For positive acute angles A and B, it is known that sin A= 4/5 and tan B= 45/28 . Find the value of IIT A+B in simplest form. Question. user avatar image ...
the solution of sin(A + B) in simplest form is 27/35.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We use the trigonometric identity as;
sin(A + B) = sin A cos B + cos A sin B
Hence, we need to find cos A and cos B.
Here, We know that;
⇒ sin A = 4/5,
By use the Pythagorean identity;
sin²A + cos² A = 1
sin² A + cos² A = 1
(4/5)² + cos² A = 1
16/25 + cos² A = 1
cos² A = 9/25
cos A = 3/5
And, we can use the identity;
tan B = sin B / cos B
to find sin B:
tan B = sin B / cos B
45/28 = sin B / √(1 - sin² B)
(45/28)² = sin² B / (1 - sin² B)
sin² B + (45/28)² sin² B = (45/28)²
sin² B (1 + (45/28)²) = (45/28)²
⇒ sin B = 3/7
Now that we have sin A, cos A, sin B, and cos B,
We can put them into the formula for sin(A + B):
sin(A + B) = sin A cos B + cos A sin B
sin(A + B) = (4/5)(45/28) + (3/5)(3/7)
sin(A + B) = 27/35
Therefore, the solution of sin(A + B) in simplest form is 27/35.

which of the following is not a characteristic of the normal probability distribution? a. the total area under the curve is always equal to 1. b. the mean is equal to the median, which is also equal to the mode. c. the graph of the curve is the shape of a rectangle. d. the random variable assumes a value within plus or minus three standard deviations of its mean 99.72% of the time.
The statement that is not a characteristic of the normal probability distribution is "the graph of the curve is the shape of a rectangle."
The normal probability distribution is a continuous probability distribution that is symmetrical and bell-shaped. It is described by its mean and standard deviation, and its graph can be used to represent the distribution of a continuous random variable. The total area under the curve of the normal distribution is equal to 1, which represents the probability of observing any value within the range of the distribution.
The mean, median, and mode of a normal distribution are equal and located at the center of the distribution. This is why the normal distribution is often referred to as the "bell-shaped" distribution. The shape of the curve is a smooth, symmetrical shape that slopes gently and then becomes more steep as it approaches the tails of the distribution.
Finally, it's true that a random variable that follows a normal distribution assumes a value within plus or minus three standard deviations of its mean 99.72% of the time. This is a property of the normal distribution known as the empirical rule or the 68-95-99.7 rule.
In summary, the statement "the graph of the curve is the shape of a rectangle" is not a characteristic of the normal probability distribution, while the other statements are.
Therefore, the degrees of freedom are a feature of statistics that reflect the number of independent observations in a sample that can be used to make inferences about the population.

Solve the absolute value equation for x. |4 − 2x| + 6 = 18 Enter your answers in the blanks in order from least to greatest. x=□ or □
The solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:
x = -4 or x = 8
What is inequality?
A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement. So, 4 is a solution for example 1, while 8 is not. The solution set of an inequality is the set of all solutions.
We can solve this absolute value equation by first isolating the absolute value term on one side of the equation and then solving for both possible cases. Here are the steps:
|4 − 2x| + 6 = 18
|4 − 2x| = 12 (subtract 6 from both sides)
Now we have an absolute value equation with no constant term. We can split this equation into two cases: one where the expression inside the absolute value is positive, and one where it is negative. For each case, we can solve for x:
Case 1: 4 - 2x > 0
If 4 - 2x is positive, then we can drop the absolute value bars and write:
4 - 2x = 12
-2x = 8
x = -4
So one solution is x = -4.
Case 2: 4 - 2x < 0
If 4 - 2x is negative, then we must flip the inequality when dropping the absolute value bars:
-(4 - 2x) = 12
-4 + 2x = 12
2x = 16
x = 8
So the other solution is x = 8.
Therefore, the solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:
x = -4 or x = 8

given the linear system y[n] = 0.25y[n-1] x[n] for n > 0 and y[-1]=0 system is described by the impulse response h[n] = [0.25]nu[n]. determine if the system is stable or not
The system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.
The stability of a linear system can be determined by analyzing the magnitude of its impulse response −
|h[n]| ≤ M for some finite M
In this case, the impulse response is h[n] = 0.25nu[n], where nu[n] is the unit step function. Since the magnitude of h[n] is 0.25 for all n, the system is stable since 0.25 is a finite number that is less than any M.
To summarize, the system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.

