Visitors to a cinema are either children, adults or pensioners. The ratio for children to adult viewers is 1 : 2 The ratio of adults to pensioners is 3 : 4 A stratified example of 85 is to be taken from the cinema visitors. How many pensioners should be in the sample?
Answers
Answer:
Total number of pensioners = 40
Step-by-step explanation:
Given:
Ratio for children to adult = 1 : 2
Ratio of adults to pensioners = 3 : 4
Total number of seats = 85
Find:
Total number of pensioners
Computation:
Common ration of children to adult to pensioners
1.5 : 3 : 4

A rational expression seems to be undefined when ever the denominator is zero.
How does an expression becomes undefined?A rational expression seems to be undefined when its denominator becomes zero. Set the denominator to zero and solve the resulting equation to find the values that make a rational expression undefined.An expression in mathematics that has no meaning and thus does not have an interpretation. In the field of real numbers, for example, division by zero is undefined.Here given expression, 5/(x - 10)
The expression becomes undefined when denominator becomes 0.
So here, if x = 10 then the denominator becomes 0.
That is 5/10-10
= 5/0
which is undefined, when x = 10.
Given expression, 15/(y² + 4)
To a expression to be undefined denominator has to be 0.

A hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any other services. write a function to model the cost of services there and then determine how many services you had if you were charged $25.
Answers
The function is f(x) = 15x + 25 and you would have 6 services if you were charged $25
We know that the hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any other services, therefore:
Let x = number of services, then we can obtain the function as:
f(x) = 15x + 25 (function)
when we further solve the function, we get the answer for how many services one would have if we were charged $25,
f(x) = 15x + 25
115 = 15x + 25
90 = 15x
6 = x
Now, we know that the function is f(x) = 15x + 25 and you would have 6 services if you were charged $25

Clare ha $150 in her bank account. He buy for $200. What i clare' account balance now?
Answers
Claire's current account balance would be -$50.
The amount that Clare has in his bank account initially = $150
The amount that he used from his bank account to buy the bike = $200
As we can see that the amount that Clare used to buy the bike is more than the amount that he has in his account, therefore his account balance becomes negative, that is:
$150 - $200 = -$50
Here, it means that Clare has to pay the bank the amount of $50 that he used more than the amount that he had in his account.
Therefore, Claire's account balance would be -$50.

what is the maximum possible volume of a rectangular parcel with a square base that can be sent by priority mail
Answers
The maximum possible volume of a rectangular parcel with a square base that can be sent by priority mail would be achieved by making the length and width of the rectangle equal to the length of the square base. This is because a square has equal sides, so if we make the base of the rectangular parcel a square, then we can maximize the volume of the parcel.
We can use the formula for the volume of a rectangular prism, which is length x width x height. In this case, we want to maximize the volume of the parcel, so we need to find the values of length, width, and height that will give us the largest possible result.
Since we are given that the base of the rectangular parcel is a square, we can let the length and width be equal to the side length of the square. Let's call this value "s". Now, we need to find the height of the parcel.
We know that the maximum height of the parcel will be determined by the size restrictions of priority mail. According to the United States Postal Service, the maximum size for priority mail packages is 108 inches in combined length and girth (distance around the thickest part).
For our rectangular parcel, the combined length and girth would be equal to the perimeter of the base plus the height. The perimeter of a square is 4 times the length of one side, so the combined length and girth of our parcel would be 4s + h.
To maximize the volume of the parcel, we want to make the height as large as possible without going over the maximum size limit of 108 inches. So we can set up an equation:
4s + h = 108
Solving for h, we get:
h = 108 - 4s
Now we can plug this value into the formula for the volume of a rectangular prism:
V = s^2 * (108 - 4s)
We want to find the value of s that will give us the largest possible volume. To do this, we can use calculus to find the maximum of the function V(s). Taking the derivative and setting it equal to zero, we get:
dV/ds = 0
2s(54 - s) = 0
s = 27
So the maximum possible volume of a rectangular parcel with a square base that can be sent by priority mail would be achieved by making the base a square with side length 27 inches, and the height of the parcel would be 108 - 4(27) = 0 inches. This gives us a maximum volume of:
V = s^2 * h
V = 27^2 * 0
V = 0
Note that the parcel in this case would be flat, so it would not actually be practical for sending items. However, this calculation shows us the maximum possible volume for a rectangular parcel with a square base that can be sent by priority mail.

What is the perimeter of a parallelogram, if it's area is 36 cm^2 and the distances between the point of intersection of the diagonals and the sides are 2 cm and 3 cm? PLEASE HELP QUICK
Answers
Answer:
The perimeter of a parallelogram is 30cm.
Step-by-step explanation:
From the question , the given area of a parallelogram is 36 cm².
But the area of a parallelogram can be calculated using below formula
Area = base * height
From the question the distances that exist between the point of intersection of the diagonals and the sides are 2cm and 3cm respectively
There is the same distance between point of intersection of the diagonals and the opposite sides then,
The base of the side with 4cm can be calculated as
ha= 2+ 2= 4cm
But area can be calculated as A= base × height
36= b1 × h1
36=b1 × 4
b1= 9cm
The base of the other side can be calculated with 6cm height
h2= 3+3=6cm
A= b2× h2
36= b2 ×h2
36= b2× 6
b2= 6cm
Then the perimeter of the parallelogram can be calculated as
P= 2(b1 + b2)
= 2(6+9)
= 30cm
Hence,the perimeter of the parallelogram is 30cm

Assume you are running gradient descent, what will happen when the learning rate α is too small or too large? If you run gradient descent for 30 iterations with a=0.5 and compute J(θ) after each iteration. You find that the value of J(θ) increases over time. Based on this, how do you adjust the value of α to solve the problem?
Answers
The learning rate in gradient descent determines the step size and should be not too small or too large, as it can cause the algorithm to converge slowly or overshoot the minimum; adjusting the value of the learning rate can fix the problem, but the optimal value depends on the problem and data set.
According to the given information:
When running gradient descent,
The learning rate α determines the step size taken in each iteration toward the optimal solution.
If α is too small, the algorithm will take small steps and will converge slowly, or may even get stuck in a local minimum.
If α is too large, the algorithm may overshoot the minimum and diverge, or bounce back and forth without converging.
In the scenario described, the learning rate α of 0.5 appears too large, causing J(θ) to increase over time.
This suggests that the algorithm is not converging and is overshooting the minimum.
To fix this,
The value of α can be adjusted by reducing it to a smaller value,
Such as 0.1 or 0.01.
This should allow the algorithm to take smaller steps towards the minimum and eventually converge to a lower value of J(θ).
