Answer:
60 years old
Step-by-step explanation:
A=Ashu's age. M=Ashu's Mother's Age
M=A*3
M/3 = (A*3)/3 ==> divide 3 on each side to solve for A
A = M/3
A+5 = M/3 + 5 ==> A+5=25 since that'll be Ashu's age 5 years from now
25 = M/3 + 5 => plug in 25 for A+5
25-5 = M/3 + 5 - 5 ==> solve for M
20 = M/3
M = 20 * 3
M = 60 years old
suppose that y1 and y2 are independent and that both are uniformly distributed on the interval (0,1), and Let U1 and U2 be independent uniform random variables, both on (0,1). Let Y1 = U1U2 and let Y2=U2. (a) Find the joint density of Y1 and Y2.
(b) What is the marginal density for Y1?
a) The joint density of Y1 and Y2 is f(y1, y2) = 1, for 0 ≤ y1, y2 ≤ 1.
b) The marginal density for Y1 is f(y1) = 1, for 0 ≤ y1 ≤ 1.
Explanation:
(a) The joint density of Y1 and Y2 is found by multiplying the two individual densities together. Since Y1 and Y2 are independent, this is simply the product of the two densities.
The density for U1 is the same for all values of U1 on the interval (0,1), which is 1. The density for U2 is also the same for all values of U2 on the interval (0,1), which is also 1.
Therefore, the joint density of Y1 and Y2 is:
f(Y1,Y2) = f(U1U2,U2)
= f(U1) x f(U2)
= 1 x 1
= 1
(b) The marginal density for Y1 is the density of Y1 without regard to Y2. Since Y2 is uniform on (0,1), we can integrate the joint density over the interval (0,1) to obtain the marginal density of Y1:
f(Y1) = ∫f(Y1,Y2)dY2
= ∫1dY2
Y2 = 1
Therefore, the marginal density of Y1 is 1

The length of a rectangle is three times its width. If the perimeter of the rectangle is 40 m, find its length and width.
Answer:
The width would be 5, and the length would be 15.
Step-by-step explanation:
To solve this problem, first look at the perimeter. If the perimeter of the rectangle is 40m, then we can now solve the problem.
Since we don't know the width or the length, first, say that the width is w.
Width=w
Now, since the length is three times the width, we can write 3w for the length.
Length=3w.
Now, combine like terms.
w+3w+w+3w=40
8w=40
Divide by 8 on both sides.
40/8=5
w=5.
Since now we know that the width is 5, plug in 5 for w.
3(5)=15
w=5
The width would be 5, and the length would be 15.
Hope this helps! Have a great day! :D
Answer:
Length = 15 m Width = 5 mStep-by-step explanation:
Let us assume that,
→ Perimeter = 40 m
→ Width = x
→ Length = 3x
Perimeter of rectangle formula,
→ P = 2(l + w)
Forming the equation,
→ 2(3x + x) = 40
Now the value of x will be,
→ 2(3x + x) = 40
→ 2(4x) = 40
→ 8x = 40
→ x = 40/8
→ [ x = 5 ]
Then the length and width is,
→ Width = x = 5 m
→ Length = 3x = 3(5) = 15 m
Hence, these are the answers.
Emma has $140 cash to spend at a music store. How much can she spend on items if there is %7 sales tax?
Answer:
$130.84
Step-by-step explanation:
If a 7% sales tax is applied, the cost of the item (including tax) will be 107% of the original price.
To calculate how much Emma can spend if she has $140 cash to spend, divide $140 by 107%:
[tex]\implies \dfrac{140}{107\%}[/tex]
[tex]\implies \dfrac{140}{\frac{107}{100}}[/tex]
[tex]\implies 140 \times \dfrac{100}{107}[/tex]
[tex]\implies \dfrac{14000}{107}[/tex]
[tex]\implies 130.84[/tex]
Therefore, Emma can spend $130.84 on items if there is a 7% sales tax.

