Answer:
x = 1, y = 20
Step-by-step explanation:
The question is asking the length of two wires, so instead of area, we are looking at the perimeter.
For the triangle, the equation looks like this:
(2-x) + 15 + y
For the rectangle, the equation looks like this:
(5-x) + (y-6) × 2
Let's say that x = 2, and y = 12.
The triangles new equation would look like this:
(2-2) + 15 + 12 = 27
The rectangles new equation would look like this:
(5-2) + (12-6) × 2 = 18
The wires are the same length, so these numbers can't be correct.
Let's say that x = 1 and y = 20.
The triangles new equation would look like this:
(2-1) + 15 + 20 = 36
The rectangles new equation would look like this:
(5-1) + (20-6) × 2 = 36
These numbers are the same, so therefore the answer is
x = 1 and y = 20.

New game You pay 10 and roll a 6 die. If you get a you win 50 If not, you get to roll again. If you get a 6 this time, you get your 10 back.a) Create a probability model for this game.b) Find the expected value and standard deviation of your prospective winnings.c) You play this game five times. Find the expected value and standard deviation of your average winnings.d) 100 people play this game. What's the probability the person running the game makes a profit?
The probability mode for the given value is created. The expected value and standard deviation of prospective winnings are -$0.28 and $18.33. The expected value and standard deviation if the game is played five times are -$1.40 and $40.99. The probability that the person running the game makes a profit is 0.561.
Probability is a way to determine how likely something is to happen. It is computed by dividing the frequency of the event by the total number of outcomes. The formula then becomes P(X) = frequency of the event÷total number of outcomes.
The product of the probabilities determines the likelihood that two or more occurrences will coincide. This is given by, P(A and B) = P(A)P(B).
a) To create a probability model follow the steps. Let X is an occurrence of an event. The table is attached here.
b) The expected value is calculated using the formula, E(X) = μ = ∑ x P(x).
[tex]\begin{aligned}E(X)=\mu&=x_1p_1+x_2p_2+x_3p_3\\&=40\left(\frac{1}{6}\right)+0\left(\frac{5}{36}\right)+(-10)\left(\frac{25}{36}\right)\\&=-\$ 0.28\end{aligned}[/tex]
Also,
[tex]\begin{aligned}E(X^2)&={x_1}^{2}p_{1}+{x_2}^{2}p_{2}+{x_3}^{2}p_{3}\\&=(40)^2\frac{1}{6}+(0)\frac{5}{36}+(-10)^2\frac{25}{36}\\&=(1600)\frac{1}{6}+(0)\frac{5}{36}+(100)\frac{25}{36}\\&=266.67+69.44\\&=336.11\end{aligned}[/tex]
And the standard deviation is calculated using the formula, σ=√Var[X].
[tex]\begin{aligned}\sigma=\sqrt{\text{Var}(X)}&=\sqrt{E(X^2)-E(X)^2}\\&=\sqrt{336.11-0.08}\\&=\sqrt{336.03}\\&=\$18.33\end{aligned}[/tex]
c) The expected value and standard deviation for playing the game 5 times are calculated as follows.
The expected value is,
[tex]\begin{aligned}5\times E(X)&=5(-\$0.28)\\&=-\$1.40\\\end{aligned}[/tex]
The standard deviation is,
[tex]\begin{aligned}\sigma&=\sqrt{5\times\tex{Var}(X)\\&=\sqrt{5\times336.03\\&=\sqrt{1680.15}\\&=\$40.99\end{aligned}[/tex]
d) The dice rolling is random and the winning chance is independent. The probability the person running the game makes a profit (P(x<0)) is given by,
The population mean, μ(Y) = -$0.28
The standard deviation for a population of 100 is,
[tex]\begin{aligned}\sigma&=\sqrt{\frac{\text{Var}(X)}{n}}\\&=\frac{18.33}{\sqrt{100}}\\&=1.83\end{aligned}[/tex]
The z-score for mean winning is,
[tex]\begin{aligned}z&=\frac{x-\mu}{\sigma}\\&=\frac{0-(-0.28)}{1.83}\\&=0.153\end{aligned}[/tex]
For a person to make a profit, the mean winning of the player should be less than the z-score. Then,
The P-value from the z-table, P(z<0.153)=0.5608
The answer is 0.561.

At 1,000 units of output, the fixed cost of production is $12,500 per week. Total cost of producing 1,000 units per week is $28,500 per week. The variable cost of producing 1,000 units of output per week is equal to _____.
The variable cost of producing 1000 units per week is equal to $16000.
Variable costs are those that change with volume. Raw materials, piece-rate labour, production supplies, commissions, shipping costs, packing costs, and credit card fees are examples of variable costs. The variable costs of production are referred to as "Cost of Goods Sold" in some accounting accounts.
Given,
Fixed cost of production per week =$12500
Total cost of producing 1000 units per week =$28500
then,
variable cost of producing 1000 units per week = 28500-12500=$16000
Thus, the variable cost of producing 1000 units per week is equal to $16000.

Suppose we observe an unending sequence of days on which the umbrella appears. show that, as the days go by, the probability of rain on the current day increases monotonically toward a fixed point. calculate this fixed point.
The probability computed is <0.8967,0.1033> which roughly shows that, as 90 days pass by, the probability that it will rain on a given day will be increasing monotonically towards a fixed point.
The chance that an event will occur ranges between 0 and 1. Where 0 shows that the event is impossible to occur and 1 shows that the event is bound to occur. If the chance of occurring an event is more than the chance of its not occurring then, it is more likely that the event will occur.
If we take the example of tossing a coin, we can say that the probability that a head will occur or a tail will occur will remain the same, i.e., 50%. The occurrence of heads or tails is equally likely.

The final two equations which represent the given situation are:
2x - y = -6 and 3x - y = -5.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a linear equation of two variables.
Suppose,
The larger number is 'y' and the smaller number is 'x'.
First relation,
'y' is equal to twice the sum of a smaller number (x) and 3. So we represent this as:
y = 2(x+3)
y = 2x + 6
2x - y = -6 ............(1)
Second relation,
The larger number (y) is equal to 5 more than 3 times the smaller number (x). So we represent this as:
y = 5 + 3x
3x - y = -5 .............(2)
Hence, the final two equations which represent the given situation are:
2x - y = -6 and 3x - y = -5.

What is the slope-point form of the line?
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
A line goes through the point (-1, 1) and (0,-3)
so the slope of the given line would be:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-3-1}{0-(-1)}\\\\m=-4[/tex]
And we have to find the line which passes through the point (-4, -3) and the required line is perpendicular to the given line.
As we know the product of slopes of perpendicular lines is -1.
So the slope of the required line would be = 1/4
By using a slope-point form of the line, we get