0 and standard deviation σ0.
(a) For an uninformative prior, do we need a large or small value for σ0? [2]
(b) We want the prior probability P(|θ| ≤ A+10) to be 0.95, where A is the third-to-last digit
of your ID number. What value for σ0 should we choose? [4]
(c) A colleague prefers a Cauchy distribution as a prior. What is a possible reason for this
preference?
the data y = (y1,..., yn) are a sample from a normal distribution with unknown mean θ and known standard deviation σ = 2. Our prior distribution p(θ) is normal with mean 0 and standard deviation σ0.
y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1 y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1
We have two cases for Ф,
1. Ф=1; it implies that Pr(Ф=1)=0.5, while y~N(1,α²)
2. Ф=2; it implies that Pr(Ф=2)=0.5, while y~N(2,α²)
Now,
For 1st case of α=2,
We have marginal probability density formula
p(y)=∑p(yIФ)p(Ф)
=p(yIФ=1)p(Ф=1)+p(yIФ=2)p(Ф=2)
=N(yI1,2²)(1/2)+N(yI2,2²)(1/2)
=(1/2)[N(yI1,2²)+N(yI2,2²)]
Now.
For Pr(Ф=1Iy=1) at α=2
We have,
=p(Ф=1Iy=1)
=[p(y=1,Ф=1)]/[p(y=1)]
=[p(y=1IФ=1)p(Ф=1)]/[p(y=1)]
={(1/)exp[(-1/(2*2²))(1-1)²(1/2)]}/{(1/)(1/2)[exp[(-1/(2*2²))(1-1)²]+exp[(-1/(2*2²))(1-2)²]}
=0.53 Answer
Now, to describe the changes in shape of Ф when α is increased and decreased deviation
The formula for posterioir density is p(ФIy)=p(yIФ)p(Ф)/p(y)
=exp[(-1/(2α²)(y-Ф)²]/{exp[(-1/(2α²)(y-1)²]+exp[(-1/(2α²))(y-2)²]}
Now at Ф=1 and solving the equation, we get
p(Ф=1Iy)=1 / {1+exp[(2y-3)/2α²]}
Similarly at Ф=1 and solving the equation, we get
p(Ф=2Iy)=1 / {1+exp[(2y-3)/2α²]}
Conclusion:
α² → ∞ ⇒p(ФIy) → p(Ф) = 1/2
α² → 0 ⇒ two cases
y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1
y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1

A humane society has 73 dogs and cats to be adopted. The number of cats is 10 more than twice the number of dogs. How many of each animal is up for adoption?
Answer:
52 cats
Step-by-step explanation:
Let d be the number of dogs, then c = 2d + 10 is the number of cats.
The total number of animals is 73, so we have d + c = 73.
Substituting c = 2d + 10 into this equation, we get d + 2d + 10 = 73.
Combining like terms, we get 3d + 10 = 73.
Solving for d, we have 3d = 63, so d = 21.
Thus, there are 21 dogs and 2 * 21 + 10 = 52 cats up for adoption.
if f(x) = 14x2 − x3, what is the rate of change of f '(x) at (1, 13)?
The rate of change of f'(x) at (1, 13) is 25.
We have,
To find the rate of change of the derivative f'(x) at point (1, 13), we first need to find the derivative of the function f(x).
Given: f(x) = 14x² - x³
To find f'(x), we differentiate f(x) with respect to x:
f'(x) = d/dx (14x² - x³)
= 28x - 3x²
Now, to find the rate of change of f'(x) at x = 1,
we substitute x = 1 into the derivative expression f'(x):
f'(1) = 28(1) - 3(1)²
= 28 - 3
= 25

Generally speaking, the standard form of a quadratic function is given by ax² + bx + c = 0.
Assuming the roots of the quadratic function are a and b. Therefore, the sum of the roots of the quadratic function would be equal to -q/p;
a + b = -q/p
ab = r/p
This ultimately implies that, the nature of the roots would depend on the value of p, q and r, which make Zain's answer to be wrong.