The graph of the given proportional relation shows that the line passes through the point (0, 0) and continues through the point (15, 5). The relation is represented by the equation y = -0.33x. So, option A is correct.
What is the proportional relationship of the given table of proportions?The given table shows the x and y coordinates of a line.
So, we can find the relationship among them by writing an equation from the given points as
y - y₁ = {(y₂ - y₁)/(x₂ - x₁)} × (x - x₁)
Here we have (x₁, y₁) = (15, 5); (x₂, y₂) = (9, 3)
⇒ y - 5 = (3 - 5)/(9 - 15) × (x - 15)
⇒ y - 5 = (-2)/(-6) × (x - 15)
⇒ y - 5 = 1/3 × (x - 15)
⇒ 3y - 15 = x - 15
⇒ 3y = x + 0
∴ y = 0.33x
Thus, the equation for the given proportions is y = 0.33x.
Since the line is in the form of y = mx, it passes through th point (0, 0) and continues through the point (15, 5).

Step-by-step explanation:
So in this problem you're given the table at the top for your values of X is going across their corresponding P of X values and their corresponding Q of X values. So in part A we want to find P fq of X. So first off we're gonna start when X is equal to zero. So that would mean we want to find p. of Q. of zero. So remember you start with your inside function. Well Q of zero is equal to zero. So now we need to find P. Of zero which is equal to three. Alright so next we want to find when X is one. So we have P of Q of one. Well Q of one is equal to one and I'm sorry that would leave us with PS one and PS one happens to also be one. So that'll be value for one. Next for one. X. is to so api of Q of two. Well Q two is equal to four and then P. Of four. That would leave us a pr four and pr four is equal to five. So that will be our answer for the next one. It will be five. Alright, next for three. So we have p. of Q. of three. So we have two of three which is equal to two. So now sorry that should be a P. Then we find P. F two which is also to So that'll be the answer to the 3rd 1 Next we need it for four. So we're looking for p of Q of four. Well looking according to our thing. Q4 is equal to five and then we have to find P. Of five which is zero. And lastly for five. So first we'll start with p. of Q. of five. So Q. A. Five we're told is three. So then we have to find pf three which is equal to four. So that's how you would find your first values. Okay, So now part B. We want to find sfx but no, this is the opposite way this time it's Q. A. P. Of X. So when X zero, we're going to be looking for Q. Of P. Of zero. Well no this P. Of zero is equal to three. So then we have to find Q. of three which is equal to two. It'll be our first answer. Next we'll do one. So we're gonna have Q. Of P. Of one. Well p. of one is equal to one. So then we find Q. Of one which is also one. So bring that down. All right, so now for two. First we're gonna start with Q. A. P. F. Two. Well P. F two is two. So that means we're essentially just finding Q. Of two which is four. Alright, next for three. So you're gonna have cute Of p. of 3? Well p of three is equal to four And Q four is equal to five. So I'll be your answer there. I'll do a new color because I think we're running out of room here. So next we're doing for, so I'm gonna go right here. So we're gonna have Q. A. P. Of four. Well if you four is equal to five, so that means we have to find Q. Of five which is three. And lastly for five. So we're gonna have Q. A. P. Of five. So first we'll find PFE which is zero. So that means now we need Q. Of zero which is zero. And now we filled out both of your tables.

take the van der pol equation . (a) set and . convert the above second order differential equation to a two dimensional system of differential equations:
The van der Pol equation which is a second-order differential equation is given by
d²x/dt² - μ(1 - x²)dx/dt + x = 0
Here we are asked to convert it to a two-dimensional system.
Here we need to set y = dx/dt, where y represents the system's velocity.
Hence we will rewrite it as
d²x/dt² = μ(1 - x²)y + x
Now if we set the derivatives of x and y with respect to time to be equal to different variables we get
dx/dt = y
dy/dt = μ(1 - x²)y + x
Hence we get the above systems of equations as the 2-dimensional representation of the Van der Pol equation where x and y represent the system's position and velocity respectively.
If we set μ = 1 and x = 0, then we get
dx/dt = y
dy/dt = y
Hence we get the system of differential equations representing the behavior of the van der Pol equation with μ = 1 and x = 0 in two dimensions.

