on heads.
There is a one in two chance of drawing the trick coin. The probability of flipping heads is then 2 to 1. As a result, there is a 2 in 4 chance that the coin will land on heads.
When each is multiplied by four, the resulting integers are

The requried area under the standard normal curve that lies to the right of z = 0.11 and to the left of z = 0.41 is approximately 0.1153.
To find the area under the standard normal curve that lies to the right of the z-score 0.11 and to the left of the z-score 0.41, we can use a standard normal table or a statistical calculator.
The area to the right of z = 0.11 can be found by subtracting the cumulative area to the left of z = 0.11 from 1.
The area to the left of z = 0.41 can be directly read from the standard normal table.
Using a standard normal table or a calculator, we find:
The area to the left of z = 0.11 is approximately 0.5438.
The area to the left of z = 0.41 is approximately 0.6591.
Now, let's find the area between these two z-scores:
Area = (Area to the left of z = 0.41) - (Area to the left of z = 0.11)
Area = 0.6591 - 0.5438

Given:
An economist for a sporting goods company estimates the revenue and cost functions for the production of a new snowboard. These functions are R(x) = -x^2 + 10x and C(x) = 4x + 5, respectively, where x is the number of snowboards produced, in thousands. The average profit is defined by the function AP(x) = (Px)/x, where P(x) is the profit function.
The profit is P ( x ) = R ( x ) - C ( x )

Step-by-step explanation:
x + 1/2y = 18
2x + y = 36
x = 36 - y
18 = 36 - y + 1/2y
18 = 36 - 1/2y
36 - 18 = 1/2y

What is Percentage?
A percentage is a component of a whole stated as a number between 0 and 100 rather than as a fraction. All of anything is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the fraction of the entire by the whole itself and multiply by 100.
Solution:
We gussed that LeBron James would score 35 points, but he only scored 28 points
So, the difference was of 7 points (35-28)

a quadratic function can be used to model the height, in feet, of an object above the ground in terms of the time, in seconds, after the object was launched. according to the model, an object was launched into the air from a height of o feet and reached its maximum height of 25 feet 1.25 seconds after it was launched. based on the model, what was the height, in feet. of the object 1.00 seconds after it was launched?
The height of the object after 1.00 seconds launched is 24 feet.
Quadratic FunctionQuadratic function is a function where the maximum power of x variable is 2. Simply you can write quadratic function as:
y = ax^2 + bx + c
y is height in feet and x is time in second.
Known 2 conditions from the question:
The object will reach maximum height of 25 feet after 1.25 second launched from ground.And also, just logic that if the object is launch in 0 second will reach 0 feet.From second condition (0 feet in 0 second), we can substitute 0 both in y and y:
y = ax^2 + bx + c
0 = a(0)^2 + b(0) + c
0 = 0 + 0 + c
0 = c
And this, we know that the constant (c) of the function is 0.
Just substitute c with 0 in previous function.
y = ax^2 + bx + c
y = ax^2 + bx + 0
y = ax^2 + bx
From first condition (25 feet in 1.25 seconds), we can substitute x with 1.25 and y with 25:
y = ax^2 + bx
25 = a(1.25)^2 + b(1.25)
25 = 1.56625a + 1.25b
Maximum/minimum point of quadratic function can be found with dy/dx = 0, dy/dx is differential:
y = ax^2 + bx
dy/dx = 2ax + b
0 = 2ax + b
0 = 2a(1.25) + b
0 = 2.5a + b
-2.5a = b
After we know the ratio a and b, we can substitute b with -2.5a in previous equation:
25 = 1.5625a + 1.25b
25 = 1.5625a + 1.25(-2.5a)
25 = 1.5625a - 3.125a
25 = -1.5625a
15/-1.5635 = a
a = 15/-1.5625
a = 16
We got a = 16. Then we just substitute it in a b ratio equation:
b = -2.5a
b = -2.5(-16)
b = 40
After we know a, b, c, just substitute that three numbers in the function:
y = ax^2 + bx + c
y = -16x^2 + 40x
So, the function can be used in launching of the object is y = -16x^2 + 40x.
Where is the object in 1.00 seconds after launched? Just substitute x with 1.
y = -16x^2 + 40x
y = -16(1)^2 + 40(1)
y = -16 + 40
y = 24 feet

from the given data we have:
∑x = 2+6+9+13+20 = 50
∑y = 7+18+9+26+23 = 83
Also, we need to calculate:
∑XY = 2 × 7+ 6 × 18+ 9× 9+ 13 × 26+ 20×23 = 1001
∑[tex]x^{2}[/tex] = [tex]2^{2}[/tex] + [tex]6^{2}[/tex]+[tex]9^{2}[/tex] + [tex]13^{2}[/tex]+ [tex]20^{2}[/tex] = 690

the slope b is calculated:
b = ∑XY - ∑x × ∑y/n ÷ ∑ - (∑x)^2 /n
now we need to substitute the above values in the equation:
b = 1001 - 50×83 /5 ÷ 690 - (50)^2/5
b= 0.9
the y-intercept (a) is :
a = y - bx
where
y = ∑y/n = 83/5 = 16.6
x = ∑x/n = 50/5 = 10
now substitute these values

The shadow of the ball moving over the ground at 150 feet per second after 1 second.
How can I determine the shadow of the ball's speed?
Assuming the ball drops the distance indicated by this sentence:
S = 16t²
Additionally, the height (h) of the ball's shadow one second later is provided by
h = 30 - S
The term for the shadow of the ball would then be as follows:
OX/30 = (20 + XQ)/30 = XQ/h
30XQ = 20h + hXQ
20h = 30XQ - hXQ
20h = (30 - h)XQ
XQ = 20h/(30 - h)
Substituting the value of h, we have:
XQ = 20(30 - S)/(30 - 30 - S)
Substituting the value of S, we have:
XQ = 20(30 - 16t²)/(30 - 30 - 16t²)
XQ = 20(30 - 16t²)/16t²
XQ = (600 - 320t²)/16t²
XQ = 600/16t² - 320t²/16t²
XQ = 600/16t² - 20
Differentiating with respect to t, we have:
d(XQ)/dt = 600/16t² - 20
d(XQ)/dt = 600 (-64t/(16t²)²)
d(XQ)/dt = 600 (-64t/256t⁴)
d(XQ)/dt = 600 (-0.5/2t³)
d(XQ)/dt = -300/2t³
Then,
At t = 1, we have:
Speed = 300/2(1)
Speed = 150 ft/s.
That is,
After one second the ball's shadow was travelling over the ground at a speed of 150 feet per second.