Answer:
f(x) = 100 (3)^x <===> C
f(x) = 100 (3.5)^x <===> B
f(x) = 100 (4)^x <===> A
Step-by-step explanation:
Since the base of each of the exponential functions is the same, the higher the base, the higher up the graph will be with respect to another base with a lower value
This can be easily determined by choosing a specific value for x for each equation and seeing what the f(x) value is
Let's choose x = 2
For f(x) = 100 (3)^x, at x = 2 we get f(2) = 100(3)^2 = 100 x 9 = 900
For f(x) = 100 (3.5)^x, at x = 2 we get f(2) = 100(3.5)^2 = 100 x 12.25 = 12.25
For f(x) = 100 (4)^x, at x = 2 we get f(2) = 100(4)^2 = 100 x 16 = 1600
So for a specific value of x, the higher the base, the higher the graph is relative to the x-axis
So the matches are:
f(x) = 100 (3)^x <===> C
f(x) = 100 (3.5)^x <===> B

81000 km of black plastic cylindrical water piping with internal diameter 13 mm and walls of thickness
2 mm is required for a major irrigation project. The piping is made from bulk plastic which weighs
0.86 tonnes per cubic metre. How many tonnes of black plastic are required?
The number of tones of the black plastic that is required here is 9567.3 tones .
What is the number required?The volume of one meter of piping can be calculated as follows:
V = π * (r^2) * l
Where r is the radius of the pipe (6.5 mm), and l is the length (1 meter).
So, the volume of one meter of piping is:
V = π * (6.5^2) * 1 = 134.96 mm^3
Since 1 m^3 = 10^9 mm^3, the volume in m^3 of one meter of piping is:
V = 134.96 / 10^9 = 0.00013496 m^3
Therefore, the total volume of 81000 km of piping is:
V = 0.00013496 * 81000 * 10^3 = 11,124.16 m^3
And the total weight of the piping is:
W = V * 0.86 tones/m^3 = 9567.3 tones

Catori is a landscape photographer. One weekend at her gallery she sells a total of 52 prints for a total of $2,975. How many of each size print did Catori sell?
Answer:
15 prints
Step-by-step explanation:
Let's call the number of small prints sold as "x".
The number of medium prints sold is then (52 - x) prints.
We know that the total revenue from all the prints sold is $2,975, so we can set up the following equation:
$2975 = (x * $50) + ((52 - x) * $75)
Expanding and solving for x:
$2975 = $50x + $3900 - $75x
$2975 = $3900 - $25x
$-925 = -$25x
x = 37

In a Venn diagram, the complement of a set is represented by the region outside of the set. In the given Venn diagram, the region outside of A and B is represented by region IV, so (A union B) complement = IV.
Therefore, A and B are each represented by an oval:IV LT III regions make up the answer is (d) II.

a, P(A B) ≥ P(A). True/Falseb, If P(A B) = P(A) + P(B), then A and B are mutually exclusive. True/Falsec, If A and B are mutually exclusive events, then P(A | B) = 0. True/Falsed, P(A|B) = P(B|A) for all events A and B. True/False
P ( A or B ) ≠ P(A) + P(B) Hence, A and B are not mutually exclusive.
therefore the given condition is not true and hence statement is not true for the given events
Two events are called mutually exclusive they are independent to each other.
Also, If A and B are any two events,
Then they are called mutually exclusive,
If P(A ∪ B ) = P(A) + P(B)
Or P ( A or B ) = P(A) + P(B)
Here, P(A) = 0.37, P(B) = 0.38 and P(A or B) = 0.27
Since,
0.27 ≠ 0.37 + 0.38
⇒ P ( A or B ) ≠ P(A) + P(B)
Hence, A and B are not mutually exclusive.
therefore the given condition is not true and hence statement is not true

The values of the letters are:
A = $37.5
B = $16.95
C = 5
D = $15.34
How to determine the values of the letter?A sales tax is a tax paid to the government for the sales of certain goods and services.
Total price = Quantity * Unit Price
Unit price = Total price / Quantity
Quantity = Total price / Unit price
A = Total price = 3 * 12.5 = $37.5
B = Unit price = 33.90 / 2 = $16.95
C = Quantity = 31.00 / 6.20 = 5
15% VAT = 15% of Total Price
D = 15/100 * 108.28 = $15.34

A pancake recipe calls for `8` eggs, but Alisha only has `3` eggs. Adjust the amount needed for each ingredient in the table so that the recipe still tastes the same with only `3` eggs.
Alisha needs to use a fraction of 3/8 of each of the ingredients on the recipe.
How we need to adjust the recipe?We know that a pancake recipe calls for 8 eggs and some other ingredients.
But Alisha only has 3 eggs, so she needs to adjust the recipe.
The fraction of each one of the other ingredients that she needs to use is equal to the fraction between the number of eggs that she has and the number of eggs that the recipe calls, it is:
N = 3/8
So she needs to use 3/8 of each of the ingredients that the recipe calls.