What is the total number of miles she biked?
Enter your answer as a number like this: 42
The total Number of miles she biked, was 216.
In the given question, over 18 days, Sophia rode her bike an average of 12 miles each day.
We have to find the total number of miles she biked.
As we know that average is the sum of all numbers divide by total numbers.
As from the question, there is a total average of 18 days.
So the total number of days is 18.
The average distance of her bike for one day is 12 miles.
So we have to find the total number of miles that she biked.
We can find the total number of miles by multiplying the total number of days with the average speed of one day. So;
Total Number of Distance = Total Days × Average Speed of One Day
Total Number of Distance = 18 × 12
Total Number of Distance = 216 miles.
So, the total Number of Distance she biked, was 216 miles.

the vehicle can drive at 30 kph over the terrain and at 120 kph on the
road, how far down the road should the vehicle aim to reach the road
to minimize the time it takes to reach the hospital?
The final distance is 31 km.
Time, t = Distance, d/Velocity, v
Let's assume the ambulance drives a distance of x along the road, which leaves us 50-x on the road, after which it has reached the road.
It forms a triangle, after which we can use Pythagoras Theorem.
Using it, we get distance down the hill, d1, and we can calculate distance on the road remaining till the hospital, d2.
t = d1/v1 + d2/v2
= [tex]\frac{\sqrt{x^{2} + 30^{2} } }{30} + \frac{50 - x}{120}[/tex]
We need to minimise t. Therefore, we have to differentiate.
On differentiating and equating it to 0, we get the value of x as [tex]\sqrt{60} = 7.75[/tex]
How far down the road should the vehicle aim to reach the road to reach the hospital at the minimum time?
[tex]= \sqrt{900 + 7.75^{2} } = 31 km[/tex]
Thus, the final distance is 31 km.

In detail please I’m getting graded and can’t find the answer
Answer:
x = 75
y = 15
Step-by-step explanation:
What you need to know to solve this question:
1. Angles in a triangle sum up to 180
2. Angles on a straight line add up to 180
3. A right-angle is 90
4. The triangle illustrated is a right-angle triangle
Solving for x:
According to principle 2:
x + 105 = 180
x = 180 - 105
x = 75
Solving for y:
According to principles 1 and 3:
x + y + 90 = 180
(75) + y + 90 = 180
y = 180 - 90 - 75
y = 15
Graph the solution to this inequality on the number line. 2/3z > 4/5
The solution to the inequality, 2/3z > 4/5, is calculated as z > 1.2. See attachment for the graph of the solution.
How to Solve and Graph the Solution to an Inequality?The solution to an inequality is determined by finding he value of the variable in the inequality that will make it true.
Given the inequality, 2/3z > 4/5, isolate the variable z to one side to determine its value:
2/3z > 4/5 [given]
Multiply both sides by 3/2:
2/3z × 3/2 > 4/5 × 3/2
z > (4 × 3) / (5 × 2)
z > 12 / 10
Simplify further:
z > 6/5
z > 1.2
The solution is z > 1.2. The graph of the solution is shown in the image that is given in the attachment below.

given sales for the year of $218,000, cash expenses of $92,000 and depreciation expense of $23,000, net cash flow for the year is blank . multiple choice question. $195,000 $126,000 $103,000 $218,000
Answer:
$126,000
Step-by-step explanation:
The net cash flow for the year is $103, 000.
What is Net cash flow?After all debts have been settled, net cash flow can represent either a gain or a loss in money over a time period. A company is said to have positive cash flow if, after paying all of its operational expenses, it still has cash left over.
We have,
Sales for the year = $ 218, 000
Cash expenses = $92, 000
Depreciation Expenses = $23, 000
So, the Net cash flow is
= 218,000 - (92, 000 + 23, 000)
= $ 103, 000.
